Bluetooth Speaker, UBOOM L Portable Speaker, Rich Bass

Having owned this for over a year now I thought it time to write a review. My original intention was to buy a mini rig to take on holiday and for using on our small boat as they work great outdoors. I was put off though by their lack of waterproofing and high cost. After doing some research I came across the earfun boom. I was a bit sceptical but intrigued at the random guy claiming he tuned it to almost perfection however other reviews showed it to be truly waterproof and good value for money. I used the discount code on one of the videos and bought it. The build quality looked great and from the very outset I was impressed by the sound. Taking it abroad I mainly used it by the side of the pool, on the balcony in the evenings, and for some background music in the room during the day. In all places I found the sound to be of great quality. I listen to a lot of music, sometimes through quite expensive speaker systems and I have to say this punches well above its weight. There's never been an occasion where it wasn't loud enough. As for the quality of sound I tend to listen to Rock and Metal. The sound is excellent and makes for a great listening experience. The battery life has always been more than enough. It's very durable as it's been bounced around work vans, and gone from one overnight bag to another. It's definitely waterproof as its been out in the rain and been thrown in bags with wet beach towels. I tend not to go on trips without it now. Some of the lads at work have big JBL units which although are louder definitely lack the quality of this. Even in a workshop environment it works well. The connectivity is seamless and its simple to set up. Without a doubt there's louder and better quality speakers out there but there always seems to be a down side. Either they're not waterproof, poor battery life or just stupidly expensive. For the money though this is a great all rounder and I love the sound quality and robustness. My only criticism....and it's certainly not a deal breaker, would be that when I throw it an a rucksack it's easily switched on by accident as the buttons sit proud. A recessed power button would be a great improvement. Another suggestion would be that they make a hard case available as I'd definitely spend the extra money to keep it better protected when it's not in use. Other than that I've been very happy with it. I'm very tempted to buy a second one for stereo sound as I think it would make for an even better listening experience when outdoors. I really don't feel the need to buy any more other Bluetooth speakers now. Yes, I'd highly recommend this!👌 Update. I bought a second one so that I would have a stereo pair. I used it recently outside at a family party. The sound quality was excellent, more than loud enough for a large garden and was fine when it started to rain. The battery's outlasted us......from around 5pm to about 4 in the morning and still had enough juice for some background music the next day before we went home. Awesome product. I'd still like to see an option for a soft shell type case for travelling.

I bought this speaker as a replacement for a Jam Heavy Metal (very highly rated speaker from a few years ago with an original RRP of around £120). Predominantly it’s getting used in a commercial kitchen, so it does get pushed at over half volume in a noisy environment. First up, the sound quality is better than the Jam. It sounds fuller, instrument separation is fantastic and timbre is really good, in all honesty it’s a much better speaker than my old Jam. It goes loud enough, though there isn’t a massive amount of headroom in my use case. If you like ear bleeding volumes, perhaps this won’t be for you unless your environment is small. Connectivity is great, though in this day and age you’d really expect that. Anywhere in my one bedroom flat remains connected and I can walk around work with no drop outs. So, it connects well, it sounds great, why the dropped star? First up, the build quality. Already the material covering the speaker is starting to look “less new” with a couple of small frays. I’m not a clumsy kid, I’m a middle aged man who looks after his gear. Yes in this instance I’m using it less carefully than I might for home use but I worry how rough it will look after 6 months. Finally, the battery life. It’s disappointing. I know claims are for “up to” yada yada yada but in actual use I’m only barely seeing half what’s claimed. If I’d known it would be that bad, I’d have bought something else (it was bought for a specific use case and it’s not quite up to doing a double shift in the kitchen). I don’t regret buying it, as it sounds great, it’s just about the perfect size and it’s close to being able to do what I want. It’s just not quite there. So, after 6 months the physical condition hasn't got any worse. The battery life is still not amazing but it'll go between 8 and 10 hours depending on volume. Sound quality as it's worn in is just really, really good. Plenty of depth to the bass without it ever becoming boomy or false-sounding. Quite happy to return the star I dropped it now. It's great.

Having bought EarFun wireless earbuds in the past, I already knew the brand delivered excellent quality, so I decided to invest in this UBOOM L portable speaker for my camper van. I needed something to boost the sound quality of my portable TV and to play music when relaxing, and it certainly does not disappoint. ​The sound quality is surprisingly rich and powerful for such a compact speaker. It has never let me down, and when it’s not in use, it's small enough to easily tuck away out of sight. I am incredibly happy with this purchase—it's an absolute bargain for the performance you get.

