10 Best Bluetooth Audio Transmitters 2026 in the United States

The AirFly Pro 2 is a versatile Bluetooth 5.3 adapter that can turn any device with a 3.5mm headphone jack into a wireless audio source or receiver, making it ideal for travelers, gym-goers, and anyone wanting to cut the cord. It supports aptX HD Adaptive, delivering clear, rich sound with low latency—ensuring movies and games stay in sync without annoying delays. One standout feature is its ability to pair two sets of headphones simultaneously, perfect for sharing music or movies on flights or road trips.

Battery life is impressive, offering over 25 hours of use on a single charge, which exceeds average durations for similar devices and suits long trips well. The compact and lightweight design makes it easy to carry around, fitting comfortably in a pocket or bag. Compatibility is broad, working smoothly with AirPods, Sony headphones, and most Bluetooth earbuds and speakers. Although it uses a 3.5mm AUX connection and won’t connect directly to devices without a headphone jack unless an adapter is used, Bluetooth 5.3 generally provides reliable connections within typical room or car distances.

The device does not have a display, which simplifies operation but means battery and connection statuses are not visible at a glance. Given these features, the AirFly Pro 2 represents a solid choice for adding wireless audio capability to legacy audio devices with good sound quality, low delay, and long battery life, especially when sharing audio between two listeners is important.

The Twelve South AirFly SE is a compact Bluetooth audio transmitter designed to turn any device with a 3.5mm headphone jack—like airplane entertainment systems, gym equipment, or TVs—into a wireless audio source for your AirPods or other Bluetooth headphones. It supports Bluetooth 5.2 and common audio codecs like aptX and SBC, which helps maintain good audio quality with minimal lag, making it suitable for watching movies or gaming without noticeable delay.

One of its standout features is the impressive battery life, offering over 20 hours of continuous use on a single charge, which is excellent for long trips or extended use. Plus, you can keep it plugged in and charging while using it, so you won’t have to worry about it dying mid-flight. The AirFly SE is very portable, weighing just about 14 grams and small enough to easily carry in a pocket or bag. It pairs quickly and easily with your Bluetooth headphones and provides basic volume control directly on the device, adding to its convenience.

It only supports one audio channel, so it’s focused on personal listening rather than multi-user setups. While it works well with many wireless headphones, it’s mainly designed for compatibility with popular models like AirPods and Bose devices. The latency is low enough for most video content but might not be perfect for highly competitive gaming where every millisecond counts. This adapter is an excellent choice for travelers or anyone wanting to cut wires and enjoy wireless audio from older or non-Bluetooth devices, combining solid sound quality, long battery life, and easy portability.

The Twelve South AirFly SE is a handy Bluetooth audio transmitter designed to make wired devices wireless by connecting them to your AirPods, wireless earbuds, or headphones. It works with any device that has a 3.5mm audio jack, which means you can use it on airplanes, gym machines, tablets, or gaming gear. One of its strongest points is the long battery life, offering more than 20 hours of continuous use, which is great for long trips or extended sessions without worrying about recharging. The device is small and light, making it easy to carry around. Pairing is simple and quick, so you can start listening almost immediately. It also has built-in volume controls, giving you convenient control without needing your connected device.

This product is mainly optimized for AirPods and similar earbuds, supporting most wireless headphones. If you want a transmitter with advanced audio codecs for the best sound or very low latency, this might not be the perfect fit. For travelers and casual users seeking to cut the cord and enjoy wireless audio easily from old devices with headphone jacks, the AirFly SE offers a reliable, user-friendly solution.
