Customers find the Bluetooth adapter works well with Apple AirPods Pro and is essential for air travel, particularly for roundtrip international flights. The device is easy to set up and use, with well-written instructions, and one customer reports it worked without interruption for a 5-hour flight. Sound quality and battery life receive mixed reviews - while some say the sound is better and the battery life is good, others report low volume with AirPods and the device running out of charge within 2 hours. Connection ease and audio latency are also mixed aspects, with some customers reporting easy pairing with wireless earbuds and low latency, while others experience connection issues and a noticeable delay in audio transmission.

I bought this product to use for my 16 hours long overseas flight. After a brief research, I found this product to work well with Apple AirPods Pro, and my experience with it agrees.

Pros:
- It paired with AirPods Pro quickly.
- It stayed connected throughout my flight with some small hiccups but restarting it solved the problem.
- The battery stayed charged throughout the flight.
- It's a light and pocketable device that comes with a small pouch.
- It seems to be sturdy as I dropped it a few times, and it still works without any issues.

Cons:
- It is expensive compared to the competitors.
- Using it with the PC, when the speaker sound is quiet or silent, it tends to shut itself off, but it turns back on again within a second. It's kind of annoying, but I got used to it.
- It transmits a decent quality sound, but don't expect an audiophile quality sound.
- When I put my AirPods in the case to charge for 10 minutes, then put it back in my ear again, it couldn't connect right away. Restarting the device solved the problem.

Overall, it is a good product to use with AirPods during travels.

Works well, good battery life
Reviewed in the United States on April 8, 2022

Overall this device works well. I have had it for a week now, I charged it up completely then started using it with my regular use case - listening to a pocket radio when I walk my dog in the morning.
I paired it up with my Galaxy Buds+ and the pairing was easy. Worked the first time I tried.

Have now used it for 5 days straight on a fully charged unit - 2-3 hours per day. Still on the single charge.

Every morning I put in my earbuds in, turn on the device, then turn on the radio. The Buds+ connect every time, and by the time I turn on the radio everything is working properly and I am listening to my favorite morning show.

Have not tried pairing a second set of earbuds but likely will this weekend.

Range is adequate (since I keep it in my pocket). Stays connected when I go across the house about half way, then it starts to get a little "warbly", but that is to be expected. I will try it on a plane in a couple of weeks and if there are any issues I will update but I suspect that for listening to the movies audio and music will work well.

Concerns - The connection of the device at the base of the unit and also the the plug, the unit is a bit wobbly and I wonder how long before the connection is broken. Easy to forget on a plane, I have left a Kindle Paperwhite in the seat pocket on a trip, I can see me leaving this plugged in to the seat back when deplaning. Battery recharge life - how long will it hold a good charge like it does now.

I recommend this device, even at the price point. It delivers on connectivity, battery life, ease of use.

I've found the AirFly to be easy to connect to and it does exactly what it's supposed to do - transmit sound to my bluetooth earbuds. I've used it for a couple hours daily for a few months and it works great. However, after a couple months, the on/off switch stopped functioning, making it impossible to turn off. I contacted Twelve South and, with just a couple simple steps, they quickly sent out a replacement unit. Great customer service.

Toller kabelloser Sender für unterwegs - pefekt für Apple!

Das Einrichten des Airfly-Duos war sehr unkompliziert. Das Gerät konnte in kürzester Zeit in Betrieb genommen werden und konnte problemlos mit meinen Bluetooth-Kopfhörern verbunden werden. Eine stabile Verbindung ohne Aussetzer oder Verzögerungen gewährleistet ein ausgezeichnetes Hörerlebnis.

Ein wesentlicher Vorteil ist die Dual-Mode-Funktion. Das Airfly Duo lässt sich als Sender und Empfänger nutzen. Das heißt, dass ich ihn nicht nur für drahtlose Kopfhörer verwenden kann, sondern auch für die Verbindung meines Tablets oder meines Smartphones mit drahtlosen Lautsprechern. Die Vielseitigkeit des Airfly Duo ist erstaunlich nützlich, was es zu einem echten Allrounder macht.

Die Dauer der Akkulaufzeit ist erstaunlich. Der Akku hält auch bei längeren Reisen zuverlässig. Das Laden über USB-C ist schnell und unkompliziert. Ein weiterer Vorteil ist die kompakte Größe des Geräts, das leicht in jede Tasche passt und unterwegs wenig Platz einnimmt.

Der Airfly Duo bietet einen klaren und qualitativ hochwertigen Klang. Es war mir nicht möglich, einen Unterschied zur kabelgebundenen Verbindung zu erkennen. Das ist wirklich erstaunlich. Ich genieße die Freiheit, mich ohne Kabelsalat zu bewegen, insbesondere wenn ich Filme und Musik sehe.

Alles in allem freue ich mich sehr über das Airfly Duo kabellose Sender. Er ist unkompliziert zu handhaben, hat vielfältige Anwendungsmöglichkeiten und bietet eine ausgezeichnete Klangqualität. Eine eindeutige Empfehlung für jeden, der seine Geräte kabellos anschließen und flexibel unterwegs sein will.
