10 Best Bluetooth Airplane Adapter

The AirFly Pro 2 is a compact and lightweight Bluetooth adapter designed to bring wireless audio to devices with a 3.5mm headphone jack, making it ideal for use on airplanes, in cars, or with home entertainment systems. It uses the latest Bluetooth 5.3 technology, which helps maintain a stable connection and offers low latency, so audio and video stay in sync – great for watching movies or gaming during travel. The adapter supports aptX HD Adaptive codec, which means sound quality is clear and detailed if your headphones also support this codec.

One standout feature is its ability to pair two sets of Bluetooth headphones simultaneously, perfect for sharing audio with a travel companion without wires getting tangled. Battery life is impressive, providing over 25 hours of use on a single charge, so it can last through long flights or road trips without needing frequent recharging. Controls are straightforward, with quick-access buttons for adjusting volume or muting sound, which adds to its ease of use even when you're on the move. However, the device is powered by a built-in lithium polymer battery, so you will need to remember to charge it before trips. The size is very portable, easily fitting into a pocket or tech pouch, which is convenient for travel.

This adapter is well-suited for travelers who want to upgrade from wired headphones on planes or in cars to wireless freedom, especially if they value good audio quality and the ability to share sound with a friend.

The Avantree Relay is a handy Bluetooth 5.3 adapter designed for travellers who want to use their Bluetooth headphones with airplane entertainment systems or other devices with a 3.5mm audio jack. It supports Qualcomm aptX Adaptive codec, which helps deliver good sound quality with minimal delay—great for watching movies or listening to music on flights. One of its strong points is the ability to connect two Bluetooth headphones at once, so you can share audio with a travel companion, though this might not be perfectly stable with every headphone model.

The adapter offers an impressive 20 hours of battery life, which should easily cover long-haul flights without needing a recharge. Its size and weight make it portable enough to carry comfortably, fitting well into travel kits. Controls are simple and intuitive, with LED indicators for battery and pairing status, making it user-friendly even if you’re not tech-savvy.

It’s important to note that it’s not compatible with smartphones, speakers, or car stereos, limiting its use to devices with a 3.5mm output like airplane screens or gym machines. Also, while it supports popular headphones including AirPods, Sony, Bose, and Beats, pairing performance can vary depending on the headset. If you’re looking for a travel-focused Bluetooth transmitter that prioritises ease of use, good battery life, and the option to share audio, the Avantree Relay fits well, but be mindful of its compatibility limits outside of audio jacks and certain headphone models.

The UGREEN Bluetooth 5.2 Transmitter Receiver is a solid choice for anyone looking for a versatile Bluetooth adapter suitable for airplanes and more. It uses the latest Bluetooth 5.2 technology, which offers a stable connection and supports dual pairing, allowing you to connect two devices at once and switch between them easily. This is handy if you want to manage calls and music from different devices without hassle. Battery life is impressive, with up to 28 hours on transmit mode and 20 hours when receiving audio, plus a quick 2-hour charge via USB-C, so it’s reliable for long trips. The device supports a 10-meter wireless range, which should be plenty for airplane seats or room-sized spaces.

It’s very compact and lightweight, weighing under 20 grams, making it easy to carry around without adding bulk. It connects through a standard 3.5mm jack, which means it works with most headphones, speakers, and car systems. However, there is no explicit mention of advanced audio codec support like aptX or AAC, so audiophiles might not get the best sound quality possible. The plastic build is lightweight but might not feel as sturdy as metal alternatives. Also, while it’s designed to be user-friendly, beginners may need a moment to understand switching between transmit and receive modes.

This adapter serves as a great everyday companion for travelers and casual users who want flexible Bluetooth connectivity for various devices, especially when using wired headphones or speakers without built-in Bluetooth.
