12/14/2006: KOYONO, famous for its "Made for iPod" jackets with integrated iPod controls, is having a 30%-off-all-outerwear sale through December 18. Use coupon code OUTER30 at checkout to get the discount.
12/9/2006: Zoran Corp. has been granted US patent no. 7113609 for a "Virtual Multichannel Speaker System." The patent addresses the problem of surround simulations working better with certain hardware than others. The invention takes into account specific speaker characteristics and/or arrangements (such as the distance between the speakers, room characteristics or speaker frequency response) by modifying the virtualization algorithms to compensate for these variations. These speaker parameters can be input manually or automatically to the DSP. The MAINStage surround system from SoundMatters.com is one implementation of this patent. For more information, see US Patent 7113609.
12/5/2006: Kleer Wireless Audio announced the launch of its Kleer Audio LP line of RF wireless modules for use in small form factor battery-powered products, such as wireless headphones. These modules are capable of transmitting a lossless CD-quality digital audio stream and have 10 times the battery life of comparable Bluetooth solutions. The digital stream is embedded over a 2.4GHz RF carrier signal. Best-in-class ISM band co-existence by dynamically selecting one out of 16 narrowband channels, each of which can fit in the gaps between wireless LAN channels, and ensuring that only unoccupied channels are selected. Kleer’s Audio LP line will be exhibited at CES 2007, at the Sands Convention Center, booth no. IP209.
12/5/2006: Sony has been issued a US patent for a new type of wireless headphone: body-wired headphones. The transmitter sends the audio signal though the listener's body via an electric field. The electric field is produced and received by electrodes on the transmitter and headphones. Although the electrodes don't have to touch the skin, the patent specifies electrodes made of conductive cloth. The inventor envisions portable players and headphones worn so that the fabric touches the skin. The tiny current from the electric field is too small for the wearer to feel. For more information, see US Patent 20060252371.
11/25/2006: RadioShack.com and Radio Shack retail stores are offering headphones from Audio Technica, JVC and Koss at 30% off. (BTW, if anyone gets the Koss UR21 as a gift or otherwise, check out my Koss UR21 mod.
11/21/2006: Winter has arrived and for those of you living in colder climates, headphones and ear warmers must seem like a natural combination. The 180s Tec Stretch Ear Warmer from JVC wraps headphones and Thermolite insulation in a PolarTec fleece shell that blocks wind, rain and snow. The internal frame is adjustable for a comfortable fit. Thin enough to fit under helmets, these ear warmers collapse for storage. Other features: a volume control and 3.5-foot detachable headphone cord. Specs: 40mm transducers, 32 ohms impedance, 102dB/mW sensitivity and 100mW max. power handling.
The SoundFlip by Polar Fusion is another headphone ear warmer with an unusual feature: the earpieces have an outside flap that can be opened to let the user hear ambient sounds (such as approaching traffic) more clearly. The wrap-around headband does not interfere with open-ear helmets, hats, glasses or hairstyles. Styled more like standard neckband headphones with secure-fitting ear muffs, the SoundFlip is designed as 3-season sportswear. Specs: 28mm transducers, 24 ohms impedance, 120dB/mW sensitivity, 50mW power handling and 4-foot cord.
11/21/2006: Scott eVest is having a holiday sale. Free shipping on all orders over $75 US until Nov. 26. Of particular note: the Solar Cell backflap for SeV jackets is on sale for $150 (regular price is $200).
11/15/2006: V-Moda's Modaphones are a stylish collection of earphones with such distinction that they are being marketed as "high fashion jewelry." From the colorful Remix M-Class and noise-isolating Bass Fréq to the high-end Vibe, V-Moda has emphasized appearance, materials and an extended bass response. The Remix M-Class debuted back in March. These earphones have the classic look of earbuds, but the 15mm drivers are housed in polished metal enclosures with profiles simplified to straight lines and perfect circles. They are available in bling-bling black, hot pink and blue steel with color-matched metallic cords. The back of each Remix Modaphone is vented for a bass response down to 20Hz at up to 122dB. A soft rubber ring surrounds each earpiece for a comfortable fit and to resist moisture.
