Razer swung out a wide range of gaming hardware and accessories on Tuesday that included a few extras for Apple users. For everyone, the Tiamat 7.1 is billed as the first true 7.1-channel surround sound headset. By packing five drivers in each earpiece and coordinating their output, it can replicate not just the seven main satellite points but the subwoofer channel as well. Owners can individually adjust the output of each channel and revert to a regular stereo signal if they like.
