LUOM AX-03 Wireless Audio Adapter

The LUOM AX-03 is a compact post-hook type receiver that adds wireless audio capability to any headphone or speaker equipped with a 3.5mm jack. It clips onto clothing for portable use and is sold in a green finish. The unit operates on a built-in 3.7V 60mAh battery.

Who this suits and who it does not

Listeners who want to keep their favourite wired headphones while streaming music or taking calls from a phone or tablet will find this adapter practical. It also serves users who need simultaneous pairing with two Bluetooth sources. Buyers who require aptX or LDAC codec support should look at other solutions. Those needing a transmit mode for non-Bluetooth sources will not be served by this receive-only device.

Deciding specification

The universal 3.5mm jack is the single specification that determines compatibility; any headphone, car auxiliary input or speaker with that socket will work immediately. The receiver supports A2DP, AVRCP, HFP and HSP protocols for stereo audio and hands-free calls. Sensitivity is rated at 118dB S.P.L. at 1KHz for clear playback volume.

Questions about this item

Does the 3.7 V 60 mAh battery run warm or make any noise during all-day use?

The receiver draws very little power from its 3.7 V 60 mAh cell, so it stays cool and silent even after hours of continuous playback.

What must I already own to use the 3.5 mm jack on this adapter?

You need a pair of wired headphones, earphones or speakers that plug into a standard 3.5 mm stereo socket.

Will the 118 dB sensitivity work well with older wired headphones I still keep?

Yes — the 118 dB S.P.L. rating means even vintage or low-efficiency models will play loudly enough without extra amplification.
