Frequently Asked Questions
Will the AirFly SE introduce distracting audio lag during focused work sessions?
No, the combination of Bluetooth 5.2 and aptX codec support delivers low-latency audio that is virtually indistinguishable from wired performance for spoken word, music, and ambient focus tracks. Generic Bluetooth transmitters often introduce 200ms+ delays, which the AirFly SE largely eliminates.
Can I leave the AirFly SE plugged into my home office TV or monitor for instant wireless audio?
Yes, this is one of the most popular productivity use cases. The Quick Pairing Mode automatically reconnects to your saved earbuds each time the device powers on, so the audio bridge is ready the moment you start a video call or focus playlist.
Does the 20+ hour battery cover a full work week of intermittent use?
Yes, if you use the AirFly SE for several hours per day at the office, a single charge can easily last an entire work week. For continuous all-day use, the USB-C pass-through charging allows you to power it from a laptop, monitor USB port, or wall adapter without audio interruption.
Is the AirFly SE useful for hybrid workers who split time between home and office?
Absolutely. At less than half an ounce, the AirFly SE slips into a laptop bag or even a pocket, making it easy to move between home and office setups. Once paired, the same earbuds work seamlessly with both work computers, conference room TVs, and home entertainment systems.
Can I use the AirFly SE to take video calls wirelessly through my AirPods on a desktop PC?
The AirFly SE is a transmit-only device, meaning it sends audio from a source to your earbuds but does not relay microphone input back. For one-way listening like webinars, focus music, or conference call audio, it works perfectly, but it cannot replace a headset microphone for two-way calls.
Does the AirFly SE help reduce desktop cable clutter in a home office?
Yes, by replacing long 3.5mm headphone cables with a wireless Bluetooth connection, the AirFly SE removes one of the most common desk tangles. Combined with wireless earbuds, it enables a fully cable-free audio setup that contributes to a cleaner, more focused workspace.
Can the AirFly SE support a 'focus ritual' by reliably playing the same ambient track every session?
Yes, the Quick Pairing Mode ensures your earbuds reconnect instantly each time, so the moment you power on the AirFly SE, your focus playlist or ambient sound app begins playing without manual reconnection. This consistency helps train the brain to enter a focused state faster.
Is the AirFly SE compatible with a home office monitor that has only HDMI audio output?
Most modern monitors do not have a 3.5mm output, but you can connect the AirFly SE to a desktop computer's 3.5mm audio jack, a USB audio adapter, or a separate audio extractor between the monitor and computer. Once connected, it functions identically to any 3.5mm source.
Will the device interrupt my flow state if I need to charge it mid-session?
No, the USB-C pass-through charging is designed specifically for zero audio downtime. You can plug in a power source at any time, and the audio continues playing uninterrupted, so focus sessions are never broken by a charging pause.
Is the AirFly SE loud enough for noisy open-office environments?
The AirFly SE itself does not control volume — output level is determined by the source device and your earbuds. With quality earbuds and a properly level-matched source, the AirFly SE delivers full, undistorted volume that competes well with typical office noise.
How does the AirFly SE compare to a dedicated Bluetooth headphone for productivity?
A dedicated Bluetooth headset is limited to one device and one use case, while the AirFly SE upgrades any existing wired audio source to Bluetooth. For professionals who already own premium earbuds and want to use them across multiple devices, the AirFly SE is the more versatile and cost-effective choice.
Can I use the AirFly SE to wirelessly hear audio from a treadmill desk or under-desk treadmill?
Yes, treadmill desks typically have a 3.5mm headphone jack for the integrated display. The AirFly SE lets you walk and work with wireless earbuds, eliminating cord tangling with the treadmill rails and increasing comfort during long walking sessions.
Is the AirFly SE a good fit for students who study in libraries or shared spaces?
Yes, students can plug the AirFly SE into library computers, study room TVs, or shared media consoles to use their own wireless earbuds for silent listening. It is far more reliable than cheap dongles, which is critical for maintaining focus during long study blocks.
