Alternative for other sounds systems ? Maybe 😉
As you might see, I bought two of them, when I found out that they can be connected to eachother and play as stereo system. When I have set all up, and I played some music, I was amazed how loud this can be.. The bass sounds like it would come from subwoofer. Clarity of the sound makesb it very pleasing to listening, you can choose wether you want or not the bass boost, and when they are connected together, you can just simply press and hold on one of each M/Bass button in order to disable or enable Bass Boost. Battery life is outstanding, as well as connectivity, because pairing them together is almost flawless, just press on each after turning On them, TWS button, them they will automatically connect together. In my opinion, White colour and decent size, makes them look futuristic, especially when you don't need for any type of cables in order to use them. I only connect them to charger using long usb C and a charger with 2 45W connectors, just in order to charge them without moving them around just to charge them. They are quite expensive, and I bought them with a discount, which is showing here sometimes, and I would love to see LDAC or any Aptx support in the future models, because they're using SBC only, which isn't ideal, but sounds great anyway. Overall in short answer, do I recommend them ? Yes and no.. yes if you can find them on the discount, not really if paying full price (especially when buying two of them simultaneously)

Fantastic sound, classy look!
Bought this during a prime week. It is worth every penny. Produces a beautiful sound and it looks expensive. I would pay full price for it.

Nice Sound for a Small(ish) Speaker
The sound is good - I am using this for a portable keyboard set-up to go into care homes (everything is battery powered). It works better if you get it up against a wall (adds wall reflection). I had hoped for a little more bass, but it is good for groups of 20 or so. I have owned smaller DOSS speakers before and thought they gave good performance for the money - same with this one.

Excellent sound!
This was bought as a Christmas gift - read reviews and totally agree the sound is beautiful. Impressed the family too. Size is bigger than most bluetooth speakers but that's not an issue... easy to pair, honestly great value for money - thrilled I saved so much on Black Friday deal!!

Don't waste your money
Really poor quality, got it for 99.99 instead of 179.99 but not even worth 9.99. So much better options out there stay away from this brand and this speaker.
