... I'm not a gadget expert when it comes to smart phones, neither am I a self-proclaimed audiophile, but I do have a good understanding and sense for design, and do know a bit about technology... this piece was extremely easy to set up -- came precharged, and I could connect it to my Samsung Galaxy Note in less than 20 seconds.. turn on bluetooth, press the power button, search for it, connect, done. Plus, the range is excellent. I cannot agree with reviews I have read here that were arguing about range issues.. you have to keep in mind that there are two components to any range issue.. the sender (mostly your phone, in this mostly passive system), and the receiver. If you have range issues, I would first look into replacing your phone tbh.. I can wear this headset in another room (and my rooms are quite big, i.e. more than 6 meters!) I think it is about 4.5 stars, I give a bit of a minus on the audio quality (I said I am not an audiophile, but the quality could be a bit better, the bases sound too flat, but overall it's a compromise I am willing to make, it does not sound bad at all, just not the same audio quality you'd have with a regular headset, particularly not with a noise cancellation headset that on average have better bases due to the nature of how noise cancellation works).. As I will use it for running, noise cancellation is actually not what I want, I like the fact I can still hear the honk of a car etc (unless I turn up the volume all the way)... If the product should not hold up to it over the next couple of weeks/months, I will come back and edit my review..
