Battery life is extremely good. I didn't get a chance to flat it out yet. I charged it once after I received it. Already have watched 5-6 movies.
Sound is pretty clear but not very loud. I cannot compare it with any other Bluetooth headset, cause I never had any. If I had to compare, I'd say it's as good as a standard wired Samsung earphones.
Bluetooth range is good. Didn't face any issue in my brick built house, no issue at all from one room to another in my 100 sqm house. But, if leave my phone in the car, can't listen to even 5 metres away. It's may be because of the metal shield. In the open field, it can reach more than 20 metres.
Call quality is good. My wife couldn't say I was using a Bluetooth. She didn't mention about any noise. So it's good I think. When l listen to music, can't hear anything else. If not, can hear everything. So, it's okay for me. So, I'll give 5 star to noise cancelling as well.
Didn't notice any latency or sound leg. I can safely say, it's a good buy.
Only wish if the sound could be louder. I use 100% of its capacity.
