I bought the Edifier Bric Connect, because I already know Edifier products and know that is super quality at a low price and resonable. I myself still have the Edifier Aurora 2.1 sound system (qid = 1416821481 & sr = 8-1 & keywords = + Edifier Aurora). I once had a Over-Ear Headphones (qid = 1416821698 & sr = 8-1 & keywords = Edifier headphones +% C3% B6rer + H840) was also very good. The Bric Connect has for its size and a capacity of 2 x 6 watts (RMS) an excellent sound, what has impressed me immediately. However, greatly vary qualitatively sound, depending on what you connect to a source of the music to the speaker. For a very cheap China MP3 Player, although it has some preset sounds, the Bric Connect sounds good, but the bass is not as good over. Even with the heights missing since much good stuff. Then I got the Bric Connect to an LG G3 smart phone connected to the I use the PowerAMP - app that can all important frequency ranges set itself very well. What then so comes from the Bric Connect to sound out that is worlds better then, than the cheap China MP3 Player. If you still have direct power connection, instead of battery listening to the music, which is also sometimes notice a difference. That will really loud without rattling because the bass is also very good over. For additional positive impression comes moreover, that all my MP3 songs are in a very high bit rate. (320 kbit) In a bit rate of 128 kbit, it's not quite so loud and the bass are less present. In direct comparison with the Bose SoundLink Mini I could hardly notice a difference, and a friend, with the Bose bass presence to be something in the foreground, but this is a matter of taste. The Bric Connect has a better and ausgewogeners sound compared to the Bose SoundLink for my ears. And that's a very high bar, I think personally. One can also use normal AA batteries and AA batteries, is also a very good thing. The batteries in my case, I always use Duracell Alkaline MN1560, these keep me around 20 hours when I do not hear too loud. Listening at loud, is yes then also consumes more power. I have the power consumption measured times with a consumption meter. At full power up to 16 watts are consumed electricity. But that is the maximum output of music performance that has the device then probably. Final three hours with his sound - inside the battery or battery operation would then certainly by 2. I recommend he prefers using the supplied AC adapter to hear. What is missing on the device is the ability to jump into the songs back and forth, that is only possible on the source device (smartphone) and even via Bluetooth connection. But sound Technically the Bric Connect a 100% buy recommendation
