    What I like:Great soundBluetooth 5.0Driver layoutBuild qualityUSB CVideo modeIndoor/Outdoor modesip67 ratingWhat I don’t like:No app supportNo carrying strapFirmware update can be trickyThe EarFun UBoom L has became one of my new favorite speakers . I am so glad EarFun finally made another speaker. The company was definitely lacking another speaker since the EarFun go was discontinued and the original UBoom is now three years old. It was definitely time for a new speaker from such a great company that produces great sounding earbuds that I love and always have a set on me for daily listening. When I first found out about this speaker and discovered it was tuned my the great Olaf from Oluvs gadgets I knew I had to own one. When the speaker arrived to me it came in a JBL style box and inside you will find the speaker, and owners manual and a USB c cable. I immediately took the speaker out of the box and after several attempts and a replacement speaker, I was able to update the firmware on my original speaker. The speaker looks great and has a great layout and design, it reminds me of a center channel you would have in a 5.1 sound system at your home. The only disappointment I have is I wish it had a lanyard or carrying strap since this speaker doesn’t weigh as much as my JBL Charge 4. On the top you will find a power button, Bluetooth button, minus button, multifunction button, plus button and, indoor/outdoor button and battery indicator lights. On the back of the speaker you will find a rubber flap which protects the usb c charging port and aux in port and on the sides of the speaker is where you will find two JBL style passive radiators and on the front you will find a mesh grill with the EarFun logo and under is two 55 millimeter 14 watt drivers which together produce 28 watts total power which is 4 watts more than the original uBoom which only produced 24 watts total power it also has a 16 hour battery life. Now let’s move on to how it sounds. After several hours of listening to this speaker I have to say I’m impressed. The treble, mids and, lows all sound natural not overbearing on indoor mode and when you switch to outdoor mode, you get a boost in all aspects with bass, mids and, highs. Everything sounds crisp although I believe tweeters could have assisted with off axis listening and the sound dispersion. Olaf nailed it with being able to listen on any aspect and get the same result with sound. Phone calls are also clear on this speaker, the built in mic does a great job picking up my voice on phone calls and accessing Siri or google assistant. Overall I am impressed with this speaker, just wish they had some tweeters or app support with EQ settings you can toggle such as Oluv Signature tuning, Bass boost, custom EQ.

    5.0 out of 5 stars Speaker with versatile Indoor/Outdoor tuning. Tuned by Oluv.
    Reviewed in the United States on July 12, 2022
    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.

    5.0 out of 5 stars Super Sound und gutes Akku!
    Reviewed in Germany on August 14, 2022
    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)
