I bought this product a couple weeks back and I ant be happier!!!

Asked for them for the gym but the sound off them was so quiet I went back to earbuds. ok for talking to people on calls but poor for music. I'd suggest over the ear headphones with a bluetooth receiver. Works a treat for my mdr-100.

I am trying to like the headset. the fit is excellent and easily connects to my sony walkman. When you get the correct size arc and bud combination they sound great. It's the max volume that is the sticking point. you will always have the volume at max on these headphones. For the most part its loud enough, but a lot of albums can be lower in sound and then you find the problem when you cant turn up the volume because you will already have it at full volume.
