EarFun Bluetooth Speaker, UBOOM L Portable Speaker 28W Loud Stereo Sound, Rich Bass, IP67 Waterproof & Dustproof, Dual Pairing, Built-in Mic, Low Latency, Wireless Speaker for Party, Indoor & Outdoor

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.

I did a fair amount of research before plumping for the Earfun L for £56. At Peter Jones & at Currys I listened to various devices, including the Flip 6 (£74) and JVC XSD5212A (£69). The Flip 6 should have won hands down as its 190 grams lighter, has 2W more power. Yet to my untrained ear it sounded too bright. One device that did sound better on Austrian tuner Olaf Lubanski's youtube samples is the Bose Soundlike Flex (£149), which has a fuller, pleasant bass sound. The Earfun L seemed to me to offer the best value. Amazon prime delivered within 24 hours, and I was excited to fire it up. It sounds pretty darn good! At first I tuned to the outdoor setting, but by morning I was preferring the indoor tuning. The device was delivered with the 0.50 tuning rather than Olaf Lubanski's 0.45 tuning I am happy with the sound at the supplied setting, but I will use software to revert to Olaf's critically acclaimed 0.45 setting. Bravo Earfun L for marketing a decent-sounding speaker at a fair price! I would be highly skeptical of the 16 hour battery life, which the manual describes as dependent upon both volume level and audio content. A new speaker battery may indeed last for 16 hours if playing jazz or classical music at low volume. At higher volumes the battery life is likely to be considerably less, and the more times you recharge, the less efficient the battery becomes. I guess we all know this from experience with our mobile phones. If you can pick one of these beauties up for £56 I don't think you'll go far wrong.

Bought after seeing Oluv’s recommendation and have not been disappointed. Firmware upgrade did fail initially but discovered a USB-C to USB-C cable worked. A failed firmware update does not brick the unit, but I recommend using a USB-C equipped PC, USB-C to USB-A cables would not work for me. As for sound remember any speaker needs some “burn-in”, some bass heavy signal to loosen up the speaker suspension. Also speaker position in the room makes a huge difference to bass response. If you have hard floors try sticking the speaker on the floor in the room corner to enhance bass. For me the clarity in these speakers is amazing for the price. Like many have said, very smooth and detailed. The bass appears a little lean with “indoor” mode, but I’d rather have the midrange clarity. If you want more bass I’d suggest an app based eq. After a couple of weeks with one unit I was convinced to get a second unit for stereo. Big improvement in sound with proper left right separation and better bass. Well worth it. Edit After a couple more weeks these speakers do bed in and improve. Bass is getting better too. Placed on a hard floor in the room corner there is ample bass response in “indoor mode”. No need for any EQ app. Also discovered you can stand them on end either side of your laptop for a very clear nearfield monitor like setup. Finally I am very impressed how a pair remember stereo mode. If you turn a stereo pair off then on again, it remembers the stereo settings and re-pairs. I had an expensive pair of mini rig speakers that always had trouble with stereo mode constantly dropping. These speakers are much more reliable.

All good so far, this is my garage/workshop speaker and it connects seamlessly, does the job nicely. I read about fancy firmware etc, couldn't get any of that to download, and the app doesn't support this model, but don't let that put you off, it just works straight out of the box.

Overall this is a powerful and handy speaker to have in such a compact size. I use it happily at home, travel and camping etc. There are many reasons to love it including long battery life, fully waterproof and excellent sound for such a small speaker, but my unit has bluetooth connectivity issues that are infuriating. If I'm connected on macbook pro, sometimes I can't connect with phone. I have to forget all devices and restart the process. Same goes when other people try connect. It is unfindable unless device is removed completely. Earfun have acknowledged that and are working on the problem. Would also like to suggest a strap attachment be added as this as it's bit clumsy. In addtion, the buttons can be hard to navigate in the dark. I often attempt to press the lower volume button but hit the bluetooth button instead. Perhaps the placement of these buttons could be wider apart or volume placed on the far sides instead of next to play button. Not distinguished enough. Would also like to add that I too had to find someone else's PC to download the firmware software to backdate the firmware to a better sound from Oluv. The Earfun firmware out of the box is too shaped and distorts at volume, but with Oluv's version the speaker is clear and well tuned with no distortion at any level, plus the boost button improves the bass a lot. Despite these shortcomings this speaker has a great sound with passive bass that does a great job when placed close to a wall and travels wide in comparison to a direct speaker like anker soundcore boost which must be listened to head on so to speak. Great!

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.

Having owned several branded Bluetooth speakers over the years, JBL, Sonos to name a few I was looking for something small, reasonably lightweight for traveling. After reading many reviews about the earfun speaker having audiophile quality I thought at £60 it's worth a shot. Well after a few tweaks and down grading the firmware (note the supplied cable didn't work for this). This little speaker certainly packs a punch, would I say it's audiophile quality? Not quite but it's close. If your looking for a small compact Bluetooth speaker that's convient for traveling and don't want to compromise the sound. This ticks all the boxes. Oh and it can be paired with another for stereo sound (not tried) but certainly considering another purchase to test this out
