Ear protection buying guide

Updated: 21 October 2026

An ear protection buying guide has to put the SNR against the task, because a higher rating is not automatically the safer buy. The Health and Safety Executive matches SNR to the noise of the job, not to a daily dose. The twelve amazon.co.uk listings on the [ear protection comparison](/hub/hearing-protection/ear-protection) run from £4.79 to £33.95, and this page is the rule you apply before those cards. Peter F. checked HSE pages and those listings on 20 October 2026. Nothing here was lab tested. A qualifying amazon.co.uk purchase can earn a commission at no extra cost to you.

Match SNR to the task

HSE’s public table is for the task, not a whole shift. At about 85–90 dB(A) it points to an SNR of 20 or less. At 90–95 dB(A) the band is 20–30. At 95–100 dB(A) it is 25–35. At 100–105 dB(A) it is 30 or more. Keep the ear under 85 dB and not below about 70 dB, or warnings get harder to hear. The table is not for strongly low-frequency plant noise. In this set the Optime III states 35 dB for 95–110 dB(A). The Optime I states 27 dB for 87–98 dB(A). A 35 dB cup is the wrong default for a short mow.

What the law triggers at work

If people are employed, the Control of Noise at Work Regulations 2005 set action values of 80 and 85 dB(A), and peaks of 135 and 137 dB(C), without counting protection. The limit at the ear, where protection does count, is 87 dB(A) and 140 dB(C). Protectors are available on request from the lower value, and must be provided, with a signed zone, from the upper value. That is an employer duty. A Saturday DIY job is not a hearing protection zone. The duty returns for employed people near an action value, for impulsive or strongly low-frequency noise, or when muffs mount on a hard hat.

Read the listing before the star rating

Stars in this set sit between 4.3 and 4.6, so they will not choose the SNR. Portwest Classic is £4.79 with no SNR in the file, so the HSE table cannot be applied from this capture. Alpine prints filters at 16, 19 and 22 dB, then other fields at 22, 20 and 19 dB. Quote the conflict. Do not replace the amazon 35 dB on B000VDX18E with a 3M UK page that says up to 34 dB, and do not award that page’s UKCA line to this ASIN. Use the URL when a second ASIN appears. Do not put an NRR in the HSE column.

Cups or plugs is the next choice

Once the band is plausible, cups suit noise you take off between cuts, and plugs suit glasses, dirty hands or music. The 3M corded plugs state 25 dB and the bullets say no roll-down. A lower price beside a higher printed SNR is not more protection on your head. Fitting and the NHS stop rules are on how to wear ear protection. Glasses, and wearing both without adding the SNRs, are on ear defenders or ear plugs. A gig belongs on ear plugs for concerts.

Common questions

What SNR do I need for a mower versus a grinder?
A short mow is often the moderate band. In this set the Optime I states 27 dB for 87–98 dB(A). A grinder is closer to the Optime III file, 35 dB for 95–110 dB(A), or the X2A at 31 dB for 94–105 dB. Those are the listings’ ranges, not a measurement of your shed. Low-frequency plant sits outside that HSE table.
What is the difference between 80, 85 and 87 dB(A)?
At work, 80 dB(A) is the lower action value, where protectors are available on request, and 85 dB(A) is the upper action value, where they are provided and the zone is signed. The 87 dB(A) figure is the exposure limit at the ear with protection worn. Peaks are 135 and 137 dB(C) for the action values and 140 dB(C) for the limit. That comparison is made by the employer. A home workshop is not that legal duty.
Can I use an NRR number in the UK table?
No. Put the stated SNR into the HSE bands. NRR on a spec line, including Dr.meter’s 26 dB beside an SNR of 31 dB, or Alpine’s NRR field of 19 dB, is a different label. The 3M plugs happen to print 25 dB in both styles, which still does not make the two scales identical in general. If the file has no SNR, as with Portwest, do not invent one from the star rating.
Why does one listing show two attenuation figures?
Some pages were not edited to a single claim. Optime I states 27 dB and also 26–27 dB, model dependant. Alpine’s bullets say 16, 19 and 22 dB filters while other fields print 22, 20 and 19 dB. Three listings print a second ASIN in the body. Use the URL ASIN and do not average the numbers into a cleaner figure the seller did not choose.
Does CE on a bullet mean the product is UKCA marked?
No. A CE or ANSI line in a bullet is what that bullet says. These amazon files do not state UKCA, including the Optime III file, even if a separate 3M UK page mentions UKCA for a related description. 'Professional ASIN certified' is not a standard. EN 352 is the family name for hearing protectors. The designated-standards notice says the attenuation figure need not be printed on the product, so you still read the declared SNR.
