To add Bluetooth to a TV that lacks it, the most reliable solution is to use an external Bluetooth transmitter that plugs into your TV's audio output, not a USB dongle. Most modern smart TVs already have Bluetooth built-in, so first check your TV's settings menu, if you see options for "Bluetooth" or "Sound Output," you're already set and just need to pair your device. If you later experience choppy playback, you can stop Bluetooth audio stuttering on smart TV by reducing wireless interference.
How to add Bluetooth to your TV: built-in vs. external options
Bluetooth is typically a built-in feature in most modern smart TVs, rather than something that needs to be "installed." If your TV is from the last few years, it almost certainly has Bluetooth for connecting wireless headphones, soundbars, or speakers. However, if you own an older model or a budget TV without this feature, you cannot simply plug a USB Bluetooth dongle into the TV's USB port, that port is usually for media storage or power, not for adding wireless audio. Instead, you need an external Bluetooth transmitter that connects to your TV's audio output (optical, RCA, or 3.5mm jack). This device captures the audio signal and broadcasts it wirelessly to your headphones or speaker. If your TV already has Bluetooth, you can skip the transmitter and directly connect Bluetooth speaker to Vizio smart TV models or similar sets.
Check if your smart TV already has Bluetooth
Before buying anything, verify whether your TV has built-in Bluetooth. Navigate to the settings menu and look for options related to "Bluetooth," "wireless devices," "accessories," or "sound output." Here are the exact paths for the most common brands:
- Samsung (2016, present): Settings > Sound > Sound Output > Bluetooth Speaker List. For input devices like keyboards or gamepads, go to Settings > General > External Device Manager > Input Device Manager > Bluetooth Device List.
- LG (webOS 6.0 or later): Settings > All Settings > Sound > Sound Out > Use Wireless Speaker > Bluetooth Devices > Connectable Devices. For input devices: Settings > All Settings > General > External Devices > Connect Bluetooth Controller > Connectable Devices.
- Sony Android/Google TV: Settings > Remotes & Accessories > Pair accessory, then select your device from the list.
- Roku devices with Bluetooth (Roku Ultra, Streambar, Select/Plus/Pro Series TVs): Home > Settings > Remotes & devices > Wireless headphones > Add new wireless headphones.
If you find any of these menus, your TV has Bluetooth. If not, proceed to the external transmitter solution below.
How to connect a Bluetooth device to your smart TV's built-in radio
Once you've confirmed your TV has Bluetooth, pairing a device is straightforward. Follow these steps for a smooth connection:
Step 1: Put your audio device into pairing mode
Most Bluetooth devices require you to hold a Bluetooth or power button until a light blinks rapidly. This makes the device discoverable. Check your device's manual if you're unsure, this is the most common reason pairing fails.
Step 2: Navigate to your TV's Bluetooth settings
Use the menu paths listed above for your specific TV brand. For Samsung, go to Settings > Sound > Sound Output > Bluetooth Speaker List. For LG, go to Settings > All Settings > Sound > Sound Out > Use Wireless Speaker > Bluetooth Devices. For Sony, go to Settings > Remotes & Accessories > Pair accessory.
Step 3: Select your device from the list
Your TV will scan for nearby devices in pairing mode. When your headphones or speaker appears, select it.
Step 4: Confirm the connection
Once paired, the TV will switch audio output to the Bluetooth device automatically. Play a video to test. If you don't hear sound, go back to the sound output settings and select your Bluetooth device as the active output.
Add Bluetooth to any TV with an external transmitter
If your TV lacks built-in Bluetooth, an external Bluetooth transmitter is the only practical way to add wireless audio. This small device plugs into your TV's audio output and broadcasts the sound to any Bluetooth headphones or speaker.
What you need to know about Bluetooth transmitters
These transmitters come in two main types: one with a 3.5mm aux cable (for TVs with a headphone jack) and one with an optical (TOSLINK) cable (for TVs with digital audio out). Some models include both. Choose one that matches your TV's available audio output. If your TV has neither, you can use an RCA-to-3.5mm adapter, but note that RCA outputs are often fixed-volume and may not work with all transmitters.
How to connect the transmitter to your TV
Plug the transmitter into your TV's audio output port. If using optical, remove the protective cap on the cable and insert it firmly until it clicks. If using 3.5mm, plug it into the headphone jack. Power the transmitter via its USB cable, you can plug it into the TV's USB port for convenience, though a wall adapter is more reliable.
Pairing the transmitter with your headphones or speaker
Put your Bluetooth device into pairing mode (hold the Bluetooth button until the light blinks). Then press the pairing button on the transmitter. The two devices will connect automatically within a few seconds. Once paired, the transmitter will remember the device and reconnect next time you power both on.
Note: Some transmitters support dual-device pairing, allowing two headphones to connect simultaneously, great for watching TV with a partner.
Troubleshooting common Bluetooth TV connection problems
If your Bluetooth device won't connect or keeps dropping audio, try these actionable fixes:
- Ensure pairing mode is active: Most Bluetooth devices exit pairing mode after 30-60 seconds. Re-enter pairing mode on both the TV and the device, and keep them close together during the process.
- Check distance and obstructions: Bluetooth range is typically up to 30 feet, but walls and furniture can reduce this. Move the device closer to the TV and eliminate obstacles.
- Disconnect from other devices: If your headphones or speaker are already paired to a phone or tablet, they won't connect to the TV. Go to the device's Bluetooth settings and disconnect or unpair it from other gadgets.
- Restart both devices: Turn off your TV and the Bluetooth device, wait 10 seconds, then power them back on. This clears temporary glitches.
- Check for multi-device limitations: Some Samsung Smart TVs manufactured from 2022 can connect to two Bluetooth devices simultaneously. If you're trying to connect a second device, disconnect the first one first.
- Verify TV audio output settings: On some TVs, you must manually select the Bluetooth device as the audio output after pairing. Go to Sound Output settings and choose your device.
- Check transmitter power: Make sure the transmitter is powered on and not in mute mode.
If you've tried all these steps and still have issues, consult your TV's user manual or the Bluetooth device's documentation. In most cases, a simple reset or re-pairing solves the problem.
