It is a TRS / 3 pole cable so you should only use this with a regular stereo pair of headphones. Theyre not pretty, but theyre super comfortable. Its really the only thing I have to complain about it. I dont know what they are doing differently, but Yellow Box has lost a very loyal customer. My 3 y/o is a size 7 and they are a perfect for for her, even when using the heel strap. The mount also would not give a solid snap to keep the Bolt centered, so it was always threatening to twist off the mount. WRONG SIZE. As soon as I took the first one out the package to wear the clasp broke. The material is a lot thinner than expected and not as soft as expected. Anyone complaining they sound bad, are either using a cheap sound card or worse, on-board from a cheap motherboard.
