Sorry never used but did look up. One thing about beach headphones around water... in time there will be issues. Me, I make my own and If I were in the market to buy some I would go Tony Eisenhower, he's very good about warranty and repairing his older sets that are several years old. And he does offer a upgraded set with super large 65mm piezos which is the limit on how big you can go. The one common denominator that all Water proof production head phones have is Piezo's buzzers for the audio.Hello,
Anyone tried the Radioactive Brand Headphones from Brazil on the Manticore.
