Great speaker, great price.
I have to basically rewrite this review... update as follows: I tried this speaker again after receiving a warranty replacement of one that had been damaged during shipment and making noise the whole time of use but finally affecting sound. But the new speaker sounds amazing whether you use Bluetooth or aux connection. I cannot believe how good this truly sounds and now I am a true fan of Doss and their fine products as this is their third model that I own and love completely. This is an easy speaker to use, set up and operate. It has a bass boost which I don't use. Just leave it set at its default which is set to its fullest and sounds its best. Less and it just sounds way lifeless. Bluetooth pairs pretty fast but not as fast as the latest of gadgets out there today. But the sound quality and amount of volume and richness achieved the louder you go. Just buy this speaker already, it's beautiful and sounds great. You won't be let down. Unless you get a bad one. Then mail return it or call the company. Calling Doss is painless. They're so great! Thank you if you've read this far, Erin V Previou review---@ 4 ✨️✨️✨️✨️ The sound quality is pretty fantastic if you use a fair quality or better wired 3.5mm to 3.5mm aux cable that is not included to connect your media source to the aux input connection of this speaker. I did not like the Bluetooth of this speaker, I admit I have audiophile or hifi taste that I sometimes like to adhere to when it is available and this speaker lives up to those standards quite capably when using the wired connection. At original settings I did not like the beeps that are at power on and again at off and then at another time I can't remember, they are a little bit obnoxiously loud. I think the light that indicates what is going on as far as what setting you are using or what input you are using is very useful but is hard to see at its current location depending on where you locate the speaker and the indicator light could maybe be located to a central part of the speaker. These 2 things, the light and the beeps can be disabled, by the way, if you'd like, it's mentioned in the instruction manual. If I could redesign this speaker I'd include a remote to the features of this particular model as this isn't very portable and likely to be indoor permanently by most users. A remote should definitely be in the future for a continued model of the like for the on/off and a few other controls such as maybe pairing and bass boost. The remote would also set it apart functionality wise apart from the long list of bluetooth speakers on the market. It has a very slight learning curve if you are new to the world of Bluetooth speakers, but if not everything functions as it should and has no problems that I have encountered. The instructions are very helpful if you are new to this type of speaker however. The included (charging) cord is a fine length but should be permanently connected and with a wall plugin on it in my eyes. At the current discounted price it is an exceptionally great value and even at slightly less than original price is a great price. I quite enjoy the sound of this and must find out how it improves by adding a second speaker so I am now needing to buy the second one, so be warned you may also find yourself with this curiosity and want to buy the a second speaker. Haha

Great!
Great product. Buy two for seamless stereo bluetooth awesomeness. This product is a great reminder of how the "ceritifaction" of "High Definition" audio is meaningless. You won't find any gimmicky "certification" labels on this product. It just sounds great and runs a really really really long time on one charge.

A perfect mid size portable speaker for the price
This is an amazing 'portable' speaker. It has a quite large size which makes it hard to bring to places, but for casual listening it lasts long and it sounds phenomenal. It sounds good enough for one to notice songs that are lower quality vs songs that are very high in quality which is a first for speakers tried personally. That makes it an 8.5 out of 10 for me, and especially in its price range. I reccomend one. The only thing unfortunate is to get the max bass out of it you need to set it in a mode for bass and configure an EQ for bass, and that makes the audio sound slightly distorted(muddy almost). Nevertheless, this is a good product, and if it goes on sale it is definitely worth picking one up.

Buyer be ware. Sounds great, but two of them went bad on me.
The first one I bought lasted about a week before it died. Second one I got went out with no volume control at about 8 months. Sound is great as long as it works.

Short Battery Life is Frustrating ... but Customer Service is highly COMMENDABLE!
UPDATE: I bumped my review up to 4 stars because shortly after leaving my initial 2-star review I was contacted directly by the support service and they were VERY helpful in arranging a settlement of my initial dissatisfaction with the product and I was extremely pleased with their direct and prompt after-sales service. At least they stand behind their products with extreme care and for that I am grateful and have the utmost respect for this kind of attention to customer service. Giving it 2 stars because it's not totally horrible, but close. I liked the look of the enclosure in that it doesn't have that black "look, I'm a speaker on your counter" appearance. The sound is decent for what we needed it for - some decent music in the kitchen. But the thing doesn't seem to hold a charge long enough to be ready when we want to use it. If it sits too long between uses it loses its battery life. You apparently have to keep it plugged in all the time to keep it ready to go. Disappointed considering what it cost and then by the time I figured out that we weren't pleased with it - the return window is LONG gone.

This thing is a KEEPER!
I'm totally satisfied with this bad boy. Keep in mind before you buy it that you can't connect to it with Bluetooth if the line in is connected. You can't even pair with it if your line in is connected to something so line in has priority over BT. It would be nice to toggle between the two. The sound is amazing and it replaced a small Dell monitor sound bar that attached to the bottom of the monitor. I was thinking of getting a used BOSE Wave radio as their sound is great. But this is just as good and it's portable with it's 16-18 hour battery, can connect to anyone's BT sound source or get wired with a stereo mini jack. It's heavy and exudes quality and the sound is great with a very wide freq. response 45 Hz to 25kHz. JUST BUY IT!

Sound auto shuts off when you leave for a few minutes
You have to keep turning the speaker on if you get up and then come back to your computer and want to have sound, it autho shuts off. ANNOYING. Otherwise, great speaker, wonderful sound but this makes no sense at all.

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)

Great sound
Great blue tooth speaker, the sound is amazing, I can connect various bits of kit from quite a distance away. It is stand alone or mains connected. Looks good and is nice and chunky.
