Corn Electronics Bluetooth Transmitter Receiver aptX LL 8670 3.5mm Optical

Dual-Mode Audio Adapter

The Corn Electronics 8670 is a 2-in-1 Bluetooth transmitter and receiver built around a CSR8670 chipset. It switches between TX mode for sending TV or player audio to wireless headphones and RX mode for streaming phone or tablet music to a wired stereo system. The unit is new and supports aptX and aptX Low Latency in both directions for CD-quality sound with minimal lip-sync delay.

Connection Flexibility & Limits

It suits users who want one device to add Bluetooth to an older hi-fi and to make a non-Bluetooth TV wireless for late-night viewing. Optical TOSLINK, 3.5 mm aux and RCA via the supplied adapter give three wired hook-up options. Buyers who need simultaneous use of optical and analogue inputs should look elsewhere because the adapter does not function as an audio converter and cannot run those connections at the same time.

aptX Low Latency in Both Modes

The decisive specification is aptX Low Latency support in both transmitter and receiver modes, which keeps audio-video sync tight enough for film and gaming when paired with compatible headphones or speakers. Without aptX LL on the receiving end the low-latency benefit is lost, so check your headphones or speakers before purchasing.
