Summary: I had these earbuds way before I started collecting some good-end gear, boought them about two years ago. I found these emptying my closet, and I figured I would give them a shot two years later.
Summary: I personaly expected a lot more out of the sony ex71's, especially after so many people love them. The bottom end (bass) dominates the sound and is annoying giving you a headache, after a while. The bass is boomy and the mids are covered and underexpressed.
Summary: If you're a portable music listener and you love bass from earbud/canal headphones, these are perfect. I use these headphones everyday at work connected to my PC to listen to MP3's. While the overall quality of sound isn't what you get from full-size cans, you get more than what you paid for at $25.
Summary: I bought those earphones mainly to use them in gym. In the first time, Sony MDR-EX71 was quite impressive – powerful bass and clear mids. Especially it was good in reproducing the sound of guitars and cymbals. But later on I found out that the overall sound was harsh, and highs were inferior.
Summary: Seems like a very ubiquitous unit for the ipod set, especially in the subways of NYC. I still use these for cycling because of the short cord to my shuffle on the arm but I have a lot of gripes and quibbles. 1.) Not very durable.
Summary: These are great little canal phones, and they're fantastic value. They isolate a little, but not as much as the more expensive canal phone. This makes them more approriate for some situations, but not appropriate for air travel or noisy environments.
