"I put my entire effort into offering you a premium sound quality at an affordable price. The main focus was to provide an honest and natural sound reproduction in all environments and at all volume levels. Indoor mode is tuned towards a smooth flat response without enhancing any frequency spectrum, while outdoor mode gives you that extra bass and clarity with increased loudness for a more assertive sound to be enjoyed in more noisy surroundings."
Enjoy deep, punchy bass sound with EarFun innovative JumboBass™ technology UBOOM L speaker. Dual passive radiators work together with the 55mm dynamic bass booster speakers to enhance low-end tones, giving a clearly punchy bass sonic experience.
The layout of the side passive radiators has been optimized to reproduce clear bass sound.

Une tres belle découverte !
Le son est très bon, les basses sont profondes : un excellent rapport qualité prix !
Just wow... I bought two of these speakers and the sound is superb. Oluv's tuning is spot on. Great job Oluv!!!
Több vélemény és teszt olvasása után választottam az EarFun UBOOM® L-et és nem bántam meg. Jó a dinamikája, de nem zavaró a basszus, tiszta a közép és magas hang is. A kidolgozása tökéletes, az anyagok minőségi tapintásúak. Ár/érték bajnok!!!
Hi,sound superb ,firmware oluv 4.8 ,outdoor setings,
I was surprised by the sound and I'd recommend checking this speaker after firmware upgrade. I don't have much experience with BT speakers except for JBL go 2 but I have USB dongle Colorfly CDA m1 and tried several Chi-fi IEMs + Grado SR80x and also can judge by comparing with car audio of my friend's Audi A3 and Jaguar F-pace (I have Ford Fusion with more simple sound system with less density in bass). Comparing to IEMs for sure there's less detail in highs/mids in UBoom and stereo sound stage is much more narrow for only one speaker but overall feeling is a sound of a premium audio for sure. Very detailed bass, not boomy but dense. Want to buy second speaker one day to have wider soundstage. Thanks to EarFun team, great job done.
