Summary: I'm big Bose fan but honestly these speakers really disappointed me. The speakers would skip beats at high volumes. At high volume, the music of the song would be a lot more prominent than the singer's voice. I was upset that these speakers had 'bose' logo on them.
Summary: Got this and was very disappointed as the audio sounded indistinct/weak/lacking in highs. The audio lacked resolution. I am using the Bose supplied cable. Finally out of desperation, I pulled the 1/8 input from the back of the speaker and plugged into the input at the round cable control. Wow - HUGE difference in audio. I thought I must be imagining things so I tested it over many tracks and different type of music. I also pulled and replugged everything multiple times.
Summary: I bought these based on the stellar reviews and my desire to upgrade my old speaker system. Right away I noticed they sound worse than my $15 garage sale Sony speakers. Now about two months later and I still don't like them. They sound terrible. They are not clear and have a muddy, overbearing bass response. The speakers can only be about 4 feet from each other, and have a proprietary connection system. Same with the controller.
Summary: I got these because they sounded amazing in the store. Was willing to pay the premium for the BOSE name and the control pod feature. Would have given 1 more star if the price was lower. The sound quality while good and better than most speakers, is not phenomenal. The aux cable that comes with it is really short so had to buy an extension aux cable cable.
Summary: I thought Companion 20 would give me the bass I was looking for missing from Companion 2. Not the case at all and jumping from $99 to $249 for Companion 20 was absolutely not worth it. Went with the Klipsch ProMedia 2.1 and am so very happy. More affordable as well.
Summary: My intended use for these speakers is most likely much different than most, but thought I'd pass along my experience just in case someone else may be considering these speakers for the same reason. I play classical piano and use a weighted Yamaha keyboard for practice (since I can't afford a Steinway D), along with a couple virtual piano programs which are sampled Steinway concert grand programs that run on my computer and connected to the keyboard via a MIDI cable.
Summary: So you don't want a subwoofer? And you're willing to pay more money for a crappier sound? What? Something like the Klipsch Promedia 2.1 system is waaaaay better than this and is also a lot cheaper! The sub is small enough to be unobtrusive but is still quite powerful. I tried the Bose 20, but found them really lacking. If you really really really absolutely do not want a sub, then fine. Spend more and get less.
Summary: I like the sound from the Bose Companion 3 and 5 models. The Companion 20, however, are not balanced; midrange and treble are drowned by the bass, and the overall sound is boxy. You can do far better for around the price with the Audioengine A2 Black (Pr) 2-way Powered Speaker System or Audioengine A5 Powered Multimedia Speaker System (Black)
Summary: I have owned the Bose Companion 5 speakers for several years and have been quite satisfied with them at home. Last year I purchased the Creative GigaWorks T3 2.1 Multimedia Speaker System for my office and was quite happy with them. However one of the speakers "died" and I returned them. While the sound of that system was very good, the build was in no way comparable to the Bose Companion 5s.
Summary: It amazes me that other people are praising these, the bass is so overwhelming that it pretty much ruins whatever you're playing, whether its dance, rock, folk or soundtracks. Not only are they uncomfortable to listen to, I'm not able to relax knowing that the bass is so intrusive and travelling through the walls and floor.
