Home Audio Upgrade Seekers

This adapter suits users who want to stream audio from a phone to wired speakers or send TV sound to Bluetooth headphones. It is not for setups requiring aptX HD or LDAC codec support. Buyers needing simultaneous multi-device pairing or optical digital inputs should look elsewhere.

Bluetooth 5.0 Connectivity

The single specification that decides fit is the Bluetooth 5.0 radio paired with a 3.5mm analogue jack. It determines which source devices can connect and what cables are required. Verify your equipment has a compatible 3.5mm port before purchase.

Questions about this item

What audio output must my TV or speaker have to connect the KN321's 3.5 mm cable?

The KN321 uses a 3.5 mm AUX jack, so the source device needs a matching 3.5 mm audio output or a compatible RCA-to-3.5 mm adapter.

Will the KN321's Bluetooth 5.0 connection work with my older Bluetooth headphones or car stereo?

Yes, Bluetooth 5.0 is backward compatible, so the adapter can pair with legacy headphones, speakers or car stereos that use earlier Bluetooth versions.

How do I confirm the KN321 is powered on and streaming audio after setup?

Press the power button until the LED lights up; the illuminated LED shows the unit is active and ready to transmit or receive audio.
