In general, the sound is good and clear. Subtracting the cost of 15 into consideration when evaluating a, I would say even very good. The volume can be turn up well. The bass is enough for my circumstances. On the bus, you can take calls without hesitation, it is well understood, despite noise. You can use it after a few days use completely blind. We paired it with the iPhone by pressing the answer button (center) until the LED turns red and blue lights. Only then it can be found from the phone. Running the headset is tight and does not interfere.
