MM 550 ... just what I was looking for1/13/2013
I was looking for a quality product instead of those expensive headphones that sell b/c of their brand name. This was it. It had all the features I desired somehow fit into a reasonably sized headphone: bluetooth (with optional wire), SRS, talkthrough feature, and noise-cancelling technology. They twist, fold fairly compact and have a bag to travel. The only downside noted, as of now, is that it'd been nice to have a fitted case to provide more protection. Otherwise, very happy!