The Bass Fréq series are in-canal type earphones that seal the ear canal to reduce external noise and produce detailed sound. The lightweight plastic housings are molded with lots of curves and in 8 colors (such as hot pink, rocker red, orange camo and blue steel). Although the Bass Freq uses 10mm drivers (smaller than the Remix), it can still reproduce 20Hz at 122dB and the bass response extends down to 8Hz.
The new Vibe modaphones combine the metallic enclosures of the Remix with the noise blocking design of the Bass Fréq resulting in a decidedly sophisticated high tech design. The Vibe's transducers are smaller still at 9mm, yet the bass response is reported down to 12Hz. V-Moda chose the small transducers so that the Vibe would be micro-sized and provide a flush-fit for active lifestyles and relaxation. Other Vibe specs: 16 ohms, 92dB/mW sensitivity, 5mW max power handling. The press release says that the Vibe is only made in Gunmetal Black and FlashBlack Chrome models, but shown in the picture is a version in Gunmetal and red trim.
All Modaphones are sold with a Modawrap cable manager. Additionally, the Remix comes with 3 sets of rubber earpads and the Bass Fréq and Vibe come with 3 sizes of silicone cushions. Purchasers of the Vibe also get a leather gold pouch and VIP card access to exclusive V-MODA modcasts, music and other gear. MSRP for the Remix, Bass Fréq and Vibe respectively are $50 US, $50 US, $101 US.
11/15/2006: Do you go to sleep with a TV or music player on? Headphones aren't comfortable for sleeping, so how about pillow speakers for personal listening in the bedroom or while traveling? WestPoint Home, makers of Martex brand sheets and other bedding, have brought out the miPillow line of pillow speakers. The first is the miPillow Wireless Personal Sound System. It consists of a standard size (20" x 28") bed pillow (polyester filling, cotton cover) that has a pocket for the wireless speaker, a small, flexible volume/power control that clips onto the pillow case and a wireless transmitter, which plugs into the headphone jack of a music player or TV. It retails for $40 US. Bed Bath and Beyond has it on sale for $30.
The miPillow iPod Speaker Pillows contain therapeutic foam cores and stereo speakers with amplifier, all upholstered in a graphic plush fabric. There are two versions: the Rectangle and Neck Pillow. The Rectangle measures 4 3/4" H x 22" W x 11" D and can be used on a bed or couch or in the car. The Neck Pillow is shaped like a doughnut with an opening to wear it around the neck. It measures 5" H x 12" W x 13" D. In both pillows, there is an input jack for connecting the music player or other sound source and a pocket for three AA batteries to power the amplifier. MSRP: $60 US for the Rectangle and $50 US for the Neck Pillow. Available at Hammacher Schlemmer.
11/13/2006: The Bose In Ear earphones are in-canal types, a first in the Bose headphone line. The silicone cushions are shaped to rest gently and securely in the "outer bowl" of the ear. They remind me of the SlicSound ear molds, which did stay securely in my ears. However, I note that Bose is not touting this model for ambient noise reduction, a conspicuous omission since this is usually a benefit of in-canal earphones. The Bose cushion goes into the ear canal, but may not seal it tightly - again, very similar to the SlicSounds. Bose's TriPort feature enhances the bass response. Comes with 3 sizes of cushions and a carrying case. No other specs available. MSRP: $100 US.
11/11/2006: TR Audio is now selling headphones: AKG, Shure and Etymotic models.
11/4/2006:
A study in contrasts: HeadRoom's Max and Micro amps. The Max amps (Max and Balanced Max) belong in a home or studio system and are priced for those who can afford the best. They feature a crossfeed filter for better headphone imaging, 2-position brightness filter, 3-position gain switch to match a wider range of headphones, a rear output switch to convert the Max into a preamp and 2 headphone jacks. The amplifier/crossfeed modules use TI Burr-Brown OPA627 opamps followed by discrete "Diamond Buffer" output stages. The regulated, high current power supply is dual mono, so each channel has its own supply to minimize inter-channel interaction. Premium parts and construction are evident throughout (such as anodized aluminum enclosure, gold-plated circuit boards, stepped attenuators, mil-spec resistors and capacitors, etc.) On the rear panel are two sets of analog inputs (with a toggle selector switch), preamp outputs and a ground-lift switch to help eliminate any hum. The Balanced Max amp has separate outputs for the left and right channel (including separate grounds) and must be used with dual mono headphones (usually a custom-wiring job). Both Maxes can be outfitted with an optional DAC module. The Max amps measure around 15.5" L x 15.5" W x 5.25" H and weigh about 19 lbs.
