Portable Tan Speaker with Twist-Open Chamber

The Go-Rock TRMS02MA is a compact wired speaker finished in tan. It connects to phones, laptops and other devices through a standard 3.5 mm plug. The twist-open design expands an internal acoustic chamber to enrich audio output. A built-in rechargeable lithium battery powers the integrated amplifier for portable use.

Wired 3.5 mm Connection and USB Charging

Audio travels over an analog 3.5 mm cable so no wireless pairing is required. The speaker draws operating power from its internal battery rather than the host device. Recharging uses the supplied USB cable and any standard USB port. Both the audio cable and charge cable retract into the body to avoid tangled cords.

Battery-Powered Amplifier for Personal Listening

The frequency-tuned amplifier drives the expanded chamber for clearer sound at modest volumes. Battery life covers several hours of playback before a USB recharge is needed. The single-driver design suits desktop or travel use for one listener. It does not replace a multi-speaker system for room-filling sound or deep bass extension.
