If you want a protective hard shell that keeps a pair of over-ear noise-cancelling headphones safe when they travel, choose Hermitshell Hard Travel Case; if you need to shield a baby's ears from loud environments, choose funbliss Baby Ear Protection. That is the whole decision in one line — one is storage, the other is hearing protection. Neither is a substitute for the other, and if you are shopping for headphones that actually fit a big head, neither of these is the headphone itself; they are the accessories around it.
• Hermitshell's biggest strength: a molded EVA shell with water-resistant, heavy-duty protection built specifically around the E7 family of over-ear headphones, in a purple finish that is easy to spot in a bag.
• Hermitshell's biggest trade-off: it is a case only. The headphones and accessories are sold separately, and it fits a defined list of models rather than "any headphones."
• funbliss's biggest strength: a 25dB noise reduction rating in a clip-on design that avoids forehead and head-back pressure, sized for babies 3–36 months.
• funbliss's biggest trade-off: it is age-limited by design. This is not something an adult or an older child wears, and it is hand wash only.
• Who Hermitshell is for: anyone who already owns (or is buying) Silensys, PurelySound, MOVSSOU, COWIN, Tapela or Audonia E7 headphones and wants them to survive a commute, a flight or a backpack.
• Who funbliss is for: parents flying, traveling, or heading to fireworks, concerts and sporting events with an infant or toddler.
Think of the Hermitshell case as armor for one specific family of headphones. The shell is ethylene vinyl acetate — EVA — which is the same class of semi-rigid foam material used in a lot of molded travel cases. It holds its shape, so the pressure of a packed carry-on or a jammed backpack lands on the case instead of on the headband and ear cups. Hermitshell lists the job plainly: protect the device from bumps, dents and scratches, and the water-resistant rating adds a layer of insurance against a spilled drink or a rain-soaked bag.
The compatibility list is the part to read carefully. It is made to fit the E7 line across Silensys, PurelySound, MOVSSOU, COWIN, Tapela and Audonia. The interior is listed at 7.6 by 7.4 inches, which is roomy for a folded pair of over-ear cans but still a defined footprint — this is not a "fits everything" pouch. It weighs about 7.04 ounces, light enough that it adds almost nothing to a bag, and the purple color is a genuinely useful detail if you have ever dug through a black-lined backpack looking for a black case. The solid, music-themed styling is understated, which suits a product whose whole job is to disappear into your luggage until you need it.
funbliss Baby Ear Protection: Who It's For
The funbliss earmuffs solve a completely different problem: a baby's hearing is delicate, and long or repeated exposure to loud sound can cause real damage. Funbliss puts a 25dB noise reduction rating on these, and that number is the headline. It will not silence a jet engine or a stadium, but it takes the edge off the loudest environments — which is exactly what a parent needs on a flight, at a fireworks show, at a concert or at a sporting event.
The design choice I find most interesting is the clip-on fit. Funbliss reasons that most babies dislike pressure on the forehead and the back of the head, so they tug at anything that grips those spots. Instead, the earmuffs clip on with no pressure to the head circumference. That is a smart bit of practical thinking, because an earmuff a baby refuses to wear protects nothing. The cups use professional noise-cancelling sponges, and the frame is acrylonitrile butadiene styrene — ABS plastic — a common, tough material for lightweight gear. At 6.4 ounces, it is light enough that a small child is not fighting the weight, and the adjustable fit is designed to grow with the child from infancy through the toddler years.
It is sized for ages 3–36 months, unisex, and it folds down with an included storage bag, which matters more than it sounds — baby travel gear lives or dies on whether it packs flat. One practical note: care instructions say hand wash only, so plan on wiping the ear cups rather than throwing them in with the laundry. Who should buy it: parents of a baby or toddler with a flight, a road trip, a wedding, a parade or a fireworks night on the calendar. Who should skip it: anyone shopping for an adult or an older child, and anyone expecting these to double as everyday headphones — they are protection, not audio gear.
• Best for protecting an actual pair of headphones → Hermitshell Hard Travel Case.
• Best for protecting a baby's hearing → funbliss Baby Ear Protection.
• Best if you own Silensys, PurelySound, MOVSSOU, COWIN, Tapela or Audonia E7 headphones → Hermitshell, since the fit is built around that exact list.
• Best if you are flying with an infant or toddler → funbliss, thanks to the 25dB rating, the foldable frame and the included storage bag.
• Best for a baby who rips headbands off → funbliss, because the clip-on design avoids forehead and head-back pressure.
• Best for a no-fuss, toss-it-in-the-bag item → Hermitshell, at roughly 7 ounces with a water-resistant EVA shell.
• Best for someone who wants gear that grows with the user → funbliss, with its adjustable fit across the 3–36 month range.
• Best for a shopper torn between the two → decide which problem is actually on your list this month. A cracked headphone and a crying baby on a plane are not the same emergency.
In my opinion, these two should not really be competing — but if I had to pick one for the "big head" shopper, I would buy the Hermitshell Hard Travel Case. Here is my reasoning: the E7-style over-ear headphones it is built for are exactly the kind of large, roomy cans people reach for when they are hunting the best over ear headphones for big head, and once you have found a pair that fits, you want it to survive the trip. The case is the cheap insurance on an expensive fit. The funbliss earmuffs are excellent at what they do, and I would recommend them without hesitation to any parent traveling with a baby — but they are a different purchase for a different person. Buy the case for your headphones; buy the earmuffs for your kid.
Only if they are on the listed E7 family — Silensys, PurelySound, MOVSSOU, COWIN, Tapela or Audonia. The interior is listed at 7.6 by 7.4 inches, so check your folded headphone dimensions against that before ordering. If your model is not on the list, this case is a gamble.
It means the earmuffs reduce incoming sound by roughly 25 decibels, which takes a loud environment down to something much more tolerable. It does not make a concert silent or replace distance from the speakers. For flights, fireworks and stadiums, that reduction is the difference between a startled baby and a sleeping one.
Do the funbliss earmuffs work for adults or older kids?
No. They are designed for ages 3–36 months, and the clip-on fit is built around a small head circumference. For an adult, these would be the wrong product entirely — an adult looking for quiet needs actual headphones, and someone with a larger head should be looking at the best over ear headphones for big head or the best bone conduction headphones for big head instead.

Value depends on your need: if you already own E7 headphones, the case protects a purchase you have made. If you have a baby and a flight booked, the earmuffs protect something you cannot replace.
