Review: Perfect for holidays and camping. - 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.
Review: Almost a great speaker but… (6 months on) - 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.

### ⭐⭐⭐⭐⭐ Brilliant sound for its size—perfect camper van companion!
*by R***O on 18 May 2026*

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.
