The Lindy 3.5mm & TosLink (Optical) Audio Wireless Audio Transceiver is a compact, multi-function solution for connecting non-wireless audio devices wirelessly to sources and outputs with Wireless audio connectivity. 3.5mm and TosLink (Optical) input ports allow for the connection of non-Wireless audio source devices such as TVs, amplifiers and laptops, this transceiver can then transmit a high-quality audio signal wirelessly to wireless audio headsets, soundbars or speaker setups. This provides a great wireless working from home setup when used with a compatible headset or earphones or alternatively allows for cable-free AV connections in residential setups. The devices transceiver functionality also allows for this unit to act as a wireless audio receiver with a simple push of the switch. This allows users to connect non-wireless audio output devices such as headphones, older speakers & amplifiers, or car stereo systems to a wireless audio source device including smartphones and tablets. Qualcomm aptX™ low latency and aptX™ codec support provide clear, high quality audio while limiting delay between the source and output for an excellent synchronized listening experience. This codec also provides the ability to transmit audio signals to two wireless audio audio devices simultaneously, for shared listening of music or video content in the home or office. Qualcomm aptX is a product of Qualcomm Technologies, Inc. and/or its subsidiaries. Qualcomm is a trademark of Qualcomm Incorporated, registered in the United States and other countries. aptX is a trademark of Qualcomm Technologies International, Ltd., registered in the United States and other countries. Wirelessly connects non-wireless audio source devices to wireless speakers and headphones. Alternatively, connect smartphones and tablets to non-wireless output audio devices. 3.5mm and TosLink (Optical) connections for use with a wide variety of source and audio devices. aptX™ low latency and aptX™ codec support for crystal clear, synchronised audio. 2-year warranty.
The Lindy Wireless Audio Transceiver is for anyone looking to add wireless audio capabilities to their existing devices, whether transmitting audio from a TV or receiving it on older speakers. Its key benefit is offering versatile wireless connectivity via both 3.5mm and TosLink (Optical) ports, supporting Qualcomm aptX™ low latency for synchronized audio. A potential caveat is that it requires compatible wireless audio devices to function as either a transmitter or receiver.

FAQs
Can this device connect to any Bluetooth headphones?
It can connect to most Bluetooth-enabled headphones. For the best experience with minimal delay, use headphones that support the Qualcomm aptX™ or aptX™ Low Latency codecs.
What is the range of the wireless connection?
The wireless range is typically up to 10 meters (33 feet) in open space, but this can be affected by obstructions and interference from other wireless devices.
Do I need to buy separate cables?
Yes, this product includes a USB Type-C cable for power, but it does not include audio cables (3.5mm or TosLink). You will need to provide these separately based on your source and output devices.
Can I use this in my car?
Yes, you can use it in receiver mode. Connect the transceiver's 3.5mm output to your car stereo's auxiliary input and pair your smartphone or tablet to stream music wirelessly.
How do I switch between transmitter and receiver mode?
There is a physical switch on the device labeled 'TX' (Transmitter) and 'RX' (Receiver). Simply slide the switch to your desired mode.
Does this device require its own Bluetooth pairing?
Yes, when using it as a transmitter, you pair your Bluetooth headphones/speakers to the transceiver. When using it as a receiver, you pair your audio source (smartphone, tablet) to the transceiver.
What is the warranty period?
The Lindy Wireless Audio Transceiver comes with a 2-year warranty.
Troubleshooting
No audio output when transmitting
Ensure the wireless headphones/speaker are powered on, in pairing mode, and successfully paired with the transceiver. Check that the audio source device is sending an audio signal and that the transceiver is powered via USB.
No audio input when receiving
Verify that your smartphone or tablet is connected via Bluetooth to the transceiver and that audio playback is active. Ensure the transceiver is in Receiver mode and connected to a powered USB source.
Audio delay or stuttering
Confirm that both the transmitter (source) and receiver (transceiver or output device) support aptX™ Low Latency for the best synchronization. Reduce the number of active Bluetooth devices nearby. Ensure a stable USB power supply.
Transceiver not powering on
Check that the USB Type-C cable is securely connected to both the transceiver and a functional USB power source. Try a different USB port or power adapter.
Cannot pair a second device
Ensure your wireless audio devices support simultaneous connections. Refer to the transceiver's manual for specific instructions on initiating dual pairing.
