Slick, comfortable, and awesome quality, the AC-404 analog stereo headset is a great choice for anyone doing Voice Over IP and gaming. Bring your ears to attention with the AC-404's 40mm dynamic drivers. The adjustable, over the head design fits comfortably on any head size, and the flexible, noise-canceling boom mic's 180-degree rotation gets the job done, no matter your preference. Comfort is no issue with the AC-404's soft velvet ear pads, and with in-line volume control, adjustment is easy. The AC-404 includes a 4 barrel, 3.5m plug which works with the iPhone/iPad and any tablet or newer notebook/netbook. Additionally we include a Y adapter in the package so its backward compatible, meaning, the headset will then work with older notebooks or PC's that have a 2 plug connection.
