iFi nano iDSD BL

Headphone Amp/DAC


The nano iDSD Black Label, with its Hi-Res DNA and crystal-clear sound, brings your headphone listening experience to a whole new level.

Perfectly balanced.
The nano iDSD Black Label is a powerful piece of kit.

It’s six times more powerful than an iPhone, drives almost any set of headphones and with up to ten hours of battery life, makes listening on the go stress-free.

And with its advanced engineering and balanced wiring, it’s ideal for single or balanced earphones alike.

The tech spec
The nano iDSD Black Label has two other iFi products built in:

  • The iPurifier – To isolate sound and deliver clean, quality music,
  • The iEMatch – To attenuate high-powered earphones and sensitive in-ear monitors

They take away hiss, buzz and distortion and provide studio-quality audio.



True Native® playback of all music formats from MP3 to DSD256, PCM384 and DXD384.




Listen to MQA straight out of the box.

For MQA tracks, simply connect to Tidal (on your computer) and check the options to stream MQA.




Hear music as the artist intended. The Burr-Brown True Native® chipset means file formats remain unchanged for the truest sound.




The iFi exclusive S-Balanced technology delivers the maximum performance from single-ended and balanced headphones alike.

Reap the benefits of balanced, enjoy lower distortion and reduced crosstalk.




Visible analogue volume control. Its smooth action and smooth sound deliver the sonic goods with precision.




Choose between the ‘Listen’ (Minimum Phase Bezier Filter) and ‘Measure’ (Linear Phase Transient Aligned Filter) options.

It’s the only portable DAC to give you so much control.




With up to ten hours of battery life, you can max out your on-the-go listening. Just switch it on and then plug in your device. Plus it boasts a USB Type A connector for a stable wired connection.

Just use an Apple CCK cable or Android OTG cable and away you go.


iFi OTG cables for Android: USB-C and USB-Micro - $20 CAD






Perfect for use with Android phones. They extract a digital signal with ease.

We offer the USB-C version at USB3.0 standard and the micro-USB.




The USB 3.0 'A' Female connector provides a much more mechanically reliable connection, a factor that not many manufacturers take into account.

This fits directly into a flat Type A USB port and ensures a strong and steady audio connection.




Our audiophile grade OTG cables are constructed from pure OFHC continuous cast copper, which conducts clean sound between your Android and DAC.



And it’s not just the insides that get the iFi treatment.

The cables are not only sonically superior but also super smart looking with a sexy ceramic finish to add that touch of class.

Note: iOS users wanting to connect an iPhone must use an Apple Lightning to USB Camera Adapter (pictured below)

Paul Rigby- The Audiophile Man

"A compact unit, ideal for mobile use, the nano iDSD proved to offer superb sound for its diminutive size. Covering a range of resolutions and connectivity options, the iFi Nano iDSD BL provides excellent value for money too."

Hifi Pig

"Rarely, if ever, have I classified a piece of gear, in this case a transportable rechargeable battery powered headphone amp/DAC as a no brainer.” “It is not just a portable/transportable solution. I could very well see some folks using this product as their desktop/system DAC. There are several sub £500 DACs out there which should be quaking in their boots right about now."


"iFi’s Nano iDSD Black Label is a brilliant headphone amp/DAC that offers serious sound quality in a very compact and affordable package – similarly priced rivals have far less functionality making it excellent value, too."

Plenty of power, flexibility and the full gamut of high-res formats with superb sound quality at an affordable price. What more can you ask for?
