It supports Bluetooth 5.2 as well as high-resolution codecs like aptX, LDAC, LHDC, and AAC, ensuring lossless transmission across nearly all devices, from Android smartphones and iPhones to tablets and third-party transmitters.

These enable a sound profile typically reserved for stationary HiFi components. Through the balanced 4.4mm output, the GO blu Air delivers up to 262 mW of power at 32 ohms. The 3.5mm S-Balanced output minimizes distortion and crosstalk, making it ideal for sensitive in-ear monitors. Two analog sound modes—XBass and XSpace—allow for personalized adjustments of bass intensity and spatiality, which can be combined at the touch of a button. The integrated MEMS microphone technology with noise cancellation ensures clear voice quality during calls, voice chats, or when controlling voice assistants. Weighing only 31g and smaller than a car key, the GO blu Air seamlessly integrates into everyday life. The magnetic clip provides secure attachment to clothing or bags. With a battery life of up to ten hours, it is the perfect companion on the go. The device is controlled via an intuitive dial that allows for precise volume control and playback management.
