I got these headphones for my husband because neither of us like those nasty little earbuds that stick in your ear (too much like hearing aids) and he really loves them. They don't hurt his ears and they don't get sweaty and nasty when he's exercising.

I bought this headphone set because of the reviews that said it was great for the gym. The sound is very good and they fold easily to fit in my pocket or bag. However, if you are working out and bend over - you're going to be picking this 'puppy' up off of the floor! The headphones are very comfortable, but not nearly snug enough to stay securely on your head. (And I don't have a real small head) This is the only reason that I rated it at 4 stars - certainly not because of the sound quality. I can use them around the house or for walking, but I had to buy another set for the gym.

These headphones put out too much treble in relation to the bass. The sound is not balanced. To make it worse, the treble that it does put out gives the sound a rough quality. They may be compact and convenient, but they're not for someone with a good ear.

This is very conventient and has great sound. It folds up perfectly to put in the DVD case. Just what I wanted

These Sonys are possibly the worst quality headphones I have ever purchased in the $20 to $25 price range. You can't hear any bass and they distort at a relatively low volume. I give them 2 stars for the foldable design.
