Our take on the Class-A 16-300 Ohm HiFi Headphone Earphone Amplifier 3.5mm Jack Aux Portable Adjustable Audio Amp for Phone Music Player

This is a small aluminum-bodied headphone amplifier that takes a 3.5mm input and drives headphones rated 16 to 300 ohms. It is a simple inline amp: plug a phone or music player into one end and headphones into the other, with a USB cable for power. It suits listeners whose phones or players sound thin or quiet with higher-impedance headphones. Against dedicated portable amps from Fiio or Topping it is a bare-bones unbranded unit with no DAC, no display and no stated power figures, so it competes on simplicity rather than measured performance.

Questions and answers

Will it drive 300 ohm headphones?
The maker rates it for 16 to 300 ohms, so it is intended for high-impedance headphones. There are no published power figures, so how loud it gets with hard-to-drive models is unknown.
Does it work with a phone?
Yes. It takes a 3.5mm output from a phone or music player and feeds headphones from its own jack. Phones without a headphone jack need an adapter.
Does it have a built-in DAC?
No. It amplifies the analog signal from your source, so the sound quality of your phone or player still matters.
What is in the box?
The amplifier, one 3.5mm audio cable and one USB cable. Headphones and the audio source are not included.
How is it powered?
Through the included USB cable. It has no internal battery, so it needs a USB port or charger to run.
Can I adjust the volume?
It has an adjustable gain control. You still set the main volume on your phone or player.
