How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want to turn a living-room TV into a private, two-headphone listening station with zero fuss, choose 1Mii B06TX+; if you need a pocketable travel adapter for airplane seat-back screens and gym machines, choose Avantree Voyager Airplane.
• 1Mii B06TX+ biggest strength: A screen-guided transmitter built for home setups — dual-link audio to two headphones at once, volume buttons on the unit, and four input types (3.5mm AUX, RCA, Optical, Coaxial) so almost any TV or projector connects.
• 1Mii B06TX+ biggest trade-off: It's a transmitter only, it's corded (no battery), and it's not designed for travel or 3.5mm-only sources like airplane jacks — it wants a permanent spot on a table.
• Avantree Voyager Airplane biggest strength: Built for motion — battery powered, 3.5mm AUX and dual-prong airplane inputs, an OLED display that shows your connected device and battery status, plus Bluetooth 5.4 with Auracast support.
• Avantree Voyager Airplane biggest trade-off: Classic Bluetooth is one headphone only (no dual-link), it explicitly is not for TVs without a 3.5mm AUX output, hearing aids, or phones/tablets, and low latency or high-quality audio requires aptX Adaptive or aptX-HD headphones.
• Who each pick is for: 1Mii B06TX+ for the household with a non-Bluetooth TV and one or two pairs of wireless headphones; Avantree Voyager Airplane for the frequent flyer or gym-goer who wants their own earbuds on someone else's screen or machine.
The B06TX+ is a home-first device. Its whole reason for existing is that old TV sitting in your living room: a non-Bluetooth set, a projector, or a desktop PC that you want to feed into wireless headphones without replacing the hardware. It takes AUX 3.5mm, RCA, Optical, or Coaxial in, and sends stereo audio out to Bluetooth headphones or a speaker. That range of inputs is the practical part — you're not hunting for a specific cable type, because the box already covers the ones most TVs and projectors use.
The feature that separates it from a generic dongle is the dual-link mode. Two Bluetooth headphones or speakers can connect at the same time and both play the same audio, which is the difference between one person watching a movie late at night and two people watching it together without waking the house. The built-in screen handles pairing status, which matters if the person setting it up isn't comfortable with blink-pattern pairing rituals — the unit's own description frames it as especially suitable for middle-aged and elderly users, and that's a fair read of the design intent. There's also on-unit volume control, so you're not stuck adjusting from the headphone side every time, and the housing is black ABS measuring roughly 3.9" x 3.4" x 1" at 96.7 g — small enough to sit on a shelf, big enough to have real buttons.
Avantree Voyager Airplane: Who It's For
The Voyager Airplane is the opposite philosophy: a small battery-powered brick you throw in a bag. Plug it into an airplane entertainment system's 3.5mm jack or dual-prong jack, pair your own Bluetooth headphones or earbuds, and you're watching the seat-back screen through your AirPods or Bose instead of the airline's tired wired set. Avantree states it works with all airplane entertainment systems that have a 3.5mm AUX or dual-prong jack, and the same logic carries over to gym equipment and any other 3.5mm AUX source you don't own.
The OLED display is the standout design choice. Instead of guessing whether you're paired, you see the connected device, battery level, and audio status on the screen. Anyone who's spent a flight tapping a blinking light trying to figure out if it's connected will understand why that's worth the space.
It's also forward-looking: Bluetooth 5.4 on a Qualcomm chipset with aptX Adaptive, plus Auracast support for next-generation audio sharing with compatible earbuds and receivers, and firmware upgradeable through Avantree's support page.
Now the honest limitations, and they're significant. In classic Bluetooth mode it supports exactly one headphone — no dual connection, so no watching a movie with a seatmate on one adapter. If you want group listening you have to move to Auracast mode, which requires Auracast-compatible headphones or receivers. Low latency and high audio quality only materialize with headphones that support aptX Adaptive or aptX-HD. And Avantree is blunt about what it isn't for: no hearing aids, no phones, no tablets, no musical instruments, and no TVs without a 3.5mm AUX output. It's also battery powered with a single 1 Wh lithium-polymer cell — great for travel, but a recharge cycle you'll need to plan around, unlike the 1Mii.
Side-by-Side: Which Should You Choose?
• Best for watching TV with two headphones at once → 1Mii B06TX+. Dual-link is core to its design; the Voyager limits classic Bluetooth to one headset.
• Best for the widest range of home inputs → 1Mii B06TX+. AUX, RCA, Optical, and Coaxial versus the Voyager's 3.5mm AUX and dual-prong jacks.
• Best for portability → Avantree Voyager Airplane. Battery powered and clearly built to travel; the 1Mii is corded and designed to stay put.
• Best for people who hate pairing guesswork → both, for different reasons. The 1Mii uses a screen for pairing status; the Voyager uses an OLED showing device, battery, and audio status.
• Best for future-proof audio sharing → Avantree Voyager Airplane. Auracast support and firmware upgradeability point forward; the 1Mii is a stable, single-purpose home tool.
• Best for low-latency movie sync at home → 1Mii B06TX+ with aptX Low Latency headphones. The Voyager needs aptX Adaptive or aptX-HD headphones for its low-latency path.
• Best for elderly or less tech-confident users at home → 1Mii B06TX+. Screen-guided pairing and physical buttons are the whole pitch.
In my opinion, these two barely compete — they solve different problems, and the right pick depends entirely on where the audio source lives. If your problem is a TV at home and you want one or two people listening wirelessly, I'd buy the 1Mii B06TX+: the dual-link mode, four input types, on-unit volume control, and screen pairing make it the more capable home transmitter, and the corded design is a feature there, not a flaw. If your problem is a screen you don't own — a plane seat, a gym treadmill — I'd buy the Avantree Voyager Airplane, because battery power, airplane jacks, and that OLED display are exactly what travel demands. Buy for the room you'll use it in.
The Voyager Airplane, clearly. It's battery powered and accepts dual-prong and 3.5mm AUX jacks, which is what airplane entertainment systems use. The 1Mii is corded and built for home TVs, projectors, and PCs.
In classic Bluetooth mode, no — it supports one Classic Bluetooth headphone. For group listening you'd need to switch to Auracast mode with Auracast-compatible headphones or receivers. The 1Mii B06TX+ is the dual-link option here.
It works with non-Bluetooth TVs, projectors, and computers that offer AUX 3.5mm, RCA, Optical, or Coaxial audio output — 1Mii describes it as compatible with roughly 99% of TVs. It's a transmitter only, so it sends audio out to headphones or speakers, not the other way around.
Both are worth checking on the current price before deciding, since they sit in different use cases rather than competing head-to-head — the page's price button will show you where each lands today. Decide by scenario first: home TV versus travel, then confirm the cost.
