Nobsound Q10 Bluetooth Amplifier 100W Review
A palm-sized 116g Class D power amp with a TPA3221 chip rated at 100W per channel, Bluetooth 5.0 plus AUX and optical inputs, and all three cables included. One knob handles power, input switching and volume.
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.
- Best for
- Anyone building a compact desk or bookshelf system who wants a cheap, flexible mini amp with Bluetooth, AUX and optical inputs.
- Skip if
- You want a power adapter included at the base price, or you need a headphone output.
Why 3.5/5: The page gives chip, input range, weights, a packing list with three cables and a one-knob control scheme for $36.99. Held back by a supply that is optional, a 100W rating and a THD claim with no conditions, an S/N ratio of only above 89dB and dimensions that conflict.
Weighing it up? Douk Audio Class D Amplifiers Compared: Q10, A5 PRO, NS-13G MAX, NS-14G PRO and G7
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.

How it compares
Apart from the Nobsound M5.1 5.1 Channel Home Theatre Amp review's 5.1 amp, the Q10 is the only amp in this type whose page lists an optical input. Among the TPA3221 amps, the Nobsound NS-01G MAX Amplifier 100W+100W review ($39.99, $3.00 more) swaps optical for a 3.5mm PRE OUT and states both its own adapter's output (30W+30W) and the 100W+100W ceiling (under 24V at 8A); the Q10 page gives neither. The Nobsound TA-21 Bluetooth DSP Amplifier review ($46.99, $10.00 more) lists 100W+100W, Bluetooth with DSP and AUX but no optical, and an 80Hz-20KHz response against the Q10's 20Hz-20kHz (±3dB).
At $36.99, the Without Power Supply option, the Q10 undercuts both and is the lighter box: 116g against 240g for the NS-01G MAX and 143g for the TA-21; with its optional 19V supply it is $47.99, dearer than either. It suits a desk or TV setup where an optical feed from a TV or console is the main source and you will bring a 19V or larger adapter; skip it if you want a headphone output or an adapter in the box at the base price.
Shipping, returns and warranty
- Shipping: Douk Audio's current shipping page says orders are generally processed no later than the next business day and arrive in 2-8 business days, with duties, taxes and customs fees included in the checkout price unless noted otherwise.
- Older shipping terms are still online: airmail at 10-25 days for parcels under 2 kg, DHL, UPS or FedEx at 5-8 days above that, and a line saying the store is not responsible for import duties. Check the delivery estimate and any duties at checkout.
- Returns: ask within 30 days of delivery and wait for approval before sending anything; an approved return has to ship within 7 days. Items need all packaging and accessories and no excessive wear, or the store can refuse them or refund part of the price. Refunds go to the original payment method after inspection.
- Not refunded: original and expedited shipping, duties, taxes and customs charges, unless the law requires it or the store made the error. The return page does not say who pays return postage, and the older refund page excludes mistaken orders and change-of-mind returns from free after-sale service.
- Warranty: 24 months from purchase for manufacturing defects, with free repair, a replacement unit and free shipping both ways for covered repairs. Drops, liquid, DIY repairs, lightning, extreme temperatures and misuse are excluded (partial fees may apply), and damage from weak packing on the way back may not be covered. The older refund page still says 1 year.
- Seller: the site is run by Shenzhen Anba Technology Co., Ltd (Shenzhen, China) and HONGKONG LONGSHENG Import and Export Trading Co., Limited (Hong Kong); support is by email at [email protected]. These terms cover orders placed on doukaudio.com; other sellers apply their own.
For this product, the page lists US, UK, EU, AU and Other under 'Shipping to' and shows Free Shipping, 2-8 Days Arrival, 30-Day Return and 2-Year Warranty badges near the price.
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
Does the Q10 include a power supply?
It depends on the version you choose. The 19V/4.74A power supply is optional; the version without one accepts any DC 9-24V supply, and Douk Audio recommends a larger adapter for higher output.
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?
The Q10 ships with a 3.5mm AUX cable, an RCA cable and an optical cable, plus a user manual. The power supply is optional.
What is the return and warranty policy?
Douk Audio's current policy pages give you 30 days from delivery to request a return, which Douk must approve before you send the item back (within 7 days of approval); original shipping fees and duties aren't refunded. Its warranty covers manufacturing defects for 24 months from purchase, with free repair or replacement.

What we couldn’t verify
- 'Less than 0.001% distortion' and 'THD below 0.001%' come with no test power, load or frequency; the page pairs them with an S/N ratio of only above 89dB and does not say how the two relate.
- The dimensions print as 77*22*62mm, but the inch figures (3.03*2.44*0.87in) match 77*62*22mm; the page does not say which order is right, and the review uses the metric line.
- 'Each channel can max output up to 100W' has no load, supply voltage or current; the page lists a DC 9-24V input and an optional 19V supply but no output figure for either.
- The optional supply is given as 19V/4.74A in the store's product description and the review; the page text read on Oct 25, 2026 names only '19V Power Supply (optional)' with no current rating.
- Bluetooth 5.0 'low latency and up to 50ft' is a claim with no test conditions, and the page lists no codecs.
- $36.99 is the Without Power Supply option, the one the page opens on; With Power Supply is $47.99. The cheaper option leaves out the 19V supply, so you need your own DC 9-24V supply.
