The Marhynchus ME1 is a small, focused tool for anyone working with electret microphones. It solves a specific problem: adding clean, adjustable gain between 0 and 20dB without introducing noise. The MC33202 operational amplifier inside handles the amplification, and the built-in bias voltage means you can plug in compatible mics without needing phantom power.

The 3.5mm input makes it dead simple to integrate into an existing setup. You can use it with a portable recorder, a podcast mixer, or even a smartphone with a USB adapter. The 150mAh battery delivers over 10 hours of continuous use, which covers a full day of field recording or a long podcast session. Recharging via a standard phone charger is straightforward. At 3.84 ounces, it disappears into a bag or pocket.

The gain adjustment is a physical knob, not a digital menu. That means you can dial in the exact level while monitoring in real time, which is far more practical than hunting through software settings. There is no on/off switch, so you will need to unplug the battery to save power when not in use. For the price, this is a reliable, no-fuss solution for getting a stronger signal from your electret mics.
