Bose sound and quality, as far as manufacture, are as expected excellent. However, the wireless and connectivity between speakers has been extremely frustrating. Also, you cannot access iTunes directly over the Bose speakers because Bose does not let you add iTunes as a normal Music service. The only reason I can think of why this is the case, is that Bose is trying to save money. I am sure Apple charges a premium to be able to connect iTunes to a system like sound touch, or Sonos, but I think it is ridiculously short sighted on the part of Bose not to add it. It really limits its use with one of the most popular music services, iTunes. If most of your music is on iTunes, then definitely choose the Sonos, because whatever improvements Bose has made to the SoundTouch quality with their latest system, you will not be able to easily access your music library. You can connect iTunes through airplay, but that causes even more frustration. It is nearly impossible to use airplay with multiple speakers, without constant dropping out of a speaker, or the system simply refusing to work without a complete reset. It is likely that Bose has improved their system. I am using one of the older series, so my experience might be better with the new system. However, I purchased a Sonos system for my office at about the same time, because of my frustration with the SoundTouch system at home and the overall system runs much more smoothly, I never have to reboot, or have any struggle playing multiple speakers, which is just not the case with the Bose system. With the SoundTouch system I am constantly having to reboot, or unplug the speakers and reset them in order to get them to play throughout the house. Even when that works for a while, it will shut down periodically, or one room will drop out, etc. I am using a top line Asus router, on an extremely fast network connection at 5 GHz, that the SoundTouch uses almost exclusively, to try and keep things clean for its wireless connections, and things just simply don’t work well. Also, I believe the Sonos sound quality is just as good as the Bose and connectivity, or speakers dropping out, just never happens. I am in the process of replacing the five SoundTouch speakers I have throughout the house with Sonos.
