iFi Audio ZEN Air DAC USB DAC Headphone Amplifier

Better Sound for Under $100

If your headphones plug straight into a computer, you're not hearing what they can do. The iFi ZEN Air DAC replaces your computer's built-in audio with a dedicated Burr-Brown DAC chip and a real headphone amplifier, in one compact desktop unit that costs less than most headphone upgrades.

It handles hi-res PCM up to 384kHz, native DSD256, and DXD, and it renders MQA for services like Tidal. The headphone output delivers 230mW into 32 ohms through a 6.3mm jack, with a low 1-ohm output impedance. Two iFi signatures carry over from the pricier ZEN DAC: XBass+, an analog bass boost that adds low-end weight without digital processing, and PowerMatch, a +6dB gain setting for harder-to-drive headphones.

RCA line outputs on the back also let the ZEN Air DAC feed powered speakers or an amplifier, so it can upgrade a desktop speaker setup, not just headphones.

What Reviewers Are Saying

Louis Gonzalez of Headfonics scored the ZEN Air DAC 8.1 out of 10 in a July 30, 2022 review, describing its sound as "rather neutral with a hint of Burr Brown warmth," where "vocals come through rather sweet, the bass is well extended, and the high frequencies extend well." His verdict: "What iFi Audio did here is fill an empty void by introducing a very good-sounding desktop DAC amplifier combo for less than 100 bucks."

Who Is This DAC Best For?

• You listen to headphones at a computer — this is the classic first upgrade, and one of the most affordable ways to hear a real difference.
• You stream hi-res music — support for PCM 384kHz, DSD256, and MQA rendering covers every major service.
• You want to feed powered speakers too — the RCA outputs turn it into a compact desktop source.
• If your headphones use balanced cables or need serious power, step up to the ZEN DAC or a dedicated amp — the Air's single-ended 230mW output has limits.

How Does It Connect to Your System?

One USB-B cable (included) carries both audio and power from your computer, so setup takes about a minute. If you prefer, a 5V power supply (sold separately) can power it instead. Plug headphones into the front 6.3mm jack, or run the rear RCA outputs to powered speakers or an amp.

Frequently Asked Questions

Does it need its own power supply?

No. It runs on USB power from your computer, though a 5V supply (sold separately) can be used instead.

Will it work with hard-to-drive headphones?

The PowerMatch gain switch adds +6dB for demanding headphones, but very hard loads are better served by a more powerful amp.

Does it support MQA?

Yes, it renders MQA for full-quality playback from services like Tidal.

What's the warranty?

iFi covers the ZEN Air DAC with a 1-year manufacturer's warranty.
