Let the house rumble
One of the special features of the UBOOM® L is that EarFun turned to Olaf Lubanski, an Austrian music producer, to "tune" the speaker. Thanks to this, the musical experience offered by UBOOM® L stands out from the crowd of bluetooth speakers.

EarFun's innovative JumboBass™ technology guarantees powerful and clear bass. The passive diaphragms placed on the side of the speaker (essentially speakers without a motor) support the 55mm main drivers in amplifying deep sounds and achieving punchy bass sound.

Three modes
UBOOM® L can be used anywhere, in any conditions, as it can adapt to external conditions with its multiple sound modes.

One of the downsides of Bluetooth is latency. This is a problem if you use it to watch movies or videos with a Bluetooth speaker, because then the sound will not be in sync with the picture. Fortunately, EarFun has thought of that too, and you can enable video mode by double-pressing the Bluetooth button. In this mode, stereo sound is not available and the connection distance is also shorter, but in return, the image and sound will be in perfect synchronization, without noticeable slippage.

Outdoor mode boosts bass and higher frequencies to improve sound quality in noisier outdoor environments. In addition, the speaker broadcasts the music in a wider range, thus creating a real festival atmosphere. And in indoor mode, the speaker offers uncompromising, balanced, clear sound.

It lasts all day and water doesn't harm it either
The built-in 5200 mAh batteries allow up to 16 hours of music playback on a single charge. The 4 LEDs in the middle of the riser panel on top of the speaker indicate the battery charge, every 25 percent. If only one LED is blinking, we have less than 10% energy left. A full charge takes about four hours. The battery consumes 5V/3A. Uboom L can be fully used while charging.

The UBOOM® L portable speaker is washable and waterproof, and even saltwater resistant, so you don't have to worry even if you use it outdoors, in rainy weather, at sea or by the pool. Plus, it floats. So if you drop it in the pool, it will be on the surface in seconds.

Double dynamite
We are too used to the fact that bluetooth speakers can only play in mono, even though listening to music in stereo is the real thing. UBOOM® L also solves this problem. Pair two UBOOM® L speakers to enjoy your favorite tracks in stereo. In addition, this way you can double the power of the speaker and achieve a performance of 56 W.

Use
The USB-C charging port is on the back of the speaker, behind a waterproof rubber seal instead. Here is the 3.5 mm input, which allows you to connect the speaker to other sources. This part also has the factory reset button. It is important to note that while listening to music via cable, the speaker loses its water resistance.

UBOOM® L provides a stable and reliable Bluetooth connection and can be used from a distance of up to 15 meters. With the help of the built-in microphone and the hands-free function, it can even be used for hands-free conversations, so you can even conduct a video call or phone conversation with it.

On top of the speaker is a rubber-covered control panel with six buttons: power on, Bluetooth pairing, volume down, play/pause, volume up, sound modes. The microphone is also located here. In the active state, the LED above the power button lights up with a blue light. During Bluetooth pairing, the white LED above the second button will flash. And when outdoor mode is switched on, the LED above the last button lights up.
