The short answer (prices checked 2 November 2026)
- Best overall: ProCase 3 to 16 years, £9.99, declared SNR 27 dB, which is 37.0p per declared decibel. It is one of only three listings in the top twenty that names EN 352-1.
- Cheapest per pair: Floriogra six pack, £39.99 for six, so £6.67 a pair and 23.8p per declared decibel. The dearest in the set works out at 91.6p, so the spread is 3.85 times.
- Highest number on the box: Dr.meter at £13.98 with a declared SNR of 32 dB, the only one of the twenty naming EN 352-1 and UKCA together.
- Our audit finding: of the first twenty unsponsored results, 13 quote an SNR figure, 3 name EN 352-1, and none publishes the H, M and L values that EN ISO 4869-2 defines alongside SNR.
- The thing worth knowing before you buy: UK law caps a consumer category 3 firework at 120 dB measured 15 metres away. Subtract the best SNR here and you still get about 88 dB at that distance, so where a child stands matters more than which pair you choose.
Children's ear defenders sit at number 13 in Amazon UK's DIY and Tools chart this morning, three days before Bonfire Night. That is a seasonal spike you can watch happen: the same product sits nowhere near the chart in June. A search for "ear defenders kids" returns sixty results, forty eight of them unsponsored, priced from £5.97 to £39.99.
Nearly all of them print a decibel figure on the main image. We wanted to know what that figure means, where it comes from, and whether paying more buys more of it. The answers turned out to be more interesting than the shopping.

The 120 dB rule nobody mentions
There is a legal noise ceiling for fireworks sold to the public in Britain, and it is specific. Regulation 8 of the Fireworks Regulations 2004 prohibits supplying any category 3 firework that "produces a maximum A-weighted impulse sound pressure level exceeding 120 decibels". Regulation 8(2)(a) says where that reading is taken: a horizontal distance of 15 metres from the testing point, one metre above the ground.
Two things follow. The first is that 15 metres is the measuring distance, not a safety distance, and nothing in that regulation governs how close a child actually stands in a back garden. The second is that the cap applies to category 3 only. Category 4 fireworks, the ones used at organised displays, are not supplied to the public and carry no equivalent consumer noise limit.
Now put the two numbers together. The decibel thresholds that product listings and parenting articles quote, usually 80 dB or 85 dB, come from regulation 4 of the Control of Noise at Work Regulations 2005. Those are the lower and upper exposure action values for a daily or weekly personal noise exposure at work, with a 137 dB(C) peak figure alongside the 85 dB one, and an exposure limit value of 87 dB(A). They are workplace figures. Britain has no equivalent legal threshold protecting a child at a fireworks display.
What the arithmetic says
The simple way to estimate what a hearing protector leaves behind is to subtract its single number rating from the noise level. Here is that subtraction, starting from the 120 dB legal ceiling at 15 metres and allowing roughly 6 dB of fall off for every doubling of distance.
| Distance from the firework | No protection | SNR 24 dB | SNR 27 dB | SNR 32 dB |
|---|---|---|---|---|
| 15 m (the regulation's measuring point) | 120.0 dB | 96.0 dB | 93.0 dB | 88.0 dB |
| 30 m | 114.0 dB | 90.0 dB | 87.0 dB | 82.0 dB |
| 60 m | 108.0 dB | 84.0 dB | 81.0 dB | 76.0 dB |
| 100 m | 103.5 dB | 79.5 dB | 76.5 dB | 71.5 dB |
At the regulation's own measuring distance, the best pair in this roundup still leaves about 88 dB, above the 87 dB exposure limit value in the work regulations. At 60 metres, an ordinary SNR 27 pair gets you to about 81 dB, under the 85 dB upper action value. So the honest reading is that ear defenders and distance work together, and neither does the job alone. If you take one thing from this page, stand further back.
Be clear about what this arithmetic is. SNR is defined for subtraction from a C-weighted level and the 120 dB in the regulation is an A-weighted impulse figure, so the subtraction is an approximation. The action values describe daily exposure across a working day, not single bangs. We are using workplace numbers as a yardstick because Britain does not provide any other. That is the point, not a loophole in the sum.
How we picked these
We read the first twenty unsponsored results for "ear defenders kids" on amazon.co.uk on 2 November 2026 and opened every product page. From those we kept six that cover distinct jobs, each with a declared figure we could find on the listing or on the maker's own site, each in stock with a working buy box on the day. Prices are the buy box price read on 2 November 2026. Cost per declared decibel is the price divided by the stated SNR, which is a comparison figure and not a physical quantity, and we have said so wherever it appears.
