Pros Great Sound, Good Fit, Comfortable, Wonderful
Cons NONE, NUNCA, NADA, NIP
Summary I have had these headphones for 2 years now, ever since i got my iPod, i went to circut city and bought them, they have gone through 2 years, but now they have to be retired. These headphones deliver real, rich, blow me away sound! I turn them up full blast (you don't need to, trust me) and hurt my ear drums (i like it), and the sound is the same amazing quality than a comfortable volume like mid-bar. So GET THESE!!! EVERYONE! They're awesome.
Pros cheap and look alright
Cons shock ear, fall off easily
Summary shocks ear and are not comfortable to wear, fall off of ear easily
Pros Great sound and for me, a great fit.
Cons A case or some way to store them would be nice.
Summary I did it backwards. I bought these then decided to up grade to the MDR EX81's which cost more than twice as much. What a mistake. I can only speak for myself but the J20's fit me much better than the EX81's and the sound ... no comparison. With the EX81's connected, I set my MP3 player to a comfortable listening level, 18. I unplugged them and plugged in the J20's and got blown away. I had to turn the level down to 12. Much fuller sound, much louder, more comfortable fit, AND less than 1/2 the price. What's there to think about? For $20 you can't go wrong.