Ordered 2 of these on release day after really enjoying the original Uboom speakers and being a big fan of Olufs reviews. The pairing process was fine and the 1st speaker was up and running in no time. And from my P30 pro, the sound was great. Much better in outdoor mode however. I have no idea why you would use indoor mode at all. The bass is superb for a speaker this size( don't expect bass to be shaking the room for a 50 person house rave) and the treble is clear and crisp. I also find that the sound changes quite a lot on placement. There were some places where bass seemed to drop off almost totally. I had been playing music from my phone's music widget. As soon as I open up the default music app for more settings and to see the full list of songs, the speaker stops playing and will not restart. It doesn't matter if I close the full player, and try from the widget again. It just won't play. As if the speaker has crashed. I don't have this issue on any other speakers I have including the original Uboom, so it is clearly a firmware issue. And then when I turn off the speaker, it makes no sound but all the lights go out, but my phone still shows it is connected. No idea what's going on. And it is actually still connected too. If I unpair via my phone, the speaker Bluetooth light will suddenly start flashing again. Like it didn't turn off at all. And I can't turn the speaker back on until I have performed a speaker reset with the -&+ volume keys. It's well messed up. I have since tried it with the Spotify app, and it's worked ok with that. So maybe it just doesn't like the Huawei music player. Such a shame cos the sound is generally brilliant and I'm sure it'll sound even better once I've paired the 2nd speaker for tws, but at the moment, I'd be happy with just 1 speaker working correctly. I have been on earfuns site, as Oluf mentioned about downloading the latest firmware, but as yet, no new firmware exists on their site. Just a blank list. So hopefully I will be able to update this review in a few weeks when everything is working as it should. I have still rated it 4 stars as you will not be disappointed with the sound.

I've previously owned the Denon 250BT Envaya (all time favourite portable speaker), JBL Charge 4 (nice bass but not balance and bass cuts out at high volumes) and currently own Audio Pro BT5 (not very balanced, needs EQ to get the best out of it) Compared to those the UBoom L is closest to the Denon in style, size and performance but it has an even more balanced sound and better clarity over all my previous owned BT speakers. The sound is on the warm side, though not as warm as the Denon, it is a bit more balanced. It has a similar soundstage to the Denon, giving you a nice natural room filling sound. It is not a bassy as the Denon and cannot handle low sub bass as well but it does handle bass in a very natural sounding way, where the Denon was over bass heavy. For more bass I use the Outdoor mode and to me it sounds almost perfect. The only negative and possibly a "keep or return" issue for many is that the UBoom L does NOT come with the tuned firmware used in his original test/review/preview. It instead uses a standard Earfun firmware and it sounded very average as a result and I nearly returned it. Updating the firmware is overly difficult (I work in I.T. and still found it awkward). The firmware is not available on the Earfun site, you have also download a separate flashing tool also not on their site and also you have to use a USB-C data cable, not the usual USB-C charging cable that comes with speaker or most phones. After several failed attempts I eventually got the update to work using the USB-C cable that came with my son's Razer headset. Once updated it sounds SO MUCH better and now that it has been warmed it up a bit, playing music, it has gone from being meh to WOW. I expect it will get even better once it has been fully bedded in. Definitely a must buy based on this price and its performance but make sure you update the firmware or you will be disappointed.

Good sound and keeps running

I'm not very picky with audio quality but particularly enjoy bass, and this speaker is definitely the right one to go. Customer service is also helpful with any issues you may encounter (even though they may not solve it). I reached out about some cackling and lost audio output when switching between apps. It's most likely some firmware issue; they sent me a replacement as they could not figure out the issue which I am grateful for but it did not solve the issue at all. Felt bad as I now have two speakers that cackle randomly (sound and bass quality are still great). Now I'm experiencing high latency issues when watching videos/movies which bothers me as it doesn't sync with the speaker's lips on shows. Low latency mode is a thing but has a very annoying crackling sound. Overall an OK.. buy if you want a good bass speaker at a budget but not what you need for movies probably.

SIMPLY AWSOME THE BEST AT THE BEST PRICE! Forget JBL, forget Sonos, forget Bose; this little beauty outperforms all of them at half the price!!!!!

Great sound@great price!

Excellent speaker and for the price, you won't be disappointed in the slightest. The equaliser takes a little playing around with, to get the best solution for your own ear preferences and the specific situation/room/ambience you are using the speaker in. I have had it for about 1 week. It seems to hold all frequencies of sound and clarity of music/vocals extremely well over any volume from low to max. I have a few other speakers and I feel this trumps the other ones for all-round quality of sound and is much more attractively priced. Good bang for your buck. I like it that much, that I am going to buy a second one so that I can pair them. It doesn't have a powerbank (no biggy), but it has a built in mic which is amazingly helpful for taking calls handsfree and the other person can hear you very clearly. Can't comment on durability yet as I haven't dropped it, or had it playing outside in the heat for any length of time. However, it looks and feels like it is solidly and professionally constructed. You can hold it in your hand easily, it's not too heavy. However, it could do with a wriststrap just for added convenience. I prefer it in all respects (price, quality of sound, loudness, features) over my comparable market bracket JBL Flip 2 and JBL Charge 6 speakers.

El audio es muy bueno, se escucha mejor que otras bocinas del mismo precio. Lo mejor es que tiene aun entrada 3.5, la configuración de interior y exterior de Oluv's es una maravilla.

Fantastic little helper to the audio performance.

Ik gebruik de twee UBoom speakers in stereo modus als speaker set voor mijn Samsung the Serif TV. Ik wilde geen soundbar maar portable speakers voor mijn TV. Ik gebruik ze bij films. Voor normaal TV gebruik is het geluid van the Serif voldoende. De kwaliteit is super. Veel bas en helder weergave van de stemmen. Latency is minimaal. Voor weinig geld een enorme verbetering van geluidskwaliteit van mijn TV. Aanrader!
