Weighs only26g
Thats less than an AA battery!
Max sonics. Free the Smartphone.
Traditional wireless headphones or earphones of any kind integrate Bluetooth processing, D/A conversion and amplification onto one, standard off the shelf chip. There is a ceiling to the sound quality that can be achieved.
Team good corded headphones or in-ear monitors, with a separate, high-quality portable DAC/headphone amp, and your sound quality will beat any pair of wireless headphone or earphones hands down.
TheGO blumeans no compromise on sound quality.
Pair theGO bluto your Apple/Android. Connect your favourite corded headphones to theGO bluand then tuck it away its so petite it will slip into your running gear or suit pocket. Its also gorgeous enough to show off by leaving it on the table at your favourite coffee shop!
Super Sound. Assured.
Most pocket-size Bluetooth DAC/headphone amps incorporate all-in-one system on a chip solutions to deliver input processing, digital-to-analogue signal conversion and amplification.
Not theGO blu.
Uniquely, for a device of this type and size, theGO blus clever design packs in separate Bluetooth, DAC and amp stages, each engineered in distinct blocks to deliver the ideal combination of cutting-edge specification and superb sound.
HDBluetooth.
TheGO bluuses the same Bluetooth 5.1 as seen in other recent iFi products. Furthermore, we have separated the modules so that every last drop of audio quality is unmatched.
- AACaptXaptX HD, aptX Adaptive, aptX Low-Latency
- LDAC& HWA/li>
- Bluetooth 5.1TM at 24/96kHz.
And when you wish, just use the USB-C connection and enjoy High-Res USB audio too!

The balance of power.
Diminutive. Balanced. Powerful.
TheGo bluamp circuitry benefits from symmetrical twin-mono signal paths and utilises iFisDirect Drivedesign concept. Plus it incorporates circuit components of a quality not commonly found in a device of this kind.
This means ultra-low distortion across the entire signal bandwidth. The sound is purer, clearer and more naturally expressive.
The amp stage delivers up to 5.6V, considerably more power than others. It handles tough headphone loads with ease. Auto-gainadjusts output up or down by 6dB to ensure signal strength suits the sensitivity of the connected headphones/earphones.
Swiss Chrono design and implementation.
GO blusChronoDialis a masterpiece of precision engineering and, just like a Chronograph, it gives you precise, analogue volume control. You can use it to play, pause, and skip tracks forward and backwards and even activate the voice assistant on your Bluetooth-connected smart device. Heres how its constructed:
- Brass supporting column with anti-corrosion
- Brass locking nut with anti-corrosion
- Precision 304 stainless steel bearing
- 304 stainless steel main dial with beryllium cobalt copper coating
- High-purity nickel push-button spring
- Precision CNC machined AL6063 aluminium push button
GO Balanced.
Whether you use balanced or non-balanced headphones, you get the least noise and best channel separation for the most enjoyable music.
TheGO bluboasts a Pentaconn 4.4mm output enabling headphones equipped with balanced connectivity to take full advantage of theGO blus balanced amp design.
In addition, the 3.5mm output benefits from iFis proprietaryS-Balancedcircuitry. This cuts crosstalk and related distortion in half when used with regular, single-ended headphone connections, this is especially beneficial with high-sensitivity in-ear monitors.
Both outputs are gold-plated to resist tarnishing and thereby maintain optimum contact quality.
X-factor. Inside and out.
WithXBassto add back lost low-end grunt andXSpace to widen the soundstage, theGO bluis small on the outside but mighty on the inside. You will be immersed in its majestic musicality.
The X-factor doesnt stop with the sound. TheGO bluis built like a luxury Swiss watch the volume control has a watch crown machined by a watchmaker for the tightest of tolerances and has the luxury feel of Mont Blanc, thanks to our French product designer.
Made with the latest, most hi-tech materials and weighing in at a super featherlight 26grams or 0.06lbs, it will be your go-to music device.
We use Qualcomms new QCC5100 Bluetooth IC in combination with the Cirruc Logic 43131 as DAC to to create an audibly superior Bluetooth engine.
All the current high-definition Bluetooth audio formats are supported Qualcomms aptX Adaptive and aptX HD, Sonys LDAC and HWAs LHDC, regular aptX and aptX Low Latency, AAC (Apple iOS devices) and SBC (the plain vanilla Bluetooth codec).
Of the 24-bit-capable codecs, aptX Adaptive and aptX HD support up to 48kHz, while LDAC and LHDC reach 96kHz.
iFis Bluetooth engine can also be updated over-the-air, so future codecs may be added.
It is a superior method to the traditional single-ended circuit approach. Balanced circuits reduce noise and crosstalk. Less Interference clearer sound.
You normally find this set-up in products at the higher end of the price spectrum such as the Pro iCAN but iFi is now using this across its range to produce the best quality audio for all our customers.
As with many other iFi audio products, weve incorporated a custom OV Series operational-amplifier. This top-notch component contributes to the extremely low noise, low distortion (0.0001%) and wide bandwidth.
An important aspect of the circuit design is its direct-coupled nature (no coupling capacitor is present), achieved without a conventionally applied DC servo.
DirectDrive equals a direct signal path which means less signal degradation. This direct signal path is unequalled in audio and is the reason why the sound is so true.
XSpace is the iFi analogue signal improvement circuitry to get that music back outside of your head for much better headphone enjoyment.
XBass is an analogue headphone spatialiser. It opens up your music to give you the feeling of spaciousness experienced at a live concert.
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.
muRata control-type, low-ESR high-Q multi-layer capacitors. The ESR control aspect of the Murata is something special. Their noise suppression abilities are impressive.
