Will this work with a regular TV?

As long as your TV has an AUX audio output jack, the Relay will work with it.

Will I get audio lag or lip-sync delays with my headphones?

Your headphones must support either aptX Low Latency or aptX Adaptive in order to eliminate audio latency. Please note that most true wireless earbuds (such as AirPods) do not currently support these audio codecs.

How are the volume levels?

You should be able to reach sufficient volume levels by adjusting the volume on both the Relay, your headphones, and / or the audio source.

How long does it take to fully charge the adapter?

It only takes 1.5 hours to fully charge the adapter.

Can I connect my phone to the Relay via Bluetooth?

No, as a transmitter, the Relay is designed to only connect to audio devices (such as your headphones or AirPods) via Bluetooth.
