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.

Buying advice: headphone amplifier for iPhone

Match outputs to your headphones

Outputs decide which headphones you can plug in. The iFi amp has a 3.5mm unbalanced output and a 4.4mm balanced output, and the Fosi dongle has a 3.5mm single-ended output and a 4.4mm balanced output. The BZINK adapter has a 3.5mm output. Check your headphone plug before you buy, since a balanced plug needs a balanced output.

Decide between battery amp and dongle

A battery amp runs on its own power, and a dongle draws power from the phone or computer. The iFi amp runs 6 to 8 hours on battery, while the BZINK and Fosi dongles draw power from the connected device. Pick the battery amp for listening away from a charger, and a dongle for a direct connection to your phone.

Check decoding specs before buying

Decoding specs show which audio formats the amp can handle. The BZINK adapter supports up to 32-bit/384kHz audio, and the Fosi dongle decodes up to DSD256 and PCM 32-bit/384kHz. The iFi amp has an MQA decoder for MQA files. If you play high-resolution files, match the decoding spec to the files you own.

Frequently asked questions

Do I need a DAC for my iPhone?

Yes, if you want wired headphones on a USB-C iPhone. A DAC turns digital audio into analog audio for the headphone jack, and all three picks here have a built-in DAC.

What is the difference between 3.5mm and 4.4mm?

The 3.5mm plug is a single-ended connection, and the 4.4mm plug is a balanced connection. The iFi amp and Fosi dongle have both outputs, while the BZINK adapter has a 3.5mm output.

Can a dongle drive over-ear headphones?

It depends on the dongle and the headphones. The Fosi dongle drives up to 170 mW per channel at 32 ohms, and the iFi amp drives up to 400 mW. Check the power figure against your headphones before you buy.
