Overall, the sound and ergonomics is good, but the charging a pairing process is annoying.pros:- comfortable to wear- decent weight- good quality sound and very decent bass- the BT range is a little better than my last BT headphonescons:- very difficult pairing and turning on process. I have a mac which typically makes bluetooth seamless. however, instead of an on/off button, Moto makes you hold down a power button until you see two blue blinks. the blinking happens in a light which is under your finger when you're pressing the button so you can't see it. after doing that apparently you also have to hold down the other start/stop button for about 3 seconds. at some point the mac will pop up with a dialog asking if you want to use the headphones. if you do that at the right time relative to the other button presses on the headphones, you might actually hear sound coming out of them. this is very tedious - all BT devices are somewhat clumsy in my experience, but this one is worse that usual. A simple on/off switch for these headphones would be a great improvement.- the charging is via a USB cable. this isn't too bad, but it is much more difficult than some of the advanced wireless headphones which use a cradle charging system where you can just set the headphones on the cradle and they auto-charge.I got a pair from a 3rd party for about $45, which was probably worth it - but these aren't worth more until Moto fixes the pairing/turning-on issue to be much simpler.note: I do not use the microphone, and I am pairing this with a desktop to use as headphones only.
