Perfect Sports Buds I bought these headphones after trying a few other designs from Sony as well as other companies. My day to day headphones are the Sony MDR-EX75 earbuds, which I LOVE, so I was looking for something similar in a waterproof package (I shorted out a couple pairs of the EX75s while working out). These were EXACTLY what I was looking for. Same great sound, comfort, etc. All in a package that was waterproof and stayed on my ears (better than Sony MDR-AS20J Sport Headphones). So far I'm convinced about 10 of my friends to get the same earbuds and they ALL can't work out without them now! You can find them cheaper on some other websites! ($25) June 10, 2009
cord way too short to be useful I got this product in Japan, in the Sony shop in Ginza. In the package there was no extension cord, so I had to do with te 2 ft cord. I'm 180cm (5f11') and It's simply way too short. I can't have it on any device if I am in the Gym or running. It may even have a good sound, but I cannot exercise. Maybe good only with an Ipod nano clipped on your neck ... December 23, 2012
Love Them but they break this was my 3rd set. I love them but will not keep buying them. This last set lasted less than 3 months before the sound stopped coming from the right ear piece. None have lasted past 10 months. December 14, 2012
Best Headphones I have ever had I spent about $800 looking for a decent sound quality headphone that would stay on me while running regardless of speed. I finally purchased this pair and I wont look at anything else. They have been washed and dried with my clothes, several times, and I have not had any problems in the three years that I have had these. I have a background in studio audio recording, and I have yet to find a better audio quality then these. I run with them often, never fall off. They are comfortable, stylish, nearly impossible to break. October 5, 2012
