Miniature Bluetooth DAC

The Go Blu connects wirelessly to your smartphone, tablet or other Bluetooth source and delivers hi-res audio through wired headphones. It's particularly useful for devices that lack a headphone socket or have a poor-quality built-in output.

Use your choice of quality headphones

The Go Blu offers a 3.5mm single-ended output for standard headphones and a 4.4mm balanced output for more specialised designs. With up to 5.6V output, it has enough power for even demanding, current-hungry headphones.

Supports a wide range of Bluetooth audio codecs

Powered by the Qualcomm QCC5100 chipset, the Go Blu supports aptX, aptX HD, aptX Adaptive, aptX LL, LDAC, LHDC/HWA, AAC and SBC. If you prefer a wired connection, the iFi Audio Go Bar is another portable option in the Go range.

Dual-mono circuit for superb staging

The Go Blu uses a dual-mono circuit design, dedicating a separate signal path to the left and right channels. This delivers better channel separation, reduced distortion and a more holographic sound.

USB-C for charging and audio input

The USB-C port handles both recharging and digital audio input at up to 24-bit/96kHz. The built-in battery provides up to 10 hours of use before recharging is needed, and sources without Bluetooth can connect directly over USB.

XBass and XSpace sound programmes

XBass applies an analogue bass boost to enhance low frequencies without affecting the mid-range. XSpace is an analogue headphone spatialiser that widens the soundstage for a more open, enveloping listen.

Built-in mic for hands-free calls

A built-in microphone lets you take calls through your headphones without reaching for your phone. Leave your device in a bag and handle calls directly via the Go Blu.
