My first set of wireless Bluetooth headphones. Sound is very good and the Bluetooth connect ability is good. Loudness is ok, you can't blow your eardrums out with these. I don't use the mouth piece so can't review. They fold up for storage (would have liked a drawstring bag for the price paid). Wouldn't connect to my old MacBook even trying the included USB device included with the headphones. Works with my iPhone, pad and pod. With extended use, the on the ear pad becomes uncomfortable to the point you are forced to remove them and message your ear (over 1-1/2 to 2 hours).
I had trouble syncing the headset to the computer as the computer didn't originally discover the device. However, was able to finally sync it when using the troubleshooting instructions. Did loose sync once and had to redo the process.
Bottom Line Yes, I would recommend this to a friend
