Summary: After using these for four years, I bought a set of B&W MM-1s from Crutchfield. The difference is like night and day. The MM-1s are so much clearer and don't have the muddy sound that the Bose do. B$Ws are higher than the Bose but I fell worth every penny of the difference. If you want really clear sound, save a little more money and get a set of B&Ws. If you want the fake surround sound, get the Bose.
Pros: These are pretty good speakers that do what Bose says they will. They produce a full and almost beleiveable surround sound. I've had them for four years now without any major problems. Seems to be a well made product.
Cons: For the price, you should get more. Another dislike is the same as one thing I like about them, they do what Bose says they will, nothing more. The sound should be cleaner than what it is.
Summary: I bought this set of speakers almost 3 years ago (They have not changed since to my knowledge.) so I have had quite a bit of time with them. I must say that, not considering the price, they sound decent; much better than a generic PC speaker system. That said, when you take price into the mix, they are not worth the money. The sub tends to have a muddy sound to it and the "full range" speakers in the 2 stands sound washed out most of the time.
Summary: I've had the Companion 5 system for about a year, connected to a G5 iMac running both Tiger and, for the past month, Leopard. Often the sound from these speakers simply stops. The only way to get it back is to re-boot the computer. If you study the Apple Support Discussion Forums you'll see that I am not the only Companion 5 owner who has this problem. You'll also see that, to date, neither Bose nor Apple can offer an explanation or a solution.
Summary: I have a Bose Companion 3 (the original, not series II). Mostly what I use them for is listening to music on iTunes from my Mac laptop while I work on the computer in my office. Most of my iTunes music is 128 kbps bit rate, so we're not talking hi fidelity here. When I want real high-fidelity, I listen to a CD on my home entertainment system. I have been VERY happy with the Companion 3's with this set-up.
Summary: The sound of these speakers is great, But I keep having problems with them. When my computer goes to sleep or restarts it can't find the speakers so I have to constantly re-Install them. What a hassle !
Summary: As an audiophile I sample lots of speakers systems whether they are for home theatre, two channel listening, or computer speakers. In all catagories Bose speakers have been over priced for their performance. Ever since Bose came out with their 901 line, Bose has presented themselves as the Ferrari of home audio. But sadly the rest of their products just don't live up to the 901's quality, and these are no difference.
Summary: Beware of getting this if you are running win7. Had my system for about 10 days now and 3 times it has quit working. A quick google reveals page after page of win7 users with the same problem but funnily enough no XP or Vista users seem to have any issues. Answers range from a reboot to a system restore to fiddling with all sorts of settings. Sadly today no solutions worked and after a full morning trying to fix the problem I found the answer (until the next time?
Summary: Pros: + Great sound quality + Solid + I like the design Cons: - Cables are not fixed properly. Too often the speakers turn off in the middle of a song or a film, because the cables are extremely sensitive to be properly connected. Very annoying habit, and I cannot do anything about it. - The bass control is very basic and it's at the back. - Very moody when used from USB connection.
