Etycom Headset Pillow Pak Review

Due to my line of work, I probably spend 25 hours a week with a headset strapped to my ear. I have tried Plantronics, Nokia, Ericsson, plus a few off-brand models over the years. Etymotic Research makes what are considered to be the Rolls Royce of ear-bud headsets; so when I saw the Ety-Com set on the AAUG review table, I had to give them a try.
As with the isolator line of ear-buds, the Ety-Com's single bud fits into the ear canal. From there, a bendable metal boom, capped with the mic, extends to about mid-cheek. A cord runs from the bud to a 2.5 'micro-mini' stereo plug. This plug is standard for many cell phones and some cordless phone handsets. There is also a built-in clip to secure the cord to your shirt.
When fitting the Ety-Com, I found the best sized ear tip, and followed the instructions for insertion (pre-moisten ear tip, and tug up and back on your ear while inserting - takes two hands).
I tested the Ety-Com with my Sony Ericsson cell phone in a variety of conditions and with a V-Tech cordless telephone at home. I found the sound quality to be clearer than any headset I have ever tried. The sound baffles in the ear tip do a wonderful job of blocking out unwanted outside noise. The end result is that a lower volume level can be used for the call. The clarity was so good, in fact, that I could detect audio artifacts in my cell phone that had gone unnoticed to date. I asked friends and family how I sounded with the Ety-Com, and got favorable responses in all but one instance. The mic did not do too well with the wind noise of an open car window. Although the microphone housing on the end of the boom has two offset sound holes, I'm not sure that this is a truly noise canceling mic. I found this headset to be extremely comfortable. Etymotic has really done their homework on the ear tip design! The only problem I found is that the boom sometimes wants to fall under it's own weight. With other over-the-ear headsets, there is more support to keep the boom from moving. With the Etymotic, the ear gel is the only point-of-contact with your head. When gravity tugs the boom down, the attached ear bud rotates. A work-around is to initially insert the ear tip with the boom higher than needed, then allow it to settle in place. The boom can be reshaped as needed. Use of the supplied shirt clip also helps to mitigate ear bud movement.
I did not try the Ety-Com at work due to an incompatibility with my telephone's Plantronics phone cord. I did find some online sources selling adaptors for $30-40 but have not yet ordered. Also, the Ety-Com is not compatible with my Powerbook for internet chat use. Although it may work by using a 2.5mm female to dual 3.5mm adaptor and a Griffin iMic. I have had some complaints about sound quality using a Bluetooth headset, so I might adapt the Ety-Com for use with iChat or Skype.
Included: Ety-Com headset with 4' cord, shirt clip, four different sized ear tips, one spare filter and filter changing tool, carry case with inside mesh pocket, and documentation.

The Etymotic hf2 is a high-fidelity hands-free headset that is compatible with the Apple iPhone and other mobile phones. The hf2 earphones are the next best thing to live music, with noise isolation far surpassing that of active noise-canceling earphones. Their external noise exclusion allows you to hear the full dynamic range of recordings without having to play them at unnaturally high and unsafe levels.There is a built-in microphone in the middle of the headset. The microphone features a single button for answering and ending call.For music listening, press first click for music pauses, second click to skip to next track and third click to go back to previous track. With a regular 3.5mm stereo plug, it is compatible with most mobile phones and music players, also. With the response accuracy of a reference level earphones and the highest noise isolation of all competing headsets, this is the best Hands-Free headset period.Transducer type -Balanced armature Sensitivity (1 kHz) -105 dB SPL for a 0.1 VRMS input Impedance -16 Ohms (nominal) Maximum output -120 dB SPL Maximum continuous input -0.55 VRMS Microphone sensitivity --40 dB V/Pa Cable -4 feet Weight -1.3 oz hf2 headset + earphones exclude most external sounds. While driving, always leave one ear open. It is unsafe to use in-ear earphones while operating a motorized vehicle, operating machinery, bicycling or jogging, because you may not be alerted to potential danger.

iLuv Noise-Canceling Headphones with Bluetooth Wireless Technology (Black) Review

I've tried out several pairs of noise canceling headphones and bluetooth headsets, and this one does its job well both in noise canceling (comparable to $100 pairs by audiotechnica, except it is not circumaural) and in bluetooth pairing (clearly excels over the Motorola S9)
Its bluetooth setting take a little getting used to, but once you know that you do not need to re-pair the headphones even if you switch between audio sources and that the play/pause button actually serves as a bluetooth-reconnect button if you wander out of range, they are really very intuitive.
The headphone's microchip sports two audio-modes instead of two audio streams for its Advanced Audio Distribution Profile (HQ music) and Hands Free Profile (mobile)... This surprised me at first, but it actually allows you to have a lot of freedom.
Battery life is great with a 10+ hours of continuous music streaming (experimentally) and a mere 1.5 hour (also experimental) charge time.
I can't say enough good things about this product. Asides from the mentioned items it also has great sound quality, and the fold-up ability is pretty handy for mobility.
The only two things I would've liked for it is to not look so cheap and to have came with a carrying pouch that is its size (and not like 3X larger)
