How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a dual-link airplane adapter that also doubles as a car and home-audio receiver in one compact white unit, choose Beeitzie Airplane; if you need ultra-low latency for gaming, a second 3.5mm jack, USB-C fast charging and app control, choose Lococo Transmitter Receiver.
• Beeitzie Airplane — biggest strength: Bluetooth 5.4 with aptX Low Latency, a built-in microphone and both AUX and RCA output, so it moves from a plane seat to a car stereo to a home amplifier without extra gear.
• Beeitzie Airplane — biggest trade-off: Dual-link mode drops everyone to SBC audio only, and the brand itself says AirPods and non-aptX headphones can still hear delay — so it is not a latency-first device.
• Lococo Transmitter Receiver — biggest strength: Qualcomm-backed Bluetooth 5.2 with advertised ≤40ms latency, aptX Adaptive/HD, dual 3.5mm jacks and USB-C charging quoted at 90 minutes to full.
• Lococo Transmitter Receiver — biggest trade-off: It is a plastic-bodied black unit with app-based controls, so anyone who dislikes pairing through a phone app will find it more fiddly than a one-button adapter.
• Who each pick is for: Beeitzie for flyers and TV watchers who want one adapter that also feeds a car or stereo; Lococo for gamers, movie marathons and anyone who wants a spare jack plus fast charging.
The Beeitzie Airplane is built around flexibility rather than raw latency numbers. It runs Bluetooth 5.4 and supports aptX Low Latency, and it works in both directions: as a transmitter from a 3.5mm AUX source (a plane's seat-back screen, a TV, a tablet, gym cardio equipment) and as a receiver feeding a car stereo or home audio system through AUX or RCA. That AUX/RCA output combination is the detail that makes it more than a travel gadget — you can realistically leave it plugged into a home amplifier and only carry it on trips when you need it.
Its other practical strengths are a built-in microphone for calls and a quoted 24-hour working time with a 2-hour charge on a 1 Wh lithium-ion cell. It also supports dual link, meaning two sets of headphones can listen at once. If you fly with a partner or want to share a movie on a tablet without splitting a cable, that matters.
Who should buy it: frequent flyers with wired seat-back entertainment, people who want one adapter for plane, TV, gym and car duty, and anyone who prefers a simple white ABS unit with no app required. Who should skip it: gamers chasing the lowest possible lag, and AirPods owners who assume aptX will save them — the brand is explicit that AirPods do not support aptX-LL and that delay can appear with non-aptX headphones. Also skip it if you want it for live music, instruments, karaoke, electronic pianos, guitars needing 2.4G sync, or Bluetooth hearing aids; Beeitzie says outright it is not suitable for those. And remember: in dual-link mode the audio format is locked to SBC only.
The Lococo K1 is the more spec-forward of the two. It pairs Bluetooth 5.2 with Qualcomm technology and advertises ≤40ms ultra-low latency, with adaptive aptX codecs intended to keep audio and video in sync during dialogue and action scenes. That is the headline feature, and it is the reason someone would pick this over a simpler adapter: it is aimed at PS5, Xbox and PC gaming as much as at airplane screens.
Around that core, Lococo adds convenience touches Beeitzie does not list. There are dual 3.5mm jacks and splitter cables for RCA/3.5mm, so hooking up older TVs, stereos and legacy MP3 players is less of a scavenger hunt. Charging is USB-C and quoted at 90 minutes to full, versus the 2-hour charge time on both sheets — a small but real difference mid-trip. The 280mAh battery is rated for 20+ hours. Controls run through an app, with one-touch pairing, memory for two devices, and phone-based volume control.
Who should buy it: gamers who want low latency on a console or PC, couples sharing a movie on a flight with two sets of AirPods, and anyone reviving a turntable, CD player or FM radio into a Bluetooth speaker setup. Who should skip it: people who want zero setup friction and no app, and buyers who specifically need a built-in microphone for hands-free calls — Beeitzie lists one, Lococo's sheet lists noise cancellation for calls rather than a mic feature. Lococo also warns you to pair the device once indoors before flying, so it is not entirely plug-and-go out of the box.
Side-by-Side: Which Should You Choose?
• Best for dual-link audio quality → Beeitzie Airplane's dual link is limited to SBC, so if two-headphone listening is your main use, know that going in.
• Best for charging speed → Lococo Transmitter Receiver, quoted at 90 minutes to full over USB-C versus Beeitzie's 2 hours.
• Best for battery life → Beeitzie Airplane, quoted at 24 hours versus Lococo's 20+ hours.
• Best for car and home audio hookups → Beeitzie Airplane, thanks to AUX plus RCA output in one unit.
• Best for hands-free calls → Beeitzie Airplane, which lists a built-in microphone.
• Best for travel accessories and older gear → Lococo Transmitter Receiver, which includes RCA/3.5mm splitter cables and a storage box.
• Best for simplicity → Beeitzie Airplane; Lococo's control method is an app, which is more capable but more steps.
If I were buying for myself and my main scenario were flights, a TV and a car stereo, I would buy the Beeitzie Airplane. In my opinion the AUX-plus-RCA output, the built-in mic and the quoted 24-hour runtime make it the better all-rounder for everyday listening, and I can live with the SBC limitation in dual-link mode. If gaming lag or fast USB-C charging is the priority, I would switch to the Lococo Transmitter Receiver instead — its quoted ≤40ms latency and aptX Adaptive support are the deciding factors there. Either way, check the current price on Amazon before you commit, since that is not something this comparison covers.
FAQ
Lococo Transmitter Receiver, clearly. Its sheet cites Qualcomm technology and ≤40ms ultra-low latency for PS5, Xbox and PC, while Beeitzie's sheet stresses that non-aptX headphones can experience delay and that it is not for latency-critical audio.
Beeitzie does not list app control — it is a straightforward wired-to-Bluetooth adapter. Lococo lists app as its control method, which adds features like volume control and device memory but also an extra setup step.
Yes, both list an airplane TX mode with 3.5mm AUX input, and both quote 24-hour and 20+ hour runtimes respectively. Lococo specifically advises pairing the device once indoors before you fly, so do that the night before.
