Charged them up and then tested them. After using behind the head headsets for 3 years the first thing I noticed is I had forgotten what bass sounds like. Not a serious audiophile use them mostly to watch movies late at night. Like the easy volume control. Quick start guide did not tell you to hold down the power button until it went in pairing mode but I knew that is what had to be done. Paired easily to my laptop. Like other commentators I did not receive the cord that should have been included to enable use with wired systems. Other than not receiving the cord that should have been provide no other complaints at this time. Tested them with Skype and was told my voice sounded good. Much better than the last behind the head set I paid a lot more money than I did with this pair. Don't hear the hiss other people have complained about. Not sure who to complain to try to get the wired cord I was promised. Over all better than what I expected for the price I paid.
