If you want to add wireless audio and aptX support to the Bose QC25 headphones you already own, choose YOCOWOCO aptX; if you need to turn a plane seat's 3.5mm jack into wireless audio for your own Bluetooth headphones, choose Avantree Voyager Airplane. These two gadgets both involve Bluetooth and a headphone jack, but they solve opposite problems. One upgrades a specific pair of wired headphones. The other upgrades a specific audio source. Pick the wrong one and it simply won't do the job you had in mind.

YOCOWOCO aptX vs Avantree Voyager Airplane at a Glance

• YOCOWOCO aptX — biggest strength: a purpose-built module that clips onto the Bose QC25, adds aptX/aptX HD/aptX LL, Bluetooth 5.0, an inline mic and four physical buttons, with around 10 hours of playtime.

• YOCOWOCO aptX — biggest trade-off: it fits the Bose QC25 and nothing else. If you own different headphones, this is the wrong product entirely.

• Avantree Voyager Airplane — biggest strength: an OLED display that shows your connected device, battery level and audio status, plus Bluetooth 5.4, aptX Adaptive and Auracast support for sharing audio.

• Avantree Voyager Airplane — biggest trade-off: it's a transmitter, not a headphone upgrade. Classic Bluetooth handles only one headset at a time, and it won't work with hearing aids, phones, tablets or TVs lacking a 3.5mm AUX output.

• In short: YOCOWOCO is for the person with a QC25 that they love. Avantree is for the person who wants their own earbuds to work on a flight.

YOCOWOCO aptX: Who It's For

This adapter exists for exactly one scenario: you have Bose QuietComfort 25 headphones and you want to cut the cord without buying a new headset. It plugs into the QC25's audio input using a gold-plated 2.5mm connector, and from then on the headphones behave like a modern Bluetooth pair. The aptX support is the headline. It covers aptX, aptX HD for near-lossless music, and aptX LL for audio-video sync — the last one matters if you watch video on a phone or tablet and hate seeing lips move before you hear the words. One important caveat from the spec sheet: aptX only kicks in when the device you pair with also supports aptX. Pair it with a phone that doesn't, and you fall back to standard Bluetooth audio.

The day-to-day design is thoughtfully done. There's a built-in microphone for calls, and four buttons on the adapter handle play/pause, answer and end calls, and volume. Because the module sits tucked against the headphone, it stays out of the way and keeps dust off the controls. Bluetooth 5.0 brings dual-link pairing, so you can keep a phone and a laptop connected at once and switch between them. Battery life is rated at over 10 hours from a roughly two-hour charge, and the adapter can pair with the headphones even while they're powered off — you just slide the QC25's power switch to ON to start listening.

Who should buy it: QC25 owners who want wireless freedom, call handling and physical controls without replacing their headphones. Who should skip it: anyone who doesn't own the QC25, anyone using the QC15 or QC2, and anyone expecting this to work as a general-purpose transmitter for a TV or plane seat. It is a one-headphone device, and it's proud of it.

Avantree Voyager Airplane: Who It's For

The Voyager Airplane attacks a different problem. Airplane seat-back entertainment is usually wired, and your nice wireless earbuds can't touch it. This little transmitter plugs into the seat's 3.5mm AUX or dual-prong jack and broadcasts that audio over Bluetooth to your own headphones. Avantree states it works with all airplane entertainment systems that have a 3.5mm AUX or dual-prong jack, and the same trick applies to gym equipment and other 3.5mm sources. It runs Bluetooth 5.4 on a Qualcomm chipset with aptX Adaptive, and it's firmware-upgradable, so the software isn't frozen at the day you bought it.

The feature that separates it from most airplane adapters is the OLED display. Instead of guessing whether your earbuds actually connected, you see the connected device, the battery level and the audio status right on the screen. That single detail removes a lot of mid-flight fiddling. It also supports Auracast, the newer audio-sharing standard, so with compatible earbuds or receivers (Avantree names Galaxy Buds2 Pro and WF-1000XM5 as examples) you can explore broadcast-style listening. Controls are push-button and touch, and the unit is a black, pocketable transmitter.

Now the honest limitations, because there are several. In classic Bluetooth mode it connects to only one headset — no dual pairing, unlike the YOCOWOCO. Low latency and high audio quality depend on your headphones supporting aptX Adaptive or aptX HD, so basic earbuds won't get the best of it. It is explicitly not compatible with hearing aids, phones, tablets, musical instruments, or TVs without a 3.5mm AUX output — if you use Auracast-enabled hearing aids, Avantree points you to a different model, the Voyager HA. And for group listening you must switch into Auracast mode, which requires Auracast-compatible gear.

Who should buy it: frequent flyers and travelers who want to use their own Bluetooth earbuds or headphones with seat-back screens and other AUX sources, and who value seeing the connection status at a glance. Who should skip it: anyone hoping to upgrade a specific wired headphone, anyone who wants two headsets connected at once in classic Bluetooth, and anyone whose main source is a phone, tablet or TV without a 3.5mm jack.

Side-by-Side: Which Should You Choose?

• Best for upgrading Bose QC25 headphones → YOCOWOCO aptX. It's built for that headphone's connector and arc.

• Best for flights and seat-back entertainment → Avantree Voyager Airplane. It turns any 3.5mm AUX source into a Bluetooth broadcast.

• Best for physical controls and calls → YOCOWOCO aptX. Four buttons plus a built-in mic handle play, calls and volume.

• Best for connection clarity → Avantree Voyager Airplane. The OLED display shows device, battery and audio status.

• Best for pairing two devices at once → YOCOWOCO aptX. Bluetooth 5.0 dual-link keeps two sources connected.

• Best for future-proofing → Avantree Voyager Airplane. Bluetooth 5.4, aptX Adaptive, Auracast and firmware updates.

• Best for long listening sessions on one charge → YOCOWOCO aptX. Around 10 hours of playtime from about a two-hour charge.

• Best for travelers with their own earbuds → Avantree Voyager Airplane. It works with AirPods, Bose and other Bluetooth headphones.

My Verdict

In my opinion, the deciding question is what's broken in your setup. If your headphones are the problem — specifically a Bose QC25 you'd rather not replace — I'd buy the YOCOWOCO aptX, because nothing else here fixes that. If your source is the problem, and you want your own earbuds to work on a plane, I'd buy the Avantree Voyager Airplane, because the OLED display and aptX Adaptive make it the more capable travel tool. They aren't really competitors. They're answers to two different questions, and the wrong answer won't work at all.

FAQ

Is the YOCOWOCO aptX compatible with headphones other than the Bose QC25?

No. It's designed only for the Bose QuietComfort 25. If you have a QC15, YOCOWOCO directs you to a different adapter model entirely, so check your headphone model before buying.

Does the Avantree Voyager Airplane work with two headphones at once?

In classic Bluetooth mode it supports only one headset connection. For group listening you'd switch to Auracast mode, which requires Auracast-compatible headphones or receivers rather than standard Bluetooth earbuds.

Will the Avantree Voyager Airplane work with my TV or phone?

Not by itself. It's built for 3.5mm AUX or dual-prong sources, and Avantree lists phones, tablets, TVs without a 3.5mm output, hearing aids and musical instruments as incompatible. For hearing aids, look at the Voyager HA instead.

Which one should I check the price on first?

Check the current price on Amazon for whichever matches your setup — the QC25 adapter if you own those headphones, the Voyager if you're shopping for travel. They serve different jobs, so price only matters once you've picked the right category.
