Bluetooth does not work

Definitely does not block out any surrounding noise, but for the price can't complain.

The only thing is that it does have a tiny bit of to much bass which you can't adjust, but not enough to bother me

The microphone does not work well outdoors with any wind

Really good product for its price, does feel a bit uncomfortable if you wear glasses, and the sound could be a bit better but for its price it is great for regular wearing!

Lastly, the sound does leak out from these a bit but, no more than any over-ear earphones would
