Tom’s Hardware Guide review of Zalman’s new ZM-RS6F headphones, which are the first to offer true 5.1-channel surround sound (other surround sound headphones, like the ones from JVC we mentioned last year, only simulate 5.1-channel sound). The get true surround sound, the ZM-RS6F actually has six transducers, or speakers, in it so that all six audio channels can be properly reproduced. The downside is that you need to have a sound system or a PC sound card with front, rear, and center audio jacks, something that your average portable DVD player, which typically only has a regular old two-channel stereo headphone jack, doesn’t usually have.
