My first headhunter arrived for my B day flooded before i reached 10 feet in depth sent it back and argued eventually received it repaired, second time I used it , it flooded 1 minute off the boat in a few feet of water, sent it back, was returned via dhl, when the box came it was busted so I opened it on DHL counter for insurance but the joke was on me as water came out the ear cups, so much for pressure testing of course I gave up as it was the worst service and it gathers dust under a counter, dont recommend them this was 3 years ago and money was hard to come by what a waste.Personally I suggest you save for a new unit, not another one of these, poor service, poor ear cups. Cheers
