How we ranked these headphone amps
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Built-in DAC weight 2
- Balanced output weight 1
- USB connection weight 1
- Runs on batteries weight 1
Buying advice: headphone amp under 50
Count the headphone outputs first
Output count decides which amp fits your setup. The FIFINE splits one source to 4 outputs, each with its own volume knob. The LVY and the MYPIN each use one 3.5mm output, and the TNP offers a 3.5mm or 6.35mm output. If four people monitor one mix at once, the FIFINE covers that setup, while a single listener can use any of the other three picks.
Match inputs to your source device
Input type decides whether the amp connects to your source. The FIFINE uses a 1/4 inch TRS source input, the LVY and the MYPIN use 3.5mm AUX input, and the TNP supports stereo 3.5mm or RCA input. Check the output jack on your source device before buying, and remember the TNP connects only one input at a time.
Check battery life or power source
Power source decides where you can use the amp. The FIFINE runs on an included 12V DC power adapter, the TNP runs on Micro-USB power input or a DC adapter, and the LVY runs for more than 5 hours while the MYPIN runs for more than 12-15 hours. A rechargeable amp suits listening away from an outlet, while an adapter-powered amp suits a fixed desk setup. Compare the power figures with how you plan to use the amp.
Frequently asked questions
Can one amp drive four headphones at once?
Yes, the FIFINE splits one stereo source to 4 outputs, each with its own volume knob. All four headphones can connect at once with no loss of signal.
What is a two-stage gain switch?
A two-stage gain switch enhances the signal input into the amp circuit for the optimal performance of the headphones. The LVY and the MYPIN both include this switch, with 3.5mm input and output on each.
Do I need an amp for high impedance headphones?
An amp helps when headphones need more drive than a source device gives. The LVY and the MYPIN both support headphones of 16-300 ohm impedance, so check the impedance range before buying.
Can I use a headphone amp with a phone?
Yes, with a 3.5mm connection. The LVY works with phones and the MYPIN works with phones, MP3 players and computers, so pick the amp whose input matches your phone output.
