ETECH USB Sound Bar Bluetooth 5.0

The ETECH USB Sound Bar is a wired computer speaker that connects through USB power and offers both Bluetooth 5.0 and 3.5mm auxiliary inputs. It uses four speaker units plus two independent bass diaphragms with neodymium magnets and mica fibre diaphragms. A single volume knob controls power and level.

Suits desks needing simple stereo

This sound bar suits users who want a compact USB-powered speaker for a desktop, laptop, phone, tablet or console with either wireless or wired playback. It is not for buyers who require a built-in battery for portable use, a separate subwoofer output, or additional digital inputs such as optical or HDMI.

Bluetooth 5.0 and 3.5mm aux connectivity

The deciding specification is the dual connection method: Bluetooth 5.0 for wireless streaming and a 3.5mm aux jack for wired sources. Both feed the same six-driver array through the single USB power connection. Choose this model only if those two interfaces match your source devices.

Questions about this item

How do I power and connect the ETECH USB Sound Bar to my computer?

Plug the USB connector into any USB port for power, then pair via Bluetooth 5.0 or plug a 3.5 mm auxiliary cable into the aux input; press the volume knob twice quickly to switch between the two modes.

What upkeep will the speaker drivers and diaphragms need over time?

The four neodymium-magnet drivers and two mica-fibre bass diaphragms have no user-serviceable parts; occasional dusting of the grilles with a soft brush is the only maintenance required.

What limits how loud I can play the sound bar continuously?

Because the unit draws all power from the USB port, maximum sustained volume is constrained by the port’s current supply; if the port cannot deliver enough current, output will compress or the speaker may shut down.
