If you have ever tried connecting AirPods or wireless headphones to an airplane entertainment system, an older TV, a treadmill, or a car stereo with only a 3.5mm jack, you probably know the problem.
Your headphones are wireless, but the device you want to use still expects a cable.
That is exactly where the Twelve South AirFly Pro 2 becomes interesting.
This compact Bluetooth adapter is designed to turn a traditional 3.5mm audio connection into a wireless Bluetooth connection. It can also work in the opposite direction as a Bluetooth receiver.
But is it actually worth carrying another gadget?
And does the ability to connect two pairs of wireless headphones make it more useful than a basic Bluetooth adapter?
Let’s take a closer look.
Twelve South AirFly Pro 2 Review
The Twelve South AirFly Pro 2 is a Bluetooth 5.3 transmitter and receiver designed for devices that use a 3.5mm AUX connection.
Key highlights:
- Bluetooth 5.3 connectivity
- Supports two Bluetooth headphones simultaneously
- Transmitter and receiver modes
- Supports AirPods, Beats, Sony and other compatible Bluetooth headphones
- aptX HD Adaptive support
- More than 25 hours of claimed battery life
- Compact, travel-friendly design
- Useful with airplanes, TVs, treadmills, cars, boats and other AUX-equipped devices
The biggest reason to consider it is simple: it lets you use wireless headphones with devices that don’t have built-in Bluetooth.
What Is the Twelve South AirFly Pro 2?
The AirFly Pro 2 is essentially a bridge between traditional wired audio connections and modern wireless headphones.
In transmitter mode, you connect the adapter to a device with a compatible 3.5mm audio connection.
The AirFly Pro 2 then sends that audio wirelessly to Bluetooth headphones or earbuds.
For example, you could connect it to an airplane entertainment system and listen through compatible AirPods or wireless headphones.
But that’s only half of the story.
The AirFly Pro 2 can also operate as a Bluetooth receiver.
In receiver mode, you can send audio from a compatible smartphone or other Bluetooth device to an AUX-equipped stereo.
That makes it more versatile than a simple airplane Bluetooth transmitter.
Why Is the AirFly Pro 2 Useful?
Bluetooth headphones are now extremely common.
The problem is that many older or specialized devices still don’t have Bluetooth.
Think about:
- Airplane entertainment systems
- Gym treadmills
- Older TVs
- Gaming consoles
- Car stereos with AUX
- Boat audio systems
- Older speakers and stereo equipment
Replacing the entire audio system just to get Bluetooth isn’t always practical.
A small Bluetooth adapter can solve that compatibility problem.
That’s the main idea behind the AirFly Pro 2.

AirFly Pro 2 Features
1. Bluetooth 5.3
The AirFly Pro 2 uses Bluetooth 5.3, giving it a modern wireless connection for compatible Bluetooth audio devices.
For most buyers, the important point isn’t the Bluetooth version number itself.
What matters is that the adapter is designed to work with modern wireless headphones and earbuds.
The supplied specifications also list aptX HD Adaptive support.
Keep in mind that the actual codec used can depend on the connected headphones and source device, so this shouldn’t be treated as a guarantee of a particular audio experience with every setup.
2. Connect Two Bluetooth Headphones
This is one of the most useful features of the AirFly Pro 2.
It supports dual pairing, allowing two compatible sets of Bluetooth headphones to connect at the same time.
Imagine you’re sitting next to someone on a long flight and want to watch the same movie.
Instead of sharing one pair of earbuds or dealing with a wired splitter, both people can use their own wireless headphones.
This can also be useful when sharing music, videos or other audio in compatible situations.
For couples and frequent travelers, this feature alone may make the AirFly Pro 2 more appealing than a basic Bluetooth transmitter.
3. Transmitter and Receiver Modes
Another major advantage is that the AirFly Pro 2 isn’t limited to transmitting audio.
It can work in two different ways.
Transmitter mode:
Sends audio from a compatible 3.5mm source to Bluetooth headphones.
Receiver mode:
Receives Bluetooth audio from a compatible phone or other device and sends it through an AUX connection to compatible audio equipment.
This two-way functionality gives the adapter more long-term usefulness.
Instead of buying one adapter for your airplane and another for your car, you can potentially use the same device for both purposes.
4. More Than 25 Hours of Battery Life
Battery life is particularly important for a travel accessory.
According to the supplied product information, the AirFly Pro 2 offers more than 25 hours of battery life.
That’s useful for long flights, road trips and extended listening sessions.
Of course, real-world battery life can vary depending on usage and operating conditions.
The adapter also skips an unnecessary display, keeping the device relatively simple.
For a small accessory that mainly needs to connect and transmit audio, that simplicity makes sense.
5. Compact Design
One of the biggest advantages of a travel gadget is being small enough that you don’t mind carrying it.
The AirFly Pro 2 is designed to fit easily into a tech pouch, carry-on bag or pocket.
Its compact size makes it easier to keep with your headphones or travel accessories.
That’s important because an accessory that stays at home isn’t much help when you’re sitting in an airport.

