There was a time when every airplane seat had a headphone jack and every passenger had a tangled pair of cheap earbuds. Today, most of us carry excellent Bluetooth headphones, but the seat-back entertainment system still expects us to plug something in. It’s an annoying little problem that has spawned an entire category of travel gadgets.
British audio company iFi thinks it can do better with the UP Travel Max, a $129 Bluetooth transmitter and receiver that promises CD-quality wireless audio in a package smaller than a USB stick.
The interesting part isn’t just that it works on airplanes. It’s that it can bring Bluetooth to practically anything with a 3.5mm audio jack, including that old iPod sitting in your drawer.
A Little Adapter That Does Both Jobs
The UP Travel Max is essentially two devices in one. In transmit mode, it takes audio from a wired source and sends it to Bluetooth headphones. Plug it into an airplane entertainment system, for example, and you can watch a movie using your own wireless headphones instead of the airline’s terrible complimentary pair.
Flip a switch and it becomes a Bluetooth receiver. Plug it into your car’s auxiliary input and you can stream music from your phone to an older stereo that doesn’t support Bluetooth.
This isn’t a new concept, but iFi has made a few interesting design decisions. The 3.5mm connector flips out of the body like an old-fashioned car key, eliminating the need for a dangling adapter cable. The whole thing weighs just 25.7 grams and promises up to 10 hours of battery life.
It’s also an interesting accessory for the growing number of people rediscovering dedicated music players. If you’ve got an old iPod Classic or another MP3 player with a headphone jack, the UP Travel Max can turn it into a Bluetooth music player without modifying the hardware.
That’s arguably more interesting than its airplane functionality. There’s something appealing about carrying an old iPod loaded with thousands of songs while still enjoying modern wireless headphones.
The Audiophile Approach to Bluetooth
Most inexpensive Bluetooth adapters are built around a single chip that handles practically everything. iFi has taken a different approach, pairing a dedicated Qualcomm Bluetooth processor with a Cirrus Logic MasterHIFI digital-to-analog converter.
The company says this arrangement provides better sound quality than conventional all-in-one adapters.
The UP Travel Max supports several Bluetooth codecs, including aptX Lossless, LDAC and aptX Adaptive. The headline feature is aptX Lossless, which can deliver CD-quality audio under suitable conditions when paired with compatible headphones or speakers.
There is a catch, of course. Both ends of the connection need to support the appropriate codec, and the source audio and wireless conditions also matter. Plugging this into an airplane entertainment system won’t magically improve the quality of the movie soundtrack. Likewise, if your headphones don’t support aptX Lossless, you won’t get lossless transmission.
Still, the flexibility is welcome. LDAC provides another high-quality option, while aptX Adaptive offers a low-latency mode intended to keep audio synchronized with video.
A button on the adapter allows users to switch codecs, and holding it down identifies the active codec.
iFi has also included JVCKENWOOD’s K2 Technology, which uses digital processing to reconstruct some of the high-frequency detail and harmonics lost during audio compression. Whether that sounds better will depend on your ears and your source material, but it’s an unusual feature for a travel adapter.
Two Headphones, One Movie
One of the more practical features is support for two pairs of Bluetooth headphones simultaneously.
That means two passengers can watch the same airplane movie without sharing earbuds or carrying a headphone splitter. Anyone who has tried to watch a film with another person on a long flight will appreciate the idea.
The adapter also supports Auracast, the Bluetooth broadcasting technology that allows compatible headphones and speakers to join a shared audio stream. iFi says this can support an unlimited number of listeners, although everyone needs compatible equipment.
Auracast and several other features are managed through iFi’s Nexis smartphone app. The app also handles firmware updates, codec settings, K2 processing and battery optimization.
In receiver mode, the device includes a built-in microphone with Qualcomm noise and echo suppression for hands-free calling. That makes it potentially useful for older cars with auxiliary inputs but no integrated Bluetooth calling system.
Is It Worth $129?
The obvious question is whether a $129 Bluetooth adapter is necessary when inexpensive alternatives already exist.
For someone who just wants to connect wireless headphones to an airplane seat once or twice a year, probably not. Basic transmitters can handle that job for considerably less money.
The UP Travel Max makes more sense for someone who regularly switches between different audio setups. It can connect wireless headphones to an airplane screen, bring Bluetooth streaming to an older car stereo and give an old iPod a new lease on life. It also offers more sophisticated codec support than many basic adapters.
The dedicated DAC, dual-headphone pairing and Auracast support make the package more interesting, although the real-world sound benefits will depend heavily on the devices connected to it.
I particularly like the idea of using it with an old iPod. There is a growing appetite for music players that don’t require notifications, subscriptions or a cellular connection. Adding wireless audio without changing the experience seems like a sensible upgrade.
The iFi UP Travel Max is available beginning October 29, 2026, for $129 in the US, £129 in the UK and €139 in Europe, through iFi Audio.
It’s a fairly expensive solution to a small problem. Then again, if you’ve ever found yourself on a 10-hour flight staring at a headphone jack while holding a perfectly good pair of Bluetooth headphones, you already understand why it exists.
