Versatile Bluetooth 5.4 Audio Adapter

The IHDAPP Z3#Q2702_B adds wireless streaming to any device with a 3.5 mm AUX, RCA or USB port. It operates as both a transmitter and a receiver, so you can send audio from a TV to headphones or stream music from a phone to a wired speaker. Bluetooth 5.4 provides a stable link up to 20 metres without obstacles. The compact unit includes an LCD screen and a multi-function button for hands-free calls.

Replaces Wired Connections and Older Adapters

This unit removes the need for physical cables between a source and a speaker or headphones. It upgrades systems that lack Bluetooth entirely or that rely on earlier versions with shorter range. The jump is worth it when you want dual-phone pairing, USB stick playback up to 32 GB, or FM transmission between 76 and 108 MHz. It does not suit buyers who need aptX HD or LDAC codec support.

Simple Setup with a Few Caveats

No driver installation is required; pair the device using the multi-function button and the LCD status screen. Charge the 400 mAh battery via the included Type-C cable in about one hour for up to 6.5 hours of transmitter use. The 3.5 mm and RCA cables are supplied. Users sometimes forget to switch the TX/RX slider, causing pairing failures, and the FM function can be noisy in dense urban areas.
