Right, a word of warning here! Do not buy. I went by the reviews and returned the product. Yes, it is really loud and has surprisingly clear, distinct mids and highs (perhaps too much). This means that at a high volume, it will blow your ears off, but at a low volume, you won't hear much bass even with the bass boost on. This can be sorted with an equaliser, but unfortunately, this speaker doesn't have an app, so you can only equalise it in the Spotify app, for example. I would have even kept it because it really is a party speaker, and you can tweak the sound with an equaliser. But now for the biggest problem, which a layman probably won't notice – hence the positive reviews, apparently. It will play decently with the bass boost on up to about 40% power, and then it starts to fluctuate, dipping the volume. It either has some kind of limiter, but I would expect that more at higher volumes. It seems to me that when there's more bass, too much energy goes to the bass speaker and the rest gets muted; during a non-bass passage, it suddenly starts to blare like crazy. Even turning off the bass boost doesn't help. Adding bass on the equaliser in Spotify makes the problem even worse. The battery apparently can't keep up with supplying juice to the amplifier. Unfortunately, it also hisses. It's a real shame, I really like the look of this speaker, and if it were properly finished, it would be major competition for more expensive brands. This wasn't a faulty unit; they'll all be like this, I read one review with the same problem. I don't understand how someone could have botched it like this. I was thinking, Sencor has outdone itself, with all these positive reviews, this is going to be amazing. No, I was wrong, it's just a Sencor.
