Pros
- Effortless plug-and-play setup that consistently works as advertised, even with older Bluetooth headphones
- Dual-link capability allows two listeners to share one audio source, a rare and highly practical feature for travel
- Exceptional 25-hour battery life handles long-haul flights with power to spare
- Low or no perceptible audio latency reported by multiple users, keeping video and audio in sync
- Compact and lightweight design makes it easy to pack and carry without adding bulk to your travel bag
Cons
- Functions as a transmitter only with no microphone support, making it unsuitable for phone calls or voice applications
- aptX Adaptive audio quality benefits are only realized with compatible headphones, so users with basic Bluetooth earbuds may not notice the premium codec advantage
- No built-in receiver mode means it cannot be used to stream audio to a wired speaker or older audio equipment
The Avantree Relay is a compact Bluetooth transmitter built specifically for travelers who want to use their wireless headphones with airplane entertainment systems. It plugs into any standard 3.5mm audio jack and broadcasts audio to up to two pairs of Bluetooth headphones at once, making it an outstanding solution for couples or travel partners flying together.
Where the Relay truly stands out is its use of Qualcomm aptX Adaptive and aptX HD technology, which delivers noticeably clearer, more detailed audio compared to standard Bluetooth transmitters. Real-world users consistently report zero perceptible latency and clean sound with no static, even when paired with older Bluetooth headphones that lack the latest codecs.
Battery life is one of the Relay's strongest selling points. The 25-hour playtime on a single charge comfortably outlasts even the longest transoceanic flights, and the onboard LED battery indicator takes the guesswork out of knowing when to recharge. The included dual-prong airplane adapter and a straightforward 3-step pairing process mean you spend less time fiddling with settings and more time enjoying your content.
On the downside, the Relay is strictly a transmitter. It has no microphone and cannot be used for phone calls, voice assistants, or receiving audio from another Bluetooth device. Users who expect it to double as a hands-free device or a Bluetooth receiver will be disappointed, so it is important to verify your use case before purchasing.
Overall, the Avantree Relay earns its place as a top-ranked Bluetooth transmitter for travelers. It is reliable, easy to use, and genuinely improves the in-flight experience for anyone committed to wireless audio. Backed by a solid warranty and responsive customer support, it represents excellent value for frequent flyers and occasional travelers alike.
The Avantree Relay is purpose-built for air travelers who prefer Bluetooth headphones or earbuds over the wired options typically provided on flights. If you rely on noise-canceling headphones for long journeys, this device eliminates the need for awkward wired adapters and lets you move freely in your seat.
It is especially valuable for couples or travel partners sharing a row, since the dual-link feature lets both people connect their own headphones to the same entertainment screen simultaneously. This removes the need to share a single pair of earbuds or purchase two separate adapters.
Beyond aviation, the Relay is also a practical upgrade for anyone with older audio equipment, such as a classic iPod, a non-Bluetooth PC, or a gym treadmill with an AUX output. If your device has a 3.5mm jack but lacks Bluetooth, the Relay can wirelessly bridge the gap to your modern headphones or speakers with minimal setup.

Buying Guide: How to Choose an Airplane Audio Adapter
Bluetooth Version and Audio Codec Support
Newer Bluetooth versions, like 5.0 or 6.0, generally offer improved connection stability, better range, and lower power consumption. This translates to a more reliable link between the adapter and your headphones during a flight. For audio quality, look for support for advanced codecs like aptX Adaptive or aptX HD if your headphones support them.
These codecs can provide higher-fidelity audio with less latency, which is crucial for keeping movie dialogue in sync. A stable connection is paramount when you are miles above the ground, so prioritize adapters with modern Bluetooth technology. Understanding different connection types can also help, as detailed in our resource on 3.5mm headphone adapters.
Battery Life and Charging Method
Consider the total duration of your longest potential travel day, including layovers. An adapter with a battery life exceeding 16 hours should comfortably cover most international journeys. The ability to use the device while it charges via a USB-C cable is a highly valuable feature for ultra-long flights.
This ensures you never run out of power, even on a 14-hour journey followed by a connection. Check if the adapter has a clear battery indicator, so you are never caught off guard. For devices that rely on USB-C for power, you might find our review of the best USB-C headphone adapters useful for other travel scenarios.
Single vs. Dual Connection Capability
<!–Your travel habits should dictate this choice. If you typically fly alone, a single-connection adapter is perfectly sufficient and often more compact. However, if you frequently travel with a partner, friend, or child, an adapter that can connect two pairs of headphones simultaneously is a game-changer.
This allows you both to watch the same movie or show from a single screen without the hassle of a splitter cable. Sharing audio wirelessly makes for a more enjoyable and connected travel experience. This functionality aligns with the broader trend in wireless and streaming audio solutions for convenience.
Form Factor and Additional Features
<!–A compact, lightweight design is ideal for slipping into a carry-on or seatback pocket. Some models include a dual-prong airplane adapter, which is necessary for certain airline seat jacks, while others may require a separate purchase. Built-in volume controls on the adapter itself provide convenient adjustment without needing to fiddle with your headphones.
Consider if you need a transmitter-only device for flights or a 2-in-1 transmitter/receiver that can also work with your car stereo or home speakers. This versatility can make the adapter useful beyond air travel. For a wide range of personal audio gear, visit our main headphones and earbuds category.
