How to connect a Bluetooth speaker to a TV without Bluetooth

Plug a Bluetooth transmitter into the TV’s optical output and pair the speaker with it. It must be a transmitter (it sends sound out), not a receiver. Bluetooth adds a small delay between picture and sound, which some people notice on speech.

Yes. You need a converter.

What you need

Optical (TOSLINK) cable Look for: TOSLINK to TOSLINK $6–$12
Bluetooth transmitter with optical input Look for: Bluetooth transmitter, optical input, aptX Low Latency $30–$50, needs USB or wall power

Connect it like this

TV (no Bluetooth audio)Optical audio (TOSLINK) out
Optical (TOSLINK) cable
Bluetooth transmitter with optical inputOptical audio (TOSLINK) in, Bluetooth out. Needs power.

What to know

Difficulty: Easy
Cost: About $36–$62 if you buy everything new
Sound: Good. Bluetooth compresses the audio a little
Lag: Some. Noticeable in fast games or lip-sync
Extra power: Yes, the converter needs USB or wall power

Why this works

Optical audio (TOSLINK) and Bluetooth use different signal formats, so a Bluetooth transmitter with optical input converts between them.

Good to know

Many "HDMI only" TVs still have a small AV input hidden on the side. Press Input/Source on the remote and look for AV or Composite.