The Micro amp (shown here with the Micro DAC) is HeadRoom's best portable amp and has twice the power rating of amps in their Mobile line. The electronics have been optimized for battery operation and are housed in a compact, black anodized, aluminum case. The front panel has switches for crossfeed, gain (3 settings) and power; a mini headphone jack and a mini input jack. An external +/-15 DC supply can be plugged into the DIN jack on the back panel or run the unit off two 9V batteries (the back panel is removable via two thumbscrews to install the batteries). The matching Micro DAC has the same power options. The Micro amp measures 1.5" H x 3.5" W x 4.5" L and weighs 9.4 oz. with batteries.
The Max and Balanced Max retail for $2999 US and $3999 US respectively. The Micro Amp and DAC are $299 US each. HeadRoom offers upgrade options for the Maxes and the Micro amp.
11/3/2006: In the last decade, headphones have become fashion accessories, sold in a variety of styles, colors and shapes to match one's mood and clothing. The Elecom EHP-AIN30 pushes the accessory concept even further - earphones as jewelry. The AIN30s have heart-shaped enclosures studded in rhinestones. Buyers can choose a housing in black or white and pink, white or blue rhinestones. These in-canal earphones have 8mm transducers and are packaged with 3 sets of cushions (small, medium, large). Specs: 16 ohms impedance, 100dB/mW sensitivity, 10mW max. power. Available at AudioCubes.com for $45 US.
11/2/2006: Billed as "the first portable 5.1 control room," Beyerdynamic's Headzone is a mobile surround headphone system for professional monitoring with virtual 5.1 channel reproduction and headtracking for increased realism. The system consists of the Headzone Base PRO (an i/o box with 6 analog inputs, firewire and USB ports, headphone jack), the DT880 Pro HT headphones (like the standard DT880 but with headtracking ultrasonic transducers on top of the headband), the Headzone Rail and Clip (these are the ultrasonic receivers that can be mounted on computer displays, walls or stands) and a software control panel (runs on Windows 2K, Windows XP and Mac OSX). The software is responsible for the surround simulation using Binaural Environment Modelling and the headtrack telemetry from the ultrasonic transducers. There are sliders, buttons and other adjustments in the control panel to construct the desired acoustic environment. The DT880 Pro HT has a standard headphone plug, so it can be used as regular stereo headphones. Beyerdynamic says that the Headzone is portable, but the base unit appears to require a 5V/2A power supply. MSRP: $2500 US.
10/31/2006: Firestone Audio has four headphone amplifiers in its line: the Little Country tube amp and three versions of the Cute solid state amp. The Little Country is a hybrid (OTL and OCL) designed around two tubes (12AX7 and 12AU7) and can be used as either a preamp or headphone amp (the rear panel has RCA preamp output jacks). There are no other circuit details, but I guess that the input stage is where the tubes do their work. The output impedance of the amp is less than 0.1 ohms, which suggests a solid state output stage. Output specs are 7Vrms at 90mA with a frequency response of 15Hz-80kHz. The Little Country measures 11cm(L) X 8cm(W) X 10cm(H). MSRP: $500 US.
The Cute solid state amps all feature selectable gain, short circuit protection and external power supply; will drive a wide range of headphone impedances; and offer a choice of 4 faceplate colors (red, blue, gray and purple). They can output 6Vrms at 500mA. The versions of the Cute amplifier are: Cute Beyond, Cute Battery and Cute Encore. The Cute Beyond is based on the TI OPA2227 opamp with a discrete class A current booster output stage. The opamps are socketed, so users can change them. The Cute Encore is an all-discrete amp in a current-feedback design. The Cute Battery appears to have a circuit similar to the Cute Beyond (except that the output stage is class AB) and can be powered by two 9V NiMH batteries or the AC adapter. The Cute amps measure 1cm (L) X 8cm(W) X 5cm(H). MSRP for all Cute amps: $170 US. Firestone Audio amps can be purchased from Firestone's website or from Wicked Digital.
