• MARLALL's biggest strength: an IP68 sealed, bone-conduction open-ear design with 32 GB of built-in MP3 storage, so music keeps playing underwater where Bluetooth physically cannot reach.
• MARLALL's biggest trade-off: no noise control at all, and Bluetooth only works above the surface — you must switch to MP3 mode in the water and dry the mic after every swim.
• TCXCEO's biggest strength: real-time AI translation across 134+ languages with an LCD touch screen, plus active noise cancellation and a transparency/aware mode for hearing your surroundings.
• TCXCEO's biggest trade-off: only IPX6 water resistance — fine for rain, sweat and splashes, but not built for immersion, and it has no on-board music storage.
• Who MARLALL is for: swimmers, snorkelers, open-water athletes and anyone who wants audio without plugging their ears.
• Who TCXCEO is for: travellers, business users and anyone who needs to understand and be understood in another language.
The MARLALL set is built around one very specific problem: how do you listen to music while your head is underwater? Bluetooth signals don't travel through water, so MARLALL sidesteps the issue entirely with 32 GB of internal memory. You load playlists over the magnetic charging cable, switch the unit into MP3 mode, and the audio keeps going lap after lap — around 8,000 songs' worth of storage if you want to fill it. That is the whole trick, and it's a genuinely smart one.
The second half of the design is the bone-conduction driver. Instead of sealing a speaker into your ear canal, it sends vibrations through your cheekbones to your inner ear. That means your ears stay completely open. In a pool that's useful for hearing lane mates and whistles; on a bike or a run it's a real safety argument, because traffic noise still reaches you. The frame is liquid silicone, weighs about 29 g, and uses adjustable straps so it stays put without clamping down. IP68 covers immersion, sweat, rain and dust, so pool water and saltwater aren't a concern.
Who should buy it: lap swimmers, snorkelers, boaters, marathon runners and cyclists who want audio without blocking the world out. Who should skip it: anyone who wants active noise cancellation. The noise control field on this model is literally "none" — there's no ANC and no aware mode to toggle, because the open-ear design is the awareness. Also skip it if you mainly want hands-free calls in noisy places; the mic needs drying after a swim before calls behave properly. Pairing is Bluetooth 5.4 with roughly a 10-metre range for above-water use.
The TCXCEO NE20 is a different animal entirely. Its headline feature is live AI translation across 134+ languages and accents, which is the kind of thing that turns a stressful foreign trip or a mixed-language meeting into something manageable. You control it through an LCD touch screen on the charging case — music, calls and translation modes all switch with a tap — and it supports five separate translation modes, so you can pick the setup that fits a face-to-face chat versus a presentation.
The audio side is where it separates itself from the MARLALL. These are conventional in-ear buds with Active Noise Cancellation, so they actively block out airport terminals, open-plan offices and train carriages. Crucially, they also include a transparency mode, which is the aware-mode equivalent: you flip it on and the outside world comes back in without removing the buds. That's the feature you want when you're ordering coffee in a language you're still learning, or when you need to hear an announcement while your ANC is running.
Durability is IPX6, which handles sweat, rain and gym sessions but not swimming. Battery is quoted at up to 60 hours total — roughly 5 hours per charge topped up repeatedly by the case — which covers long travel days and back-to-back meetings without hunting for a socket. Who should buy it: frequent flyers, business travellers, language learners and anyone who regularly works across languages. Who should skip it: swimmers and anyone who wants on-board music storage with no phone nearby, because this set has none.
• Best for swimming and water immersion → MARLALL Swimming Headphones-Bone Conduction (IP68, MP3 mode underwater).
• Best for translating live conversation → TCXCEO AI Translation Earbud (134+ languages, five translation modes).
• Best for aware mode and staying alert to your surroundings → TCXCEO AI Translation Earbud, which pairs ANC with a transparency mode you can switch on and off. MARLALL's awareness is permanent and passive — it comes from the open-ear shape, not a setting.
• Best for blocking out noise → TCXCEO AI Translation Earbud (active noise cancellation). MARLALL has no noise control whatsoever.
• Best for battery endurance on a trip → TCXCEO AI Translation Earbud (up to 60 hours total with the case).
• Best for listening without a phone → MARLALL Swimming Headphones-Bone Conduction (32 GB internal storage, roughly 8,000 songs).
• Best for rain, sweat and gym use → a tie, in my view. MARLALL is IP68 and TCXCEO is IPX6; both shrug off sweat and weather, but only MARLALL is rated for going under.
• Best for running and cycling safety → MARLALL Swimming Headphones-Bone Conduction (open ears, 29 g, adjustable straps).
If I had to pick one, I'd pick based on the water. In my opinion, the MARLALL Swimming Headphones-Bone Conduction is the more specialised and more impressive piece of engineering — internal storage plus IP68 plus bone conduction solves a problem almost nothing else solves, and the open-ear build doubles as built-in awareness for runners and cyclists. But if you don't swim, the TCXCEO AI Translation Earbud is the more useful everyday pair: ANC, transparency mode, a touch screen and live translation in 134+ languages. Buy MARLALL for the pool. Buy TCXCEO for the airport.
how to turn on aware mode on bose headphones
On Bose models, aware mode is usually toggled through the Bose app or by cycling the noise-control button on the earcup until you reach the aware setting. Note that this page is about the MARLALL and TCXCEO products, not Bose — the equivalent on the TCXCEO AI Translation Earbud is its transparency mode, which you switch on via the LCD touch screen.
how to turn off aware mode on jlab headphones
JLab headphones typically cycle through noise-cancelling and aware/be-aware settings with a button press or through the JLab app. For the products compared here, the relevant control is on the TCXCEO AI Translation Earbud: transparency mode is turned off from the touch screen, which returns you to full Active Noise Cancellation.
what is ambient aware on headphones
Ambient aware (or transparency) mode uses the microphones to pipe outside sound into your ears so you can hear traffic, announcements or a conversation without removing your headphones. The TCXCEO AI Translation Earbud offers exactly this alongside its ANC, while the MARLALL Swimming Headphones-Bone Conduction achieves a similar effect permanently by design — its bone-conduction open-ear shape never blocks your ear canal.
how to turn off aware mode bose headphones
On Bose headphones you'd normally press and hold the noise-control button or use the app to drop back to quiet mode. If what you actually want is the ability to shut out the world on the TCXCEO AI Translation Earbud, just switch transparency off on the LCD touch screen and ANC takes over. The MARLALL has no aware mode to disable, since it has no noise control at all.
