    Excellent speaker with good low end and clarity
    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.

    Great speaker – superb value
    Not the loudest but great audio quality. Oluv tuning really makes the speaker sound wonderful. Can’t beat the price and quality. I think it sounds better than models that cost more. Good battery life. Connects to phone quickly. Solid build. Doesn’t have a travel case which frustrating.You make a sacrifice for sound loudness and quality, so this model goes loud but not as loud as some similar models that sound worse.

    Speaker with versatile Indoor/Outdoor tuning. Tuned by Oluv.
    EDIT: I’ve slightly updated this review, because I ended up purchasing another speaker for stereo sound.I own two of the original UBOOM’s. This new larger UBOOM L has a different form factor and sounds much better tuned by Oluv. Keep in mind everyone’s ear is different. My ear wants bass, but I don’t want bass that is boomy and that takes away from overall clarity.Oluv’s tuning does two things in my opinion. Indoor Mode allows you to listen in your home and even at very low levels. You won’t disturb your neighbors in an apartment setting and you can still enjoy full and balanced sound at lower volume settings.The bass is there, but it’s not boomy bass. Maybe a bass head won’t like that? Personally, I’m not a fan of boomy bass that overwhelms the clarity of the music. If you want a little more bass, Outdoor Mode is the way to go. There’s more bass in that mode, but still tuned so it doesn’t overwhelm everything.Oluv gave people choices here, which I like. I see myself using both modes, when it’s appropriate in my environment and still have balanced tuning either way at any volume level.I ended up purchasing two of these speakers for stereo sound. There’s plenty of volume with one speaker, but the L/R stereo separation playing two together is so worth it in my opinion. Overall this an excellent speaker, at a great price point. The UBOOM L gives you the performance and sound of much more costly speakers. There are plenty of Bluetooth speakers released without much thought to tuning. Some have too much bass and others too much treble. This tuning is balanced and neutral. I like that Oluv collaborated with Earfun. I hope he does more of this in the future.In regards to the firmware. It can be found at Earfun’s website under Support/Product Guides, then click on UBOOM L. Just download the media product tool, firmware and instructions. It’s pretty straightforward. Just make sure you have a USB-C data cable. Less than a minute to run the update. After the update, forget the device in your Bluetooth settings and reconnect.I’ve attached photos and a video clip of the speakers connected in Stereo playing a track from the Spotify playlist of NCS/NoCopyrightSounds. They’re playing in Indoor Mode. Please use your headphone’s or ear bud’s to listen. (If you listen with a mobile device or tablet, you won’t get the full effect). You can hear the combination of clarity, bass and stereo separation in the video. I hope this video helps. I would definitely recommend giving this speaker a try.Music / NoCopyrightSounds:“Slow Down” by Jim Yosef, Shiah Maisel

    Good for around $50, if more than $50 – consider buying something else.
    Good for around $50, if more than $50 – consider buying something else.Sound is good. Came with firmware 0.50. It sounded good. Tried 0.43, 0.48 – they sound a little bit different. Can not say that 0.4x sound better. 0.50 has more bass, sounds louder. Volume is more than enough for home use.Battery lasts around 10 hours using medium volume.It has a strong plastic smell that does not go away even month later.Connecting to devices is not easy as I would like it to be – sometimes it does not work or takes some time to connect. Using multiple devices (one after another) also does not work flawlessly – sometimes you need to “forget” it on previous device for it to connect to new device or reset the Speaker.Without “video” mode ON there is a significant delay – not good for video watching, PC use or similar.With “video” mode ON it is OK to watch video or use with PC.Sometimes it may randomly produce cracking sound – not sure why. With “video” mode ON it happens even more often.Overall it is a good speaker (for $50).

    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.

    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)

    Après beaucoup d’hésitations, j’ai choisi de prendre cette enceinte. Après tout je pourrais toujours la renvoyer si elle ne convenait pas… La qualité sonore est vraiment agréable. Les divers instruments sont bien identifiables. Certes les graves sont un peu mis en avant, mais pas de manière exagérée. Cet équilibre rend cette enceinte vraiment agréable pour du rock, du jazz et de la musique classique. L’écoute n’est pas fatigante.La batterie semble avoir une très bonne autonomie. Le bluetooth se connecte sans souci et porte au moins jusqu’à 8m malgré la présence de 3 cloisons.Bref, elle fait largement ce qu’on en attend et ne coûte pas trop cher.
