ELEGIANT Bluetooth 5.0 Transmitter Receiver Wireless Audio Adapter Pair 2 Headphones at Once aptX HD/aptX LL Built-in Microphone LED Indicator, Optical TOSLINK 3.5mm AUX RCA for TV Home Stereo System

Some tips: 1. Not recommend for streaming live music (while playing guitar, keyboard, electronic drums, etc. ) 2. Many headphones/speakers (e. g. Bose, Beats, Sony) are primarily for music, not watching TV and do not support aptX-LL. 3. For TV optical output - set audio format to PCM. Dolby / DTS is not supported. 4. For many models of TV, the built-in speakers might not work if you choose to use an external speaker. They will either automatically mute when you plug something into an audio output port (AUX, RCA, Optical, etc. ) or they become disabled once you choose "External Speakers" as your TV's audio output. Some newer TVs however, allow you to play audio from both the TV's internal speakers and an external audio device simultaneously. For example the newer LG TVs with WebOS versions 3.0 and 3.5 have this feature but Samsung TVs still do not. In the LG TV WebOS 3.0 / 3.5 example, you can enable this feature by changing the TV AUDIO OUT setting from "Internal TV Speaker" to “Internal TV Speaker + Optical”.

1. Transmitter Mode In TX transmitter mode, the Bluetooth Adapter can be plugged into the audio output jack on TVs, PC, computers, iPods, AV receiver and other non-Bluetooth audio sources, and paired to Bluetooth headphones / speakers, e. g. Bose, Beats, Sony, Plantronics, Apple AirPods headphones. 2. Receiver Mode In RX Bluetooth receiver mode, the Bluetooth Adapter can be paired to cellphones, iPads, Echo, Echo Dot or other Bluetooth audio sources, and plugged into wired speakers headphones to stream audio from cellphones to the wired stereos. 3. If you use TOSLINK to connect our transmitter to your TV but there are problems like no sound (like Samsung, Sony TV), please set your
TV following these steps: 1. Find "Sound Output Speakers" in Settings. Then select ""External speakers". 2. Find "Audio Format". 3. Select "PCM". 4. Another 2 cable connection, if there are problems like no sound, please follow these steps and check. 1. 3.5 mm Audio Cable connection, please change TV audio channel to "Headphones". 2. RCA R/L Audio Cable connection, please change the audio channel to "external speaker". More Audio Connection Option ELEGIANT Bluetooth adapters equipped with the digital optical and AUX interface, with TOSLINK SPDIF cable, 3.5 mm AUX and RCA audio cable, provide you more options.
