Loud, Crisp and Thumpy.
Overall great package. Directly competing with the Tribit and JBL flip 6. Good Build Quality. I did not expect the sound quality of this product will be this good. Very Premium sounding speaker. Goes very loud. But the only issue is when you ramp up the volume to it’s Max (100%), the bass becomes thin, the trebles and the mids kick in. But there is no distortion at all at any volume, even at 100%. It would have been nice, if there is App support for this speaker. Very happy with this purchase. Had to exchange the product because I received a damaged and defective piece. The battery life is also satisfactory. Can play upto 12 hours at 80% volume. The sound is crystal clear, crisp and sharp. Enjoying alot. Updating the Review after 3 months of usage. Had to replace the Product because of receiving a damaged product and firmware couldn’t be updated. After the exchange, I could update the firmware to Oluv’s Tuning. I recommend every one to use the Oluv’s tuning. The stock tuning is not good. But the increase of volume levels in stock tuning is very good. The overall Loudness, Bass, Treble balance is good in Oluv’s tuning. Oluv is an Audio Producer who has great emphasis on sound and audio products. Review after 1 Year and 3 months. On 06-02-2026 Now the Speaker got app support. You can change customise the sound with the EQ. Still sounds good. Good battery life. I really love the speaker. Very clear mids and crisp highs. Bass is really good. But if you increase the sound to 80% and more then it becomes treble heavy but still sounds good but a little less Bass.

Rich Sound - you'll love it. But read review.
Don't expect much with bass. But with sound clarity and quality in richness is superb. Connectivity is great. Battery is ok , i should have been better definitely.

Worth it.
After 7 days of research in reddit, YouTube I finally ordered this. My other choices were: 1) Jbl flip 6 (at 7.5k) 2) Tribit stormbox 2 (6k) 3) This (5k) In all YouTube comparisons video this sounded better than jbl flip 6(smoother treble) and way better than tribit despite being low price. Also reddit were full of positive reviews of this speaker. After ordering I was truly impressed. -The bass and sound stage is separate. -Vocals and other instruments aren't overpowered by bass. -Treble is quite smooth. -Sound is quite loud. Has an app. download it. People will tell to use oluvs eq. But I liked the "More treble 3" eq setting.

Balanced sound with premium built
Sounds way better compared to it's price point. The speaker has a balanced sound profile with right amount of bass. Loud enough with default EQ settings. For a 150 sq.ft. room you won't feel the need to push the volume beyond 30% for normal listening. Switching to Oluv's drops volume significantly. Personally I felt the default EQs sound better. Bluetooth connectivity is smooth. Great built quality. It has premium look and feel.

Oluv's firmware will enhance the sound!
Worth the money if you can flash oluv's firmware 😉

READ THIS , If you are considering to buy Uboom L
Bought it after so many recommendation from reddit. Was doubting initially because some people said it is overhyped. But now as i have this speaker now, those people might be listening to it on wrong firmware. It took me less than 5 minutes to update the firmware to 1.2.7, which is the best firmware as per a lot of research. You can get the google drive link for update and instructions from reddit. You would need a laptop and usb 3.0 cable which i took from one plus phone charger. Once updated download the Earfun app on ios or android and this speaker will show up. Go to the eq settings and select oluv’s indoor (outdoor can be switched automatically with the button on the speaker) and you are good to go. The packaging is decent. As for sound; Best in this price range. It’s very FUN to listen to. Vocals and highs clear and well separated and bass is really good. I mean the more i say the less it is. LISTEN TO THE RECORDING. Sorry for the short review. I am lazy when it comes to reviews.
