Audio Technica ATH-CKM50A In-Ear Headphones

Bought on a whim to replace the standard iPod in-ear buds. I was looking for something that provided great sound with comfort... success! They fit snug with zero pain and include three other buds for a perfect fit. Included extension cord is a plus.

While theses are not the most comfortable earbuds I have ever had they are the best sounding. They are also very snug fitting which is great during activity so I don't have to keep adujsting or putting them back in. As long as they fit in your ear you will not be disappointed with these.

The headphones sound very nice, and I prefer my in-ear phones to have less high-frequency sound than my on-the-ear phones (Koss Porta-Pro). Too much treble and I get fatigued quickly. Upper end detail is fine and I can hear Paul's bass clearly on my remastered Beatles' CDs. Therefore, I will probably keep them for use with my Blackberry and my Sansa Clip.

The fit, however, is not great. I had to buy Comply foam tips in order for them to stay in my ear when I work at my desk. They probably would not stay in my (admittedly narrow) ear canals while working outside or working out at the gym- which was a disappointment. On balance, though, some folks will like the fit, and their sound is conducive to listening for extended periods of time. If I payed list price and had to add the cost of the Complys, I might feel differently, but with Amazon's discounts I feel I got good value. I'm a happy camper.
