Frequently Asked Questions
Q: What is the difference between Receiver (RX) and Transmitter (TX) mode on this Bluetooth audio adapter?
A: In Receiver (RX) mode, the adapter connects wirelessly to a Bluetooth-enabled smartphone or tablet and outputs audio to a wired speaker or amplifier via 3.5mm AUX or optical output — essentially adding Bluetooth capability to any wired audio system. In Transmitter (TX) mode, it connects to a non-Bluetooth audio source (like a TV or CD player) via AUX or optical input and streams the audio wirelessly to Bluetooth headphones or speakers. You can connect up to two Bluetooth headsets simultaneously in TX mode.
Q: Can this Bluetooth receiver transmitter play music directly from a USB flash drive?
A: Yes! This adapter supports direct USB flash drive playback. Simply insert your USB drive loaded with audio files (MP3, WAV, FLAC, APE, M4A, ALAC, WMA, AMR) and the OLCD screen will display song information for easy browsing and control — no phone or streaming app needed.
Q: Does this audio adapter support high-quality lossless audio codecs?
A: Absolutely. The adapter supports aptX, aptX-HD, aptX-LL, aptX-AD, AAC, and SBC codecs — covering everything from standard Bluetooth audio up to hi-res wireless streaming. The aptX-LL codec provides ultra-low latency, which is especially useful for watching video without audio lag. The optical input supports sampling rates up to 192kHz / 24-bit for true hi-fi digital audio.
Q: How long does the battery last, and how does it charge?
A: The built-in 1200mAh lithium battery provides approximately 38 hours of playback in Receiver mode and 42 hours in Transmitter mode, with up to 30 days of standby. A full charge takes only about 1.5 hours via the included Type-C cable (5V/1A input).
Q: Is this Bluetooth audio adapter compatible with my TV, phone, or home stereo?
A: Yes — it's designed for broad compatibility. It works with Android and iOS smartphones and tablets, smart TVs, CD/DVD players with optical or AUX outputs, active speakers, stereo amplifiers, and any Bluetooth headphones or speakers that support the A2DP profile. No app download or driver installation is required.
