WOW!!!! These are really good headphones. I have several pair of Bluetooth headphones and so far these are the most comfortable, lightest, and best sounding one that I own. Set up and connection was simple, and Bluetooth range is great. But the sound quality on these is way better then I would have ever expected at this price point. Very crisp and clear vocals and bass that is beyond what you would expect from headphones at this price. I have not used them for making phone call yet, so I cannot speak to the quality of that, but for listening to music while running, working out, or just relaxing, I would highly recommend these headphones.