Look Into has not handled these products: every figure comes from the maker, the listing or a named source, read on the date shown.
At a glance
| Pick | Price (2 Nov 2026) | Declared SNR | Per declared dB | Standard named on the listing |

Best overall
ProCase ear defenders for children, 3 to 16 years
£9.99 on 2 November 2026 · declared SNR 27 dB · 37.0p per declared decibel
This is the pair sitting in the DIY and Tools chart this week, and it is one of only three listings in the top twenty that names EN 352-1, the European standard for earmuffs. The listing gives a declared SNR of 27 dB and a stated age span of 3 to 16 years, which works out at 76.8p for each year of that span. At 37.0p per declared decibel it is the cheapest single pair here that both quotes a number and names the standard behind it.
The catch: The 3 to 16 year span is the listing's claim, and one headband covering a three year old and a sixteen year old is asking a lot of the adjustment at both ends. Try it on the child you bought it for before you trust the range.
Best for the highest declared figure
Dr.meter kids ear defenders, 32 dB SNR
£13.98 on 2 November 2026 · declared SNR 32 dB · 43.7p per declared decibel
The largest number in the set, and the only listing of the twenty we read that names EN 352-1 and UKCA together. Its title carries the SNR figure and the UKCA claim instead of burying them in the bullets, which is more than most of the category manages. At 43.7p per declared decibel it costs 18 per cent more per decibel than the ProCase while giving five more of them.
The catch: Thirty two decibels is the best figure on this page and it still leaves about 88 dB at the regulation's 15 metre measuring distance. It buys you a little headroom, not a different answer on where to stand.
Best for a group or a big family
Floriogra ear defenders for children, six pack
£39.99 on 2 November 2026 · declared SNR 28 dB · 23.8p a pair per declared decibel
Six pairs at £6.67 each, which is the cheapest per pair anywhere in this roundup and works out at 23.8p per declared decibel. The listing quotes SNR 28 dB and names EN 352. If you are kitting out a scout group, a classroom or a gathering of cousins for the fifth, buying in a block is the only move on this page that changes the cost per child rather than the cost per decibel.
The catch: Six identical pairs in one size. That is fine for a group of similar ages and awkward the moment you need a toddler fit and a teenager fit from the same box.
Best for babies and toddlers
Alpine Muffy Baby comfort ear defenders
£21.99 on 2 November 2026 · declared SNR 24 dB, from the maker · 91.6p per declared decibel
The only pick here aimed squarely at infants, and the one with the best documentation, though you have to leave Amazon to find it. Alpine's own product page states a "Safe attenuation of 24dB" and publishes the full octave band table behind it, from 14.5 dB at 63 Hz up to 35.3 dB at 8000 Hz, with standard deviations and expected values. That is the actual measurement data, and no Amazon listing in the category publishes anything like it.
The catch: The dearest per declared decibel at 91.6p, and the listing contradicts itself on age: the title says adjustable up to 36 months while the bullets say up to 4 years (48 months). None of the octave band data reaches the Amazon page, which leads with a hearing loss statistic instead.
Cheapest pair that states a number
Kids Ear Defenders 26 dB SNR earmuffs
£7.49 on 2 November 2026 · declared SNR 26 dB, title only · 28.8p per declared decibel
At £7.49 this is the cheapest single pair in the set that puts a decibel figure in front of you at all, and 28.8p per declared decibel undercuts every other single pair here. If the budget is the binding constraint and you need one pair for Thursday, it is the honest answer to that question.
The catch: The 26 dB figure appears in the product title and nowhere else. We opened the page and the bullet section is completely empty, with no standard named anywhere to say where the number came from. You are buying a number with no working behind it.
Best build for older children
PROHEAR kids ear defenders
£18.95 on 2 November 2026 · declared SNR 28 dB · 67.7p per declared decibel
Heavier cups and a wider headband than the budget pairs, aimed at children who will keep them on for a whole display instead of two minutes. The listing quotes SNR 28 dB and carries a CE mark. It is the comfort pick, not the value pick.
The catch: Nearly double the ProCase price for one extra declared decibel, at 67.7p per decibel against 37.0p, and EN 352 is not named anywhere in the listing.
