Good sound quality, but may become annoying after a few hours.

Excerpt: This headset works really well for the price you are paying. It gives suprior sound quality compared to other headsets. You can hear everything crystal clear, and it has a good volume level. You are getting your money's worth. I have found a few issues with the headset for certain people. People who have ear problems could have some issues with this headset. After a few hours of constant wear it does begin to hurt the inner ear because of the way it sits in your ear.
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. The sound quality, IMO, is similar to the JVC HAFX33 Marshmallows--good for all of the bad reasons, but it's not necessarily a bad thing. The sound is above tolerable, especially in the bass region, in that the bass seems well-extended and nicely punchy at all times.
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. The highs have some distortion (hard to discover but there). On the other hand they are very loud headphones even louder than the newer ex 81's. They are optimized for portable devices.
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. I use the MDR-EX51's (same model without the extension cord) with my iPod.
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. To make sure that I am right try to listen to the bell ring or human speech, oh yes violin on those earphones.
