Editor's Note

This is a recurring post that has been updated with new information.

If you wish you could connect your wireless headphones to watch seatback entertainment on your next flight, the solution is 25% off during Amazon's Black Friday Sale.

While some of the newest aircraft seats offer Bluetooth connectivity in all classes, most airlines don't, and if you have ever endured tinny inflight entertainment audio through cheap airplane-wired headphones — despite traveling with a pair of high-end Bluetooth headphones — we feel your pain. Thankfully, there's a solution.

Forget untangling cords to shove one-size-fits-all pieces of plastic into your ear, only to suffer from thin, baseless sound while watching the latest Hollywood blockbuster.

The Avantree Relay Premium Bluetooth 5.3 Adapter enables you to connect your wireless Bluetooth headphones to any single- or dual-pin 3.5 mm headphone jack with a compact device that fits in your pocket.

Usually $39.99, you can save 25% and pick up this handy gadget from Amazon for just $29.99 right now.

Even if you are traveling in a premium cabin where higher-quality headphones are provided to all passengers, these may not have noise-canceling capabilities, offer the sound quality your personal wireless headphones provide and be as comfortable for a long flight.

If traveling with a friend, the Relay device allows you to connect up to two devices simultaneously, so you could even share screens if you don't mind them leaning in.

With a battery life of up to 20 hours, this nifty device can be used on the world's longest flights. It ensures you can lose yourself in the hours of entertainment your airline provides without sacrificing sound quality or personal comfort.

You can also adjust the headphone sound on the Avantree Relay Premium Bluetooth 5.3 Adapter without hunting for a pop-out aircraft remote control or fiddling with a touchscreen.

If you shop on Amazon, be sure to use a credit card that allows you to earn the most rewards or cash back. Options to consider include:

Bottom line

You never have to suffer through long flights with poor-quality headphones again.

We love the Avantree Relay Premium Bluetooth 5.3 Adapter for its simplicity and ability to connect your favorite wireless headphones to any 3.5-millimeter headphone jack. Now, you can enjoy all the seatback inflight entertainment you wish, and it's 25% off during Amazon's Black Friday Sale.
