How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want true passive earmuffs that protect a young child's ears from loud events, choose BANZ Bundle Baby Hearing; if you need a wired two-way radio headset with a boom mic and adjustable volume for noisy work, choose Retevis EHK012. These two products both fight noise, but they solve completely different problems. One is built for little heads at concerts and fireworks; the other is built for adults talking into a walkie-talkie on a job site.
• BANZ Bundle Baby Hearing — biggest strength: Purpose-built passive earmuffs for kids, with a rated Noise Reduction Rating and a lightweight, low-profile shell plus a bundled pair of sunglasses.
• BANZ Bundle Baby Hearing — biggest trade-off: It is a child's hearing protector only — no microphone, no radio connection, no volume control, and it is sized for infants and toddlers rather than adults.
• Retevis EHK012 — biggest strength: A two-pack of over-ear radio headsets with a boom mic, adjustable volume and a stretchy coiled cable that reaches from a belt-clipped radio to your head.
• Retevis EHK012 — biggest trade-off: It is designed for adults and only works when plugged into a compatible two-way radio via its K-head 2-pin connector; it is not a standalone hearing protector for a child.
• Who BANZ is for: Parents who want to shield a baby's or toddler's ears at loud events.
• Who Retevis is for: Adult radio users — security, events, retail, campus, warehouses — who need to hear and be heard in noisy places.
BANZ Bundle Baby Hearing is a passive noise reduction product in the purest sense: it does not generate sound, cancel sound electronically, or connect to anything. It simply puts a soft, foam-filled cup over a small ear and blocks part of the loud noise before it gets in. The data sheet lists it as Passive Noise Cancellation with a stated Noise Reduction Rating, and the padding is described as foam with a leather-like headband cover — the kind of detail that matters when you are asking a two-year-old to keep something on their head for an hour.
The design is aimed squarely at kids. It is listed for ages 2 years and up in the feature set, with a size range of ages 0–2+ years and an infant age range in the product details, so it is clearly meant for the smallest wearers. BANZ calls out a low-profile shape with no protruding parts that can catch on things, wide foam-filled cushions so it does not squeeze, and enough room inside the shells for the ears themselves. At 142 grams it is light enough that a child is less likely to fight it. The bundle also includes sunglasses, which fits the same outing: a sunny, loud event like a race, a concert, fireworks, or an airport.
Who should buy it: parents of babies and toddlers who want a dedicated, kid-sized hearing protector for sporting events, car races, music concerts, airports, wedding receptions, movies, or machinery. Who should skip it: anyone who needs to talk on a radio, anyone who needs adjustable volume or a microphone, and any adult looking for their own earmuffs — this is not that product.

Retevis EHK012 is a different animal entirely. It is a wired two-way radio headset — a two-pack, per the data sheet — with a condenser boom microphone that rotates up to 270 degrees so you can position it at your mouth. It plugs into a compatible walkie-talkie using a K-head 2-pin connector and lists compatibility with a long roster of Retevis models (RT22, RT21, H-777, RT68, RT22S, H777S, RB29, RT86, RT86S, RA79, RT68B and more), plus Baofeng radios such as the UV-5R and BF-F8HP, Kenwood walkie-talkies, and Pxton models.
The noise handling here is described as noise reduction and sound isolation, not passive cancellation in the earmuff sense. The over-ear cups use a sponge-filled dual cushion that reduces pressure for long wear, and the sound-absorbing sponge is meant to improve insulation. There is an adjustable volume knob on the side, and the sheet notes a maximum sound threshold of 82 dB — a useful detail if you care about capping how loud a call can get in your ear. The cable is a coiled, stretchable wire: roughly 116 cm unstretched and up to 280 cm stretched, which is the difference between a headset that yanks off your head when you turn and one that does not. It folds up for storage and the headband adjusts for different head sizes.
Who should buy it: adults who already own a compatible radio and need hands-free communication in a noisy environment — campus calls, retail floors, events, security patrols, warehouses. Who should skip it: anyone without a compatible two-way radio, anyone who wants hearing protection for a child, and anyone who needs a wireless or Bluetooth solution, since this is a wired K-head 2-pin headset.
Side-by-Side: Which Should You Choose?
• Best for two-way radio communication → Retevis EHK012. Boom mic, K-head 2-pin plug, adjustable volume.
• Best for loud family outings (concerts, fireworks, races) → BANZ Bundle Baby Hearing. That is exactly the use case the sheet names.
• Best for noisy job sites and hands-free talking → Retevis EHK012. The coiled cable and rotating mic are made for that.
• Best for a bundled value pick → BANZ Bundle Baby Hearing, since it pairs earmuffs with sunglasses in one package.
• Best for a two-pack → Retevis EHK012, which ships as a set of two headsets.
• Best for capped listening volume → Retevis EHK012, with its stated 82 dB maximum threshold and side volume knob.
• Best for lightweight wear on a small head → BANZ Bundle Baby Hearing, at 142 grams with a low-profile shell.
In my opinion, these two should not really be compared head-to-head, because they do opposite jobs. If I had a toddler and a loud event on the calendar, I would buy BANZ Bundle Baby Hearing — it is designed for exactly that child, in exactly that situation, and the bundled sunglasses are a nice bonus. If I ran a radio on a noisy floor, I would buy Retevis EHK012 instead, because a boom mic, adjustable volume and a stretchy cable are what actually make radio traffic usable. Pick by the person wearing it, not by the noise rating alone.
how do passive noise cancelling headphones work
Passive protection works by physically blocking sound rather than electronically cancelling it. A dense cushion seals around the ear and absorbs part of the noise before it reaches the eardrum. BANZ Bundle Baby Hearing is listed as Passive Noise Cancellation with a stated Noise Reduction Rating, so it works this way.
what is passive noise cancelling headphones
It means a headset or earmuff that reduces noise through materials and fit instead of electronics — foam padding, sealed cups, a snug headband. BANZ Bundle Baby Hearing fits that description with its foam-filled cushions and leather-like headband cover; Retevis EHK012 uses sponge-filled over-ear cups for sound isolation.
what does passive noise cancelling headphones mean
It means there is no battery, no active circuit and no anti-noise signal — just physical blocking. That makes passive gear simple and reliable, but it only lowers noise rather than erasing it. BANZ relies on this for kids, while Retevis combines it with a radio headset and volume control.
what are passive noise cancelling headphones
They are hearing protectors or headsets that cut noise by blocking it physically. If you want that for a young child, BANZ Bundle Baby Hearing is the match; if you want it while talking on a compatible walkie-talkie, Retevis EHK012 is the match. Check the current price on Amazon before you decide.
