Review on DOSS SoundBox Pro+ 24W Bluetooth Speaker: Impressive Sound, Booming Bass, IPX5 Waterproof, 15Hrs Playtime, Wireless Stereo Pairing, Mixed Colors Lights - Green, 66 FT Range by Mark Repp

The name says it all. The other reviews will tell you most of what you really need to know, so I'll just add a couple of caveats covered in the manual. unspecified: (1) Specified battery life is 15 hours when not using lights or extra bass. In my practical everyday experience of using it, I get up to 10 hours in cases where I really need some volume (so isn't my normal everyday BT speaker). (2) Speaking of extra bass, they really shouldn't have called it "extra bass", they just called it "bass". This is because even if you set the EQ curve of the source material or presentation for bass, none of these speakers actually have the "Extra Bass" button turned off. You have to turn it on to have bass. (3) Busy phone-like noises, two from time to time at intervals, is an indicator of low battery and in my opinion they seem to start when battery life is 1%. This is one of my favorite problems with many BT speakers, that they turn on too early regardless of the low battery warning when about 15% of the battery is left. And sometimes that warning is intrusive and interferes with what you're hearing. This device sounds an alarm at the correct interval, IMHO with 1% left, and doesn't interfere much with what you're hearing. (4) It's quite large, with decent materials, especially along the right and left sides. It's actually harder than it looks. (5) I usually find lighting schemes crap, but every once in a while they can be interesting with the right song. (6) The overall sound quality isn't the best, even among the BT speakers I have, but I don't have expensive ones. But that's to be expected for the price. It's getting pretty loud.
