EarFun UBOOM L is a portable Bluetooth speaker aimed at users looking for balanced sound, decent performance, and high durability in a compact body. The manufacturer has bet on its own JumboBass™ technology, a pair of 55 mm drivers, and passive radiators on the sides—so the speaker has ambitions to compete even with more expensive models. It’s also impressive thanks to the IP67 certification, up to 16 hours of battery life, and the option to stereo pair two units.

JumboBass™ and hardware: 2 × 55 mm drivers plus passive radiators
The sound is built on 2 × 55 mm dynamic drivers with a total output of 2 × 14 W, complemented by the side passive radiators. These help enhance low frequencies without causing significant distortion. The JumboBass™ technology works with a dedicated DSP processor and multiple dynamic range controllers to boost bass while keeping vocals clear.
In practice, that means a fuller sound at both low and mid volumes. Based on user reviews, the sound is more neutral than “effectively bass-boosted,” which will appeal to anyone who prefers a more natural character. For everyday listening indoors or on the terrace, the speaker has enough power—and extra headroom—even for a smaller get-together.
Sound modes and stereo pairing
The speaker offers three sound modes—Indoor, Outdoor, and Video Mode. Switching changes the EQ character and the width of the soundstage depending on your environment. For example, the Outdoor mode boosts projection into the space, while Indoor is better suited for smaller rooms.
If one unit isn’t enough, you can pair two speakers into stereo mode (TWS). In that case, you’ll get a wider soundstage and noticeably higher volume. For a garden party or a larger space, it’s an interesting option that takes the EarFun UBOOM L to a higher tier.
IP67, floats on water, lasts 16 hours
Durability is one of its strongest points. The IP67 certification means protection against dust and immersion in water. The speaker is also designed to float, so if it falls into a pool, it shouldn’t go to the bottom. So it’s great for water, the beach, or camping.
Inside, there’s a battery with a capacity of 7,4 V / 2 × 2600 mAh (total 5200 mAh), delivering up to 16 hours of playback depending on volume and content type. Charging is via USB-C and takes about 4 hours. There’s also a 3.5 mm AUX input for wired connections.
Hands-free calling and Bluetooth 5.0
There’s also a hands-free calling function thanks to the built-in microphone. Supported profiles include A2DP, AVRCP, HFP, and HSP. The wireless connection is provided by Bluetooth 5.0 with a range of up to 15 meters in line of sight.
The speaker dimensions are 210 × 78 × 72 mm and the weight is approximately 650 g, so it’s still a fairly compact device that’s suitable for a backpack. The build feels solid and the design is ready for frequent carrying.
