This is the first bluetooth I've owned. I bought one for my wife a couple months ago and found it had good sound quality and excellent range. This review is for the one I bought for myself. It still has good sound quality however range must depend on the phone, her Sony z520a will go anwhere in the house (don't buy the z520 it's still a crappy phone). My Sony w600i only has a range of 15 feet or so.Regardless, this is a great bluetooth and we're sorry we waited so long to get one. (or two...)
