How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want one pair of earbuds that translates live conversations, cancels noise hard, and runs for days between charges, choose Relxhome NE20; if you need volume-limited headphones built specifically to protect a child's hearing at school or on a flight, choose SIMOLIO Kids Headphones.
• Relxhome NE20 – biggest strength: Real-time AI translation across 140 languages plus 48dB active noise cancellation and a very long 60-hour battery figure, all controlled from an LCD touchscreen.
• Relxhome NE20 – biggest trade-off: Translation depends on the companion app plus a stable network and Bluetooth connection, so it is an adult tool with a phone-tethered learning curve.
• SIMOLIO Kids Headphones – biggest strength: Three switchable volume limits (85dB / 94dB / 104dB) with both wired and wireless Bluetooth options and audio sharing, aimed squarely at protecting young ears.
• SIMOLIO Kids Headphones – biggest trade-off: The feature set is deliberately narrow — no translation, no active noise cancellation, no touchscreen hub — so it is a child's headphone and little else.
• Who each is for: Relxhome NE20 for adults who work, travel, game and talk across languages; SIMOLIO Kids Headphones for parents buying a first safe pair for a child.
The Relxhome NE20 is a pair of in-ear earbuds that tries to be several gadgets at once. The headline act is AI-powered, face-to-face translation across 140 languages, which is the kind of thing you notice the first time you are standing in front of someone who does not share your language. Around that sit proper adult-headphone specs: 48dB active noise cancellation, a 45ms low-latency mode for gaming, a six-microphone array for calls, and Bluetooth 5.4 with a 10-metre range. The battery figures are the part that matters most day to day — 60 hours total average life, with 6 to 8 hours per charge — which is the difference between charging nightly and charging once a week.
What makes the NE20 unusual is the charging case itself. It carries an LCD touchscreen that handles music, calls and translation, and doubles as a small lifestyle hub where you can set alarms, switch noise modes, or play a stress-relief game on a commute. The buds are in-ear, made from plastic and silicone, finished in white, and light at 0.12 kg for the set. Controls are touch-based, there is no headphone jack, and the frequency range is a standard 20 Hz to 20,000 Hz with a dynamic driver at 32 ohm impedance.
In my opinion, this is a buy for the frequent traveller, the person in back-to-back calls, the commuter in a loud city, and anyone who regularly deals with people who speak another language — multicultural families included. Skip it if you want simple headphones for a young child, or if you dislike app-based features. The translation side only works through the companion app, and it needs a stable network and Bluetooth connection; weak connectivity can cause delays or outright failure. That is a real dependency, and it is the honest trade-off for what the earbuds do.
The SIMOLIO Kids Headphones are built around one idea: getting the volume limit right. The specs list three switchable safe volume limits — 85dB, 94dB and 104dB — which gives a parent a way to cap loudness at a genuinely protective level for younger children and step it up a notch for older kids in noisier places, like a plane cabin or a busy classroom. That single design decision is the whole point of the product, and it is the reason it exists alongside ordinary headphones.
The second thing that matters is versatility in connection. These are both wired and wireless Bluetooth headphones, so they work with a tablet or laptop over Bluetooth and still work with anything that needs a cable — a school device, a seat-back entertainment system, a hand-me-down tablet with a headphone port. The audio sharing feature means two pairs (or a pair and a parent's device) can listen to the same thing, which is genuinely useful on long journeys when one screen has to serve two children.
Beyond that, the sheet is deliberately thin: the listing frames them as school and travel headphones for girls and boys, and the brand is SIMOLIO. There is no active noise cancellation here, no translation, no touchscreen, no gaming latency mode. In my opinion, that is not a flaw — it is focus. Buy these for a child who needs a safe, simple, volume-capped pair for school, car rides and flights. Skip them if you are shopping for yourself, if you want noise cancelling for a commute, or if you need any kind of smart feature. This is a child's headphone, and it behaves like one.
• Best for live translation → Relxhome NE20. 140 languages, real-time face-to-face, though only through the app and with a stable connection.
• Best for hearing protection → SIMOLIO Kids Headphones. Three switchable limits at 85dB, 94dB and 104dB are the entire reason to buy them.
• Best for battery life → Relxhome NE20. A 60-hour total figure with 6–8 hours per charge is a different category from anything a child's headphone typically offers.
• Best for quieting a noisy environment → Relxhome NE20. 48dB active noise cancellation is a feature the SIMOLIO simply does not have, and it matters most on planes, trains and open-plan offices.
• Best for a first pair for a child → SIMOLIO Kids Headphones. Wired and wireless options, plus audio sharing, fit school bags and shared screens far better than adult earbuds.
• Best for gaming and calls → Relxhome NE20. 45ms low latency and a six-microphone array are aimed straight at lag-free play and clear conference calls.
• Best for simplicity → SIMOLIO Kids Headphones. No app, no account, no network dependency — plug in or pair and go.
• Best for adult daily carry → Relxhome NE20. Light in-ear build, touch controls, a 10-metre Bluetooth range and a case that doubles as a control screen.
If I were spending my own money on one of these for myself, I would buy the Relxhome NE20. Translation across 140 languages, 48dB noise cancellation, 45ms latency and a 60-hour battery figure make it the far more capable device for an adult who travels, takes calls and works in noisy places — provided you accept the app and network dependency. But I would not hand it to a child. For a kid, I would buy the SIMOLIO Kids Headphones and feel good about the 85dB/94dB/104dB limits, the wired-and-wireless flexibility and audio sharing. Two different jobs, two different answers.
FAQ
No. The sheet lists the age range as adult, and the translation features rely on an app plus a stable network and Bluetooth connection. For a child, volume-limited kids' headphones are the safer and simpler choice.
You can use the earbuds for audio and calls over Bluetooth without translating, but the translation feature works only through the companion app and needs a stable network and Bluetooth connection. Poor connectivity can cause delays or failures.
They are aimed at different buyers, so value depends on the job. If you need translation, noise cancellation and long battery, the NE20 does more per pair. If you need a safe, simple pair for a child, the SIMOLIO covers that need directly. Either way, check the current price on Amazon before deciding.