What twenty listings actually claim
We opened the first twenty unsponsored results for "ear defenders kids" on amazon.co.uk on 2 November 2026 and counted what each one states. The scope was the product title, the bullet points, the technical specification tables and the product description. Anything that appeared only inside a product image was not counted, because image text is not readable as text.
| What the listing states | Out of 20 |
|---|---|
| Quotes an SNR figure in decibels | 13 |
| Names EN 352 anywhere | 4 |
| Names EN 352-1 specifically | 3 |
| Publishes the H, M and L values | 0 |
| Mentions a CE mark | 6 |
| Mentions UKCA | 2 |
| Quotes a single frequency figure in place of an SNR | 2 |
| States an age range | 6 |
Thirteen listings quote the number. Three name the standard the number is defined by. That gap is the finding.
Where does SNR come from? EN ISO 4869-2 is the standard that defines it. The ISO catalogue entry for that document says it "specifies three methods (the octave-band, HML and SNR methods)" and that "the octave-band, H, M, L or SNR values are suitable for establishing sound attenuation criteria". In other words SNR is one of a family, and the H, M and L values sit beside it to describe how a protector behaves against high, medium and low frequency noise. Not one of the twenty listings publishes them. A firework bang has a great deal of low frequency energy in it, and L is the value that would tell you how a pair handles that.
Two of the twenty quote something that is not an SNR at all. Both give "31 dB (2K Hz)", an attenuation figure at a single frequency of 2 kHz, presented in the same position on the image where every other listing puts its SNR. A single frequency figure will always look better than a single number rating, because the rating has to account for the frequencies where a protector performs worst.
The inversion: the dearest pairs document the least, on Amazon
The two best known branded pairs in the category are the Alpine Muffy Baby at £21.99 and the Alpine Muffy Kids at £21.49. Neither Amazon listing states an SNR figure in the sections we checked. The Muffy Baby bullets open with "Loud sounds can be quite harmful for babies, and every 8th child suffers from permanent hearing loss". The Muffy Kids listing leads with "Paediatrician Recommended", qualified further down as "Based on a USA survey of 152 paediatricians". Meanwhile the £9.99 ProCase and the £13.98 Dr.meter both name EN 352-1 and both print a declared SNR.
That reads badly for Alpine until you go to Alpine's own site, which is why we did. Its Muffy Baby page states a "Safe attenuation of 24dB" and then publishes the complete octave band table behind it, with mean attenuation, standard deviations and expected values at every frequency from 63 Hz to 8000 Hz. That is substantially more information than any Amazon listing in this category offers, and more than the three EN 352-1 listings offer too. The data exists. It just does not reach the page where people buy.
So the problem here is one of listing transparency, and Alpine's own figures look well supported once you find them. The practical effect still falls on the buyer. A parent reading only what Amazon shows them on 4 November gets a hearing loss statistic from the dear pair and a referenced standard from the cheap one.
Questions people ask
Is there a legal noise limit for fireworks in the UK?
Yes, for one category. Regulation 8 of the Fireworks Regulations 2004 bans supplying a category 3 firework that produces a maximum A-weighted impulse sound pressure level above 120 decibels, measured 15 metres away horizontally and one metre above the ground. Category 4 fireworks, used at organised displays, are not supplied to the public and are not covered by that figure.
Where do the 80 dB and 85 dB figures in product listings come from?
Regulation 4 of the Control of Noise at Work Regulations 2005. It sets a lower exposure action value of 80 dB(A) daily or weekly personal noise exposure with a 135 dB(C) peak, an upper exposure action value of 85 dB(A) with a 137 dB(C) peak, and an exposure limit value of 87 dB(A) with a 140 dB(C) peak. Those apply to people at work. There is no equivalent legal threshold covering a child at a display.
What SNR should I look for?
The honest answer is that the gap between 26 dB and 32 dB matters less than the gap between 15 metres and 60 metres. Every pair in this roundup sits between 24 and 32 declared decibels, a spread of 8 dB, while moving from the front of a display to the back of the field is worth about 12 dB. Pick a pair that fits and stand further away.
Does a higher price buy more attenuation?
Not in this set. Cost per declared decibel runs from 23.8p a pair for the six pack to 91.6p for the dearest single pair, a spread of 3.85 times, and the pair with the highest declared figure of all costs £13.98 while the £21.99 pair declares the lowest. What the extra money appears to buy is padding, adjustment range and a brand with a published measurement table.
Are ear defenders enough on their own?
By the subtraction above, no. At the 15 metre measuring distance in the regulation, even the 32 dB pair leaves about 88 dB, which is above the 87 dB exposure limit value in the work regulations. Pair them with distance and the numbers improve quickly.
