If you want serious, certified hearing protection for a child in genuinely loud places, choose ProCase Noise Cancelling Headphones; if you need a wired USB-C headset with a microphone for calls, laptops and everyday listening, choose Cowyawn USB C Headphones. These two look similar in photos — over-ear, foldable, adjustable — but they are built for completely different jobs. One is a passive noise-blocking earmuff. The other is a plug-in audio headset. Here is how to tell which one actually belongs in your bag.
• ProCase's biggest strength: certified passive isolation (SNR 27 dB, ANSI S3.19 and CE EN352-1) from a solid ABS shell and thickened sound-absorbing foam — real hearing protection, not just muffling.
• ProCase's biggest trade-off: it plays no audio at all. It is an earmuff, not a headphone, and the fit is deliberately snug at first.
• Cowyawn's biggest strength: a wired USB-C connection with a built-in microphone, volume control and 40 mm dynamic drivers — plug in and you are on a call or listening in seconds.
• Cowyawn's biggest trade-off: no battery, no wireless freedom, and its isolation is passive only, so it will not tame a monster truck show.
• Buy ProCase if the goal is protecting a kid's ears (or an adult with sensory needs) at concerts, fireworks, air shows or while traveling.
• Buy Cowyawn if the goal is a cheap-to-own wired headset for a laptop, desktop, tablet or a USB-C phone.
ProCase's earmuffs are the adjustable-headphones story done properly for kids. The headband uses ergonomic telescopic arms that stretch up to roughly 32 mm (about 1.3 inch) on each side, so the same pair grows with a child instead of being outgrown in a season. That adjustability is the whole point: it is what makes these usable across different ages and head sizes without you buying a second set.
The isolation is the headline. A solid ABS shell plus thickened sound-absorbing foam gets you SNR 27 dB, backed by ANSI S3.19 in the US and CE EN352-1 in the EU. In practice that is the difference between a child covering their ears and screaming at a fireworks display and a child standing there calm. The 360° rotatable cups, ultra-soft cushions and skin-friendly padded headband keep the pressure reasonable, and the holeless pivot means hair does not get pinched in the hinge — a small detail that matters a lot to kids who hate having their hair pulled.
Two honest trade-offs. First, ProCase itself notes the fit is a little tight out of the box for more efficient isolation; the brand's own suggestion is to stretch it over a box for a day or two. Second, these are not headphones. There is no audio, no cable and no microphone. They are for autism and sensory needs, monster jam shows, airplane travel, sports events and theme parks — places where the goal is less noise, not more. Skip them if you wanted to listen to anything. This is also sold as a 2-pack, which suits families with more than one child but is overkill for a single user.
Cowyawn is the opposite kind of product: an actual listening device. It is a wired, over-ear USB-C headphone with a microphone, volume control and HD stereo sound, aimed at adults and teens. The 40 mm dynamic drivers and 32 ohm impedance are the standard recipe for something a phone or laptop can drive without a separate amp, and the 20 KHz frequency response covers the full range you would expect from everyday audio gear. Nothing exotic — just sensible specs for a plug-and-play headset.
The USB Type C jack is the reason to pick it. On a laptop, desktop or a USB-C phone, there is no dongle to lose and no pairing to fumble. Controls are on the earcup: touch control plus a button for volume, which is handy mid-call. The faux leather and plastic build with oval on-ear cups keeps it light at around 0.2 kg, and it folds for storage. It comes in a Tangerine colorway and carries a 1-year warranty description.
What you give up is freedom and quiet. This is a wired headset, so you are tethered, and "sound isolation" here means passive on-ear blocking — useful on a bus or in a shared office, useless against a jet engine or a pyrotechnics show. There is no battery to charge, which some people will love and others will find limiting. The on-ear (rather than over-ear) fit also means it rests on the ear instead of around it, which changes both comfort and how much outside noise gets in.
Side-by-Side: Which Should You Choose?
• Best for calls and meetings → Cowyawn USB C Headphones. Built-in microphone, volume control and a wired USB-C connection that will not drop out.
• Best for adjustable fit across ages → ProCase Noise Cancelling Headphones. Telescopic arms stretch about 1.3 inch per side and the cups rotate 360°.
• Best for plugging into a laptop or USB-C phone → Cowyawn USB C Headphones. No adapter, no pairing, no charging.
• Best for sensory needs and autism → ProCase Noise Cancelling Headphones. Reduced sensory overload, soft cushions and a hair-safe pivot.
• Best for listening to music, podcasts or video → Cowyawn USB C Headphones. 40 mm dynamic drivers, 32 ohm, 20 KHz — ProCase has no audio at all.
• Best for loud events like fireworks, air shows or monster jam → ProCase Noise Cancelling Headphones. Cowyawn's passive on-ear isolation will not come close.
• Best for families with multiple kids → ProCase Noise Cancelling Headphones. It ships as a 2-pack, so there is a pair for each child.
In my opinion, the right answer depends entirely on what you are trying to solve, so I will not pretend one wins outright. If your problem is noise — a child who melts down at fireworks, an air show, a stadium, or a long flight — I would buy the ProCase earmuffs. Certified isolation, a genuinely adjustable headband and a two-pack make them the only one of these two that actually protects hearing. If your problem is hearing other people, I would buy the Cowyawn headset instead: USB-C, a mic and volume control on the cup, and drivers that can actually play music. Buy the tool that matches the job.
how to adjust headphones
On the ProCase earmuffs, pull the telescopic arms outward — each side extends up to about 32 mm (1.3 inch) — until the cups sit flat over the ears, then rotate the 360° cups to match the angle of the head. On the Cowyawn headset, slide the band to fit and use the on-cup controls for volume. Both are adjustable; ProCase's range is designed specifically to cover different ages of kids.
how to adjust headphones volume
Only the Cowyawn USB C Headphones have volume control — it is handled through the on-earcup controls, which use touch and a button. The ProCase earmuffs have no audio electronics and no volume at all; they only reduce outside noise through physical sound isolation, so there is nothing to turn up or down.
how to adjust headphones sound
Sound adjustment on the Cowyawn headset happens at the source — your phone, laptop or computer — since the headset itself only controls volume. Its 40 mm dynamic drivers, 32 ohm impedance and 20 KHz frequency response mean it plays what the device sends it. The ProCase earmuffs do not produce sound, so there is nothing to tune.
how to adjust headphones on iphone
The Cowyawn headset uses a USB Type C plug, so it connects directly to USB-C iPhones as well as laptops and computers — you would adjust sound through the phone's own controls. The ProCase earmuffs have no connector and no audio, so they are not something you pair or plug into a phone; they simply block noise.
