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 case purpose-built for your JBL Tune 500BT, 510BT or 520BT with a true waterproof shell and a carabiner for clipping onto a bag, choose Mchoi Hard; if you need a lightweight hard case for Sony MDR-ZX110, ZX110AP, ZX110NC or ZX310AP wired on-ear headphones with a soft padded interior and a longer warranty, choose YIHAOBOX Case Compatible.
• Mchoi Hard — biggest strength: Hard EVA shell rated waterproof, with a built-in mesh pocket and a carabiner keychain for attaching the case to a purse, backpack or bag.
• Mchoi Hard — biggest trade-off: It's a single-purpose fit for JBL Tune 500BT / 510BT / 520BT only, and the manufacturer lists no warranty.
• YIHAOBOX Case Compatible — biggest strength: A layered interior (anti-static shockproof layer plus fluffy fabric lining) in a lighter case, backed by a 1-year warranty.
• YIHAOBOX Case Compatible — biggest trade-off: Its protection is described as semi-waterproof rather than waterproof, and it's sized for Sony ZX-series wired headphones, not JBL models.
• Who each is for: Mchoi Hard is for JBL Tune owners who want splash-and-drop protection and clip-on portability; YIHAOBOX Case Compatible is for Sony ZX-series owners who want a soft-lined, lighter case with warranty coverage.
Mchoi Hard is a dedicated shell for one family of headphones: the JBL Tune 500BT, 510BT and 520BT on-ear wireless models. That's the whole point of the design. It isn't a universal pouch that "sort of" fits — it's cut for those specific headphones, so the shape holds them in place instead of letting them slide around inside. The case itself is built from hard EVA material, which is the same dense foam-like plastic used in a lot of protective cases, and Mchoi rates the enclosure as waterproof and shockproof. If your headphones live in a backpack that gets rained on, or you toss your bag into a car trunk without thinking about it, that hard shell is doing real work.
Who should buy it: anyone who owns a JBL Tune 500BT, 510BT or 520BT and wants the most protective, most travel-friendly option for exactly that headphone. Who should skip it: anyone with a different headphone model, anyone who needs a warranty (Mchoi lists none), and anyone who wants a plush, fabric-lined interior rather than a hard shell with a mesh pocket.
YIHAOBOX Case Compatible: Who It's For
YIHAOBOX Case Compatible goes the other direction on fit and interior. It's made for Sony's ZX-series wired on-ear headphones — the MDR-ZX110, MDRZX110AP, MDRZX110NC and MDR-ZX310AP. If you own one of those, this case is shaped around them. The outer shell is hard EVA too, but YIHAOBOX describes it as semi-waterproof rather than fully waterproof, which is a meaningful distinction: it handles splashes and light moisture, not a soaking. For most people carrying wired headphones between home, school and an office, that's plenty.
The interior is where this case differentiates itself. There's an extra-soft, anti-static shockproof layer plus a fluffy fabric inner lining. The idea is impact absorption — the soft layers take the hit and the fabric keeps the surface of your headphones from scuffing. YIHAOBOX also lists protection against dust, scratches, scuffs, crush and moisture. It's lighter than the Mchoi at 0.15 kg, and it's described as compact enough to drop into a bag, backpack or luggage. The product information lists it as a "Bag" form factor, and it comes with a 1-year warranty — a real point in its favor if you want some coverage behind the purchase.
Who should buy it: Sony ZX-series wired headphone owners who want a lighter case, a soft padded interior, and warranty coverage. Who should skip it: JBL Tune owners (wrong fit), anyone who needs genuine waterproofing, and anyone who wants an external carabiner or hand strap — those aren't listed here.
• Best fit for JBL Tune 500BT / 510BT / 520BT → Mchoi Hard. It's explicitly designed for those models.
• Best fit for Sony MDR-ZX110 / ZX110AP / ZX110NC / ZX310AP → YIHAOBOX Case Compatible. Same logic, opposite brand.
• Best water resistance → Mchoi Hard. Its sheet says waterproof; YIHAOBOX says semi-waterproof.
• Best interior padding → YIHAOBOX Case Compatible. Anti-static shockproof layer plus fluffy fabric lining.
• Best for clipping onto a bag → Mchoi Hard. Carabiner keychain and hand strap are listed; YIHAOBOX lists neither.
• Lightest to carry → YIHAOBOX Case Compatible. 0.15 kg versus 0.18 kg for the Mchoi.
• Best for storing a cable or small accessory → Mchoi Hard. It has a built-in mesh pocket; YIHAOBOX doesn't list one.
• Best warranty coverage → YIHAOBOX Case Compatible. 1 year, versus no warranty listed for Mchoi.
In my opinion, the deciding factor here isn't quality — it's which headphones you actually own. If you have a JBL Tune 500BT, 510BT or 520BT, I'd buy Mchoi Hard: the waterproof hard shell, mesh pocket, hand strap and carabiner make it the more complete travel case for that headphone, and the no-warranty note is the price of that. If you own a Sony ZX-series wired model, I'd buy YIHAOBOX Case Compatible instead — the soft layered interior and 1-year warranty suit a wired headphone that mostly rides in a bag. Neither is a universal case, so match it to your model and you'll be happy either way.
No. Mchoi Hard is designed specifically for the JBL Tune 500BT, 510BT and 520BT. For Sony MDR-ZX110, ZX110AP, ZX110NC or ZX310AP, the YIHAOBOX case is the matching option.
Not to the same degree. YIHAOBOX describes its EVA shell as semi-waterproof, which handles splashes and moisture. Mchoi rates its case as waterproof. If rain exposure is your main worry, the Mchoi is the stronger pick.
YIHAOBOX Case Compatible is lighter at 0.15 kg versus 0.18 kg for Mchoi Hard. The Mchoi offsets that with a hand strap and carabiner for attaching to a bag, so "easier to carry" depends on whether you want it in your bag or hanging off it.
No. Both are empty cases sold on their own, and any headphones or accessories shown in listing photos are for illustration only. Check the current price on Amazon for each before you decide.
