How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, travel-ready hard shell to protect your Beats on-ear headphones, choose SQERO Case; if you need a kid-safe wired USB-C headphone for school, tablets and travel, choose Bywulanda Upgrade USB Type.
These two products barely overlap. One is a storage case built around Beats Solo 3, Solo 4, Studio Pro and Studio3. The other is a pair of wired USB-C kids headphones with a 94dB volume cap. In my opinion, the right pick comes down to one question: are you protecting headphones you already own, or buying headphones for a child? Below I break down the design, the specs and the real trade-offs of each so you can decide with confidence.
• SQERO Case — biggest strength: a dual-layer EVA hard shell (frosted outer finish, soft padded lining) custom-sized for Beats Solo 3, Solo 4, Studio Pro and Studio3, with room left over for cables and small accessories.
• SQERO Case — biggest trade-off: it protects headphones, it is not headphones. If you do not own one of those four Beats models, it is the wrong purchase.
• Bywulanda Upgrade USB Type — biggest strength: a 94dB safe volume limit plus a native USB-C plug (no converter), 40mm dynamic drivers and a foldable, adjustable build for kids and teens.
• Bywulanda Upgrade USB Type — biggest trade-off: it is wired USB-C only. There is no Bluetooth, so it needs a device with a Type-C jack.
• Buy the SQERO Case if you already own Beats Solo 3, Solo 4, Studio Pro or Studio3 and want a shockproof travel home for them.
• Buy the Bywulanda Upgrade USB Type if you are outfitting a child or student with safe, plug-and-play headphones for school, a tablet or a trip.
The SQERO Case is a purpose-built storage shell, and its dimensions tell you exactly how serious that purpose is: 7.48in × 4.72in × 3.34in, sized specifically for Beats Solo 3, Solo 4, Studio Pro and Studio3 wireless headphones. That is not a generic pouch that happens to fit. It is a molded shape, which matters because a loose case lets headphones rattle, and rattling is how hinges and headbands get stressed in a backpack.
The protection story is the dual-layer build. The outer shell is EVA — waterproof and impact-resistant — while the inner lining is soft and padded. That combination is the sensible one for travel: a hard, water-resistant exterior handles the knocks of a commute, a plane overhead bin or the bottom of a school bag, and the padded interior keeps the finish from getting scuffed. The manufacturer also lists shockproof as an additional feature and rates the water resistance level as water resistant, which is what you want for rain, spills and general damp rather than full submersion.
Capacity is the part people underestimate. Beyond holding the headphones themselves, the case is designed to take headphone cables, charging cables and a USB dongle or two. Small volume, considerable capacity, as the listing puts it — and for a traveler that is the difference between one tidy bundle and a tangle at the bottom of a bag. The frosted shell texture and smooth lines give it a clean, modern look, so it does not read as a utilitarian brick.
Who should buy it: anyone who owns one of those four Beats models and moves them around — commuters, students, frequent flyers, or anyone who has ever pulled a headphone out of a bag and found the earcup scratched. Who should skip it: anyone with a different headphone brand or model, and anyone looking for audio gear rather than storage. In my opinion this is a "buy it once, stop worrying" accessory, not a gadget. If you want to know what it costs today, check the current price on Amazon.
The Bywulanda Upgrade USB Type is aimed at a completely different buyer: a parent, grandparent or teacher shopping for a child. The headline feature is the 94dB safe volume limit. That number is the whole point of the product. Kids do not naturally modulate volume, and a hard ceiling at 94dB means the headphones cannot be cranked to painful levels no matter how enthusiastically the volume control is pushed. It is the kind of design decision that gives parents peace of mind rather than another thing to monitor.
The second practical win is the connector. This is a native USB-C plug — no adapter, no dongle, no "where did the converter go" drama. It works with smartphones and tablets that have a Type-C jack, which today covers a huge share of the devices kids actually use for schoolwork and streaming. Plug it in and it works. That simplicity is worth more than it sounds when the user is eight years old.
On the audio side, Bywulanda specifies 40mm dynamic drivers covering a 20Hz–20,000Hz frequency range with 30 ohm impedance. In plain terms: a full-size driver for an on-ear headphone, a frequency range that spans the audible spectrum, and an impedance low enough that a phone or tablet drives it without trouble. The earpieces are on-ear with an over-ear shape, and the fit is adjustable — the headband expands from small kids up to teenagers, which means the same pair can survive a growth spurt or be handed down between siblings. The unit weighs 0.18 kg, light enough that it is not a burden on a small head.
Who should buy it: parents of younger children, students who need a reliable wired pair for a Type-C tablet or phone, and anyone who wants volume protection built in rather than hoped for. Who should skip it: anyone who needs wireless audio, and anyone with a device that only has a 3.5mm jack — this is a USB-C headphone, not a universal one.
Side-by-Side: Which Should You Choose?
• Best for protecting existing Beats headphones → SQERO Case. It is custom-sized for Solo 3, Solo 4, Studio Pro and Studio3 at 7.48in × 4.72in × 3.34in.
• Best for child hearing safety → Bywulanda Upgrade USB Type. The 94dB volume limit is the single most important spec on the sheet.
• Best for travel with accessories → SQERO Case. The EVA waterproof, impact-resistant shell plus room for cables and a USB dongle keeps everything in one place.
• Best for plug-and-play on tablets and phones → Bywulanda Upgrade USB Type. Native USB-C, no converter required.
• Best for growing kids → Bywulanda Upgrade USB Type. The adjustable headband expands from kids to teens, and the foldable design saves bag space.
• Best for a commute or gym-bag scenario → SQERO Case. Shockproof, water-resistant and padded is built for the bottom of a bag.
• Best for shared family use → Bywulanda Upgrade USB Type. Light (0.18 kg), volume-capped and backed by a stated 2-year warranty.
• Skip the SQERO Case if your headphones are not Beats Solo 3, Solo 4, Studio Pro or Studio3. Skip the Bywulanda if you need wireless or your device has no Type-C jack.
If I were buying for myself and I already owned Beats Solo 3, Solo 4, Studio Pro or Studio3, I would buy the SQERO Case. The custom dimensions, the EVA waterproof and impact-resistant shell and the padded interior solve a specific, annoying problem, and the extra room for cables makes it more useful than a plain pouch. If I were buying for a child, I would buy the Bywulanda Upgrade USB Type without much hesitation — the 94dB limit, the native USB-C plug and the adjustable, foldable build are exactly the right priorities for that buyer. They are not competitors so much as answers to two different questions. Pick the one that matches your question.
Yes. The case is custom-sized for Beats Solo 3, Solo 4, Studio Pro and Studio3 wireless headphones, with listed dimensions of 7.48in × 4.72in × 3.34in. If your headphones are a different brand or model, this case is not designed for them.
No. They use a native USB-C plug, so there is no converter or dongle involved — you plug them straight into a Type-C phone or tablet. They are wired only, so there is no Bluetooth pairing to worry about either.
They are capped at 94dB, which is the safety feature rather than a limitation to work around. The 40mm dynamic drivers cover 20Hz–20,000Hz, so music, movies and school audio come through clearly within that safe range.
I do not quote prices here because they change. Value depends on your need: the SQERO Case is worth it if you own one of the four Beats models it fits, and the Bywulanda is worth it if you need safe, wired USB-C headphones for a child. Check the current price on Amazon before deciding.
