KAIY C41S Bluetooth Transmitter Receiver Dual Headphones AUX Optical

Dual Headphone Transmitter Receiver

The KAIY C41S is a 3-in-1 Bluetooth adapter that operates as both a transmitter and a receiver. It streams TV audio to two pairs of wireless headphones simultaneously or adds wireless streaming to a wired stereo system. The unit connects via optical or 3.5 mm AUX ports and includes the necessary cables for immediate setup.

Optical AUX Interface Limits

Optical and 3.5 mm AUX connections carry stereo audio only, so multichannel formats are downmixed to two channels. The adapter requires a 5 V DC power source to operate. Low-latency playback depends on the connected headphones supporting the same low-latency decoding; standard headphones will introduce a noticeable delay. Apple AirPods are explicitly not supported by this device.

Replaces Wired Headphone Splitters

This adapter replaces a wired headphone splitter or long cable runs between a TV and two listeners. It also upgrades a traditional stereo receiver by adding Bluetooth input without new wiring. The jump is worth it when you need private late-night viewing for two people or want to stream music from a phone to an older amplifier. The bypass feature in receiver mode keeps the stereo connected to other sources without cable swapping.
