iFi Audio Go Blu AirPortable DAC Headphone Amplifier CS43131 Bluetooth 5.2 aptX Adaptive LDAC LHDC 

iFi Audio GO BLU AIR


The iFi Audio GO Blu Air is a portable Bluetooth DAC and headphone amplifier designed to follow you everywhere. Both practical and high-performance, it features a magnetic clip for easy transport on the go. Powered by its Qualcomm QCC5144 chip dedicated to Bluetooth 5.2, the Go Blu Air offers high-performance audio reception, thanks in particular to its support for a variety of codecs (LDAC, LHDC, aptX, etc.), as well as its Circus Logic CS43131 DAC chip.

The Go Blu Air is connected via its two outputs: a 3.5mm jack using S-Balanced technology and delivering up to 165mW at 32Ω, and a second balanced 4.4mm jack delivering up to 262mW at 32Ω. Power is supplied via a USB-C port, which charges the battery and provides up to 10 hours of battery life.

iFi Audio Go Blu Air: A high-performance DAC

The Go Blu Air’s unique design reveals the components essential to its performance, each one separate and dedicated to a specific task. Its Qualcomm QCC5144 chip handles Bluetooth reception, while the Cirrus Logic CS43131 DAC chip handles signal conversion. A dual-stage amplifier handles a balanced 4.4mm jack output of up to 256mW/5.6V as well as an S-Balanced 3.5mm jack output. The GMT clock system, meanwhile, enables a drastic reduction in jitter. Finally, XBass and XSpace technologies deliver punchy bass and an immersive soundstage, respectively.

The inclusion of Bluetooth 5.2 connectivity enables convenient wireless use. It supports high-performance codecs such as LDAC, LHDC, and aptX.

iFi Audio Go Blu Air: A portable design

The Go Blu Air comes with a detachable magnetic clip, allowing you to carry it safely and easily by attaching it to a belt, bag or pocket; thanks to its lightweight design, weighing just 30g, it won’t get in the way.

In addition, it features a MEMS microphone with noise cancellation powered by Qualcomm technology, enabling clear hands-free calls. Its rotary knob allows you to adjust the volume by turning it. A short press controls play/pause, as well as fast-forward and rewind. Finally, a long press of the button activates the voice assistant on the connected smartphone.

Great and small device
Great device, tested out only the 3.5mm jack. Plays loudly and cleanly on Crinacle zero Red.
The only drawback is that the volume wheel ignores input if turned too quickly. About 1 revolution per second is its maximum speed, anything faster and the volume barely moves, so you need to be patient when you need to adjust the volume quickly
