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

Overall great package. Directly competing with the Tribit and JBL flip 6. Good Build Quality. I did not expect the sound quality of this product will be this good. Very Premium sounding speaker. Goes very loud. But the only issue is when you ramp up the volume to it’s Max (100%), the bass becomes thin, the trebles and the mids kick in. But there is no distortion at all at any volume, even at 100%. It would have been nice, if there is App support for this speaker. Very happy with this purchase. Had to exchange the product because I received a damaged and defective piece. The battery life is also satisfactory. Can play upto 12 hours at 80% volume. The sound is crystal clear, crisp and sharp. Enjoying alot. Updating the Review after 3 months of usage. Had to replace the Product because of receiving a damaged product and firmware couldn’t be updated. After the exchange, I could update the firmware to Oluv’s Tuning. I recommend every one to use the Oluv’s tuning. The stock tuning is not good. But the increase of volume levels in stock tuning is very good. The overall Loudness, Bass, Treble balance is good in Oluv’s tuning. Oluv is an Audio Producer who has great emphasis on sound and audio products.

15 days of experience: im very particular/moody abt bass n mid & highs. I was to buy tribit stormbox as soundcore neo was not availablefor months.. i Dont care if they lack 10% in over all performance. However, in case of boom L , they have been tuned perfectly to give good bass (in in low volumes, u wud not regret) n perfecy vocal sound too. One thing to highlight is that normally su h speakers spread their sound in one direction and buys prefer 360 sound. This speaker impressed me as its sound filled the rooms wth bass and sound that can be heard from another room, tht too with good quality. It lacks auto shut features which is required especially when u have been given decent but not extra battery backup. If you ud like it to use for party with 15 to 20 people in a room then one speaker will hive you good output(just keep it to ear level so sound spreads well in room).. other wise to have bombastic sound buy another one which will surely give you surround and stereo sound . I m happy to get one but disappointed to see rates going up in past 15 days twotimes which prevented me to buy another. I think it iverall performance credits goes to tuning technology that keeps bass and vocals in balance throughout the sound level. 👌🏻 this is best n cheap competition to jbl n soundcore anker speakers and portable enogh ti carry anywhere without worry of damage by water n dust. You will surely love show off these spkrs to ur frnds n family. So go ahead n buy them to test first as company claims to accept spkr back unconditionally in a month if u dont like. So take test it. But wait untill this product come back to 5000 range again.

It's having so amazing sound with this price . Non other brand can't supply with such sound quality even redmi. Thumping bass , hd sound , battery back up & 360° sound spred out . It doesn't have sound distortion upto 100° vollum .But the model is now terminated .

After 7 days of research in reddit, YouTube I finally ordered this. My other choices were: 1) Jbl flip 6 (at 7.5k) 2) Tribit stormbox 2 (6k) 3) This (5k) In all YouTube comparisons video this sounded better than jbl flip 6(smoother treble) and way better than tribit despite being low price. Also reddit were full of positive reviews of this speaker. After ordering I was truly impressed. -The bass and sound stage is separate. -Vocals and other instruments aren't overpowered by bass. -Treble is quite smooth. -Sound is quite loud. Has an app. download it. People will tell to use oluvs eq. But I liked the "More treble 3" eq setting.

Don't buy anyone this product you regret and return the item. Don't waste time and money in this

Audio quality is a mixed bag for me. The company has messed up with software veraions where latest versions do not sound as good as older ones. So one has to go through the tedious and unnecessary process of downgrading. Even after downgrading, sound quality is not consistent for me.

Worth the money if you can flash oluv's firmware 😉

Nice speaker out there. Best customisable as per your needs. You need to work somewhat for best experience and taste. It is good out of the box, but will be best with earfun app with all modes. Update firmware to 1.2.7 for app support. Don't go for .4 oliv etc , as you can get by click of button in the app.

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
