DV Hardware have a short review of the Sennheiser PMX70 Sport earphones.
Right now, Sennheiser has got the PMX70 Sport headphones which are currently being sold for =A330. These are gym headphones which just fit anybody's head just right. Yes, it does not matter if you have a huge head or a small one. They just fit snugly on and around your neck's back without being uncomfortable at that. You would find the speakers to be snuggled just right in your ear..Sennheiser PMX 70 Review
