Nobsound Q10 Bluetooth 5.0 Digital Amplifier with AUX and Optical Inputs, 100W

Our verdict

The Nobsound Q10 is a $36.99 micro amplifier that punches well above its 116g weight on paper: a TPA3221 Class D chip rated at 100W+100W, distortion below 0.001%, and three inputs (Bluetooth 5.0, 3.5mm AUX and optical) with matching cables included. The front volume display and single multifunction knob keep it simple. If you want the full output promise, buy the version with the 19V/4.74A supply or provide your own beefy DC 9-24V adapter.

The Nobsound Q10 is a mini stereo power amplifier priced at $36.99 for small listening spaces such as a desk, bedroom or workshop. It measures just 77 x 22 x 62mm and weighs 116g, yet houses a TPA3221 Class D amplifier chip rated to output up to 100W per channel with THD below 0.001%, and it drives speakers through banana jacks.

Input flexibility is unusual at this price. There are three input modes: Bluetooth 5.0, 3.5mm AUX and optical, and the box includes a 3.5mm AUX cable, an RCA cable and an optical cable. The Bluetooth 5.0 chip is rated for low latency and up to 50ft of transmission distance, which covers phones, tablets, TVs and CD players. Control is deliberately minimal: a single knob powers the amp on and off with a short press, switches inputs with a long press, and sets volume when rotated. Input indicators and a volume display show the working state at a glance.

On the power side, the Q10 accepts a DC 9-24V wide input range, so it can run at home or on the road. The optional 19V/4.74A adapter is the recommended pairing; if you choose the version without a power supply, Douk Audio suggests a larger supply of your own for higher output. Rated frequency response is 20Hz-20kHz within plus or minus 3dB, SNR is above 89dB, and complete protection circuits are built in. One housekeeping note: the front display panel ships with a thin protective film, which you can peel off if it looks scratched.

Douk Audio ships worldwide with free and expedited options, and the cost varies by destination country. Packages under 2kg go by airmail (10-25 days); heavier orders ship via DHL, UPS or FedEx (5-8 days). Import duties or customs charges are the buyer's responsibility. The store offers a 30-day free return or full refund and a 1-year warranty on all items, excluding orders placed by mistake, man-made damage or misuse, subjective change of mind, and anything outside the warranty terms.

What we liked

  • Big output for a 116g box: the TPA3221 Class D chip is rated at up to 100W per channel with distortion below 0.001%
  • Three input types, and the 3.5mm AUX, RCA and optical cables all come in the box
  • Bluetooth 5.0 chip with low latency and up to 50ft transmission range
  • One knob runs everything: short press for power, long press to switch Bluetooth/AUX/Optical, rotate for volume
  • DC 9-24V wide input voltage with full protection circuits; equally at home on a desk or on the road

Worth noting

  • The version without a power adapter needs your own DC 9-24V supply; Douk Audio recommends 19V/4.74A for higher output
  • The 100W-per-channel figure is a maximum rating that depends on delivering enough supply voltage and current
  • Banana speaker jacks only, so you need banana plugs or bare-wire speaker cables

Questions before you buy

How do I switch between Bluetooth, AUX and optical?

Long press the single knob to cycle inputs; a short press powers the amp on or off, and rotating the knob adjusts volume.

What cables are in the box?
