The EarFun UBOOM L is a portable Bluetooth speaker designed for listening to music wherever you go. Its small and lightweight design makes it easy to carry around in your bag or backpack. It's even rated IP67 for dust and water resistance to help protect it against the elements. It doesn't come with as many sound enhancement features as more premium models; you can still switch between its Indoor and Outdoor sound modes as you move around, and its Video Mode helps reduce latency when you watch videos through your paired device.
Our Verdict
The EarFun UBOOM L is passable for music. Voices and lead instruments are present in the mix, though they lack some detail due to the roll-off in the treble range. Also, this smaller speaker doesn't bring a lot of punch or rumble in the bass, which is disappointing if you love bass-heavy genres like EDM and hip-hop. You can widen the speaker's sound with its Outdoor Mode, but it doesn't have more traditional bass or treble adjustments to customize its sound.
- Portable design.
- Clear reproduction of vocals.
- Few sound customization tools.
- Lacks low-bass.
The EarFun UBOOM L is middling for videos. You can pair up your smartphone to watch videos, and the speaker's Video Mode helps reduce latency to avoid lip-synching issues. It's not designed for movies, though, since it doesn't get very loud and doesn't reproduce a lot of low-bass.
- Video Mode to reduce latency.
- Not loud enough for larger spaces.
- Lacks low-bass.
The EarFun UBOOM L is okay for podcasts. Thanks to its balanced mids, voices are reproduced with clarity in the mix. They lack detail, though, due to the roll-off in the treble. Unfortunately, you don't have many sound customization tools to switch up its performance. It's loud enough for an average-sized room, though it struggles to fill up larger spaces with sound, so you might want to stereo pair a second unit if you prefer a louder sound.
- Portable design.
- Clear reproduction of vocals.
- Few sound customization tools.
- Not loud enough for larger spaces.
The EarFun UBOOM L doesn't have built-in voice assistant support. Instead, it uses the voice assistants from your paired smartphone. Overall, the speaker does a decent job picking up your commands when you're far away or in a noisier environment. It doesn't have as many features as speakers designed with voice assistant use in mind, though, so you can't mute its microphone, for example.
- Clear reproduction of vocals.
- Not loud enough for larger spaces.
- No built-in voice assistants.
The EarFun UBOOM L is acceptable for outdoor use. This small, lightweight speaker is incredibly portable, and its IP67 rating for dust and water resistance helps protect it against the elements. Its Outdoor Mode is also designed for listening in larger and more open spaces. This speaker doesn't get as loud as other models on the market, like the JBL Charge 5, and its battery life falls short of its advertised length.
- IP67 rating for dust and water resistance.
- Portable design.
- Few sound customization tools.
- Not loud enough for larger spaces.

Depending on your listening habits, you may prefer either the JBL Flip 6 or the EarFun UBOOM L. They're both portable Bluetooth speakers with similar designs but have different strengths. The JBL is better built, and its default sound is more even, which some users may prefer. It's more customizable, too, thanks to its graphic EQ. However, it doesn't support voice assistants like the EarFun.
The EarFun UBOOM L and the Anker Soundcore Boom 2 are both budget portable speakers. While the UBOOM has a lower retail price, the Anker offers a better price-to-performance ratio. They both have front-facing designs that limit their directivity, and they get equally loud, with similar degrees of compression at max volume. They're also similarly portable and well-built, though the Anker has a carrying handle to help you bring it around in one hand. The Anker has a more balanced sound profile and a much longer battery life, though, plus you can connect up to two devices simultaneously.
The JBL Charge 5 and the EarFun UBOOM L are similarly designed portable Bluetooth speakers. However, the JBL is the better pick overall. It's better built with a longer battery life and offers better sound quality with more rumble in the bass range. Also, its companion app gives you more control over its sound thanks to its graphic EQ. It has to downmix stereo sound into mono, unlike the EarFun.
The Anker Soundcore 3 and the EarFun UBOOM L are both portable Bluetooth speakers available for less. The Anker is the better of the two, as it has many more customization features, like a graphic EQ. Also, it has a longer-lasting battery life and a smaller size that may be more ideal for some users.
