• New Bee Kids Headphones — biggest strength: A true all-in-one on-ear headphone with a built-in HD microphone, a wired 3.5 mm connection, and switchable 85dB/94dB volume limiting for kids roughly 4–16.
• New Bee Kids Headphones — biggest trade-off: It's wired only, and it doesn't come with its own carry case (the listing describes a black carrying case color, but the case itself isn't a separate hard shell).
• ZUJFPL EVA Hard Case — biggest strength: A purpose-built EVA/Nylon hard shell with dust, shock and water-repellent protection, sized specifically for Beats Solo2, Solo3 and Beats Studio Pro on-ear headphones.
• ZUJFPL EVA Hard Case — biggest trade-off: It's a case, not headphones — it protects but doesn't play, and it doesn't fit every on-ear model on the market.
• Who each is for: Buy New Bee if you need working headphones for a child; buy ZUJFPL if you already own compatible Beats and want to keep them safe on the move.
New Bee's KH20 is designed from the ground up as a child's first real headphone. The headline feature is the volume limiter: you can cap output at 85dB or step up to 94dB, which lets you keep everyday listening quiet while still giving a little more headroom for noisy environments like a car, a bus or a classroom. For parents, that single switch is the whole point — it's a hardware ceiling rather than something a kid can override by mashing a volume button.
It's a wired on-ear model with a 3.5 mm jack, a built-in HD microphone, and a rounded, swivel-mounted leatherette cushion design over a stainless-steel slider. The foldable, adjustable build matters more than it sounds: on-ear headphones with a stainless slider hold their fit over time, and the swivel mounts let the cups lie flat, which is exactly what you want when they get tossed into a school bag. The 32-ohm, dynamic drivers covering 20 Hz–20,000 Hz are a standard, undemanding spec that any phone, tablet, Kindle, PC or Mac with a 3.5 mm port can drive without help. The built-in mic means it doubles as a headset for remote classes and games.
Who should buy it: parents of kids roughly 4–16 who need one reliable headphone for school, tablets, gaming and travel, and who care most about volume safety. Who should skip it: anyone whose device is a lightning-only iPhone 7 or newer or an iPad Pro 11/12.9 (2020) without an adapter — you'd need a lightning-to-3.5 mm adapter, and you should confirm your port before ordering. Also skip it if your child insists on wireless, since this is a wired set despite the Bluetooth field in the spec sheet.
The ZUJFPL EVA Hard Case is a single-purpose accessory: a moulded hard shell for Beats Solo2, Solo3 and Beats Studio Pro on-ear headphones. The outer dimensions — 7.7 in long, 6.1 in wide, 3.5 in high — are built around that specific family of headphones, so the fit is deliberate rather than universal. Inside, the lid has an independent grid compartment for cables and chargers, which is the detail that separates a real travel case from a cloth pouch: your cable doesn't end up scratching the ear cups.
The material story is straightforward. The EVA shell is shockproof, dustproof and semi-waterproof (the spec sheet lists the water resistance level as water repellent), so it shrugs off rain, splashes, dust and the general knocks of a backpack or a suitcase. There's a carry handle for hand-carrying, and it slips into luggage easily. Grey exterior, nylon finish — understated and practical rather than flashy.
Who should buy it: adults who already own Beats Solo2, Solo3 or Beats Studio Pro and want them protected in transit. Who should skip it: anyone who doesn't own one of those exact models — the fit is specific, and a case that's too big or too small defeats the purpose — and anyone shopping for headphones rather than storage, because the case comes empty (the headphones are not included).
• Best for volume safety for kids → New Bee Kids Headphones, with its switchable 85dB/94dB limiter.
• Best for protecting headphones you already own → ZUJFPL EVA Hard Case, with its shockproof, dustproof, water-repellent EVA shell.
• Best for calls, online classes and gaming chat → New Bee Kids Headphones, thanks to the built-in HD microphone.
• Best for travel and commuting durability → ZUJFPL EVA Hard Case, which is designed specifically for the bumps of bags, suitcases and outdoor use.
• Best for device compatibility breadth → New Bee Kids Headphones, which works with any 3.5 mm audio jack device (with an adapter for lightning-only Apple gear).
• Best if you own Beats Solo2, Solo3 or Beats Studio Pro → ZUJFPL EVA Hard Case, since it's sized for exactly those models.
• Best one-item purchase for a child → New Bee Kids Headphones, because it's a complete, ready-to-use headset.
• Best add-on purchase → ZUJFPL EVA Hard Case, an accessory rather than a primary buy.
In my opinion, the right pick comes down to what's missing from your setup. If you're buying for a kid and need headphones that work today — safe volume, a mic for class, a wired connection that just plugs in — I'd buy the New Bee Kids Headphones. If you already own compatible Beats and your problem is a cracked or scuffed pair after one too many trips, I'd buy the ZUJFPL EVA Hard Case instead. They're not really competitors; they solve two different problems. Check the current price on Amazon, since both are inexpensive accessories where the value math is easy to run yourself.
what are the best open ear headphones
That depends on whether you mean on-ear or truly open designs. In this comparison, the New Bee KH20 is an on-ear model with 32-ohm dynamic drivers and a 20 Hz–20,000 Hz range, so it's the one that actually plays audio. The ZUJFPL EVA Hard Case isn't a headphone at all — it's storage for Beats Solo2, Solo3 and Beats Studio Pro.
are on ear headphones good
On-ear headphones like the New Bee KH20 rest on the ear rather than around it, which makes them lighter and easier to fold away — useful for kids and travel. The trade-off is less isolation than over-ear designs, though New Bee's set uses sound isolation and a soft, padded leatherette cushion to help.
are open ear headphones good
Open and on-ear designs trade passive isolation for comfort and portability. The New Bee KH20 leans into that with swivel-mounted cups, an adjustable stainless-steel slider and a foldable frame, so it stays comfortable over long school or gaming sessions even without a tight seal.
what are the best in-ear headphones
This comparison doesn't cover in-ear models — the New Bee KH20 is explicitly an on-ear headphone, and the ZUJFPL EVA Hard Case is a carrying case. If in-ear is your priority, neither of these fits that category; pick based on the on-ear and storage needs described above instead.
