Naim Audio Uniti Atom Headphone Edition

All-in-One Streaming Player with Superb Headphone Amp and Preamp Functionality

Naim's Uniti Atom Headphone Edition is a headphone-optimized version of the award-winning Uniti Atom music streaming system, designed to be the ultimate solo listening source. Unlike traditional headphone amplifiers and DACs, which require a separate computer or streaming device, Uniti Atom Headphone Edition is a fully formed streaming system: just add headphones. It is also a superb streaming pre-amplifier. Simply add a power amp and speakers – or active speakers.

Enjoy your music, at your volume, exactly how it’s supposed to be heard. No disturbance, no distractions, no compromise. City office, home study, living room, or bedroom. Transform any space into your own audio cocoon, lovingly crafted by the British leaders in high-end sound. Music, radio and podcasts have never sounded so good.

Uniti Atom Headphone Edition is fully re-engineered to offer the optimal personal listening performance. Using trickle-down technology from its flagship Statement amplifier, Naim has engineered a new discrete headphone amplifier, capable of powering even the most premium headphones with ease, via your choice of 6.35mm jack, Balanced XLR or Pentaconn outputs.

Unique Music Streaming Platform

Naim’s unique music-streaming platform serves up incredible sound quality, allowing you to escape into your own digital music collection, services such as Qobuz, TIDAL and Spotify, and a world of Internet radio – including a curated collection of HD stations - and podcasts.

AirPlay 2 support, Chromecast built-in and Roon Ready status add even more streaming options, while analog and digital inputs mean you can connect many other sources, too – including turntables – and a USB input supports playback from sticks/drives. Enjoy a huge range of music file formats, in resolutions up to 32bit/384kHz.

Explore and curate your audio choices via the Naim App, with further control options offered by a wonderfully tactile volume dial and full-color display (that can be switched off it you like to listen in the dark). The Naim App also seamlessly integrates with other Naim streaming products in your home.

Streaming Features and Services

The Atom Headphone Edition allows you to use UPnP™ (Universal Plug and Play) to read music from storage, or PCs and Macs on the same network as your Uniti, control it all with the Naim app and enjoy playback at up to 32bit/384kHz resolution.

Atom includes native support for Chromecast built-in. This smart new streaming service creates a seamless link to hundreds of supported apps from your smartphone or tablet and streams directly to your Uniti system.

Discover millions of songs from the world’s most popular streaming service with the built-in Spotify Connect feature. The lossless high definition TIDAL streaming service is integrated into Uniti for an immersive, high-quality sound experience. Tune in to thousands of available internet radio stations and podcasts or curate your favorites for quick access later via iRadio.

Pair your Uniti Atom Headphone Edition with any compatible Bluetooth device for simple high quality playback of music from that device. With Apple AirPlay2 and Apple Music, stream music from your iPhone, iPad, or iPod Touch or from iTunes and Apple Music.

"The Naim Uniti Atom Headphone Edition proves that when you focus on the key thing that makes your product unique — and wrap already proven hardware and software around it — you’re probably going to create something of value."

"...this is one piece of audio hardware that won’t be obsolete anytime soon and has this very experienced headphone reviewer completely smitten."

- Will Jennings, ecoustics.com, December 20, 2022

"There are any number of quality headphone amps on the market, as well as great streamers. But Naim's Uniti Atom Headphone Edition stands out for combining the two in a package that delivers style, ergonomics, and superb sound at a very reasonable price. That should prove appealing for both young music lovers and grizzled audiophiles who want to set up a self-contained, compact system for headphone listening in a private space."

"But where the HE truly shines is when it's asked to do more than that. Its excellent internal linestage and volume control allow it to drive the very best powered speakers when called upon to do so. Later, if asked to drive a reference-class power amp while supporting top-shelf digital and analog soures, the HE is capable of doing so at a level within glancing distance of far more expensive gear."

In sum, the Naim Uniti Atom Headphone Edition will get you started down the audiophile road and will take you as far down as you'd like it to go.

"Naim Audio's Uniti Atom HE was that rare audio product that charmed and impressed me completely. It seemed to excel at everything. It was always a joy to use, and I felt sad as I carted it to FedEx."

- Herb Reichert, Stereophile, August 24, 2021

"The Naim Uniti Atom Headphone Edition is an excellent-sounding all-in-one digital music streamer."

"...it stands alone in the market thanks to its gorgeous design and musicality. While you could assemble a system that sounds as good, it’s difficult to match what the Atom offers as a complete package."

- Lewis Leong, TechRadar, July 2021

"...I’ve come across the first device that I’ve ever encountered that puts up a compelling claim to be the sole device that you’ll ever need to park on your desk to enjoy stunning headphone listening – and all with an utterly seamless user experience to boot: the brand-new Naim Uniti Atom Headphone Edition."

"The Naim Uniti Atom Headphone Edition is the first device that’s come along that has genuinely made me believe that the ‘future is here’ when it comes to how we can enjoy listening to headphones. I cannot overstate how impressive the total product experience of this device is, from the first opening of the box to the time that you have to switch it off and say “good night” to it at the end of the day. Naim has absolutely knocked it out of the park in terms of building a one-box solution that provides you with the ability to simply grab a pair of headphones, and start playing music into them from any number of sources – and that’s selling it short."

- Matty Graham, Headfonia, May 18, 2021

"There's no way to soften it, Naim Uniti Atom HE is a premium product at a premium price. Retailing at $3,290—it’s not cheap! But for the price you’re getting luxury-tier quality in hardware, design and sound quality built to keep pace with the best headphones made today."

"Naim has proved once again that it has one foot in today's Internet streaming technology with the other firmly planted in innovative amplifier topology, and it's a great combination in audio today. But what I personally love best about Uniti Atom HE are the little details in usability that pushes the Internet streaming technology out of the way and simply encourages my love of musical exploration and discovery every time I turn it on."

- Wayde Robson, Audioholics Online A/V Magazine, May 11, 2021

"As its name suggests, Naim Audio is marketing the Uniti Atom Headphone Edition as a serious headphone amp that’s also a DAC/preamp and streamer – but it’s actually able to fulfil all these roles very capably and in no particular order."

"...this little box combines excellent real-world functionality with super sound at the price. This applies across all sources and whether it’s being used as a preamplifier or a headphone amp – which is no small feat."

"A highly talented all-rounder with a style and charm of its own, it’s an essential audition if you’re after a compact, quality sound solution."

- David Price, StereoNET™ UK, May 11, 2021

"The Atom HE is an excellent addition to the Naim Uniti range – something genuinely different in offering a streaming preamplifier with a top-quality headphone amplifier. Use it alone with headphones, with power amps, or with active speakers, and you have a system just as versatile in its streaming abilities as the Mu-so, more versatile in its connections, and far higher in its hi-fi quality. And it comes with the best knob in hi-fi. It’s a big thumbs up from us."

"The new Atom’s headline ability is headphone playback, but don’t underestimate its value as a preamplifier. It’s a classy and versatile addition to Naim’s Uniti range."
