Good sound for the price.

Not so much waterproof. When the earphones get wet (sweat), bass response is nonexistant.

These are great headphones as long as you do not get them wet. If I run for more than 5 miles, sweat seriously impacts their sound quality. When they are dry, sound quality is decent. To me, cheaper Sony products have better sound quality. On form/functionality nothing beats them. Would score them higher if they were actually waterproof.

Excellent sound... increadible bass! Very comfortable to wear; great behind-the-neck design - stay on better than individual ear buds.

I blew the speaker the in the right ear too easily. During a hard workout, sweat will enter the speakers and cause them to produce only treble.

Make them waterproof and more resistant to popping due to bass!

Sounds great, excellent frequency response

Only one size, and it's not adjustable. Because I have a rather small build, it tends to stick out too far behind my neck.

I would definitely recommend these headphones. They're waterproof and stay on.
