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.

Sorprende la cantidad y sobretodo la calidad y naturalidad del sonido en un dispositivo tan compacto.

Latency when watching video is too high, even with the video mode enabled. Sound is ok but not great. Low on bass and general crispness of the sound. Volume controls directly control your devices audio, which i dont like because i cant control the sound volume as finely as id like. Ok build quality, ok price. Got this one because reviews where good. I do not agree and will not get a second unit as planned to try the stereo function.

This is an excellent Bluetooth speaker if you are looking for a Bose-type replacement at a great price. I had the original generation Bose SoundLink, but it became a paperweight due to the battery no longer holding charge (and not working off a cable either). This Earfun UBoom L has a similar sound profile at lower volumes, offers great Bluetooth connectivity, and has clear, believable sound listening in small spaces or at low or moderate volumes. I'm not a sound engineer or audio expert, but from my interest in stereo and guitar equipment, I became aware of something called the Fletcher-Munson Effect. Basically, the human ear is more sensitive to mid-range frequencies (roughly between 2kHz and 5kHz). This means that lower volumes, the sound you are perceive will seem to have less bass than if the same EQ were applied at a louder volume. As a result, manufacturers of small-format speakers figured out that you need to boost certain frequencies at low volumes and generally reshape the EQ for your ears to perceive what would be a "flat" setting at a louder volume. Bose was a pioneer in popularizing this concept, but it's widely used in all types of affordable Bluetooth speakers, and the UBoom L is a great example of that. It sounds great out of the box, but with a phone app, you can apply special indoor and outdoor EQ settings from a sound engineer named "Oluv". If you're like me and frequently use Bluetooth speakers to play background music at very low volumes (while working, studying, or just for general ambience), then you'll appreciate this. There was a whole "Beats vs. Bose" thing about 15 years ago where people became obsessed with having as much bass as possible. Similar to a Bose unit, the UBoom L has plenty of low end, but with the Oluv EQ, it retains clarity and does not overwhelm the other frequencies. I will say that there is plenty of low end in this speaker, and there are presets and custom EQ's you can play with if you prefer a bassier sound. The internal battery charges with a USB-C cable, and I appreciated that they included an AUX jack. Some of these speakers are great to use with other audio equipment and instruments that either do not have Bluetooth, or would suffer from latency. There are plenty of great budget and premium Bluetooth speaker options nowadays, but this is a great all-around product. UPDATE (08/20/25): Need to make a slight correction to my review above - the UBoom L has a significant latency (audio delay between input and sound playing through speaker) when using the AUX 3.5mm jack. Apparently, this is a common issue not just with the Earfun units, specifically, but with most Bluetooth speakers that use any type of digital processing or EQ to produce sound. The latency is significant - around 250 milliseconds, I believe - which is far too large to use it effectively to play sound from any instrument. However, since this is a very "niche" use of this otherwise excellent Bluetooth speaker, I am not downgrading my review score.

Ich habe den Lautsprecher seit ca. 1 Monat und war so damit zufrieden das ich nach zwei Wochen mir noch einen besorgt habe (vor allem um Stereo/Party Modus im Garten zu Nutzen)! Der Lautsprecher ich sehr gut Verarbeitet und fühlt sich in der Hand sehr solide an. Es ist vielleicht nicht der Hingucker, aber es soll ja klingen und nicht aussehen! Es ist bis jetzt der grösster BT Lautsprecher in meiner kollektion (ich habe einen JBL und einen Denon) und er ist definitiv zu gross um Ihn einfach so mal in die Tasche zu werfen und überall mitnehmen, aber bei solchem Klang und Lautstärke ist es verständlich. Die größe entspricht ungefähr einer 1L Flasche - auf dem Fotos ist ein normales Feuerzeug als referenz. Die größe hat auch vorteile - die Lautstärke (dazu komme ich später) und die Laufzeit. Mit einer voll geladenem Akku hat bei mir der Lautsprecher 3 Parties durchgehalten (ca. 15 Stunden insgesamt). Der Lautsprecher wird mit USB-C geladen und in 3-4 Stunden wird das Akku voll. Die Bluetooth Verbindung ist sehr Stabil und die Reichweite ist gut genug für einen grossen Garten (Sehe Video Test#1). Einziges "aber" ist die Reichweite beim Stereo-Modus, und zwar nicht die Reichweite zwischen den Lautsprechern und dem Handy sondern die Reichweite zwischen den zwei Lautsprechern! Meine Idee war es die Zwei Lautsprecher an verschiedenen Seiten des Gartens zu platzieren und damit gute Lautstärke überall zu haben, aber dieses geht leider nicht weil, wenn die zwei Lautsprecher mehr als 5m getrennt sind bricht die wiedergabe auf beiden Lautsprechern. Dieses Verhalten ist gut auf meinen Video zu sehen im Test#2. Im Dual-Modus sollten die Lautsprecher also nicht weit auseinander sein - in meinem Fall habe ich beide auf einem Tisch in der Mitte des Gartens in gegenüberliegende Seiten gedreht, so das der Sound in beide Richtungen geht. Das wichtigste an einem Lautsprecher ist aber der Sound und der ist in diesem Fall sehr gut! Das Gerät verfügt über zwei einstellunge - Indoor und Outdoor. Im Indoor modus ist der Klang sehr dynamisch - der Bass ist voll und kräftig und die hohen töne sehr klar und akzentuiert. Wenns um den Klang geht kann der Earfun lautsprecher ohne Probleme mit deutlich teureren Lautsprechern verglichen werden - mein Denon klingt nicht besser als dieser Gerät. Die Lautstärke ist mehr als genügend für ein Wohnzimmer. Im Outdoor Modus wird die Lautstärke höher und der Bass wird noch Kräftiger. Auf der ganzen Lautstärke Skala klingt der Lautsprecher gut - sowohl auf der niedrigsten wie auch höchsten Stufe gibt es keine unangenehmen Verzerrungen. Ich kann persönlich den Lautsprecher nur empfehlen - er klingt wie eine höhere Preisklasse und hat keine größeren Mängel (wenn man die Größe oder Stereo-Reichweite nicht als höchste prio sieht)

Great product, no complaints
