If you want a compact Bluetooth transmitter for streaming audio from an airplane’s 3.5 mm jack to your wireless headphones, choose Avantree Voyager Airplane; if you need a large, organized backpack for carrying a laptop and travel gear, choose Bxiuna Travel Backpack. They solve different travel problems, so my choice comes down to whether you need wireless audio or somewhere to carry your things.
• Avantree Voyager Airplane’s biggest strength: It sends audio from a 3.5 mm AUX source to Bluetooth headphones, with an OLED display for connection and battery information. Trade-off: Classic Bluetooth connects to one headset, and it is not a backpack or a standalone audio player.
• Bxiuna Travel Backpack’s biggest strength: Its 37-liter storage, six compartments, and padded laptop sleeve make it a capable carry-all for work and travel. Trade-off: It organizes and carries gear; it does not transmit audio to wireless headphones.
• Choose Avantree if your main need is listening wirelessly to an airplane entertainment system or another AUX source.
• Choose Bxiuna if your main need is carrying a laptop, clothing, and travel accessories in one backpack.
Avantree Voyager Airplane: Who It's For
The Avantree Voyager Airplane is a Bluetooth audio transmitter, not a headset. Connect it to an airplane entertainment system, gym equipment, or another audio source with a 3.5 mm AUX output, then pair it with Bluetooth headphones or earbuds. That makes it a focused travel accessory for someone who wants to keep using their wireless headphones with a wired audio jack.
Auracast support offers another path for sharing audio, but it requires compatible earbuds, headphones, or receivers. In Classic Bluetooth mode, the transmitter connects to one headset, not two. The stated compatibility is for Bluetooth headphones and earbuds; it is not intended for phones, tablets, hearing aids, or TVs without a 3.5 mm AUX output.
Who should skip it: Skip Avantree if you want a backpack, need a transmitter that pairs with two ordinary Bluetooth headsets at once, or want to connect a device without a compatible AUX output.
The Bxiuna Travel Backpack is designed for carrying gear rather than handling audio. It has 37 liters of storage, six compartments, and two main zippered pockets. A padded sleeve is described as fitting laptops up to 17.3 inches, while two ventilated mesh pockets and additional internal compartments help separate accessories and smaller items. For a commute or work trip, that layout can keep a laptop and everyday items from becoming one jumble in the main compartment.
Travel-focused details include a trolley sleeve for attaching the bag to luggage and a discreet pocket on the back panel for essentials. The backpack also has adjustable, breathable shoulder straps and honeycomb-style back padding. Those features are aimed at making a loaded bag more manageable to carry; they are not a substitute for checking whether its capacity and shape suit your particular packing routine. The listed dimensions are 18.3 by 13 by 11 inches, and the product information also lists dimensions of 7 by 13 by 18.8 inches, so confirm the measurements against your own travel needs.

Who should skip it: Skip Bxiuna if your priority is converting airplane AUX audio for Bluetooth headphones, or if you do not need a large backpack with a laptop sleeve and multiple storage areas.
• Best for streaming from an airplane’s AUX jack to Bluetooth headphones → Avantree Voyager Airplane. It is built to transmit audio from a 3.5 mm source.
• Best for carrying a laptop and travel gear → Bxiuna Travel Backpack. Its 37-liter capacity, multiple compartments, and padded laptop sleeve are the practical advantages.
• Best for checking pairing and battery status → Avantree Voyager Airplane. Its OLED display shows connection, battery, and audio information.
• Best for attaching a backpack to rolling luggage → Bxiuna Travel Backpack. It has a trolley sleeve for that purpose.
• Best for sharing audio with compatible Auracast devices → Avantree Voyager Airplane. Auracast support depends on compatible headphones, earbuds, or receivers.
• Best for a single Classic Bluetooth headset connection → Avantree Voyager Airplane. It pairs with one headset in Classic Bluetooth mode; that is a limitation if you expect two standard Bluetooth headphones to connect at once.
• Best for separating work and travel items → Bxiuna Travel Backpack. Its six compartments, two main zippered pockets, and mesh pockets give you several ways to organize what you carry.
• Best for a traveler who already owns wireless headphones → Avantree Voyager Airplane. It adds a way to use them with compatible AUX audio sources rather than replacing the headphones.
These products are not direct substitutes. The Avantree is a small audio transmitter for connecting a wired source to wireless headphones; the Bxiuna is a backpack for transporting personal items and a laptop. If you are comparing them because both seem relevant to travel, start with the problem you want to solve. A full backpack will not make airplane audio play through Bluetooth headphones, and an audio adapter will not carry your laptop or charger.
For the Avantree, check the source connection and your headphone compatibility first. The transmitter needs a 3.5 mm AUX output, and Classic Bluetooth mode supports one headset. If you are considering Auracast for group listening, confirm that the receiving headphones or devices support Auracast. If lower latency or higher audio quality matters to you, check whether your headphones support aptX Adaptive or aptX-HD; the adapter alone does not establish that the headphones use those codecs.
For the Bxiuna, think through what you normally pack and how you carry it. Its listed capacity is 37 liters, with a laptop sleeve described for devices up to 17.3 inches. The bag’s water resistance may be useful for everyday travel, but the description does not make it a fully waterproof pack. The built-in headphone jack is a separate convenience from Bluetooth connectivity: it does not turn the bag into an audio adapter.
When deciding what to buy, focus on the feature you will actually use. For the adapter, that may be the AUX connection, display, and compatibility with your headphones. For the backpack, it may be the laptop fit, compartment layout, carry comfort features, and luggage sleeve. If price matters to your decision, check the current price on Amazon rather than relying on an assumed amount; the specifications alone do not tell you which option offers better value for your situation.
My Verdict
In my opinion, I would choose the Avantree Voyager Airplane if my travel priority were streaming airplane entertainment through wireless headphones I already own. Its AUX input, OLED status display, and Bluetooth transmission address that need directly, with the one-headset Classic Bluetooth limit clearly in view.
I would choose the Bxiuna instead if I needed a roomy backpack for a laptop, work items, and travel essentials. The two products serve separate jobs; for streaming audio, my pick is Avantree.
Not in Classic Bluetooth mode: it supports one headset connection. Auracast can be used for audio sharing with compatible headphones, earbuds, or receivers.
It is described as water resistant, not fully waterproof. Its product details do not provide an IPX7 rating, so do not assume the contents are protected from every level of water exposure.
It is described as compatible with Bluetooth headphones and earbuds, but low latency and higher audio quality require headphones that support aptX Adaptive or aptX-HD. Auracast sharing also requires compatible receiving devices.
They serve different travel needs. Avantree handles audio transmission from a compatible AUX source, while Bxiuna carries a laptop and other belongings in a 37-liter backpack with multiple compartments.
