Product Description

These are difficult IEMs to get right. It took months and tip experimentation but, if they fit your ears, when dialed in they work magic. My Klipsch Custom 2 or HiFi Man Re-0 for example don't come close. Even the Etymotic ER-4s are just in the running.
Position and tip fit are critical. Properly worn the IEM's body is almost straight vertical with the round end down and tip angled slightly forward into the ear canal, cables over the ear. When I wear them they're almost completely hidden viewed from straight on. As with all IEMs, experiment around a constant sound source like a fridge or fan until you maximize the attenuation of external sounds. At their best, isolation judged against foam earplugs seems to be in the ~25 dB range.
The supplied tips are junk. The only tip that properly seals in my ear are Sony hybrids. PROPERLY WORN, while not bloated 'bass head' phones by any definition, sine waves are clean, solid and even to below 30 Hz. Bass is wonderfully detailed and balanced on naturally recorded musical instruments, lacking only the deepest registers on effects like thunder or fireworks. That spectacular detail continues up throughout the frequency range. In my ear tones suggest a mild emphasis around 3 kHz. Highs are clean and extended. Those expecting the 'warm' AM radio balance of some comparably priced units, for example the Klipsch Custom 2, won't take a shine to the AT. I've used the ATH to set up radio stations and studios, it's simply leagues more accurate.
The cable is soft and very low in microphonics. In my ear the snug fit is all-night comfortable. I gave up on my ATH-CK9s and they sat around unused for months until new tips purchased for different phones prompted yet another listen. Glad I did. For the price these are a stone steel, my fave out of nearly a dozen IEMs, and likely to thrill anyone willing to put the time into achieving its spectacularly natural and detailed potential.

Personal Opinion about this product,January 29, 2010
First, I have to say that I tell everything as personal opinions and feelings. I don't exaggerate things to persuading people to buy things.
I play violin for more than twelve years now. I am super picky to the sound and music systems around me. I personally own [Bose QC2] and the [Bose in-ear headphone]. I use [Bose Companion 5] speaker as my sound system. I really have to say that if you have enough budgets, Bose has the products that will not let you down.
I have speakers from Creative, Logitech, Altec Lansing, and Bose. And I have different opinions about each of them, but I won't talk about them here.
I bought four different headphones recently for fun to see the difference from different brands (Altec Lansing UHP606, Audio Technica ATH-CK9, Altec Lansing Black Beat PRO, and Able Planet Harmony Active Noise-Canceling Headset). I bought the ATH-CK9 ($249.99, I bought it for $94) by Audio Technica in December 2009. I think this product is good at high range sound. Although, comparing to the [Bose in-ear headphone] I had, the [Bose in-ear headphone] is a lot comfortable and a lot stronger in Bass than the ATH-CK9. So far, [Bose] is the only brand that I have tried with "enough" bass. I always get disappointed whenever my friend lends me his headphone which he told me that it has a strong bass. I am not satisfied with ANY other in-ear headphones (especially the ones that marked with "strong bass").
In the last words I will say, this ATH-CK9 headphone by Audis Technica is worth buying if it is less than $70 (Compare to the price and value of $100 Bose in-ear headphone).
