Polk Omni S2R Rechargeable WiFi Speaker

Let me start by saying this is a well-built speaker that puts out great sound. It's particularly nice to have a rechargeable wireless speaker that's part of a larger whole-home system. This is one area where Sonos falls short. They really need to release a rechargeable Play 1. Now, though this speaker puts out great sound, I was disappointed by the technology that supports it. The iPhone and Android Apps are functional but a bit unwieldy and not entirely intuitive (and I'm an IT professional). The Windows Play-Fi app was a little more functional and would allow the redirection of any audio on your PC (Netflix, YouTube, etc) to the speakers. It was annoying that the Free version of the software wouldn't allow streaming to more than one speaker at a time. For that, you need to buy the *premium* version of the software for $15. That, or if you register your speaker(s), you get sent a one-time activation code for the premium version. I found that when I registered my second speaker separately, I was NOT sent an additional activation code. I found the activation code I received wouldn't work on my second PC. Some of us have more than one PC, y'know -- are you listening, Polk? Also, if you need to reload your OS and re-install, you're sort of S.O.L. Conceivably, you could use something like 10-minute email (or similar) for temp email addresses to register fake serial numbers to get extra reg. codes. This is a lot of work. They should just give the darned software away. Now that I've vented, I'll continue. I really REALLY wanted to like these speakers and feel like a shrewd consumer for getting something comparable to Sonos for 30% less. I just never reached that level of satisfaction. These speakers required frequent reboots and would sometimes fall out of sync, with a significant echo from room to room. These won't be difficult for someone that's reasonably tech-savvy to set up or support. I've noticed that my *wired* home-theater speakers just work without being finicky of requiring any fiddling. Always. Period. Even my Acoustic Research wireless speakers don't require any TLC. Instead, they just sound like crap, motivating me to upgrade. You shouldn't need to reboot the speakers and they shouldn't be finicky. The Polk system was just annoying. I bought three speakers (1 rechargeable and two standard S2s) as well as a P1 to presumably use as a source, utilizing the aux-in (so I could stream CDs or other legacy sources). I was profoundly disappointed that feature is not supported (why on earth does the P1 have the aux-in then?). Perhaps that was the start of a grudge I was going to hold against these. Still, in their defense, the speakers sound absolutely wonderful. Great, rich, deep sound. Perhaps in a few years, this will be an exciting alternative to Sonos. At this point, I'm returning mine to go with Sonos and a Connect unit to accomplish what I want.