10/31/2006: The Jabra BT620 is a Bluetooth-enabled wireless stereo headphone that connects to Bluetooth sources (such as music players and cell phones) supporting the A2DP (stereo) and AVRCP (remote control) profiles. The neckband style headphone has buttons and LED indicators on both earpieces. Music player controls and microphone are on the right earpiece; the telecom and volume controls are on the left earpiece. The BT620 can be set to automatically mute music when a call is received and users can easily switch between a phone call and music playback. The internal battery can be charged from an AC adapter or using the included mini USB cable connected to a PC. The headset can play music from the PC while recharging. A single charge lasts for 16 hours talk or 14 hours music streaming. It comes with a carry case and two extra sets of ear cushions. An optional Bluetooth transmitter is available for use with non-Bluetooth devices. MSRP: $90 US.
10/31/2006: The MDR-EX90SL and MDR-EX85SL lead Sony's NUDE earphone line. They are in-canal types with swiveling ear tubes. This innovation allows Sony to use larger transducers and still have the earphone seat correctly in different size ears. The EX90SL has slightly more robust specs, and the main distinguishing feature of the four versions of the EX85SL is the color of the earphone housing (black white, red and purple). Both have a 0.5m cord and a 1m extension cord. The EX990SL has 3 sets of cushions (small, medium, large) and includes a carry case. EX90SL specs: 200mW max. power, 16 ohms, 5-25,000Hz, 106db/mW sensitvity. EX85SL specs: 100mW max. power, 105dB/mW sensivity, 5-24,000Hz, 16 ohms. MSRP: 12,390 JPY for the EX90SL and 4,980 JPY for the EX85SL.
10/31/2006: The Xmod from Creative is a external sound enhancer for PC audio. It improves sound quality by expanding the dynamic range of MP3 music files and adding surround processing for stereo headphones and stereo speakers. Voices are centered in front of the listener and ambient sound appears all around the listener. Works with Windows XP (1GHz CPU, 256M RAM) and Mac OS 10.4 computers with a USB port. Comes with 32-ohm earphones. The Xmod is plug-and-play and needs no software installation. MSRP: $80 US.
Note: The X-Fi technology in the Xmod is also found in Creative's new line of X-Fi sound cards.
9/24/2006: The Philips SBC HP1000 and SHP8900 are the top headphones in Philips' HiFi line. Both have open-back earcups containing 50mm drivers with circumaural cushions and detachable cords. Visually, they differ in their distinct silver (HP1000) and black (HP8900) finishes. For comfort, the HP1000 features a "Flexi-Fit" headband which includes an adjustable cushioned inner band, while the HP8900 has a single "breathable" padded band. The HP1000 comes in its own storage box. Performance-wise, the HP1000 has a bit more top end bandwidth: 5Hz-40kHz (5Hz-30kHz for the HP8900). Other specs for both are identical: impedance - 32 ohms, sensitivity - 106dB (this spec is incomplete), power handling - 1500mW. MSRP: 130 Euros for the HP1000, 80 Euros for the HP8900.
9/18/2006: Belkin TuneTies help manage excess earphone cord. Each end of a rubber TuneTie (which is shaped somewhat like a bowtie - hence the name, TuneTie) has a slit. The cord is inserted in one of the slits, the excess is wrapped around the center of the tie and the other end is anchored in the opposite slit. TuneTies comes in packs of 3 and different sets of colors. MSRP: $13 US.
9/18/2006: The iGrado, Grado Labs' new sports headphone, started shipping this month. The neckband-style headphone is rumored to have a sound profile tweaked for listeners on the go (such as deeper bass). It is available in white or black. The plastic construction appears to be very durable. MSRP: $50 US.
