• Voopwink USB Type C biggest strength: limited volume at 85dB/94dB with full over-ear coverage and a stainless-steel adjustable headband — a design clearly aimed at protecting young ears.
• Voopwink USB Type C biggest trade-off: it is a kids' headset first, so the tuning and build target durability and comfort rather than critical listening; it is also over-ear, which is bulkier than earbuds.
• AZLA APL-120C biggest strength: a lively pop/K-POP tuning with an 8mm dynamic driver, low 16Ω impedance and 104dB sensitivity, plus four eartip sizes for a secure fit.
• AZLA APL-120C biggest trade-off: in-ear only, no volume limiting, and no active noise control — it is a general-purpose earbud, not a child-safety product.
• Who each is for: Voopwink USB Type C for parents buying for kids, teens and school use; AZLA APL-120C for older listeners who want portable, energetic wired earbuds for music and calls.
The Voopwink USB Type C is a wired, over-ear kids' headset with a USB-C jack and a built-in microphone. The headline feature is the limited volume at 85dB and 94dB — two capped listening levels that keep output within a controlled range. For a parent handing a child a tablet, that is the whole point. The ear cups are over-ear, so the earmuffs fully cover a child's ears rather than pressing into them, and they use soft, breathable protein padding. That combination matters for long sessions: a kid watching a movie or listening to an audiobook on a road trip is not going to keep adjusting a pair that pinches.
The headband is the other practical piece. It adjusts across a wide range, so the same pair fits toddlers, teens and even adults, and the stretching section is stainless steel rather than plain plastic. In my opinion, that is the detail that decides whether a kids' headphone survives a school year. Add a foldable design that slips into a school bag or suitcase, and you have a product designed around being carried, dropped and re-used. It is also worth noting the blue color and fabric-and-plastic enclosure — a straightforward, child-friendly look rather than a fashion statement.
Who should buy it: parents and guardians buying for school, online classes, travel by plane, car or bike, and anyone who wants a wired USB-C headset with a microphone and a hard volume ceiling. Who should skip it: adults who want serious music quality, anyone who prefers the low profile of in-ear buds, and listeners who need noise cancellation — the Voopwink does not offer it. If you are shopping for yourself and music is the priority, this is probably not your pair.
The AZLA APL-120C is a wired in-ear earbud with a USB-C plug and an inline microphone. AZLA describes the tuning as lively, aimed at the energy of K-POP and modern pop, with clear vocals and treble, and distortion-free sound. The underlying hardware supports that pitch: an 8mm dynamic driver, 104dB SPL/mW sensitivity at 1kHz, and 16Ω impedance at 1kHz. Low impedance and high sensitivity together mean these buds are easy to drive — a phone or tablet with a USB-C outlet will get loud output without needing a dongle or amp.
The fit story is unusually complete for this category: four sizes of eartips are included, which matters because in-ear sound depends heavily on a proper seal. A good seal gives you the bass and isolation; a bad one leaves the sound thin. Four sizes means most people can find that seal, and AZLA specifically mentions a secure fit during active use. The inline controller handles calls, music and volume, so you are not reaching for your phone constantly. The design is inspired by the Korean moon jar — a minimal, elegant white look — which is a nice touch if you care how your earbuds read in public.
Who should buy it: commuters, students and everyday listeners who want compact wired earbuds for pop and vocals, and anyone with a USB-C phone, tablet or laptop who wants a mic and inline controls. Who should skip it: parents looking for a volume-limited kids' product, listeners who want over-ear coverage, and anyone who needs active noise cancellation — the AZLA lists no noise control at all. If you want isolation, you get it from the eartip seal, not from electronics.
• Best for young children and school use → Voopwink USB Type C. The 85dB/94dB limited volume and over-ear coverage are designed for exactly this.
• Best for pop, K-POP and vocal-forward music → AZLA APL-120C. The tuning and the 8mm dynamic driver are aimed at lively, energetic sound.
• Best for fitting different head sizes in one household → Voopwink USB Type C. The adjustable stainless-steel headband spans toddlers through adults.
• Best for portability → AZLA APL-120C. In-ear buds with four eartip sizes take up far less space than over-ear cups.
• Best for easy volume control without touching your phone → AZLA APL-120C. The inline controller covers calls, music and volume.
• Best for long-wear comfort on a child → Voopwink USB Type C. Breathable protein padding and full over-ear coverage reduce pressure over long sessions.
• Best for a shared USB-C device (iPhone 15/16/17, Samsung, Android, iPad, tablet) → either. Both are wired USB-C. The difference is the form factor, not the plug.
• Best if you need noise cancellation → neither. The Voopwink lists none and the AZLA explicitly lists noise control as none.
If the headphones are for a child, I would buy the Voopwink USB Type C. The limited volume at 85dB/94dB, the over-ear coverage, the flexible stainless-steel headband and the foldable build all point at one job — surviving daily use by a kid without putting their ears at risk. If the headphones are for you and you mostly listen to pop or vocals on the move, I would buy the AZLA APL-120C instead: the 16Ω/104dB spec makes it easy to drive, the tuning is built for energy, and four eartip sizes give you a real chance at a proper seal. In my opinion these are not competitors so much as two different jobs wearing the same USB-C plug. Check the current price on Amazon for both before you decide.
FAQ
Yes. AZLA lists it as compatible with iPhone 15/16/17, Samsung and Android devices with USB-C outlets. It is a wired USB-C earbud with an inline mic and controller, so it needs a USB-C port — not a Lightning port — to work.
For music, I would lean toward the AZLA APL-120C. Its 8mm dynamic driver, 104dB sensitivity and 16Ω impedance make it easy to drive, and it is tuned for lively pop and clear vocals. The Voopwink is built around safe, capped volume for children rather than sound quality, so it is not the pick for critical listening.
No. The AZLA APL-120C lists noise control as none, and the Voopwink USB Type C lists no noise-cancelling feature. The AZLA's in-ear design and four eartip sizes can give you some passive isolation from a good seal, but neither product offers active noise cancellation.
