TUNED BY A MASTER MUSIC GEEK

"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."

  • SOUND YOU'LL WANT TO SHARE

    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.

Impressed with the sound for the price

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.

Excellent haut-parleurs UBOOM L

Son merveilleux et riche avec beaucoup de base pour un si petit haut-parleur. Je recommande vraiment cet achat. Le son mode extérieur est à privilégié. Merci Earfun pour cet excellent produit.

Just the right compromises

I’ve tried a bunch of Bluetooth speakers and The UBOOM L sound is my favourite! Very detailed, easy listening and loud enough. It’s looks and battery life are OK but it’s price is wonderful! I have a Mac so I can’t update its firmware.

Good office speaker for near field listeting

I needed to upgrade the firmware. Without upgrade it was not so good. The hardware on the other had is good. A combination of good tuning and good hardware is a must and I think this time this EarFun product is a successful combination. It has the same sound signature of a EarFun Free Pro and Pro 2 after Ovuvs EQ is applied. I hope this collaboration will not end here. I think there is a very long way till many educated buyers know how good sounding devices should sound like. Clear, punchy, sparkly and open sound - that should give us a joy. And for such devices should a producer target his/her creation. Good luck.

Earfun UBoom L

Good speaker overall. It should have attatchements for clips or lanyard like Bose soundlink flex or jbl flip. It should also have online app for easy updating and control of speaker. However, it is still a good product.
