    Super light, super sound HD Bluetooth DAC - Apple Music, Spotify, every song on the GO! iFi Audio's new GO blu, pocket-rocket portable HD DAC/amp, is diminutive enough to take with you wherever you go! It gives you best sound from wired but the convenience of wireless as you no longer need to have a cable connection to your smartphone.

    Every possible source device is handled at the highest audio resolution its Bluetooth specification allows – no other pocket-size DAC/amp delivers such comprehensive codec support, or such high-quality sound over Bluetooth. The GO blu is Bluetooth v5.1-compliant, ensuring the best possible range, stability and performance, and its ‘Bluetooth engine’ can be updated over the air.

    Whether you’re exercising at the gym with your Apple watch clocking your every step or catching up on your MacBook at your favourite coffee shop, the GO blu is the perfect companion. It pairs wirelessly with your source device via Bluetooth with no need to worry about whether you’ve got the right cable for your Android or Apple device. Just pair, and GO!

    Every day is a GO blu day!

    Superior sound. Unbound.

    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.

    No compromise on sound quality

    Pair the GO blu to your Apple/Android. Connect your favourite corded headphones to the GO blu and then tuck it away – it’s so petite it will slip into your running gear or suit pocket. It’s also gorgeous enough to show off by leaving it on the table at your favourite coffee shop!

    GO blu. Go beyond.

    With its lightweight, soft-touch polymer enclosure (great for Bluetooth reception, unlike signal-blocking metal), copper-coloured trim and ChronoDial watch crown-style control, the GO blu is a pleasure to use wherever you go. iFi has even incorporated a high-quality chip-based (CMOS-MEMS) microphone, enabling hands-free calls, voice chat for gaming and access to voice assistants such as Apple Siri and Google Assistant.

    Wired Connection

    Further flexibility is provided by the USB-C charging port, which doubles as an audio input enabling USB connection from source devices that don’t offer Bluetooth connectivity. Hi-res PCM audio data up to24-bit/96kHz is supported when the GO blu is connected in this way.

    HD Bluetooth 5.1

    The way iFi implements Bluetooth is anything but ‘run of the mill’ and despite its diminutive size the GO blu is no exception. The use of Qualcomm’s latest four-core QCC5100 Bluetooth processing chip ensures that every current high-definition Bluetooth audio format is supported.

    Swiss Chronograph design

    GO blu‘s ChronoDial is 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. The GO blu boasts a Balanced 4.4mm output enabling headphones equipped with balanced connectivity to take full advantage of the GO blu’s balanced amp design.

    S-Balanced circuitry

    In addition, the 3.5mm output benefits from iFi’s proprietary S-Balanced circuitry. 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

    With XBass to add back lost low-end grunt and XSpace to widen the soundstage, the GO blu is small on the outside but mighty on the inside. You will be immersed in its majestic musicality. Even phone calls are ‘clear Voice capture’ using Qualcomm’s ANC technology. Clear, crisp and no annoying echo. The X-factor doesn’t stop with the sound. The GO blu has a watch crown-style control and is made with hi-tech components.
