How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wireless, app-tunable everyday headphone for music, calls and podcasts, choose Sony WH-CH520; if you need a wired, kid-friendly headset with a boom mic and built-in volume limits for school, chat and gaming, choose SIMOLIO Over Ear Headphones.
• Sony WH-CH520 — biggest strength: fully wireless Bluetooth 5.2 with multipoint, up to 50 hours of battery life and a 3-minute quick charge that yields about 1.5 hours of playback.
• Sony WH-CH520 — biggest trade-off: on-ear design with no wired jack and no active noise cancellation, so it's not the pick for wired classrooms or for blocking out a noisy room.
• SIMOLIO Over Ear Headphones — biggest strength: a wired 3.5mm connection with a 330° swiveling noise-reducing boom mic, a one-key mute button and three levels of hearing protection — purpose-built for kids.
• SIMOLIO Over Ear Headphones — biggest trade-off: it's a corded headset, so there's no Bluetooth freedom and it's tethered to whatever device it's plugged into.
• Who the Sony is for: adults and teens who want a lightweight, wireless all-rounder for commuting, work-from-home calls and long listening sessions.
• Who the SIMOLIO is for: parents buying for children, teens and students who need a durable wired headset for virtual school, meetings and gaming.
The WH-CH520 is a wireless on-ear headphone built around convenience. Bluetooth 5.2 handles the connection, multipoint lets it stay linked to more than one device at a time, and pairing is simplified with Swift Pair and Fast Pair. There's no headphone jack at all, which tells you Sony designed this purely as a cord-free product. Controls are handled by buttons on the ear cups and by voice, and the on-board mic lets you take calls without pulling out your phone.
Battery is the headline here. Sony rates it at up to 50 hours of average life, and a 3-minute quick charge gets you roughly 1.5 hours of listening. In practice that means you can leave the USB-C cable at home for a week of normal use, and top up in the time it takes to make coffee. The audio side uses a dynamic driver covering 20 Hz to 20,000 Hz with 24-ohm impedance, and the Digital Sound Enhancement Engine (DSEE) is there to restore high frequencies for a more natural result. If you want to shape the sound, the EQ in the Sony Headphones Connect app lets you tune it to taste.
Comfort is the other selling point: an adjustable headband, soft ear pads and a lightweight build, finished in white with an ABS plastic and silicone enclosure. It's an on-ear fit, which some people love for breathability and others find less isolating than over-ear cups. There's no active noise cancellation listed, so this is a headphones-for-quiet-and-moderate-noise pick — great on a train, less great next to a jet engine.
Buy the Sony WH-CH520 if you want one wireless headphone for music, podcasts, audiobooks and calls, you value long battery life and quick charging, and you like the idea of app-based EQ. Skip it if you need a wired connection, a boom microphone that sits near your mouth, or volume-limiting for a child.
The SIMOLIO is a different animal entirely — it's a wired over-ear headset designed around kids, school and communication rather than around music on the move. The 3.5mm connection plugs into tablets, Chromebooks, iPads, smartphones, PS4, PS5, Xbox One, Switch and gaming consoles, and the included Y-audio adapter splits the signal so you can connect to both the audio and mic ports on a desktop computer. That's a genuinely useful detail for anyone doing virtual classes or meetings on a PC.
The microphone is the centerpiece. It's a 330° swiveling, flexible boom that you can position close to your mouth or flip out of the way when you're not talking. It's unidirectional and noise-reducing, meaning it focuses on picking up your voice rather than the room around you, and there's a one-key mute button for instant silencing — handy in a classroom or during an online lesson when you need to cough or talk to someone nearby. This is the headset you buy when the other person's ability to hear you clearly matters as much as your ability to hear them.
Then there's the child-focused part: three levels of hearing protection. For parents, that's the reason this product exists — you get a headset that's meant to keep volume in check for young ears. The enclosure is stainless steel, which suggests it's built to survive being stuffed in a backpack, and it ships with a protective case. The over-ear design also helps block some surrounding noise passively. Note the "adult" age range in the product details, which is worth reading alongside the kids-focused marketing so you know what you're getting.
Buy the SIMOLIO if you're outfitting a child, tween or teen for school, gaming or family calls, you need a boom mic with mute, and you want hearing-protection limits plus a wired connection that never needs charging or pairing. Skip it if you want wireless freedom, app EQ or a headphone for your own commute.

In my opinion, the Sony WH-CH520 is the better buy for most adults, because it does the widest range of everyday jobs — music, podcasts, calls, travel — without a cable, and the 50-hour battery plus quick charge means it rarely asks anything of you. The SIMOLIO Over Ear Headphones are the one I'd recommend without hesitation for a child or student, because the boom mic, mute button and hearing-protection levels are features the Sony simply doesn't try to offer. If you're shopping for yourself and want wireless, go Sony. If you're shopping for a kid in school, go SIMOLIO.

FAQ
Wireless only. It connects over Bluetooth 5.2 and has no headphone jack, so it can't be used with a 3.5mm cable.
No. They're a wired headset that runs off the 3.5mm connection, so there's no battery to charge or Bluetooth to pair.
Yes. The 3.5mm plug is compatible with PS4, PS5, Xbox One, Switch and other gaming devices, and the boom mic with mute is designed for in-game chat.
The SIMOLIO, in my opinion, because of the three levels of hearing protection, the stainless-steel build, the included protective case and the boom mic built for classroom and online use.
