This was not disclosed and as such, entirely NEW drives and a NEW enclosure must be purchased to replace this unit which is ALREADY IN SERVICE. Awesome gaming headset for people who dont want to spend alot. Detail:Ive historically used Sony Headphones (Im a fan of Sony) at the $50 - $60 price point and these headphones @ full retail sit at the same price point. Ill update my review when I get the solution. I tightened the bolts up on each leg to create more friction so they stay open even better when putting the bike into the stand. After years of just managing with the cord that came with my phone I was pleased with the flexibility that I have with the longer length. I thought at first that he had the headphones maxed out. thats why I say they may run just a tad wide. Lo use para reemplazar el encendedor y fue muy fácil instalarlo, use los mismos cables del encendedor para conectar el cargador, una buena forma de conectar el cable usb y no tener problemas con los conectores que luego se botan o no cargan lo suficiente Oh, and it would be fabulous if one could purchase 2 of these at a discount? But that would be just too perfect wouldn?t it!
