Nobsound NS-10G Bluetooth Amplifier 50W+50W Review

The Nobsound NS-10G is a mini Bluetooth digital amplifier priced at $29.99. It is rated at a maximum output of 100W total — 50W x 2 — using the upgraded Texas Instruments TPA3116 chip, and the maker states it delivers HiFi clear sound with no audible noise even at high power output.

Inputs cover the practical bases: Bluetooth 5.0 + EDR for faster and more stable wireless transmission from phones and tablets, a USB input that needs no driver and works plug-and-play, and AUX for traditional devices such as iPod, CD players and computers. The maker positions it as compatible with most home audio devices.

A dedicated bass button is specially designed to amplify low-end effects for a cinema-like listening experience, while the volume control is smooth and precise. The amplifier is built into an attractive aluminum case measuring only 80x53x22mm and weighing 105 grams, making it suitable for home and desktop audio systems where space is tight.

Power comes from an external DC 9-24V supply rated 3A or above; the amplifier itself has no internal power source, and the listing offers versions with and without a power adapter, so the without-supply variant needs a suitable adapter of your own. The package includes a 3.5mm audio cable, an RCA cable, a USB cable and a manual. Note there is no headphone output — this one is for driving speakers.

Specifications

How it compares

The NS-10G's review price of $29.99 is the Without Power Supply option; with a power supply it costs $39.99. Its closest twin, the Nobsound NS-01G PRO, lists $31.99 without a supply and $39.99 with one: the same TPA3116 chip and 50W x 2 rating, Bluetooth 5.0, USB and AUX inputs, in a larger case (78 x 70 x 38mm and 154g, against 80 x 53 x 22mm and 105g) in five colors. The Nobsound NS-10G PRO ($32.00 without a supply, $39.99 with one) moves to a TPA3221 chip rated 100W x 2 with Bluetooth 5.0 + EDR + DSP and a 15m range, but lists no USB input and, by design, no volume control. The Nobsound TONE ($39.99 with a 19V adapter in the box) lists the same 50W x 2 at 4Ω with Bluetooth and AUX only.

Who it suits: the NS-10G fits a very small desk or shelf system that wants a USB input and a bass button, at $29.99 if you already own a DC 9-24V supply of 3A or more. The NS-10G PRO lists twice the rated power for buyers who can live without USB and a volume knob, and the TONE suits a buyer who wants the adapter included at the same $39.99 as the NS-10G with a supply.
