Review: 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
Review: Quality Speaker - It is a great 👍 speaker with plenty of volume. It appears to be very well made in Germany and England as point of manufacturing. The battery does last 18 hours. I wish there would have been a little red light on the front, when it is on, like there is on the back when it is plugged in. It makes a very quiet tone on start up and shut down. Overall, for what it costs, it is a bargain!

### ⭐⭐⭐⭐⭐ A perfect mid size portable speaker for the price
*by J***N on December 21, 2025*

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.
