Those gripes notwithstanding, surround-sound quality on movies was nearly indistinguishable from normal (wired) sound. We say "nearly" because the bass from our Dynaudio Contour 1.1 speakers sounded somewhat thin, and the treble had a harsh edge. But these shortfalls were slight, and we were listening attentively for differences. Less critical listeners--the same vast majority who can't tell the difference between MP3 and CD sound quality--will be quite satisfied with the Rocketfish Universal Wireless Rear Speaker Kit's performance.
Two final notes for HTIB owners considering this product. First, double-check that your system uses traditional bare wire ends for connecting surround speakers--newer HTIBs that utilize proprietary plugs (usually color-coded) won't fit the Rocketfish. Second, it's worth double-checking whether your system manufacturer makes its own wireless system. If it was purchased after 2006 or so, it's a fair bet that it does. Not only will the companion wireless kit offer guaranteed compatibility (even with those proprietary connectors), it may well cost less than the Rocketfish. For example, the Samsung HT-X70 would work fine with the Rocketfish--but you can get the similar Samsung SWA-3000 for a few bucks less.
The $100 Rocketfish can't compete with the best-in-class KEF Universal Wireless Kit--and given that the KEF costs six times as much, we wouldn't expect it to. Rather, the Rocket Fish Universal Wireless Rear Speaker Kit is worth consideration for casual listeners who want to cut those long speaker cords--so long as they don't mind a few relatively minor compromises.
