Sennheiser PMX 70 Sport

Pros: The sound is pretty good for a sport headphone

Cons: lots of pressure on the ears, and the wires are to small so there is a lot of static after a few days

Summary: The wire is real small, and only a few days after using them I started to get a lot of static. I researched it on a few retail websites and a lot of customers were having the same problem. I would not buy these again.
They are a one size fits all deal. My head is not huge but the pressure really startes to hurt after about 20 minutes. I have to take them off if I ware them for more then 45 minutes.
If you have a smaller head and the wireing issue dosent happen with your pair then they would be great headphones unfotunantly I had a problem and that is why I gave it a 3 if it had only happend to me I would have rated them higher, but after doing a little research its not an isolated case. That said you should think about it before you make the purchase.
