Enjoy unbeatable HD Bluetooth streaming from your phone, tablet or computer.

ZEN Air Blue

Get maximum sound quality from Bluetooth audio with the ZEN Air Blue.

The ZEN Air Blue is a high-quality Bluetooth audio receiver.

It converts Bluetooth audio streams from smartphones, computers or tablets into an audio stream suitable for headphones, amplifiers and active speakers (speakers that run on their own DC power).

Hear the difference

The ZEN Air Blue will give you the maximum sound quality from your device – your smartphone, computer or tablet – as it operates at the highest audio resolution level of any Bluetooth system.

The Bluetooth system inside has been upgraded by iFi to avoid the 40% drop in audio quality you typically experience with standard Bluetooth (compared to wired audio).

It’s the ideal way to wirelessly connect your smart device to a sound system in super hi-res (high resolution).

Effortless. Easy.

The ZEN Air Blue is ideal as part of a simple, new set-up for someone just starting out in audio who wants to experience the high quality of music streaming apps like Apple Music, Tidal and Qobuz.

Just connect your laptop, smartphone or tablet to the ZEN Air Blue via Bluetooth and connect the ZEN Air Blue to your amplifier or active speakers via the RCA connections at the back.

Compatibility. Covered.

The ZEN Air Blue supports any current Bluetooth stereo audio codec (signal) available on the market today.

  • AAC – better than SBC, widely used, found in Apple devices
  • aptX HD, aptxLL and aptX Adaptive – variations on an improved aptX
  • aptX – better than SBC, widely used, found in Android devices
  • LDACTM – extremely high quality, designed by Sony
  • LHDC – extremely high quality, designed by Huawei
  • SBC – standard Bluetooth used by most audio devices

Whatever device you are are using for streaming music via Bluetooth, we’ve got you covered.

HD quality streaming

It’s also an easy, reliable way to add Bluetooth streaming to an existing set-up or upgrade the sound quality of any speaker or system that uses standard Bluetooth.

  • Bluetooth v5.1 compliant
  • Excellent wireless range
  • Superb stability
  • Smooth performance

Let the Air into your system and blow the cobwebs away.


Thanks to the XMOS 16 core tech, the ZEN One Signature is an MQA Decoder.

This enables you to play back MQA audio files and streams, delivering the sound of the original master recording. The LED glows green or blue to indicate that the unit is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

MQA rendering technology (used in the original versions of some other iFi products) connects to an MQA Core signal and completes the final unfold of an MQA file. Core decoding is included in streaming services such as TIDAL, as well as select media players.

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.

Discrete ESS Sabre Hyperstream DAC chipset with time domain jitter eliminator, discrete oscillator and 112dB dynamic range for discerning listeners.

The iFi Bluetooth® implementation does not use a standard SOC (System On a Chip) as seen elsewhere. It uses a combination of quality elements to extract the most from each stage.

The Qualcomm chip routes the raw, digital Bluetooth® signal to a specialised Sabre DAC chip to convert the signal from digital to analogue – any jitter is eliminated using our GMT femto-precision clock system to deliver Bluetooth® that is a cut above.

TDK C0G (Class 1 ceramic) capacitors offer high stability and low losses for resonant circuit applications.

Getting ever closer to the theoretical ideal of pure, frequency-constant capacitance, these capacitors reduce capacitor-induced distortion to vanishingly low levels.

They are pricey but are a perfect addition to our products.

A key advantage of the ESS Sabre DAC chip is its Hyperstream architecture with integrated Time Domain Jitter Eliminator, which delivers vanishingly low distortion and a high dynamic range.

Texas Instruments low-noise ICs offer great unity-gain bandwidth, very low noise and distortion, high output drive capability, Common-mode and Power Supply Rejection Ratios of over 100 dB, wide maximum-output-swing bandwidths and high slew rates.

Thank you to Dennis at Wirecutter on their guide to bluetooth receivers! Here’s a snippet..

“The Zen Air Blue’s sound quality is on a par with that of Bluetooth audio receivers costing nearly twice as much, and its small number of connections and controls makes it easy and intuitive to operate”
