Nobsound NS-10G PRO Mini Bluetooth 5.0 Digital Amplifier with DSP

Our verdict

The NS-10G PRO is the upgraded take on Nobsound's popular mini amp: a TPA3221 chip rated at 100W x 2, Bluetooth 5.0 with EDR and DSP reaching 15m, and a purist twist in the removal of the volume knob for a quieter signal path. Gold-plated binding posts and five color choices finish the package at $39.99. Plan on the optional 12V/5A supply or your own DC 9-24V / 3A adapter, and control volume from your phone or source.

Best for
Minimalist desktop listeners who want a tiny, quiet, knob-free amp for Bluetooth or AUX sources and modest speakers.
Skip if
You want an onboard volume knob, a headphone jack, or the highest power from the smallest included bundle.

The Nobsound NS-10G PRO is a mini Bluetooth digital amplifier priced at $39.99, and it is the newest update of the popular NS-10G, repositioned for better performance and purer hi-fi sound. Its footprint is tiny at 78 x 70 x 23mm, small enough to hold in one hand, and it weighs 240g without the power supply.

The upgrade centers on power and purity. Where previous mini amps asked a lot of modest chips, the NS-10G PRO uses a Texas Instruments TPA3221 rated at 100W x 2, which Douk Audio says will amaze relative to its size. To keep the circuit clean, the design removes unnecessary functions like the volume control, shortening the signal trace and eliminating the noise floor entirely. Bluetooth moves to 5.0 with EDR and DSP, improving both sound quality and distance, now 15m rather than the older version's 10m. A useful side effect: the upgrade version also drops the prompt tone for quieter operation.

Connections are Bluetooth and AUX in, with upgraded gold-plated copper binding posts for the speakers to resist corrosion and maintain transmission quality over time. Compatibility spans smartphones, TVs, iPods, iPhones, iPads, computers, tablets, CD players and MP3 players, with one exception: the amp is not suited for calls. The unit runs on DC 9V-24V at 3A or above, with a 12V/5A power supply available as an option, and comes in black, silver, gold, blue or red.

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

  • Upgraded TPA3221 chip lifts rated output to 100W x 2 in a case you can hold in one hand
  • Bluetooth 5.0 + EDR + DSP improves both sound quality and range, now 15m versus the older 10m version
  • No volume knob by design: removing it purifies the circuit and shortens the signal trace for a lower noise floor
  • Upgraded gold-plated copper binding posts resist corrosion and keep transmission quality high over years of use
  • Five finish colors (black, silver, gold, blue, red) and super-broad device compatibility round out the value

Worth noting

  • Volume must be controlled at the source device, since the amplifier has no volume control of its own
  • Full rated power needs a supply of DC 9-24V at 3A or above; the 12V/5A adapter is optional and not in the base bundle
  • There is no headphone output or optical input, and Douk Audio notes it is not suited for calls

Questions before you buy

Why does the NS-10G PRO have no volume control?

Removing the volume knob purifies the circuit and shortens the signal path, which Douk Audio says results in no noise floor. Volume is set on your phone, computer or other source.

Bluetooth 5.0 with EDR and DSP is rated for a 15m distance, improved from the older version's 10m.

What power supply does it need?

DC 9V-24V at 3A or above. A 12V/5A power supply is available as an optional extra, and there are variants with and without a supply.

What is the return and warranty policy?

Douk Audio offers a 30-day free return or full refund and a 1-year warranty. Exclusions include orders placed by mistake, man-made damage or misuse, and subjective change of mind.
