How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a tiny plug-and-play transmitter that turns any wired 3.5mm audio jack — including an airplane seat's entertainment system — into a Bluetooth feed for your own headphones, choose SUNITEC Airplane; if you need a complete pair of over-ear headphones that do the noise cancelling and the listening in one device, choose Silensys Hybrid Active Noise.
• SUNITEC Airplane — biggest strength: wireless audio from any 3.5mm jack, with aptX/aptX Adaptive/aptX HD support, dual-headphone sharing, and up to 35 hours of use per charge.
• SUNITEC Airplane — biggest trade-off: it is not a headphone. It has no drivers and no earpads, so you must already own a Bluetooth headphone or earbud to hear anything.
• Silensys Hybrid Active Noise — biggest strength: it is a self-contained over-ear headphone with hybrid active noise cancellation, 40mm dynamic drivers, memory foam earpads, and ENC-enhanced call clarity.
• Silensys Hybrid Active Noise — biggest trade-off: its battery is shorter — up to 30 hours of playback, dropping to about 25 hours with ANC switched on.
• Who SUNITEC Airplane is for: frequent flyers and gym-goers who want to keep using their favourite wireless headphones with older wired equipment.
• Who Silensys Hybrid Active Noise is for: anyone who wants one finished product that cancels noise, plays music, and takes calls without extra gear.
The SUNITEC Airplane (model BT200B) is a Bluetooth 5.3 transmitter that plugs into a 3.5mm auxiliary jack and rebroadcasts that audio wirelessly. It runs on a Qualcomm chipset, which is what the spec sheet credits for its anti-interference behaviour and connection stability. Codec support covers aptX, aptX Adaptive and aptX HD, so the wireless link is designed for low latency and high-fidelity playback rather than a basic SBC handshake. If your headphones support those codecs, that matters; if they don't, the adapter still works, it just falls back to a more standard stream.
In practice, it's a jack-of-all-trades for wired sources. The obvious use is a plane seat's armrest audio socket — plug in the dongle, pair your own AirPods or over-ears, and watch the in-flight movie without dragging out a cable. But the same trick works on a treadmill with an older console, a Nintendo Switch in handheld mode, a projector, or any tablet or TV with a headphone port. The dual-headphone connection is the sleeper feature: two Bluetooth headphones can share the same stream, which is genuinely useful if you're travelling with someone and both of you want the same movie.
It's small — roughly 2.4 by 0.5 by 1 inches, weighing about 20 grams — and the body is black plastic with touch controls. The battery is a 3.7V lithium cell rated for up to 35 hours of continuous use, and it charges over USB-C. It ships with the battery included.
Silensys Hybrid Active Noise: Who It's For
The Silensys Hybrid Active Noise (model SE7) is a different category entirely: a wireless over-ear headphone in gold, with hybrid active noise cancellation that generates inverse sound waves to neutralise ambient noise. That's the classic ANC approach, and it's aimed squarely at airplanes, trains and noisy streets. Build is plastic with over-ear placement, and the earpads are memory foam with a padded, adjustable headband — a combination chosen for pressure distribution over long sessions rather than a tight clamp.
Audio comes from custom 40mm dynamic drivers with a frequency range of 20Hz to 20,000Hz. That's the full audible band, and Silensys tunes it toward a well-balanced profile with emphasised bass — the spec sheet calls out deep punch, vocal clarity and fine detail. Calls get their own treatment: ENC (environmental noise cancellation) on the microphone side is designed to keep your voice intelligible on a busy street or in wind, which is the part most cheap headphones get wrong.
Battery life is up to 30 hours of playback, or about 25 hours with ANC running. That's the trade-off you accept for having the cancellation circuitry always available. Connectivity is Bluetooth 5.0, and there's a 3.5mm jack as well, so you can go wired when the battery is flat or when a source is analogue-only. The package includes a cable and a user manual, and the warranty runs 18 months.
Who should skip it? Someone who already owns premium headphones and only needs them to talk to a plane's seat socket — the SE7 replaces your headphones rather than adapting them. And if you specifically want the lowest-latency codec support for gaming, the SE7's sheet doesn't list aptX, so the SUNITEC's codec story is stronger there. For everyone else — commuters, remote workers, students, long-haul flyers — this is the self-contained answer.
Side-by-Side: Which Should You Choose?
• Best for using your own headphones on a plane → SUNITEC Airplane. It converts the seat's 3.5mm output to Bluetooth so your existing earbuds or over-ears do the work.
• Best for battery life → SUNITEC Airplane. Up to 35 hours versus up to 30 hours (about 25 with ANC on).
• Best for watching a movie with a travel companion → SUNITEC Airplane. Dual headphone connection lets two Bluetooth headsets share one audio stream.
• Best for calls and remote work → Silensys Hybrid Active Noise. ENC microphone processing plus over-ear isolation is a better fit for meetings than a transmitter with no mic of its own.
• Best for low-latency, high-fidelity wireless codecs → SUNITEC Airplane. aptX, aptX Adaptive and aptX HD support is unusual at this level of accessory.
• Best for gaming on a Switch or a treadmill session → SUNITEC Airplane. Both are 3.5mm-jack scenarios, which is exactly what this dongle is built for.
• Best for one-and-done simplicity → Silensys Hybrid Active Noise. No pairing dance with a second device, no dependency on what's already in your bag.
In my opinion, these two barely compete — they solve different problems, and the honest answer is that most people shopping this comparison want the Silensys SE7. If you don't already own a decent Bluetooth headphone, the SUNITEC is dead weight: it has nothing to transmit to. Buy the SE7 if you want noise cancelling, 40mm drivers, memory foam comfort and a mic in a single package, and accept the roughly 25-hour ANC runtime.
I'd pick the SUNITEC Airplane only in one specific situation: you already love your headphones, you fly often, and you're tired of airline-supplied audio. Then it's the better tool, and the dual-headphone trick is a genuine bonus. For everyone else, the Silensys Hybrid Active Noise is the more complete purchase.
No. It's a Bluetooth transmitter with a 3.5mm AUX plug and no speakers or earpads. You pair your own Bluetooth headphones to it. That's why it's cheap to carry and useless without a second device.
Yes, for its own audio — it's a standalone wireless headphone. It also has a 3.5mm jack, so you can plug it directly into a seat's audio socket with a cable if you'd rather not use Bluetooth.
Only the Silensys has real ANC hardware — hybrid active noise cancellation designed to neutralise ambient sound. The SUNITEC's job is audio transmission, not isolation, so if quiet is your priority, the SE7 is the one to consider.
The two sit in different accessory categories, and I won't guess at numbers. Check the current price on Amazon for each — the page's button takes you there — and weigh it against what you already own. If you own good headphones, the SUNITEC is the smaller outlay; if you don't, the Silensys saves you buying two things.
