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 VPreviou 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! *by on Reviewed in the United States July 30, 2026* 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 *by on Reviewed in the United States 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. ## Frequently Bought Together - DOSS SoundBox Ultra Bluetooth Speaker with 2.1 Channel Audio, 80W Superior Sound with Deep Bass, Two DSP Technologies, 18H Playtime, BT 5.3, Wireless for Home, Office, Bedroom-Gold - AC Charger Fit for DOSS SoundBox Touch Pro Pro+ Plus E-go I II Traveler Bluetooth Speaker with 5Ft Micro USB Charging Cable Power Supply Adapter Cord --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/613560975-soundbox-ultra-bluetooth-speaker-2-1-channel-audio-deep-bass](https://www.desertcart.sg/products/613560975-soundbox-ultra-bluetooth-speaker-2-1-channel-audio-deep-bass) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-08-28*