I am worried about Bluetooth interference in a crowded office — does it handle multiple devices nearby?
Bluetooth 5.2 is significantly better at managing interference than older versions, with adaptive frequency hopping that avoids congested channels. In real-world office environments with many wireless devices, the AirFly SE maintains a stable connection far better than generic 4.2-era transmitters.
Is the AirFly SE better than AirPods alone for a productive home office setup?
AirPods alone cannot connect to 3.5mm outputs like older monitors, treadmill consoles, or in-flight entertainment. The AirFly SE bridges that gap, making AirPods truly universal across your entire work and travel ecosystem, which is the core productivity benefit.
How does this compare to buying a second pair of AirPods dedicated to office use?
A second pair of AirPods is far more expensive and does not solve the connection problem with non-Bluetooth sources. The AirFly SE lets a single pair of premium earbuds work across all devices, which is more economical and reduces the hassle of switching earbuds between contexts.
How do I set up the Twelve South AirFly SE for the first time?
Plug the AirFly SE into the 3.5mm headphone jack of your audio source, slide the power switch on, and the device enters pairing mode automatically the first time. Open the Bluetooth settings on your earbuds, select 'AirFly SE' from the list, and pairing is complete. Subsequent uses only require powering on the device, which uses Quick Pairing Mode to reconnect automatically.
Can the AirFly SE connect to two pairs of earbuds at the same time?
The AirFly SE standard model pairs with one set of earbuds at a time. For dual-listener setups, Twelve South offers the AirFly Pro and AirFly Duo models that support two simultaneous connections. If two-person listening is a priority, consider upgrading to one of those variants.
How do I reset the AirFly SE if it stops pairing correctly?
To reset, hold the pairing button for approximately 5-10 seconds until the LED indicator flashes rapidly in an alternating pattern. This clears all previously paired devices and returns the AirFly SE to factory pairing mode, allowing a fresh connection to be established.
Does the AirFly SE work with AirPods Pro and AirPods Pro 2?
Yes, the AirFly SE works with all generations of AirPods, including AirPods Pro, AirPods Pro 2, AirPods Max, and standard AirPods. It uses standard Bluetooth 5.2 protocols, so any Apple earbuds that pair over Bluetooth will work without additional configuration.
Will the AirFly SE work with Android earbuds like Samsung Galaxy Buds or Google Pixel Buds?
Yes, the AirFly SE is universal and works with any Bluetooth 5.2-compatible earbuds, including Samsung Galaxy Buds, Google Pixel Buds, Sony WF series, Bose QuietComfort Earbuds, and more. It is not limited to Apple products, though it is optimized for use cases that complement the Apple ecosystem.
What is included in the box when I purchase the AirFly SE?
The box contains the AirFly SE Bluetooth transmitter, a USB-C charging cable, a 3.5mm audio cable for sources with separate aux output, and a quick-start guide. Earbuds, headphones, and wall adapters are not included and must be purchased separately if you do not already own them.
Is the AirFly SE safe to leave plugged in and charging overnight?
Yes, the AirFly SE uses a standard lithium-polymer battery with built-in overcharge protection. The device can be left connected to a power source indefinitely without damaging the battery, and the pass-through charging feature is specifically designed for continuous operation.
Can the AirFly SE be used on airplanes during takeoff and landing?
Bluetooth transmitters are typically classified as small portable electronics, which most airlines permit during all phases of flight, including takeoff and landing. The AirFly SE does not transmit radio signals at high power, but you should always follow your specific airline's crew instructions regarding electronic device use.
What is the difference between a Bluetooth transmitter and a Bluetooth receiver?
A Bluetooth transmitter sends audio from a non-Bluetooth source (like an airplane screen or treadmill) to wireless earbuds, which is exactly what the AirFly SE does. A Bluetooth receiver does the opposite: it receives Bluetooth audio and outputs it through wired speakers or headphones. The AirFly SE is a transmitter, designed to make wired audio sources wireless.
