I'll second cudamark. I just ordered a set of Tony Eisenhower custom headphones. He's making me a set of Blue headphones, which has cups that are wider/bigger than his white phones. The Blue phones have better noise attenuation, so better to hear those faint "Whisper" signals. He's also adding his enhanced impedance matching circuitry which boosts the volume. I wanted to combine quieter phones with louder volume. I also selected his Divers version, same as the Waders version, he just adds a few drain holes to allow water to drain more quickly & thoroughly.
And those "off the shelf" phones can be very expensive for the lesser quality you'll probably receive. I saw Minelab's waterproof phones selling for $170. For less than the price of a Starbuck's coffee's price difference, you can get a set of Tony's hand-make headphones, which all reports have indicated are super comfortable. Even Gigmaster did a comparison of Tony's white phones to Minelab's waterproof phones, said that the Minelab phone headband hurt the top of his head after a while, but with Tony's phones, they were so comfortable that he could wear them all day, and wouldn't shake off the head.
Tony doesn't have a website, only works via email, so if you'd like to get a faster reply, email him and in the subject line put: "Tony, Sand Swinger from the TreasureNet forum sent me". He'll know that you're a referral from a customer and not just any guy emailing to take up his time. I don't make anything for referring his phones, just like helping out a guy who's making a great product. Here's his email:
