These Sport Bluetooth Headphones by TeckNet® are just great. They are noise isolating. In the box you get the earphones, charging micro USB cable, and 3 sets of different sized ear buds and ear locks. They paired very easily and quickly with my Samsung S6 phone, my MP3 player, and my laptop. The sound quality is great. They can go very loud and it is very clear. The battery life seems to last really well. I wore them for about 2 hours last night and had them on several times over the last few days and they are not dead yet. They are very easy to work with. Just charge them up, pair them up, and you're ready to listen. They're very comfortable to wear. I work for a cleaning service and am in full motion all day. Regular wired earphones are a pain. always getting hung up on stuff and getting ripped out of my ears. If I buy cheap ones I am lucky if they last a day, but now I have these babies. I can do anything I need to do and nothing is getting hung up and nothing is being ripped out of my ears.
