Transmitter Receiver Bypass Modes

The ifofo BT17S operates as a Bluetooth 5.3 transmitter, receiver or bypass adapter. In transmitter mode it sends audio from a non-Bluetooth TV or PC to wireless headphones. Receiver mode streams phone or tablet audio to wired speakers. Bypass mode passes TV sound directly to a stereo without wireless pairing.

Dual Antenna And LCD Display

Two external antennas extend the wireless link for more stable coverage around the home. The built-in LCD shows the active mode and connection status at a glance. Front-panel buttons let you switch between transmitter, receiver and bypass functions without navigating menus on the source device.

For Sharing TV Audio Wirelessly

Buyers who want to listen to television through two Bluetooth headphones at once will find the dual-pairing feature useful. Households that need aptX Adaptive or LDAC codec support should look elsewhere, as the specifications list only standard Bluetooth 5.3 audio. Users requiring simultaneous optical and RCA connections must choose one input, because the unit cannot accept both at the same time.

Questions about this item

Will the 3.5 mm AUX port or optical input wear out and need replacement?

The AUX, RCA and optical ports are passive connectors with no moving parts; they do not have a scheduled replacement interval.

What limits continuous streaming — the Bluetooth 5.3 range or the dual-antenna signal?

The dual-antenna design extends the Bluetooth 5.3 link, so the practical limit is the wireless environment rather than the adapter itself.

Does the LCD screen or the 5 V power draw create noticeable heat during all-day use?

The unit runs on 5 V with a small LCD; it stays cool to the touch even during extended sessions.
