Connect Bluetooth audio to a TV by using the built-in pairing menu on modern smart TVs or adding an external Bluetooth transmitter to older models.
Modern TVs from Samsung, Sony, TCL, and Hisense include Bluetooth for wireless audio output, but many older and budget sets don’t. The fix depends entirely on your TV’s generation — use the direct pairing method below for smart TVs, or the external transmitter route for everything else. If you’re shopping for a new set, our roundup of the best Bluetooth-capable TVs covers models with the smoothest wireless audio support.
Built-In Bluetooth: The Direct Pairing Route
If your TV runs Google TV or Android TV (common on TCL, Sony, and Hisense sets), native Bluetooth pairing takes about a minute. Press Home on the remote, open Settings (the gear icon), select Remote and Accessories, then Add Accessory. Put your headphones or speaker into pairing mode — the light should flash — pick it from the list, and confirm Pair.
For Samsung Smart TVs from 2016 onward, go to Settings > Sound > Sound Output or Bluetooth Speaker List. Select Add New Device, choose your headphones or speaker, then manually switch the audio output to Bluetooth. Samsung’s official Bluetooth audio pairing guide walks through the same steps.
Most modern LG, Vizio, and Sony TVs also support Bluetooth audio. If you don’t find a Bluetooth option in your TV’s sound or accessory menus, your set likely lacks the necessary hardware — the external transmitter method below is the fix.
Adding Bluetooth To Older TVs: External Transmitters
For any TV without built-in Bluetooth audio, a Bluetooth audio transmitter plugged into the TV’s audio output does the job. You need a transmitter that supports TX (Transmit) mode — most compact Bluetooth 5.0 adapters work — plus an audio cable and USB power.
What you need:
- Bluetooth audio transmitter (TX mode required)
- Audio cable: 3.5mm, RCA-to-3.5mm, or optical with a DAC
- USB power source (TV’s USB port or wall adapter)
Setup:
- Set the transmitter to TX mode — RX mode receives audio and will not work
- Connect the audio cable from the TV’s headphone or audio-out jack to the transmitter’s input
- Power the transmitter via USB
- Put your headphones or speaker in pairing mode
- Select the transmitter’s name on your audio device — a steady light confirms the link
If your TV has only an optical port, add a digital-to-analog converter (DAC) between the TV and transmitter to convert the signal.
| Method | Best For | Setup Time |
|---|---|---|
| Built-in Bluetooth | Modern smart TVs (2016+) | 1-2 minutes |
| External transmitter | Older TVs without Bluetooth | 5-10 minutes |
| Transmitter + DAC | Optical-only TVs | 10-15 minutes |
| Low-latency transmitter | Reducing lip-sync delay | 5-10 minutes |
Avoiding The Most Common Pairing Frustrations
A few things trip people up regularly:
TX vs RX mode. The transmitter must send audio, not receive it. A transmitter left in RX mode pairs to a phone but won’t pull audio from the TV. Flip the switch to TX before starting.
USB power noise. Some TV USB ports introduce static into the audio. If you hear buzzing, unplug the transmitter’s USB and plug it back in, or use a dedicated wall adapter.
Audio lag. Bluetooth adds a small delay that can cause lip-sync issues. Low-latency transmitters help but require compatible headphones — check specs before buying.
Manual output selection. On Samsung and some other TVs, pairing a Bluetooth device doesn’t automatically reroute the audio. You still need to go to Settings > Sound > Sound Output and pick Bluetooth.
FAQs
Can any Bluetooth headphones work with a TV?
Most modern Bluetooth headphones using the A2DP profile work with TVs that support Bluetooth audio output. Samsung and Google TV models generally accept standard wireless headphones and speakers. Check your TV’s specs to confirm Bluetooth audio output support — some older TVs only support Bluetooth for remotes, not audio.
Why is the audio out of sync with the picture?
Bluetooth adds a small delay that varies by transmitter and headphones. Low-latency codecs like aptX Low Latency reduce the lag noticeably, but both the transmitter and headphones must support the same codec. A wired connection or a dedicated low-latency transmitter pair eliminates the sync issue entirely.
Can I use Bluetooth without a smart TV?
Yes. A Bluetooth audio transmitter plugged into your TV’s headphone or audio-out port works on any TV, smart or not. The transmitter handles the wireless connection independently — the TV simply sends audio through the cable, so no smart features are required.
