How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a hard shell tailored specifically to Beats Solo3 and Solo4 on-ear headphones, choose Yinke Case; if you need a slim, kid-friendly carrying case for JBL Junior or Sony on-ear headphones, choose XANAD Hard Case. Both are EVA hard shells with soft interiors and zippered closures — the real difference is which headphones they're built around and how they're meant to travel.
• Yinke Case — biggest strength: A dual-layer EVA shell with a waterproof, impact-resistant exterior and a soft padded lining, custom-dimensioned for Beats Solo3 and Solo4 only.
• Yinke Case — biggest trade-off: Narrow compatibility. It is explicitly not designed to fit other headphone models, so it's a poor choice if your headphones aren't Beats Solo3 or Solo4.
• XANAD Hard Case — biggest strength: Broad fit across several JBL Junior and Sony MDR on-ear models, with a full mesh pocket in the lid for cables and adapters.
• XANAD Hard Case — biggest trade-off: It's built for kids' and compact on-ear headphones, so it's not intended for larger or differently shaped models.
• Who each pick is for: Yinke suits adult Beats Solo owners who want a snug, protective travel shell; XANAD suits parents and students carrying JBL Junior or Sony on-ear headphones.
The Yinke Case is a purpose-built storage shell for Beats Solo3 and Beats Solo4 wireless on-ear headphones. That specificity is the whole point. The interior is dimensioned around those two models, so the fit is snug rather than generic — the headphones sit where they're supposed to instead of sliding around inside a one-size box. Yinke states plainly that it does not fit other headphone models, so this is a case you buy because you already own the right headphones, not because you hope it will work.
The construction is where it earns its keep. The outer shell is EVA — the same waterproof, impact-resistant foam material used across this category — and the interior is soft and padded. That combination matters for real trips: a tough outer layer shrugs off the knocks of a packed bag, while the padded lining keeps the headphone surfaces from scuffing against the shell. Yinke also leans into small design touches — a smooth fabric top and frosted fabric bottom for grip, a dot-patterned bottom lining, and a portable strap for carrying.
Who should skip it: anyone with a different headphone model. Because compatibility is restricted to Beats Solo3 and Solo4, this is not a general-purpose case, and buying it for anything else is asking for a loose or unusable fit.
XANAD Hard Case: Who It's For
The XANAD Hard Case solves a different problem: it's designed for the smaller, folding headphones that kids and students actually carry. It fits the JBL Junior JR 320 and 320BT, the JR310BT, and Sony's MDR-ZX110, MDR-ZX110NC and MDR-ZX310AP on-ear models. XANAD also lists compatibility with a range of other foldable kids' headphones, including iClever, Candy Bila, MIDOLA, noot Products, EarFun and IMYB models — so if you're shopping for a child's headset rather than a specific audiophile pair, the odds of a fit are genuinely good.
Protection is the expected EVA package: a hard, waterproof, shockproof shell that shields against bumps, drops, scratches and dust. The exterior is wrapped in an oxford fabric that XANAD says resists scuffs and light water splashes. That's meaningful for the way kids treat gear — tossed into a school bag, dropped on a bus, stuffed in a suitcase. The 360-degree zipper is described as smooth but strong, which matters when small hands are opening and closing it every day.
The interior detail I like most is the full mesh pocket in the lid. It's the right place for charging cables, adapters and small accessories, and it keeps them from rattling against the headphones. The slim profile and durable hand strap make it easy to carry by hand or slide into a backpack or suitcase, and it comes in a range of colors that adds a bit of personality. XANAD also positions it as a gift — for a friend, family member or student — which fits the kid-focused design.
Who should skip it: anyone with full-size over-ear headphones or Beats Solo models. This case is built around compact, foldable on-ear designs, so it isn't the right shell for larger gear.
• Best for Beats Solo3 or Solo4 → Yinke Case. It's custom-dimensioned for those two models specifically.
• Best for JBL Junior or Sony MDR on-ear headphones → XANAD Hard Case. It covers JR 320, 320BT, JR310BT, MDR-ZX110, MDR-ZX110NC and MDR-ZX310AP.
• Best for kids and students → XANAD Hard Case. The slim profile, hand strap and easy 360-degree zipper are built for school bags and small hands.
• Best for adult commuters and travelers → Yinke Case. The grip-friendly fabric top and bottom, dot-padded lining and portable strap read as a grown-up travel accessory.
• Best for organizing small accessories → XANAD Hard Case. The lid's full mesh pocket is purpose-made for cables and adapters.
• Best for accessory capacity inside the main compartment → Yinke Case. It's designed to hold headphone cables, charging cables and USB items alongside the headphones.
• Best for broad headphone compatibility → XANAD Hard Case. It lists far more compatible models than Yinke's single-family fit.
• Best if you own anything other than Beats Solo3/Solo4 → XANAD Hard Case. Yinke's fit is intentionally narrow and won't suit other headphones.
If I owned Beats Solo3 or Solo4 headphones, I'd buy the Yinke Case. The custom interior, the waterproof EVA shell, the padded lining and the accessory room all line up with how I'd actually carry a pair of Solo headphones — snug, protected, and easy to grab. If I were buying for a kid with JBL Junior or Sony on-ear headphones, I'd buy the XANAD Hard Case instead, because the fit, the mesh pocket and the slim, strap-ready design are built for exactly that job. In my opinion, this isn't a case of one being better than the other — it's a case of matching the shell to the headphones you already own. Buy for the model, not the brand. And since pricing shifts, check the current price on Amazon before you commit.
Yes. Yinke states the case is dimensioned for both Beats Solo3 and Beats Solo4 wireless headphones. It is explicitly not designed to fit other headphone models, so confirm your model before buying.
It's designed to fit JBL Junior JR 320, 320BT and JR310BT, plus Sony MDR-ZX110, MDR-ZX110NC and MDR-ZX310AP. XANAD also lists several other foldable kids' headphone brands as compatible.
Both use an EVA hard shell that's described as waterproof, shockproof and impact-resistant, with a soft interior lining. Durability is comparable in materials terms; the bigger difference is fit, since a snug case protects better than a loose one.
The Yinke Case is the better fit for adult travel with Beats Solo3/Solo4, thanks to its padded compartment and room for cables. The XANAD Hard Case is the better travel pick for kids' on-ear headphones, with its slim profile, hand strap and mesh accessory pocket.
No. Both are cases only — the headphones are not included with either product.
