Overview

The Hosa IBT-402 Drive Bluetooth Audio Interface is designed to bridge the gap between wired audio equipment and wireless convenience. In transmitter mode, it connects to any device with a 3.5mm headphone jack—such as a TV, older stereo, or in-flight entertainment system—and sends audio wirelessly to Bluetooth headphones or speakers. In receiver mode, it accepts a Bluetooth signal from a smartphone or tablet and outputs audio through its 3.5mm connector to wired speakers or a car stereo. This dual functionality makes it a versatile tool for a variety of everyday audio scenarios.

Under the hood, the IBT-402 runs on Bluetooth 4.2 and supports aptX, A2DP, and AVRCP profiles, delivering better-than-basic audio quality for music and media playback. The built-in 200mAh battery provides up to 8 hours of use in transmitter mode and 6 hours as a receiver, recharging fully in about 2 hours via DC 5V. Its compact form factor is easy to slip into a pocket or leave connected to equipment without being obtrusive, making it a practical choice for adding wireless audio to gear that was never designed for it.
