If you want compact foldable hearing protection built for the shooting range, choose Howard Leight Honeywell Leightning L0F; if you need safe, volume-limited Bluetooth headphones for a child, choose SIMOLIO Kids. These two look like they belong in the same conversation because both fold up small and both are marketed around protecting your hearing. In practice they solve completely different problems for completely different people, and mixing them up is the fastest way to buy the wrong thing.
• Howard Leight Honeywell Leightning L0F — biggest strength: a purpose-built slim earcup with a Noise Reduction Rating of 23 and patented Air Flow Control technology, so it reduces sound across all frequencies without adding bulk.
• Howard Leight Honeywell Leightning L0F — biggest trade-off: it isolates sound rather than playing any. There is no Bluetooth, no microphone, no audio of any kind. It is a hearing protector, not a listening device.
• SIMOLIO Kids — biggest strength: three switchable volume limits at 75/85/94dB plus a share port for two kids to listen to one source, all in a wireless Bluetooth headphone with a 40mm dynamic driver.
• SIMOLIO Kids — biggest trade-off: it is a kids' audio product first. The passive noise cancellation blocks some ambient sound, but it is not a certified hearing protector and won't stand in for range-grade ear protection.
• Who the Howard Leight is for: adult shooters and hunters who want foldable, low-profile protection that won't knock against a gunstock.
• Who the SIMOLIO is for: parents buying a first pair of safe, volume-capped wireless headphones for a toddler through teen.
The Leightning L0F is a folding shooting earmuff, and the folding part is the whole point of the design. It collapses to roughly four inches, which means it drops into a range bag, a jacket pocket or a glovebox without eating space. If you have ever carried a full-size pair of muffs around a range all afternoon, you know how much that matters. The ultraslim earcup is also shaped to stay out of the way of a gunstock, so you can get a proper cheek weld instead of fighting your own gear.
The protection itself comes from the Air Flow Control technology, which the manufacturer describes as reducing sound across all frequencies without enlarging the earcup, backed by a Noise Reduction Rating of 23. In plain terms, NRR 23 is serious attenuation for outdoor and indoor shooting. The trade-off is equally plain: this product makes no sound. There's no Bluetooth, no mic, no cable for audio. Skip it if you want to listen to anything. Buy it if your priority is protecting your ears at the range, on a hunt or around loud equipment, and you want that protection to fold down small.
SIMOLIO Kids: Who It's For
The SIMOLIO Kids headphone is designed around one central worry parents have: how loud is this thing, really? The answer here is a physical switch with three settings. 75dB Quiet Mode suits bedtime stories and kids with sensitive hearing. 85dB Everyday Mode covers homework, tablets and around-the-house use. 94dB Travel Mode is there to push through airplane and bus cabin noise. Because it's a physical switch rather than an app setting, a parent can set it and a child can't quietly dial it back up. That's a genuinely thoughtful piece of design.
The sharing feature is the other standout. There's a built-in share port, so you connect one headphone to a device over Bluetooth and then link a second headphone with the included 3.5mm cable for synchronized audio. No splitter, no dongle. For siblings on a road trip, a classroom listening station or a bedtime story with two kids crowding one tablet, this is the kind of feature that gets used constantly. The 40mm dynamic drivers and the built-in HD mic cover the rest of daily life: online classes, video calls and casual gaming.
Side-by-Side: Which Should You Choose?
• Best for actual hearing protection → Howard Leight Honeywell Leightning L0F. NRR 23 and Air Flow Control are built for gunfire and loud machinery.
• Best for safe listening volume → SIMOLIO Kids. The 75/85/94dB switch is the feature that matters most for young ears.
• Best for folding compactness → Howard Leight Honeywell Leightning L0F. It collapses to about four inches, which is exceptionally small for a protective muff.
• Best for travel with a child → SIMOLIO Kids. The carry case, 15-hour battery and Travel Mode are all aimed at planes, cars and buses.
• Best for two kids sharing one device → SIMOLIO Kids. The share port does what a splitter would, without the extra cable mess.
• Best for long-wear comfort on an adult → Howard Leight Honeywell Leightning L0F. The steel-wire, foam-padded headband and super-soft cushions are tuned to avoid that squeezing sensation.
• Best for calls, classes and gaming → SIMOLIO Kids. The HD mic and Bluetooth 5 make it a two-way audio device, which the Leightning simply is not.
• Best for replacing worn parts instead of the whole product → Howard Leight Honeywell Leightning L0F. The snap-in cushion design lets you refresh the part that wears out.
In my opinion, these aren't really competitors, and that's the honest answer. If your goal is protecting an adult's hearing at the range, I'd buy the Howard Leight Honeywell Leightning L0F — the NRR 23 rating, the slim earcup that clears a gunstock, and the four-inch fold make it the more purposeful tool for that job. If your goal is a safe first wireless headphone for a child, I'd buy the SIMOLIO Kids for the volume limiter switch and the share port alone. Pick by the person and the job, not by the category.
Not really. It's sized and styled as an adult shooting earmuff, and it plays no audio, so a child expecting music or videos will be disappointed. For kids, the volume-limited SIMOLIO is the more appropriate choice.
No. It has passive noise cancellation from the over-ear cushions, which helps with focus, but it doesn't carry a Noise Reduction Rating. For genuine protection against loud noise, you want a certified protector like the Leightning L0F.
It depends on the trip. The Leightning folds to about four inches and is ideal for a range bag or hunt. The SIMOLIO is better for family travel: it has a carry case, Bluetooth 5, a 15-hour battery and a Travel Mode for noisy cabins.
