Bests & Worsts Reviews from Amazon

To put everything right from the beginning: this speaker is a clone of the Sony SRS-X77 but with an own tuning and without all the Wifi-features, although the driver layout and body is exactly the same as the Sony. The same speaker is also available with Wifi from IdeaUSA although I haven't heard that and cannot say if it really sounds the samy as the Doss. Funnily the Doss sounds even better than the Sony with its default tuning and it plays deeper bass, but it doesn't play as loud but is still one of the best bargains you can get below 100$ if you are looking for a serious sounding portable speaker without spending a fortune and don't need the speaker to be the smallest size. I can tell you that this plays on the same level as a Vifa speaker costing 4-5 times as much, the only difference is, that the Doss Soundbox XL has quite a limited overall volume compared to the more expensive top performers, but the good thing is that it still remains perfectly usable even up to maximum as there is no distortion or any strange dynamics processing that you usually get from many other speakers in this class. The sound becomes a bit thinner above 3/4, but put it closer to a back wall or into a corner and it will sound like a big speaker. As there is no artificial upper-bass boost, it won't become boomy near a wall but it will rather enhance the deeper bass frequencies, making it sound way bigger than it looks. Battery life is outstanding, I got more than 5 hours at maximum, which is great for a speaker of this class. I must say that from all the portable Bluetooth and wireless speakers I have tested until today (which were close to 300) this is the one which impressed me most regarding price/value factor. You really get the maximum and best performance you can expect for that price, if you don't expenct any party loudness levels or boomy exaggerated bass. Skip everything else below 100$ including the high regarded brands. This Doss speaker really competes with the mich higher end class. There is of course still some room for improvement like lowering the loudness of the status tones, which are too loud for my taste and cheesy as they are original Windows tones, and I would also add some dynamic bassboost for low listening levels, then the speaker would be unbeatable. Obviously most of the praise has to go to Sony, as it is clearly their design which was "recycled" for this speaker, but the ones who tuned it, did a better job than what Sony was able to achieve with the X77. PS. my unit had some rattling with deep bass notes, but after closer examination it turned out to be just the grill or rather the loose fabric put in-between. I removed the fabric, remounted the grill and there is no rattling anymore!
