You can bridge AUX and Bluetooth with a small adapter. The right choice depends on the direction of the audio.

1. To send audio from an AUX jack (like a TV’s headphone out) to Bluetooth headphones or speakers, use a Bluetooth transmitter.
2. To receive audio from a phone and play it through an AUX input (like a car or home stereo), use a Bluetooth receiver.
3. Plug the adapter into the 3.5 mm or RCA port, power it via battery or USB, and put it in pairing mode.
4. Pair your Bluetooth device and start at a moderate volume.

Results can vary by setup, but these adapters available at Walmart can make wired gear wireless.

A Bluetooth AUX adapter is a compact device that connects older audio gear to wireless audio.

• Receiver mode: It takes Bluetooth audio from your phone and feeds it into an AUX/RCA input on a car or stereo.
• Transmitter mode: It sends audio from an AUX/optical output (like a TV) to Bluetooth headphones or speakers.
• Most are powered by USB or an internal battery and pair like standard Bluetooth devices.
• Some models include features such as hands‑free calling or dual connections.

Range, latency, and audio quality depend on the environment and devices. You’ll find a variety of adapter types on Walmart.com and in stores.

If your TV doesn’t have built‑in Bluetooth, a Bluetooth transmitter can help.

1. Identify your TV’s audio output: 3.5 mm headphone jack, RCA, optical, or coaxial.
2. Choose a transmitter that supports the available port(s), then connect and power it (USB or wall power).
3. Set the TV’s audio format to stereo/PCM if needed.
4. Put the transmitter in pairing mode and pair your Bluetooth headphones or speaker.
5. Adjust TV and device volume gradually to avoid distortion.

For smoother lip‑sync, look for adapters that support low‑latency Bluetooth modes. Availability and performance can vary by TV, room, and connected devices. Shop a range of options at Walmart.

Adding Bluetooth to a car without it is usually straightforward.

1. If your car has a 3.5 mm AUX input, plug in a Bluetooth receiver, power it (USB/car charger), and pair your phone.
2. If you have a cassette deck, a cassette‑style Bluetooth receiver can route wireless audio through the tape slot.
3. Position any included microphone in a clear spot for hands‑free calling, and keep volume at moderate levels to minimize distortion.
4. Secure cables and adapters so they don’t interfere while driving.

Audio quality and call clarity can vary with vehicle acoustics and road conditions. You’ll find several plug‑and‑play options at Walmart.

Bluetooth adds a bit of delay, but you can often minimize it.

• Use adapters and headphones that support low‑latency Bluetooth modes.
• Connect via optical or direct AUX where possible, and set sources to stereo/PCM.
• Keep devices within line‑of‑sight, reduce wireless interference, and avoid multipoint connections during video.
• Pair only one audio device at a time for the most consistent performance.
• Start with moderate volume on both ends and fine‑tune levels.

Actual results depend on your TV, speakers, and room. For watching movies or gaming, many shoppers choose low‑latency transmitters available at Walmart.
