"I am a big fan of the Oakley Thump. I had the originals but these were quite fragile and the lenses tended to brake off so when the replacement lenses became unavailable I upgraded to the Oakley Split Thump. As I use them when cycling it is a great bonus that the Split Thump is sweatproof. The earbuds don't have to be pushed all the way into the ear so you can still hear your training buddies and all traffic noise. The reason for not giving 5 stars - the removable earbuds must be pushed into a micro usb like port - looks a little fragile. Would have been better to push them into a headphone jack style hole instead."
