• iClever BTH13 — biggest strength: Kid-focused safety and comfort, with a volume limiter that switches between 74 and 85 dBA and stays locked, plus a soft adjustable headband and foldable over-ear design for ages roughly 3–16.
• iClever BTH13 — biggest trade-off: No active noise cancellation and a bulky over-ear shape that is not meant for workouts or slipping into a pocket.
• XIAOWTEK Earbuds — biggest strength: True wireless freedom with Bluetooth 5.4, up to 50H total playback, a dual LED battery display and IP7 waterproofing for sport and commuting.
• XIAOWTEK Earbuds — biggest trade-off: In-ear buds fit every ear differently, there is no volume limit for children, and there is no wired AUX fallback when the battery runs out.
• Choose iClever BTH13 if you are buying for a child and want a safe, durable, travel-friendly headphone with a wired backup.
• Choose XIAOWTEK Earbuds if you are buying for yourself and want discreet, sweat-proof earbuds for calls, gym sessions and daily listening.
The BTH13 is, first and foremost, a safety product dressed up as a fun one. The headline feature is the volume limiter: you press the "+" and "-" buttons at the same time to switch between 74 dBA and 85 dBA, and once it is set it does not drift. For a parent, that is the whole ballgame. Kids' ears are more sensitive than adults', and a child who grabs the controls and mashes the volume up cannot push past the ceiling you chose. That single design decision tells you exactly who this headphone was built for.
Around that core, iClever adds the things a kid actually cares about. The RGB LED cat ears are controlled by their own dedicated button, and pressing it in Bluetooth mode turns the lights off to stretch battery life — a neat bit of engineering that lets the fun feature exist without wrecking runtime. The 40 mm dynamic drivers cover a 20 Hz–20,000 Hz range at 32 ohm, which is standard, listenable territory rather than audiophile gear, and that is fine for cartoons, school videos and pop music. The over-ear pads are leather, the headband is silicone and adjustable, and the whole thing folds up for travel. At 173 g it is light enough for a child to wear through a long car ride or flight.
Connectivity is more generous than you would expect at this tier. You get Bluetooth plus a 3.5 mm AUX jack, so the headphones still work on a plane seat-back screen or a tablet with a dead battery. The claimed battery life is 50 hours, and since the lights can be switched off, real-world runtime should hold up on trips.
Who should skip it? Anyone buying for themselves. There is no noise cancellation, the over-ear shell is bulky, and the styling is unmistakably for kids. If you want earbuds for the gym, this is the wrong product entirely.
The XIAOWTEK S66 is the opposite philosophy: small, light and built to disappear. The earbuds weigh about 4.5 g each, sit in an oval in-ear shape, and use Bluetooth 5.4 for a stable connection with one-step auto-pairing — take them out of the case and they connect. That frictionless routine is what makes true wireless earbuds genuinely useful rather than a hassle, and it is the right call for a product aimed at commuters, office workers and gym-goers.
The spec sheet leans hard into everyday practicality. You get up to 8 hours of playback on a single charge with a 1.5-hour recharge, and up to 50 hours total with the charging case. The dual LED digital display shows the battery level of both the buds and the case, which sounds minor until you have owned earbuds that died without warning mid-call. The 13.4 mm graphene diaphragm drivers are larger than typical budget earbuds, pointing to stronger bass and clearer mids, and the dual hybrid ENC microphones are designed to passively cut around 85% of background noise for calls — the kind of feature that matters when you are taking a meeting on a noisy street.
Touch controls cover volume, track skipping, play/pause, call answering and voice assistant, and the buds work with iOS, Android, TVs, computers and laptops. IP7 waterproofing and a sweat-proof build make them a sensible pick for running and gym work. The trade-offs are honest ones: in-ear fit is personal and can take some tip-swapping to get right, there is no wired jack as a fallback, and there is no child volume limit — this is an adult's product. Note also that the "noise cancelling" in the title refers to the call microphones, not active noise cancellation for your music.
• Best for young children → iClever BTH13. The 74/85 dBA limiter is the deciding feature; nothing on the XIAOWTEK side protects a child's hearing.
• Best for battery life → a tie on paper (both claim 50H), but iClever BTH13 wins for trips because the AUX cable means zero battery anxiety on a plane.
• Best for workouts and running → XIAOWTEK Earbuds. IP7 waterproofing and 4.5 g per bud beat a 173 g over-ear headphone every time.
• Best for calls → XIAOWTEK Earbuds. Dual hybrid ENC microphones with around 85% background noise reduction are built for exactly this.
• Best for long wear comfort at home → iClever BTH13. Over-ear leather pads spread pressure better than in-ear tips over several hours.
• Best for travel with kids → iClever BTH13. Foldable, adjustable, silicone headband and a wired backup for seat-back entertainment.
• Best for compatibility with older devices → iClever BTH13. The 3.5 mm jack covers anything without Bluetooth.
• Best for a pocket-sized daily carry → XIAOWTEK Earbuds. A charging case with an LED battery readout is far easier to live with than a full headphone.
If I were buying for a child, I would buy the iClever BTH13 without hesitating — in my opinion the locked volume limiter, the adjustable silicone headband and the AUX fallback make it the more responsible and more versatile choice for a young listener. If I were buying for myself, I would take the XIAOWTEK Earbuds: Bluetooth 5.4, the LED battery display, IP7 waterproofing and the ENC call mics are the features I would actually use every day. The two products are not really rivals — they serve different people. Match the product to the wearer, not to the spec list.

FAQ
Only for calls. The dual hybrid ENC microphones passively reduce about 85% of background noise so your voice comes through clearly. There is no active noise cancellation for your music — the spec sheet lists noise control as none.
Both claim up to 50 hours. The iClever figure is headphone runtime, and you can extend it by switching off the LED lights. The XIAOWTEK figure combines roughly 8 hours per charge with the charging case, and the LED display shows remaining power.
Yes. They are IP7 waterproof and sweat-proof, weigh about 4.5 g each, and use Bluetooth 5.4 for a stable connection — a sensible fit for sport. Just remember there is no wired option if the battery runs flat.
