I've been using wireless speakers to expand my stereo system throughout my home since the 90's. The original pair, the Recoton 900Mhz were stunning and I initially bought a powerful Bluetooth transmitter and two Bluetooth speakers to replace them. This was a mistake because 1) the Bluetooth process causes an audible delay compared to wired and older wireless speakers, and 2) the transmitter interferes with other Bluetooth signals by causing interference. I was happy to find the Wolverine system, one of the few non-Bluetooth wireless systems I could find. This system costs $70 and is a steal compared to my previous wireless systems. Compared to other wireless speakers I've owned (I also have a few from The Sharper Image), the Wolverines produce a surprising amount of bass. On the other hand, the high frequencies aren't the cleanest, but overall the sound is satisfactory. Yes, all system components use traditional AC adapter plugs that take up space on the power strip. I would recommend Wolverine to follow the trend I've seen with laptops where there is a cable between the wall and the transformer. But using an AC adapter is understandable given the performance of the speakers. USB not working; All of my previous wireless speakers have used power adapters. In general, I am satisfied with the system. Its performance is better than Recoton or The Sharper Image systems, with less noise than either (Recoton had to be manually tuned). The sound quality doesn't blow you away, but they're okay for what they are. For audiophiles, get an expensive Bose system.
