Joggers, snowboarders, and other outdoor enthusiasts will delight in the Sony MDR-J20 headphones, as their contoured clips follow the curve of the ears to ensure a snug fit even when bouncing around. The headphones also feature a flexible ear hanger that reduces stress on the ear, along with an open-air design that lets in ambient sound without sacrificing the quality of the music. The latter function is particularly important when skateboarding or running, as users can listen for traffic noise and other audible threats. lt's the audio, however, that matters to most listeners, and the MDR-J20 headphones deliver on that count, too. Each earpiece carries a powerful neodymium magnet that provides great sound at frequencies between 18 Hz and 22 kHz. Don't give in to poorly designed, bulky headphones that slow you down while exercising. The MDR-J20s, which weigh a mere 0.35 ounces, are a perfect fit.

Buyer's feedback: - * Not recommended ...
The sound from these headphones is decent but the cords tend to tangle. Also, after a few months the plastic that covers the wires started ripping and the wires became exposed. I highly recommend that you do not buy these.

Buyer's feedback: - Not as good as the MDR-J10
I bought these headphones today and I am really dissapointed by them. I used to own the MDR-J10's and really enjoyed using them while I exercised. I lost those and replaced them with these, only to find out that they are don't work for me quite as well. The clip is not very stiff and only causes the phones to bounce around much more than the MDR-J10. Also the peice that you put into your ear is bigger than the J10s and doesn't stay in or on my ear at all. Remember everybodies ear is different, so maybe they will work for you but beware.

Buyer's feedback: - * Don't Buy!!! ...
I bought these headphones and in the beginning they were great except the cords were very tangle prone. Well after less than 3 months the black rubbery material that covers the wires just tore and exposed the wires. Then they started making a weird noise and I called Sony because they are still under warranty, but they don't want to honor the warranty and they want me to either pay $16 for refurbished ones or possibly $58 to fix them. Yeah right on both accounts.

Buyer's feedback: - * Sony MDR-J20 ...
I purchased the MDR-J20's to replace my iPod headphones during my workouts. The MDR-J20's are comfortable enough, however the sound is not nearly as good as the iPod headphones. The sound wasn't as rich as the iPod's. When I played some jazz music, the sounds was OK for my workouts but when I played my up-tempo workout music, the sound hurt my ears after just a couple of minutes. I can not recommend these headphones.