9/13/2006: The Zen Aurvana from Creative is a high-end in-canal earphone from Creative Labs. The Aurvana can reproduce the entire audio frequency range, including low bass thanks to its balanced armature driver technology. The rubber cushions block out up to 90% of external noise. The product comes with a carry case and 3 sizes of cushions: 2 sets each of small, medium and large. Specs: impedance - 42 ohms, sensitivity - 115dB (this spec is incomplete) and weight - 13g. MSRP: $99 US.
8/11/2006: The SmartShare headphone splitter cable from Griffin Technologies has slider volume controls embedded in each mini jack, so each listener can adjust volume individually. Retail price is about $15 US.
7/10/2006: In HeadRoom's Show Us Your Sanctuary Contest, entrants submit a written description (200 words or less) and/or picture of their "Ultimate Headphone Sanctuary." The winner gets a free headphone system comprising a HeadRoom Total BitHead amplifier, Ultimate Ears SuperFi 5 earphones and a HeadRoom GigaBag ($500 value). Contest goes through July 2006. More info here.
6/29/2006: New Project: A Simple Tube/Opamp Hybrid Amplifier by Alex Cavalli, Mark Lovell and Bill Pasculle.
6/28/2006: Amazon.com is having a headphone clearance sale. Some great deals here such as the Altec Lansing iM716 for $79.97 (MSRP is $200). While supplies last.
6/28/2006: Grado is now shipping the GS1000, their new flagship model headphone. Like the RS-1 and RS-2, the GS1000 earcups are made of mahogany, but larger, and with larger circumaural ear cushions. The transducers are rumored to be larger as well and matched to within 0.05dB. All wiring (including the 9-foot Y-shaped headphone cord) is premium quality. Basically, everything about the GS1000 is super-sized. MSRP: $995.
6/20/2006: The latest product from Boostaroo, known for its line of inexpensive headphone amps, is the Revolution amp for portable players. Marketed to the audiophile community, the Revolution seems to contain some kind of 3-band expander circuit that operates on compressed audio signals to increase dynamic range up to 400%. The circuit also generates a surround effect. The Revolution can drive two headphones simultaneously. It measures 4.3" x 0.875" x 0.832", weighs 6 oz. with two AAAA batteries (22 hours), and comes in white with cables. MSRP is $60 US.
6/20/2006: Bose will be releasing a new version of their noise cancellation headphones later this month. The QuietComfort 3 is smaller (7 3/8" H x 5 1/4" W)and lighter (5.6oz) than the QuietComfort 2 and has supra-aural (on ear) cushions, not circumaural. Bose claims that that there is no compromise in the noise reduction performance of the QC3, despite the smaller non-sealing ear cushions. Part of the reason for that may be the memory foam material used in the QC3 cushions, which readily conforms to different ear shapes. The built-in rechargeable LiIon battery is good for 20 hours per charge. The QC3 can work as a cellphone headset with the optional Cell Connect accessory kit. MSRP: $349. Note: the QuietComfort 2 will remain in production at $299 MSRP.
6/16/2006: Unlike their previous surround products, which used their own proprietary technologies, Creative Labs has adopted Dolby Headphone for the new HQ-2300D surround headphones. The headphones plug into a palm-sized, electronics pack that houses the Dolbly Headphone circuitry and decoders for Dolby Digital and DTS soundtracks and Dolby ProLogic II for upconverting stereo sources into surround. The DH room simulation appears to be fixed, and there is no information about this feature. There are two standard 3.5mm jacks for headphones (users can plug in their own headphones) and jacks for digital/analog inputs (SP/DIF and optical). Creative is targeting this product for playback of movies, music and especially games. Two AA batteries will power the electronics pack for up to 10 hours. Retail price is about $100 US. At this writing, the HQ-2300D seems to be sold primarily outside the US.
6/14/2006: JVC put Dolby Headphone technology into a handheld adapter, the SU-DH1. The SU-DH1 produces surround imaging in stereo headphones from stereo and multi-channel recordings such as movie DVDs and music CDs. It can decode several multi-channel formats: Dolby Digital, DTS, Dolby Digital Surround EX, DTS-ES and MPEG-2 AAC, and it uses Dolby Pro Logic II to process stereo sources into 5.1-channel surround. Dolby Headphone can simulate three user-selectable listening "environments:" DH1, DH2 and DH3 - DH3 being the largest (concert hall simulation). Input is via two digital ports (SP/DIF and optical) and one stereo analog 3.5mm stereo jack. A single headphone output jack is mounted on the right side of the unit. The SU-DH1 runs on two AA batteries, weighs 3.5 oz. and measures about 3.5" square. MSRP is $130 US.

