If you want to protect a pair of E7-series over-ear headphones you already own, choose Hermitshell Hard Travel Case; if you need a complete kids' wireless headphone with volume limits and long battery life, choose INFURTURE Active Noise Cancelling.
• Hermitshell's biggest strength: A molded EVA hard shell that fits Silensys E7, PurelySound E7, MOVSSOU E7, COWIN E7, Tapela E7 and Audonia E7 headphones, with a water-resistant exterior and a listed weight of just over seven ounces.
• Hermitshell's biggest trade-off: It is a case only. There are no headphones, no cable, no accessories inside the box, so it does nothing for you unless you already own one of those E7 models.
• INFURTURE's biggest strength: A full wireless headphone built for kids, with 85/94dB volume limiting, Bluetooth 5.3, active noise cancellation and a claimed 90 hours of normal playback on one charge.
• INFURTURE's biggest trade-off: It is a child-focused product with a stretchable headband and a 16-ohm dynamic driver, so it is not aimed at adult listeners chasing critical sound quality.
• Who Hermitshell is for: Anyone who owns (or is about to own) an E7-series headphone and wants a hard shell instead of a soft pouch.
• Who INFURTURE is for: Parents buying a first real pair of wireless headphones for a kid, especially for flights, trains and car rides.
The Hermitshell case is a single-purpose object, and it is honest about that. It is a hard EVA shell with an inner size of 7.6 by 7.4 inches, and it is explicitly cut to fit the E7 family of active noise cancelling Bluetooth headphones — Silensys, PurelySound, MOVSSOU, COWIN, Tapela and Audonia. If your headphones match that list, the fit question is essentially answered for you. If they don't, this isn't your case.
What it does best is absorb the kind of abuse a backpack dishes out. Bumps, dents, scratches — the material and the rigid form factor are the whole point. The EVA enclosure is listed as water resistant, which matters more than people expect when a bag sits on a wet floor or gets caught in a drizzle. The solid purple finish and the "Music" theme styling are cosmetic, but they make the case easy to spot at the bottom of a bag, which is a small thing that adds up on travel days.
Who should buy it: anyone who has already committed to one of those E7 headphones and treats them as a piece of gear rather than a disposable. Students, commuters, frequent flyers, parents packing a bag the night before a trip. At 7.04 ounces the case adds very little heft, so there is no real penalty for carrying it.
Who should skip it: anyone who hasn't bought the headphones yet, and anyone expecting anything other than the case itself. The listing is upfront that this is case only — the device and accessories are sold separately. If you want a soft drawstring pouch instead of a rigid shell, or if your headphones are not on the compatibility list, look elsewhere. In my opinion, this is the right pick specifically for the person who already has the headphones and now wants to stop replacing them.
INFURTURE's headphone is designed around one word: kids. The headband is stretchable to fit toddler head sizes, the ear pads are ultra-soft protein leather over memory foam, and the ear placement is over-ear with an oval earpiece shape. That combination is aimed at long wear sessions — the kind where a child leaves them on through a three-hour flight and then forgets to take them off in the car.
The safety feature is the headline. Volume is limited to 85/94dB, and the product notes CE-certified volume-limiting technology. For a parent, that is the spec that actually matters, because it is the one thing you cannot fix later with better habits. The 16-ohm impedance and 20 Hz–20,000 Hz dynamic driver tell you this is tuned for general listening — music, audiobooks, movies — rather than audiophile work, which is exactly right for the audience.
Then there is battery. INFURTURE lists 50 hours with ANC on and 90 hours of normal playtime, with an average battery life figure of 70 hours. Either way you read it, that is a device that survives a multi-day trip without a charger hunt. Bluetooth 5.3 with a 10-meter range covers the normal distance between a kid in a seat and a parent's phone on the tray table. There's also a 3.5 mm jack and a cable included, so it works wired when Bluetooth isn't an option — a genuinely useful fallback on planes with seatback entertainment.
Active noise cancellation is handled with push-button controls rather than touch, which I think is the better call for this age group: physical buttons give feedback you can feel, and they don't misfire when small hands brush against them.
Who should buy it: parents and gift-buyers shopping for a child, teen or young traveler. The foldable design and the airplane/train/car framing make the intended use obvious. Who should skip it: adult listeners who want a neutral, detailed sound signature, and anyone who wants a small in-ear solution rather than over-ear. It's also worth noting it ships as one item with a cable and user manual, and carries a two-year warranty description.
• Best if you already own E7-series headphones → Hermitshell Hard Travel Case. It exists to protect a specific set of models and does nothing else.
• Best if you need working headphones out of the box → INFURTURE Active Noise Cancelling. The Hermitshell box contains no audio gear at all.
• Best for battery life → INFURTURE. 90 hours of normal playtime, 50 with ANC engaged, against a case that has no electronics.
• Best for hearing safety with kids → INFURTURE. The 85/94dB volume limit is the deciding feature for a child listener.
• Best for physical durability of your gear → Hermitshell. EVA hard shell, water-resistant, built to take bumps and dents.
• Best for travel packing → Depends on the job. Hermitshell keeps headphones safe in a bag; INFURTURE folds down and entertains a kid for the whole journey.
• Best for wired fallback → INFURTURE. A 3.5 mm jack plus an included cable means it works without Bluetooth.
• Best for a gift → INFURTURE. A case is a practical add-on; a headphone is the actual present.
If you put a gun to my head and made me pick one, I'd buy the INFURTURE Active Noise Cancelling headphones — but only because most people searching these two names together are shopping for a listener, not for storage. It is a complete product with a real safety feature, a long battery, Bluetooth 5.3 and a wired backup, and it works the moment it comes out of the box.
That said, I'd recommend the Hermitshell case without hesitation to a narrower group: someone who already owns a Silensys, PurelySound, MOVSSOU, COWIN, Tapela or Audonia E7 headphone and is tired of replacing them. If that's you, the case is the smarter buy. If you're buying for a kid, the INFURTURE is the one I'd put in the cart.
Either way, check the current price on Amazon before you commit — the button on this page will take you there — and confirm the compatibility list or the age range matches your situation.
FAQ
The data sheet lists active noise cancellation with push-button controls, and claims 50 hours of playtime with ANC on. That is a real ANC system, though it is tuned for minimizing background noise on planes, trains and car rides rather than for studio-grade isolation.
The age range covers kid, teen and adult, and the over-ear memory foam pads suit most head sizes. But the design — stretchable headband, 85/94dB limiting, 16-ohm driver — is clearly built around younger listeners.
They solve different problems, so value depends on what you're missing. If you need a working headphone, the INFURTURE gives you far more for your money. If you only need protection for headphones you already own, the Hermitshell is the cheaper, more focused answer. Compare current prices on Amazon for both before deciding.
