Twelve South AirFly SE Bluetooth Transmitter Review: Enjoy Wireless Audio Anywhere with Your Favorite Headphones

Wireless headphones have become the preferred choice for listening to music, watching movies, and making calls, but many entertainment systems still rely on traditional 3.5 mm headphone jacks. Airplane seat screens, gym equipment, older televisions, gaming devices, and various audio systems often require wired headphones, creating an inconvenience for users who have switched entirely to Bluetooth audio. The Twelve South AirFly SE Bluetooth Transmitter bridges this gap by allowing wireless headphones to connect to virtually any device equipped with a standard 3.5 mm audio output.

Compact, lightweight, and easy to use, the AirFly SE transforms wired audio sources into Bluetooth transmitters, making it possible to enjoy entertainment through AirPods, wireless earbuds, or Bluetooth headphones without carrying extra cables. Designed with travelers and everyday users in mind, it combines long battery life, dependable wireless performance, and effortless setup into a portable accessory that fits comfortably into any travel bag.

Whether you’re flying across the world, working out at the gym, relaxing at home, or using older audio equipment, the AirFly SE makes wireless listening simple and convenient.

Turn Wired Audio into Wireless Freedom

The biggest advantage of the AirFly SE is its ability to convert traditional wired audio outputs into Bluetooth signals.

Simply plug the transmitter into any compatible 3.5 mm headphone jack, pair your wireless headphones, and begin listening without the restrictions of cables.

This functionality opens up wireless listening on a variety of devices, including:

• Airplane entertainment systems
• Televisions
• Treadmills and gym equipment
• Portable gaming devices
• Desktop computers
• Audio receivers
• Older media players

Instead of carrying wired headphones specifically for travel or public equipment, users can continue using their preferred Bluetooth headphones everywhere.

Ideal Companion for Air Travel

Frequent travelers will particularly appreciate what the AirFly SE brings to long flights.

Most airline entertainment systems still require wired headphones, making Bluetooth earbuds difficult to use directly. The AirFly SE solves this limitation by transmitting in-flight audio wirelessly to compatible headphones, allowing passengers to enjoy movies, TV shows, and music more comfortably.

Its compact design takes up very little space, making it easy to store inside a carry-on bag, backpack, or even a jacket pocket.

For travelers who rely on wireless headphones every day, this small accessory can significantly improve the in-flight entertainment experience.

Long Battery Life for Extended Use

Battery performance is one of the strongest features of the AirFly SE.

The transmitter provides more than 20 hours of continuous operation on a single charge, making it suitable for:

• International flights
• Cross-country travel
• Long workdays
• Extended gaming sessions
• Multiple gym visits

Even if the battery eventually runs low, the AirFly can continue operating while connected to power through the included USB-C charging cable.

This pass-through charging capability ensures uninterrupted listening during particularly long sessions.

Reliable Bluetooth 5.2 Connectivity

The AirFly SE uses Bluetooth 5.2, providing stable wireless performance and efficient power management.

Pairing is intentionally simple.

When powered on, the transmitter automatically enters pairing mode, allowing compatible Bluetooth headphones or earbuds to connect quickly without complicated setup procedures.

Once paired, the connection remains dependable across normal listening environments, helping minimize interruptions during music, movies, or gaming.

High-Quality Wireless Audio

In addition to reliable connectivity, the AirFly SE supports aptX and SBC audio codecs.

These codecs help deliver clear and enjoyable sound while maintaining efficient wireless transmission across compatible devices.

Whether watching movies, listening to music, or following spoken dialogue, audio remains natural and well synchronized for everyday entertainment.

The result is a comfortable listening experience that feels much closer to native Bluetooth playback.

Freedom to Move

Unlike traditional wired headphone connections that restrict movement, the AirFly SE offers a wireless operating range of approximately 10 meters (33 feet).

This extended range allows users to move around comfortably without remaining directly beside the connected audio source.

At home, this means greater flexibility while watching television.

At the gym, users can exercise more naturally without worrying about headphone cables.

During travel, the wireless connection also reduces cable clutter inside airplane seats or waiting areas.

Compact Design Built for Travel

Portability is another major strength of the AirFly SE.

Its lightweight construction makes it easy to carry virtually anywhere without adding noticeable weight to luggage or daily carry items.

The minimalist design also keeps operation simple, allowing users to focus on enjoying their content instead of managing complicated settings.

For frequent travelers, commuters, and business professionals, the compact size makes it a practical everyday accessory.

Compatible with a Wide Range of Wireless Headphones

The AirFly SE works with many popular Bluetooth audio devices, including:

• Apple AirPods
• Wireless earbuds
• Over-ear Bluetooth headphones
• On-ear wireless headphones

This broad compatibility allows users to continue using their preferred listening devices rather than purchasing specialized wired alternatives.

Whether you already own premium Bluetooth headphones or compact true wireless earbuds, the AirFly SE helps extend their usefulness across older audio systems.

Simple Everyday Operation

Ease of use is one of the reasons the AirFly SE appeals to such a wide audience.

Using the transmitter requires only a few simple steps:

1. Plug it into a compatible 3.5 mm audio jack.
2. Turn it on.
3. Pair your Bluetooth headphones.
4. Start enjoying wireless audio.

The straightforward setup process makes the device suitable even for users who have little experience with Bluetooth accessories.

 

Final Verdict

The Twelve South AirFly SE Bluetooth Transmitter is a simple yet remarkably practical accessory for anyone who primarily uses wireless headphones. By transforming traditional 3.5 mm audio outputs into Bluetooth connections, it allows users to enjoy modern wireless listening across airplanes, televisions, gym equipment, gaming devices, and countless other audio sources that would otherwise require wired headphones.

Its combination of long battery life, Bluetooth 5.2 connectivity, aptX support, automatic pairing, and lightweight portability makes it especially valuable for travelers and everyday users who appreciate convenience without sacrificing audio quality. The ability to continue operating while charging further enhances its reliability during long flights and extended entertainment sessions.

Overall, the Twelve South AirFly SE delivers an elegant solution to a common problem. Compact, dependable, and exceptionally easy to use, it helps bring wireless freedom to older audio devices while allowing users to enjoy their favorite Bluetooth headphones almost anywhere.
