I don't use phones, and these are a royal pain. TOO LOUD... I was playing with a Silver UMax I am going to sell, checking air distances to make sure it was working within range. At maximum output the phones are too loud. Backing off a bit, the volume goes to nothing.. I am not an electronics person, I even have someone redo my 110 V plug wires when required. So if $35. is about right, be my guest. Pay Pal fine, will be sent priority, insured. Thanks for looking