The system will respond to voice commands for cellphone operation and features an embedded sensor that automatically adjusts volume levels according to driving speed and ambient noise. A quick-release clamp detaches the headset for recharging. Each charge lasts for 7 Hours Talk-Time. MSRP: $150 US.
3/27/2006: AKG has dropped the price of the HEARO Player SE, its IVA surround processor plugin for Windows Media Player. It's FREE!! Download it here. Highly recommended.
3/25/2006: The Vincent Audio KHV-1 is a hybrid vacuum tube/solid state headphone amplifier with line level and USB inputs. The amp is rated for 400mW into 300 Ohms or 1.75 Watt into 32 ohms, suggesting maximum output characteristics of about 10V and 0.23A. The spec also suggests that the two 12AX7B tubes are installed in the front end and the solid state circuitry makes up the output stage. Two headphone jacks on the front panel and a set of line level RCA output jacks on the rear mean that the amp will drive two headphones and alternatively can be used as a preamp (extra switching facilities may be necessary). No published details about the internal DAC or the "class A" backend circuitry. The KHV-1 measures 6.2" W x 10.4" H x 8.2" D. MSRP: $795 US.
3/21/2006: TangentSoft has released pc boards for the PINT ("PIMETA Is Now Tiny") headphone amplifier. Each board costs $5 US. See the PINT page for more info.
3/21/2006: The Stax SRS-4040 II replaces the SRS-4040 electrostatic headphone system. The SR-404 electrostatic headphones in the 4040II appear to be the same ones in the 4040. The amplifier in the new system is designated the SRM-006tII. Compared to the old SRM-006t, the 006tII has a wider frequency response, a low-ripple DC tube heater supply for lower noise, 3 inputs (2 sets of RCA jacks and 1 set of XLR) selectable by 3 small buttons on the front panel and two high-bias "Pro" headphone outputs. The standard bias ("Normal") output has been removed. Pricing: $1800 for the SRS-4040II Signature system and $1500 for the SRM-006tII amplifier alone.

The internal class D amplifiers run off 6 D-cell batteries or an AC adapter. MSRP: $349.
2/22/2006: HeadWize is featured in this month's issue of RedHat Magazine.
2/22/2006: C-Pads from Headphile are earpad replacements for Grado headphones. The earpads themselves are circumaural types from Beyerdynamic, for headphones larger than the Grados. Headphile has created an adapter plate that snaps onto Grado earcups (easily removable). The Beyer pads then slip over the adapter. If the bass response is too strong, users can remove pegs in the adapter plate to vent the bass. These replacement pads will fit all Grado models, including the Alessandro-Grados. The Z-bowl model holds the tranducers closer to the ears than the Z-flat. Available in a variety of woods and custom port configurations. Prices start at $99.
2/2/2006: The Sony MDR-DS6000 is the newest model in Sony's DS headphone line and the first to feature 2.4GHz digital RF tranmission (the other models use infrared). The transmitter/base has a range of about 30m and provides optical and RCA-type input jacks. There are decoding options for Dolby Digital, Dolby ProLogic II, MPEG-2 AAC and DTS. It can also transmit 16-bit audio CD streams without compression. All DS headphone systems include an audio virtualizer that simulates 5.1 surround imaging in the stereo headphones. The full-size closed-back headphones will run for about 7 hours on two alkaline or rechargeable NiMH AAA batteries. NiMH batteries will recharge if the headphones are stored in the base.

1/10/2006 Commentary: Apple's new remote control for the iPod uses FM-encoded signals. IMHO, they should have used Bluetooth digital encoding, and the main reasons for not using Bluetooth must be cost and circuit size. Bluetooth is the more versatile and higher performance solution and could have given iPod users freedom from wired headphones. Still, this product is perhaps testing waters. If it turns out to be successful, Apple may later offer an iPod with Bluetooth support.
