How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a do-everything pair of wireless earbuds that translates 135 languages in real time and puts music, calls and a touchscreen case in one package, choose Hyyeosd NE20; if you need wired, zero-EMF air-tube earbuds with a plug-and-play 3.5mm jack and no battery to babysit, choose BUSMOV Air Tube Headphones.
• Hyyeosd NE20 — biggest strength: A 4-in-1 translation and audio device. Real-time two-way translation across up to 135 languages through the free Earjoy app, plus music, calls and a touchscreen charging case.
• Hyyeosd NE20 — biggest trade-off: It leans on your phone. The translation layer runs through the app, and you get up to 6 hours per charge (60 hours with the case), so it is not a set-and-forget accessory.
• BUSMOV Air Tube Headphones — biggest strength: The driver sits away from your ear and sound travels through hollow air tubes. That is the whole point: zero-EMF wired listening with no Bluetooth and no charging.
• BUSMOV Air Tube Headphones — biggest trade-off: Wired only, 3.5mm only, and a single 1-ohm impedance spec tells you nothing about sound tuning. If your phone dropped its headphone jack, you need an adapter.
• Pick Hyyeosd NE20 if you travel, study languages, take calls, and want one gadget that does translation and music.
• Pick BUSMOV Air Tube Headphones if you want a wired, radiation-free pair for kids, pregnancy, long calls or bedside listening.
The NE20 is not really a pair of earbuds. It is a translation device that happens to play music. The pitch here is a 4-in-1: real-time translation, music playback, phone calls, and an LCD touchscreen case. The translation side claims support for up to 135 languages and accents, with under 2 seconds of delay and over 98% accuracy, run through the free Earjoy app on iOS or Android. Six modes cover the way people actually use this: Free Talk, Online Translation, Speaker Mode, AI Chat, Photo Translation, and Voice Memos. Photo Translation and Speaker Mode are the ones that matter most on a trip — menu signs and face-to-face conversations.
The case is the sleeper feature. It has a color LCD touchscreen that handles 15+ functions directly: music playback, volume, EQ modes, language selection, alarms, a stopwatch, and even a remote camera trigger for your phone. That means you can leave your phone in your pocket more often than you would with typical earbuds. There is also a built-in AI assistant you can ask for quick answers or recommendations. Audio-wise you get a dynamic driver rated 20 Hz – 20,000 Hz, Bluetooth 5, touch controls on the buds, and sound isolation rather than active noise cancellation. Each bud weighs 8.2g, with skin-friendly silicone tips and an in-ear fit.
Who should buy it: travelers, students, language learners, and anyone in bilingual meetings or academic exchanges who wants translation and music in one device. Who should skip it: if you mostly want plain music earbuds and will never touch the translation features, you are paying for a lot of hardware you won't use — and the 6-hour-per-charge runtime is ordinary, even if the case stretches it to 60 hours total.
The BUSMOV pair takes the opposite approach: strip out the radio and the battery, and move the driver away from your head. Instead of an electronic driver firing directly into your ear canal, the driver sits in a remote pod and sound travels through hollow air tubes as pure air vibration. That is what makes them, in BUSMOV's framing, zero-EMF headphones — the pitch is aimed at pregnant women, nursing mothers, kids, and anyone thinking about long-term exposure.
The fit is designed around that idea too. The soft silicone in-ear tips rest at the entrance of the ear rather than pushing deep into the canal, so there is no pressure, no wax buildup, and no heat buildup over a long session. BUSMOV calls them a good match for online classes, gaming, kids' music, insomniacs listening to podcasts in bed, and long flights. The inline remote has dedicated volume +/– buttons and a multi-function button for play/pause and call answer/end, and the mic is tuned to isolate your voice from background noise — dogs, kids, traffic — for Zoom, Teams and phone calls. Construction is white silicone, in-ear, with a 1-ohm impedance rating and a two-year warranty. It is rated for both adults and kids.
Who should buy it: parents buying for children, anyone who wants a wired pair that never needs charging, people who take long calls and want their voice to come through clearly, and shoppers specifically trying to avoid Bluetooth radiation near the head. Who should skip it: if your phone has no 3.5mm jack (many recent iPhones and Pixels), you'll need an adapter, and if you want wireless freedom or translation features, this is not that product.
• Best for real-time translation → Hyyeosd NE20. 135 languages, six modes, sub-2-second delay claim, all through the free Earjoy app.
• Best for no-charging reliability → BUSMOV Air Tube Headphones. Wired 3.5mm, no battery, no pairing, always ready.
• Best for battery life → Hyyeosd NE20. Up to 6 hours per charge, up to 60 hours with the case. The BUSMOV pair has no battery to run down at all.
• Best for kids and sensitive ears → BUSMOV Air Tube Headphones. Shallow in-ear silicone tips, no deep insertion, rated for kids as well as adults.
• Best for travel and language learning → Hyyeosd NE20. Photo Translation, Speaker Mode and the touchscreen case are built for exactly that.
• Best for long calls and work-from-home → BUSMOV Air Tube Headphones. Noise-reducing mic plus inline volume and call controls, with no charge to manage.
• Best for a single all-rounder gadget → Hyyeosd NE20. Music, calls, translation and a remote camera trigger in one case.
• Best for anyone avoiding wireless radiation → BUSMOV Air Tube Headphones. Air-tube design, driver moved away from the ear, no Bluetooth radio.
In my opinion, most people shopping this comparison should buy the Hyyeosd NE20. It simply does more: translation in 135 languages, six translation modes, a genuinely useful touchscreen case, and solid everyday audio — and the 60-hour total runtime with the case covers a full trip. I would only steer you to the BUSMOV Air Tube Headphones if the zero-EMF, wired, no-charging angle is your whole reason for buying — for kids, pregnancy, or bedside listening. That is a real and specific need, and BUSMOV addresses it directly. But as a general-purpose pick, the NE20 wins on capability. Either way, check the current price on Amazon before you commit.
FAQ
No. They are wired with a 3.5mm jack, so there is no battery and no pairing. You plug them into a phone, laptop, tablet, console controller or airplane seat jack and they work. That also means no charging cable to remember.
The translation features run through the free Earjoy app on iOS or Android, so you need your phone for that part. The touchscreen case handles 15+ other functions — music, volume, EQ, alarms, stopwatch, remote camera — without pulling your phone out. The buds themselves are Bluetooth 5 wireless.
The BUSMOV Air Tube Headphones are the clearer fit. They are designed with shallow silicone tips that don't push into the ear canal, they are rated for both kids and adults, and the driver sits away from your ear with sound traveling through air tubes. The NE20 is a Bluetooth device aimed at adult travel and study use.