AirFly Pro 2 for Airplane Travel
This is probably the most obvious use case.
Many airplane entertainment systems provide a traditional headphone connection rather than built-in Bluetooth.
If you prefer AirPods or other wireless headphones, the AirFly Pro 2 can act as a Bluetooth transmitter.
You connect the adapter to the available audio connection and pair your headphones.
The dual-pairing feature is especially interesting for couples traveling together.
Both people can potentially listen to the same entertainment using their own compatible wireless headphones.
One thing to remember
Airplane entertainment systems and headphone connections can vary.
It’s a good idea to check the aircraft and entertainment setup before relying on any Bluetooth adapter as your only listening option.
AirFly Pro 2 for the Gym
Gym equipment is another situation where a Bluetooth adapter can be useful.
Some treadmills and other equipment still provide a wired headphone connection.
If you prefer wireless earbuds, the AirFly Pro 2 can provide a way to bridge the connection.
For people who regularly watch gym TVs while exercising, this can be a convenient solution.
AirFly Pro 2 for Your Car
Here’s where the receiver mode becomes particularly interesting.
Many older vehicles have an AUX input but don’t offer convenient Bluetooth audio streaming.
If your car has a compatible AUX connection, the AirFly Pro 2 can receive Bluetooth audio from your phone and send it through the car’s audio system.
That means you may be able to modernize an older audio setup without replacing the entire stereo.
For someone with an older car and a perfectly good sound system, this could be a practical solution.
AirFly Pro 2 for Older Home Audio Equipment
The same idea can work at home.
If you have an older stereo, speaker system or other compatible audio equipment with an AUX input, the AirFly Pro 2 can provide a way to receive audio wirelessly from a compatible Bluetooth device.
This can be useful if your existing equipment still sounds good but lacks modern wireless connectivity.
Instead of replacing working equipment, an adapter can sometimes fill the technology gap.

AirFly Pro 2 vs a Basic Bluetooth Adapter
You might be wondering why you should buy the AirFly Pro 2 instead of a cheaper Bluetooth transmitter.
The answer depends on how you plan to use it.
A basic Bluetooth transmitter can be perfectly adequate if you only need to connect one pair of wireless headphones to one audio source.
The AirFly Pro 2 offers additional flexibility.
| Feature | AirFly Pro 2 | Basic Bluetooth Adapter |
|---|---|---|
| Bluetooth transmission | Yes | Usually |
| Bluetooth receiving | Yes | Depends on model |
| Two headphone pairing | Yes | Not always |
| Bluetooth 5.3 | Yes | Depends on model |
| Travel-friendly design | Yes | Varies |
| Best for | Flexible, multi-purpose use | Simple setups |
The important question isn’t simply whether the AirFly Pro 2 is better.
It’s whether you will actually use the additional features.
Who Should Buy the AirFly Pro 2?
The AirFly Pro 2 makes the most sense for people who regularly encounter older audio connections.
You should consider it if:
- You travel frequently.
- You use AirPods or wireless headphones.
- You often use airplane entertainment systems.
- You want to connect two pairs of wireless headphones.
- You use gym equipment with a headphone jack.
- Your car has AUX but doesn’t have convenient Bluetooth audio.
- You own older audio equipment.
- You want one device that can transmit and receive Bluetooth audio.
For these users, the extra functionality can make the adapter considerably more useful than a basic transmitter.
Who Probably Doesn’t Need It?
Not everyone needs a Bluetooth adapter.
If your phone, laptop, television, car and other devices already have Bluetooth built in, you may have very little reason to buy one.
It’s also worth remembering that the AirFly Pro 2 is not intended to replace a complete audio system.
Its purpose is much simpler:
Connect modern Bluetooth audio devices to equipment that still relies on a traditional audio connection.
If you don’t regularly encounter that situation, the money may be better spent elsewhere.
Things to Consider Before Buying
1. Check Your Device’s Audio Connection
The AirFly Pro 2 is designed around AUX/3.5mm audio connectivity.
Before buying, check the device you want to connect.
This is particularly important with newer electronics that may use different connection types.
2. Think About Dual Pairing
Ask yourself whether you’ll actually use the ability to connect two headphones.
If you usually listen alone, it may not be a major benefit.
If you frequently travel with a partner or share entertainment, however, it can be one of the most useful features.
3. Check Compatibility
Bluetooth is widely supported, but individual devices can behave differently.
If you are buying the AirFly Pro 2 specifically for a particular pair of headphones, TV, car or entertainment system, check compatibility before purchasing.
4. Remember That It Needs Charging
The claimed battery life of more than 25 hours is useful, but it’s still a rechargeable device.
If you’re taking it on a long trip, remember to charge it beforehand.
A small adapter isn’t very useful if its battery is empty when you need it.
Is the AirFly Pro 2 Worth It?
This is probably the biggest question.
The answer depends heavily on your use case.
If you regularly travel, use airplane entertainment systems, own older AUX equipment or share audio with another person, the AirFly Pro 2 has a compelling feature set.
The combination of:
- Bluetooth 5.3
- Dual headphone pairing
- Transmitter mode
- Receiver mode
- More than 25 hours of claimed battery life
- Compact design
makes it a versatile travel and audio accessory.
On the other hand, if virtually every device you use already supports Bluetooth, you may not get enough benefit from carrying another gadget.

Final Verdict
The Twelve South AirFly Pro 2 solves a relatively simple problem, but it solves that problem in several useful situations.
Its biggest advantage isn’t simply Bluetooth connectivity.
The real benefit is being able to bring your wireless headphones into situations where a traditional 3.5mm audio connection would normally require a cable.
The ability to connect two Bluetooth headphones simultaneously makes it particularly interesting for couples and people who frequently share entertainment.
The receiver mode is another useful addition, especially for older AUX-equipped cars and audio systems.
The more than 25-hour claimed battery life and compact design also make sense for a travel accessory.
However, it’s not a must-have for everyone.
If you rarely encounter a headphone jack, you probably won’t get much value from it.

- Travel regularly
- Use wireless headphones
- Want to connect two headphones at once
- Have older AUX-equipped audio equipment
- Want a compact transmitter and receiver in one device
