Douk Audio M08E Mini FM Radio Tuner Preamp Headphone Amplifier Review

The Douk Audio M08E is a mini FM radio tuner, preamp and headphone amplifier priced at $39.99. The spec sheet lists it under Nobsound's model numbering, and it is built as a compact all-in-one for small desktop, bedroom or workshop systems that want radio plus a bit of tone control and a headphone option.

The FM section uses an SI4831 radio chip with three selectable frequency ranges - 64-87MHz, 76-90MHz and 87-108MHz - switched with one touch, which covers the broadcast bands used in different regions. Reception quality depends on placement: Douk Audio recommends keeping it away from sources of electromagnetic interference and near a window, and adjusting the antenna patiently for the strongest signal.

On the audio side, a 3.5mm AUX input takes CD players, phones or laptops, and the M08E can act as a preamp feeding a power amp or active speakers, or you can listen privately through the TPA6132 headphone stage, which is matched to 16-32 ohm headphones. Treble and bass knobs and dual NE5532 op-amps shape the sound, the aluminum body keeps it durable, and mute/unmute plus status indicators keep operation simple. It defaults to FM mode and switches automatically to AUX input when a cable is plugged in.

Douk Audio ships worldwide with free and expedited options; costs vary by country.
