LIELONGREN LLR055 USB Soundbar 2.0

The LIELONGREN LLR055 is a compact 2.0 channel USB soundbar delivering 8 W total power from dual drivers and a passive radiator. It targets desktop and laptop users who want louder, richer audio than built-in speakers without the clutter of a separate subwoofer or external power brick.

USB power and touch volume for tidy desks

A single USB cable carries both power and audio signal, so the bar needs no wall adapter and occupies only one port. Touch controls on the top surface handle volume changes, keeping the 2.2 in × 7.17 in × 1.81 in footprint free of protruding knobs. The 3.8 ft cable reaches rear ports on most monitors or towers.

Steps up from basic 6 W bars and monitor speakers

Compared with typical 6 W (2 × 3 W) models, this unit moves to 8 W (2 × 4 W) drivers and larger 1.8 in cones for extra headroom and lower distortion. Buyers who need room-filling volume, deep sub-bass extension, wireless streaming or multi-device switching will find those needs unmet by this design.

Questions about this item

How loud does the 8 W soundbar get before distortion becomes noticeable during long sessions?

The unit is rated at 8 W total power with dual 4 W drivers and a passive radiator; the supplier describes the output as extra loud with lower distortion.

Does the USB-powered speaker heat up or make fan noise when it runs all day?

It draws 5 V DC from the USB port with no internal fan, so heat and noise are minimal during extended use.

What device and port must I already have to use this soundbar?

A Windows, macOS or Chrome OS computer with a free USB-A port supplies both power and audio — no extra cables or adapters required.
