Dual-mode Bluetooth 5.4 adapter

The IHDAPP Z3#Q2770_B adds wireless audio to any device with a 3.5 mm aux port. It works as a transmitter to send sound from a TV or plane seat to Bluetooth headphones, and as a receiver to stream music from a phone to wired speakers or car audio. The compact dongle draws power from its built-in rechargeable battery.

Plug-and-play audio bridge

No drivers or software are required; the adapter pairs by holding the multifunction button until the indicator flashes. A single USB cable recharges the unit, delivering up to 14 hours of playback in receive mode and up to 11 hours in transmit mode. Both modes support simultaneous pairing with two Bluetooth devices.

Upgrade from single-role dongles

Separate transmitter-only or receiver-only adapters force you to carry two gadgets for different scenarios. This 2-in-1 design replaces both, so one device covers airline entertainment, home TV listening and car stereo streaming. The jump is worth it whenever you regularly switch between sending and receiving audio over Bluetooth 5.4.
