Versatile Bluetooth 5.0 Adapter

The Golvery BTI-038 is a 2-in-1 transmitter and receiver that adds wireless audio to non-Bluetooth sources. In TX mode it sends sound from a TV, PC or MP3 player to headphones or speakers. In RX mode it streams audio from a phone or tablet to wired speakers, home theatre systems or car audio.

Dual-link sharing for two listeners

The adapter pairs with two Bluetooth headphones in TX mode so two people can watch together without disturbing others. In RX mode it connects to two source devices and lets you switch between them. Buyers who need aptX Low Latency or aptX HD codecs should look elsewhere, as only SBC is supported.

25-hour battery with optical and analogue inputs

A full charge provides up to 25 hours of playtime from the built-in battery. Connections include 3.5 mm aux, RCA and optical digital for wide compatibility. Latency sits around 70 ms with SBC low-latency headphones, rising to roughly 220 ms with standard headsets.
