Purchased on the basis of generally positive tests and testimonials. The product is not bad, but I'd advise against Apple users: with my MacBook Air, it constantly cut (less than a meter away!), And it's not really that either with the iPhone and iPad. So I've pretty much given up to use it. On the other hand, the only downloadable firmware is an .exe, so for Windows. No Apple support ... I put 2 stars, because it may have qualities, but they are not really accessible to me. My wife has a BT Sennheiser raises him far fewer problems. In short, buying for design ...
