These two products only look like rivals until you read the spec sheets. One is a storage case with no electronics inside it at all. The other is a pair of Bluetooth headbands with speakers built in. The real question isn't which is "better" — it's which job you're actually trying to solve. Here's how I'd split them.
• ZUJFPL EVA Hard Case — biggest strength: a moulded EVA shell sized specifically for Beats Solo2, Solo3 and Beats Studio Pro, with a separate mesh pocket for cables and chargers.
• ZUJFPL EVA Hard Case — biggest trade-off: it's a case, not a product with sound. If you don't already own compatible Beats headphones, there's nothing here for you to listen to.
• Perytong 2 — biggest strength: a 2-pack of Bluetooth 5.4 sleep headbands with 40mm removable speakers, up to 14 hours of playtime and machine-washable spandex/nylon fabric.
• Perytong 2 — biggest trade-off: it's built for comfort and sleep, not for critical listening. Sound isolation comes from the fabric sitting over your ears, not from active noise cancelling.
• Who ZUJFPL is for: Beats owners who want their headphones to survive a backpack, a carry-on or a car boot without scuffs and dust.
• Who Perytong 2 is for: side sleepers, joggers, yoga regulars and shift workers who want audio without earbuds pressing into their ears.
Strip away the marketing language and the ZUJFPL case is a simple, honest object: a semi-waterproof EVA shell measuring 7.7 inches long, 6.1 inches wide and 3.5 inches high, moulded around the exact footprint of Beats Solo2, Solo3 and Beats Studio Pro headphones. EVA — ethylene vinyl acetate — is the same closed-cell foam family used in a lot of camera and drone cases, and that's the appeal here. It's stiff enough to take a knock, light enough to forget about, and it shrugs off dust and light moisture rather than soaking it up. The listing describes it as shockproof, dustproof and water resistant, and for a case in this category those are the right claims to make.
Who should buy it: anyone who owns Beats Solo2, Solo3 or Beats Studio Pro and currently tosses them naked into a bag. Students commuting, frequent flyers, parents packing for a trip. Who should skip it: anyone who doesn't own those specific headphones, and anyone expecting the case to include the headphones — it doesn't, and the listing says so plainly. Also skip it if you want something that plays music. This is protection, full stop.
Perytong 2: Who It's For
Perytong 2 is a genuinely different animal, and the spec sheet makes that clear in the first line: it's a 2-pack. You get two sleep headbands, both Bluetooth 5.4, both with 40mm dynamic drivers covering a 20Hz–20,000Hz range and a wireless range of about 43 feet. That 2-pack structure is the whole pitch. One lives on your bedside table, one lives in your gym bag. Or one is the main and one is the spare when the first is in the wash — which matters, because these are made to be washed.
And that's the feature I'd point at first. The fabric is a spandex and nylon blend chosen for moisture wicking and breathability, and the speakers are removable flat 40mm units. Pull them out, throw the headband in the machine, and you've dealt with sweat, oils and whatever else a night's sleep leaves behind. Anyone who has worn earbuds for eight hours knows how quickly that becomes a problem. Perytong solves it with a laundry cycle rather than a cleaning ritual.
Battery is the other headline. Up to 14 hours of continuous playback, with a roughly 1-hour charge time over Type-C. That's a full night's sleep with room left over, and it means the headbands can cover a night plus a day of on-and-off use before they need topping up. For shift workers, overnight travellers or anyone whose schedule doesn't line up with a charging routine, that's the number that actually matters. Bluetooth 5.4 also handles the connection side — a stable link for ASMR, podcasts, white noise or music, without the dropouts that make sleep audio useless.
The three-in-one framing is accurate, too. Pull the band up over your ears for a run and it's a sport headband. Wear it normally in bed and it's side-sleeper-friendly audio, because there's no hard plastic pressing into your ear against the pillow. Slide it down over your eyes and it does a passable sleep mask impression. Controls are touch-based, and there's a 2-year manufacturer warranty on the pair.
Who should buy it: side sleepers who can't tolerate earbuds, runners and yoga regulars who want sweat-resistant audio, and anyone who wants one product instead of three. Who should skip it: people who care about fidelity first. The drivers are 40mm dynamic units in a fabric band, and the noise control is sound isolation rather than active cancellation — so on a plane or a train, don't expect silence, expect your audio sitting on top of the noise.
• Best for protecting Beats Solo2/Solo3/Studio Pro → ZUJFPL EVA Hard Case. The dimensions are matched to those models specifically.
• Best for actual listening → Perytong 2. ZUJFPL has no audio hardware at all.
• Best for side sleepers → Perytong 2. Fabric over the ear beats hard plastic against a pillow.
• Best for travel durability → ZUJFPL EVA Hard Case. EVA shell, water resistant, shockproof, dedicated cable pocket.
• Best for long sessions → Perytong 2. Up to 14 hours per charge, roughly 1 hour to refill.
• Best for hygiene and repeated daily wear → Perytong 2. Removable speakers, machine-washable spandex/nylon blend.
• Best for a two-person household or a gift → Perytong 2. You're buying two headbands, not one.
• Best if you already own Beats and just need storage → ZUJFPL EVA Hard Case. It's the missing accessory, not a competing product.
In my opinion these aren't really substitutes, so my recommendation splits cleanly. If you own Beats Solo2, Solo3 or Beats Studio Pro and you're currently carrying them loose, I'd buy the ZUJFPL EVA Hard Case — a fitted EVA shell with a cable pocket is exactly what those headphones are missing, and the matched dimensions mean it actually fits rather than "sort of" fits. If instead you want sound in your ears at night or on a run, I'd buy Perytong 2 — two washable Bluetooth 5.4 headbands with 14 hours of playback is the more useful purchase for that job. Check the current price on Amazon for whichever one matches your situation before you commit, since both sit in very different budget brackets.
FAQ
Yes. The listing names Beats Solo2, Beats Solo3 and Beats Studio Pro as the compatible models, and the case is sized at 7.7 x 6.1 x 3.5 inches around that footprint. Headphones are not included.
Up to 14 hours of continuous use per the spec sheet, with a charge time of about 1 hour via Type-C. In practice that covers a full night plus a day of intermittent listening.
Yes — that's the point of the removable 40mm speakers. Detach them, then machine wash the spandex and nylon band to clear out sweat, oils and allergens.
No. It uses sound isolation, meaning the fabric band sitting over your ears blocks some outside noise, but there's no active noise cancellation. For flights or loud commutes, don't expect silence.
They solve different problems, so value depends on what you need. Perytong 2 gives you two working audio devices with a 2-year manufacturer warranty; ZUJFPL gives you one protective case. Check the current price on Amazon for both and judge against your own use case.
