Blue Bluetooth 4.1 Receiver

The ESTONE AX-03 is a compact Bluetooth 4.1 receiver that adds wireless audio to any device with a 3.5 mm jack. It clips on and pairs with headphones or speakers for cable-free listening and calls. The built-in 3.7 V 60 mAh battery delivers up to 6 hours of talk time.

Commuters and gym users seeking wireless freedom

Ideal for people who want to use existing wired headphones without cables while on the move. It supports simultaneous pairing with two phones for easy switching. Not suited for buyers who need aptX or LDAC codecs, longer battery life, or a built-in microphone boom for noisy environments.

Bluetooth 4.1 with dual-device pairing

The single specification that decides fit is Bluetooth 4.1 with A2DP, AVRCP, HFP and HSP profiles plus the ability to maintain two active connections. If your source device or headphones require a newer Bluetooth version or specific high-resolution codecs, this adapter will not meet that need.
