Nobsound G3 Mini Bluetooth Digital Amplifier with Tone Control Review

The Nobsound G3 is a mini Bluetooth digital amplifier priced at $49.99. It packs a high-performance TPA3116 chip delivering 55W x 2, enough to drive most bookshelf and desktop speakers, making it an affordable upgrade for a home audio system.

Connectivity covers both worlds: Bluetooth 5.0 for wireless streaming with wide device compatibility - smartphones, tablets, PCs, TVs, CD players - and a wired RCA input, with a dedicated reset button for quick Bluetooth reconnection. The Pre-Out expands the system further: by connecting an active subwoofer or powered speakers, you can build a 2.1 channel setup and enjoy deeper bass without complicated wiring or extra gear. One caveat from Douk Audio: the banana speaker jacks and Pre-Out work simultaneously, and the volume, bass and treble adjustments apply to both outputs at the same time, so the sub cannot be trimmed separately.

Independent bass and treble controls let you add low-end warmth or vocal and high-frequency clarity to suit any music style or room. An easy-to-use select knob switches inputs, and an LED indicator shows the active input mode. Listed performance is 0.1% THD+N, 86dB or better SNR and a 20Hz-20kHz response within +/-1.5dB, running on DC 12-24V. The compact 90 x 105 x 30mm chassis fits home theater, desktop or small-space setups, and the box includes the Bluetooth antenna, a DC 19V power adapter and a user manual. There is no headphone output, so headphone listening needs a separate amp.
