If you want a wireless, app-tunable everyday headphone with marathon battery life, choose SONY WH-CH520; if you need a wired, volume-limited USB-C headphone built specifically for kids, choose Botesty Sound USB C Headphones. These two products barely overlap. One is a Bluetooth on-ear for adults who want freedom from cables. The other is a corded over-ear designed to protect young ears. Picking between them comes down to who's wearing them and how they'll be used.
• SONY WH-CH520 — biggest trade-off: It's wireless only, with no headphone jack and no active noise canceling, so you'll need to manage charging and you'll still hear the world around you.
• Botesty Sound USB C Headphones — biggest strength: A USB-C wired connection with a switchable volume limit (85/94 dB), built for kids' ears and plug-and-play on tablets and laptops.
• Botesty Sound USB C Headphones — biggest trade-off: It's corded, so there's no freedom of movement, and it targets children rather than adult listeners who want richer audio and app controls.
• Who each pick is for: Choose the SONY WH-CH520 for teens and adults who want wireless convenience; choose the Botesty Sound USB C Headphones for younger kids who need safe, simple, wired listening.
The WH-CH520 is a lightweight on-ear Bluetooth headphone — about 147 g — that Sony clearly designed for people who wear headphones for hours at a time. The swivel earcups and adjustable headband with a soft head cushion mean it slips on and off easily and folds for carrying. If you commute, study, or work through long stretches with music or podcasts on, that comfort-first build matters more than fancy extras.
Who should buy it: anyone who wants a wireless, cable-free daily driver with class-leading battery, app-based sound tweaking, and the convenience of switching between two devices. It's available in six colors, so there's room to match your style. Who should skip it: people who need a wired connection they can trust with zero charging, travelers who want active noise canceling (this model has none), or anyone shopping for a young child — the on-ear fit and adult-focused feature set aren't aimed at small heads. Also note it's Bluetooth-only, with no 3.5 mm jack, so it won't work with non-Bluetooth gear.
Botesty Sound USB C Headphones: Who It's For
The Botesty Sound USB C Headphones (model "Ivy") are a different animal entirely. These are wired over-ear headphones that connect through a USB-C plug, aimed squarely at kids and teens. The standout safety feature is a switchable volume limit — 85 dB or 94 dB — which lets a parent cap how loud the audio can get. That's a meaningful design choice for school-age kids, and it's the kind of thing adult-focused headphones rarely bother with.
Because the connection is wired USB-C, there's no battery to charge and no pairing to fumble with. Plug them into a tablet, iPad, or laptop with a USB-C port and they just work — handy for school, airplane travel, or screen time at home. The over-ear design cups the whole ear rather than pressing on it, which tends to suit younger wearers, and the gradient blue finish gives them a kid-friendly look. A built-in mic handles calls or classroom needs, and the controls are simple push buttons rather than an app.
Who should buy it: parents buying for younger children who need safe volume, a tangle-resistant simple setup, and a wired connection that won't die mid-flight. Who should skip it: adults who want wireless freedom, rich app-based EQ, or long battery life. The 32-ohm impedance and wired-only design also mean it's tethered to whatever it's plugged into, and it won't connect to devices without a USB-C port. It's a purpose-built kids' headphone, not an all-rounder for grown-ups.
• Best for battery life → SONY WH-CH520. Up to 50 hours on a charge, with quick charging for short top-ups.
• Best for safe listening with kids → Botesty Sound USB C Headphones. The 85/94 dB volume limit is the deciding feature here.
• Best for wireless freedom and multipoint → SONY WH-CH520. Bluetooth 5.2 and two-device pairing let you switch between phone and laptop.
• Best for plug-and-play simplicity → Botesty Sound USB C Headphones. Wired USB-C means no charging and no pairing.
• Best for app-based sound customization → SONY WH-CH520. EQ Custom and DSEE live in the Sony Headphones Connect app.
• Best for school, travel and tablets → Botesty Sound USB C Headphones. Over-ear comfort, a USB-C plug, and a kid-focused build.
• Best for all-day comfort on adult heads → SONY WH-CH520. The lightweight 147 g build, swivel cups and head cushion are made for long sessions.
• Best for noise control → neither, honestly. Both list no active noise canceling, so don't expect silence from either.
In my opinion, the SONY WH-CH520 is the better buy for most people, because it covers the widest range of everyday situations — wireless freedom, huge battery life, multipoint switching, and app-tuned sound — in a light, comfortable frame. I'd pick it without hesitation for commuting, studying, and travel. But if you're shopping for a young child, I'd buy the Botesty Sound USB C Headphones instead: the volume limit and wired USB-C simplicity are exactly what a kid's headphone should prioritize. Match the pick to the wearer, and you won't go wrong either way.
For younger children, the Botesty Sound model — its 85/94 dB volume limit and wired USB-C design are built with kids in mind. The SONY is better suited to teens and adults.
No. Sony lists noise control as "None" for this model, so it doesn't actively cancel noise. The Botesty Sound headphones also list no noise canceling.
No. They're wired-only, connecting through a USB-C plug with no Bluetooth. The SONY WH-CH520 is the wireless option here, using Bluetooth 5.2.
Pick the SONY WH-CH520 for wireless everyday use and the Botesty Sound model for kids' safe wired listening. Prices change, so check the current price on Amazon before you decide.
