How to choose a Bluetooth headphone transmitter
Choosing the best Bluetooth headphone transmitter depends on how you plan to use it. The first decision is between a transmitter-only device and a combo transmitter/receiver. A transmitter-only model, like our overall pick, is specialized for sending audio from a source like an airplane screen to your headphones. A combo unit adds receiver functionality, letting you stream music from your phone to an old car stereo via an AUX cable, offering more versatility.
For travel, especially flying, check if the adapter includes a dual-prong airplane jack adapter. This small accessory is crucial for connecting to the headphone jacks on many airline seatback systems. Battery life is another key travel consideration; look for models that promise enough playtime to cover a long flight, with some offering 25 hours or more.
What to look for
- Transmitter vs. Transmitter/Receiver: Decide if you only need to send audio to headphones (transmitter) or also want to send audio from a phone to a wired system (receiver).
- Dual Pairing: If you want to share audio with a partner, ensure the model supports connecting two pairs of Bluetooth headphones simultaneously.
- Audio Codecs: For the best possible sound quality with compatible headphones, look for support for advanced codecs like aptX Adaptive or aptX HD.
- Included Adapters: For airplane use, verify the product includes or is compatible with a dual-prong airline adapter.
Finally, consider the user interface. Most transmitters use simple buttons, but some include a small screen that displays the battery level, connection status, and even the audio codec being used. This can be helpful for troubleshooting but may come at the cost of a slightly larger size. For more on different types of audio gear, see our guide on wired vs. wireless headphones.
FAQ
What’s the difference between a Bluetooth transmitter and a receiver?
A Bluetooth transmitter takes an audio signal from a source (like a TV’s headphone jack) and sends it wirelessly to your Bluetooth headphones. A Bluetooth receiver does the opposite: it takes a wireless signal from your phone and outputs it as a wired signal to a speaker or stereo system. Many devices we looked at are 2-in-1 combos, functioning as both a transmitter and a receiver.
Will a Bluetooth transmitter work with any headphones?
Yes, a standard Bluetooth transmitter should work with any Bluetooth headphones or earbuds. However, to use specific high-quality audio codecs like aptX HD or aptX Low Latency, both the transmitter and your headphones must support that same codec. If not, they will default to a basic codec like SBC.
Can I use a Bluetooth transmitter for phone calls?
Most dedicated audio transmitters, like the ones in this roundup, are designed for streaming media audio and do not have a microphone. They are not intended for handling phone calls. The listings for these products typically state they are not for phone call use.
Do I need a special adapter for airplane entertainment systems?
Many airlines use a seatback jack with two metal prongs. To connect a standard 3.5mm plug to it, you need a dual-prong airplane adapter. Some of the transmitters we selected include this adapter, while others do not mention it. Check the product features or specs to see if one is included if you plan to fly often.
