Why Maintenance Matters

Hearing protection relies on a good seal and sound-absorbing materials. Dirt, sweat, dust, and everyday wear gradually reduce performance. Flattened cushions on ear defenders or damaged earplugs can let more noise through than you expect.

Looking after your gear means you get the level of protection you paid for, rather than a false sense of security from worn-out equipment.

Looking After Ear Defenders

Ear defenders (including our yellow DIY-style and green electronic models) are designed for repeated use, but they do need regular checks.

• Wipe after use: Use a damp cloth to gently clean the cushions and headband, removing sweat, dust, and oils. Avoid strong solvents or harsh chemicals.
• Check the cushions: If the seals are cracked, hardened, sticky, or badly flattened, it’s time to replace them. Poor seals mean poor protection.
• Inspect the headband: The band should feel springy and hold the cups firmly to your head. If it has become very loose, the defenders may not clamp tightly enough to seal properly.
• Protect electronics: For electronic defenders, avoid soaking the cups and follow the manufacturer’s advice for cleaning and battery care.

Many professionals replace cushions every year or two, depending on use. For occasional DIY or weekend use, they may last longer, but it’s still worth checking them regularly.

Caring for Earplugs

Different types of earplugs need different levels of care:

• Foam earplugs: These are usually single-use. Once removed, they should be thrown away. Reusing foam plugs can be unhygienic and they may not expand properly the second time.
• Mouldable silicone plugs: Soft silicone sleep and swimming plugs, like our purple plugs, can be reused many times. Keep them clean and free from hair and dust, and follow any washing instructions on the pack.
• Filtered or impulse earplugs: Wipe gently with a soft, slightly damp cloth and let them dry before putting them back in their case. Avoid soaking the filters.

Most reusable plugs come with a small case or tube. Use it – loose plugs in a pocket or bag quickly pick up fluff and dirt, which can irritate your ears.

Storage Tips

Where you keep your hearing protection makes a difference too:

• Avoid leaving ear defenders on dashboards or near radiators, where heat can warp the plastic and harden the seals.
• Store earplugs and defenders in a clean, dry place when not in use.
• Keep reusable plugs in their case to protect them from dust, moisture, and damage.

For work, many people keep a dedicated hook or box for defenders and a spare set of plugs in their tool bag, glovebox, or coat pocket.

When to Replace Hearing Protection

There’s no single rule for when to replace hearing protection, but some signs are clear:

• Ear defender cushions are cracked, stiff, flattened, or uncomfortable.
• The headband has become loose and no longer holds a firm seal.
• Reusable earplugs are torn, misshapen, or no longer seal properly.
• Filters or valves in impulse/sonic plugs are damaged or blocked.

If you notice that noise suddenly seems louder than it used to when you’re wearing your protection, it’s a good time to check fit and condition – and replace anything that’s past its best.

Make Care Part of the Routine

Hearing protection works quietly in the background, so it’s easy to forget about it once you’re used to wearing it. Building a quick visual check into your routine – for example, before starting a shift, a day’s shooting, or a DIY project – helps ensure everything is still doing its job.

Clean, well-maintained defenders and earplugs are more comfortable, more pleasant to use, and more likely to give you the protection you expect every time you put them on.
