ESTONE AX-03 Bluetooth 4.1 Receiver

The ESTONE AX-03 is a compact Bluetooth 4.1 receiver that adds wireless audio to any device with a 3.5mm jack. It targets listeners who want to use their favourite wired headphones or car audio systems without cables. The clip-on design keeps it secure during sport or daily commuting. It supports simultaneous pairing with two mobile phones or tablets.

60mAh Battery Up to Six Hours Talk Time

A 3.7V 60mAh battery delivers up to six hours of talk time on a single charge. That capacity covers a typical workday of calls or a long gym session with music streaming. Extended listening at higher volumes will drain the cell faster, so overnight charging is practical for daily users. The unit does not operate while plugged in.

Bluetooth 4.1 2.4GHz Interface Limits

Bluetooth 4.1 on the 2.4GHz band provides stable streaming within roughly ten metres in open space. Walls, bodies and other 2.4GHz devices reduce reliable range and can cause dropouts. The receiver handles A2DP, AVRCP, HFP and HSP profiles for stereo audio and call control. It cannot transmit audio to two headphones at once.
