Hi-Res True Native® playback for all music formats from MP3 to DSD512, PCM768 and 2xDXD.
Our portable DAC and headphone amplifier will improve the sound quality of your music.
Whether you are listening via headphones on the bus or via your system on the sofa, the award-winning xDSD makes your music sound better.
Wireless. Wired.
The xDSD is for people who love to listen — on the go or at home.
You choose wireless via Bluetooth® or wired via USB or SPDIF.
Apple or Android, DAP, games console or TV, just connect the xDSD and enjoy the ultimate audio experience.
Hi-Res. Future-proof.
The xDSD plays high-quality digital audio file formats up to DSD512. Listen to your favourite tracks as they were meant to be.
In love with Hi-Res streaming? Listen to Tidal HiFi and Spotify Premium with ease.
The xDSD is also MQA ready straight out of the box. Use with Tidal Masters on your computer or mobile.
Bluetooth freedom
The convenience of Bluetooth® means your headphones connect to the xDSD, leaving your phone or chosen device wire free. Pop the xDSD in your pocket and it’s business as usual but with much better sound.
The xDSD boasts both aptX™ and AAC™ Bluetooth® for CD-like quality. With standard Bluetooth®, the sound quality drops by 30%, not so with the iFi Bluetooth® implementation. Just a little iFi magic for you!
Superior sonics
With amazing amplification, driven by 500 mW of power, the xDSD handles almost any headphones and it easily partners up with active home speakers.
And, of course, we’ve included our exclusive optional ‘sonic fine-tuning extras’ to add further nuances to your listening.
xBass+® cleans and restores the bass to give you a richer, deeper sound and 3D+® opens up your music to bring a live-concert atmosphere into your living room.
Perfectly balanced
iFi’s exclusive S-Balanced technology means that you gain the advantages of a balanced connection even when using an unbalanced one.
On headphones this means lower distortion, less interference, and reduce crosstalk.
Smart. Stylish.
The battery lasts up to 10 hours and ‘smart’ tech ensures you enjoy optimum listening time adjusted according to your usage. The xDSD has a separate USB charging socket.
And finally, with its metallic chrome finish and elegant, ergonomic design, based upon the Japanese Zen garden, it puts the ‘x’ back into sexy.
Connect your phone or device wirelessly via aptX™ and AAC™ Bluetooth®. Whatever your device, we’ve got it covered. Read more on iFi’s take on Bluetooth® here.
We use the USB Type-A connector as it provides a more stable audio connection for better playback and because of the OTG cable for Android and CCK Lightning to USB cable for Apple. The 3.5mm coaxial/TOSLINK combo SPDIF input allows connection to older DAPs and CD players.
Battery life is up to 10 hours. Charging is via the separate USB charging cable included.
The Burr-Brown True Native® chipset means file formats remain unchanged. Listen to music as the artist intended in the format in which it was recorded.
Listen to Master Quality Authenticated audio straight out of the box. Connect to Tidal Masters and check the option to stream MQA.
Our video tutorials on You Tube show you how.
iFi’s exclusive S-Balanced® circuit delivers maximum performance from single-ended and balanced headphones alike.

Reviews
Superb and versatile portable DAC and headphone amplifier
Using my iFi XDSD with Audeze planar magnetic headphones. Great sound, comparable with Chord (which remains the gold standard) but with more versatility, ease of use and input options including BlueTooth. Superb with Tidal on Mac, PC or iPhone as well as hi-res audio format files. Really impressed with the sound quality, ergonomics and portability

Wow…wow…wow!! Would be a bargain for 2x the price
I absolutely love this device. I’m listening to Tidal Masters and DSD’s on my JH Lola IEM’s and the sound is unbelievable. I’m using a 2.5mm balanced male -> 3.5 balanced female adapter, which made a pretty dramatic difference versus an unbalanced.
I had hesitated a little because the thing looks much bigger in pictures. It’s actually quite tiny in my hand – the hand model must be a munchkin. Beautiful construction and intuitive controls. Love when the purple light tells me I’m listening to an MQA
Plenty of power on the IEM’s. Will test with my Audeze LCD-2’s as soon as my 4.4mm balanced female -> 3.5 balanced male adapter arrives
Haven’t tested the Bluetooth yet…

MIGHTY MOUSE
I really did not know what to expect out of this little POWERHOUSE.It really does the job for being a small amplifier. I’m using my Sennheiser HD 650’s . Crystal clear . Makes you feel like your floating on a cloud. The Bluetooth is a bonus. I take it every where.
I’ve always been into higher quality sound systems. This is one of my favorites because I’m able to take this quality amp with me anywhere. Make sure you do your homework and check things out for yourself as well.

HIFI for your pocket
The device is small and light, fits in every jacket pocket. The battery lasts for at least 6 hours. The sound is rather cool and analytical, very defined and genuine. The 3D + and Bass + functions change the sound only minimally, but are still useful.
The available input connections are diverse, so that you can actually interpose this DAC anywhere. The housing and the rotary wheel are very valuable, in contrast to the supplied fabric bag.

DAC (Digital-to-Analogue Converter)
DACs convert digital information, stored or streamed by computers, into music we can hear through speakers or headphones.
Every device that’s a source of digital sound has a built-in DAC (TVs, games consoles, CD players, phones, portable music players etc). Dedicated external DACs sound much better than standard DACs used in digital devices such as phones.
DAP (Digital Audio Player)
A DAP is a device like an iPod or an MP3 player that stores and/or plays back music digitally.
DSD (Direct Stream Digital)
DSD is a very high-quality digital audio format that’s even better than CD quality. The higher the ‘DSD rate’ – DSD64, 128, 256, 512 and 1024 – the greater the amount of music information available, which means better sound quality.
Files can be remastered to higher file rates to improve sound quality. The pinnacle of this is DSD1024. Not many machines out there are capable of this feat.
Spotify Premium
Spotify Premium allows you to listen better quality music. It’s all about bitrates. The bitrate is the amount of data processed over a certain amount of time. The higher the bitrate, the better the quality.
On normal Spotify you listen at 96kbps, the ‘standard’ bitrate on mobile or at 160kbps, ‘standard quality’ on desktop and ‘high quality’ on mobile.
With Spotify Premium, you get 320kbps which is ‘high quality’ on desktop and ‘extreme quality’ on mobile. Basically, more bitrates for your buck.
MQA (Master Quality Authenticated)
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. More here.
Tidal Masters
Tidal is a subscription-based audio streaming platform, similar to Apple Music and Spotify, but with lossless-quality audio. Tidal Masters is the section with the highest-fidelity music streamed including some files in partnership with MQA.
Lossless-quality means that no music quality is lost in this format.
AAC
AAC is one of the most commonly-supported Bluetooth codecs in the wireless headphone and speaker markets. It’s also the default audio compression codec used by Apple’s iTunes and YouTube and is supported across both iPhone and Android smartphones.
Balanced 'v' Unbalanced
Let’s talk headphone cables.
An unbalanced headphone cable has a left + and right + wire, for each respective side. The other, the third – wire is shared by both left & right channels. As this is shared, this gives rise to undesired coupling noise which is commonly referred to as ‘crosstalk.’
A balanced cable has the same left + and right +. But it has a separate left – and right -. With totally separate wiring ‘crosstalk’ is negligible.
Therefore, a balanced connection is the superior headphone wiring configuration.
