The standard pair is our medium size, which fits most adult ears, so for most people there is nothing to choose. Kidz+ comes in one smaller size for children aged 3 to 12. If your ears are unusually small or large, or you want to be sure of the seal, add AR KI TECH to your order on the product page: after your order you send us two photos of your ears and we send the pair in the size that fits you, small or medium.

Start with what you will use them for. Life+ is made for sleeping, Music SoundPRO for concerts and gigs, Moto+ for riding, Watersafe+ for swimming, WorkPRO for noisy work and Kidz+ for children. Each line has its own filter and shape for that setting. Not sure which size you are? Use AR KI TECH and we will recommend one from two ear photos.

Hypoallergenic silicone that is free of BPA, PVC, latex and cadmium. The body is our patented conical shape with two lamellae, the soft rings that seal the ear canal. It stays soft and comfortable through repeated use, unlike foam, which is made for one wear.

Wash your hands first. Hold the earplug by its small removal tab, pull the top of your ear gently up and back to straighten the ear canal, then push the plug in with a slight twist until both lamellae (the two soft rings) sit inside and seal. Snug, not painful. The tab stays outside for removal. Care tips at our earplug tips page.

Rinse your earplugs with warm water after each use and add a little gentle soap if needed. Avoid hot water, alcohol and strong cleaners, which can damage the silicone. Let them dry fully, then store them in the BOLLSEN case, away from heat. Cared for this way, each pair lasts up to 100 uses. Full care guide at our earplug tips page.

Up to 100 uses. Wash them after each wear and store them in the case. Replace the pair when the lamellae lose their shape or no longer seal, which for nightly use is a little over three months. Foam plugs are single-use, so one BOLLSEN pair replaces around 100 of them.

One pair of earplugs and an aluminium keyring case, so they are always with you. The Music SoundPRO case has a rubber ring seal. The Life+ 10x Pack ships ten pairs in a tube instead of individual cases. The Life+ Pink Edition includes a small and a medium pair.

AR KI TECH sizes your earplugs from two photos. Add the AI Ear Measurement in the box under the add-to-cart button on the product page and place your order. Your order confirmation page then shows how to take one picture of each ear and a form to send them. We confirm by email once they’ve arrived. The AI reads your ear dimensions and tells us whether small or medium fits you, and that is the pair we ship. No moulds, no clinic visit, no extra equipment. Read more on the AR KI TECH page.

No. We do not make moulded earplugs. AR KI TECH picks the size that fits your ear, small or medium, from your two photos, so you receive a regular BOLLSEN earplug in the right size rather than a guess. That gives most people a snug seal without the cost and wait of a custom mould. If the recommended size still does not fit, contact us within the 40-day money-back period.

• A size chosen from your own ear photos, not a guess.
• A better seal, so the earplug stays in place and delivers the attenuation (noise reduction) it was tested for.
• No impressions and no appointment. You upload two photos from your phone.
• Fewer returns and exchanges, because the size is right first time.

Not completely. No passive earplug does. Life+ has an SNR (Single Number Rating) of 24 dB. That takes snoring from loud to background level rather than silence. You hear less of it. What remains is far easier to sleep through.

Yes. Life+ reduces sound by around 24 dB, its SNR (Single Number Rating), but it does not seal you off. An alarm, a crying baby or a smoke detector is loud enough to come through, only quieter. Snoring and traffic drop to a level you can sleep through. Test your alarm at its normal volume on the first night to be sure.

Music SoundPRO is a passive silicone earplug rated SNR 24 dB (Single Number Rating). It lowers the whole mix by roughly that amount, so you hear the music, just quieter, without the muffled feel of foam. It is not a flat filter. The highs are reduced slightly more than the lows (H 24, M 21, L 19 dB), so vocals and detail are still there, only at a safer level.

By 24 dB on the SNR (Single Number Rating) scale. Split by frequency, that is 24 dB for high sounds, 21 dB for mid and 19 dB for low. A 105 dB stage drops to around 81 dB in your ear, closer to busy traffic than to a jet engine.

Yes, only quieter. Moto+ is a passive plug, so it lowers everything by roughly the same 24 dB rather than picking out wind. Your engine, a horn behind you or a siren stays audible because those sounds are loud, not because a filter lets them through. With the wind roar cut back, an intercom at the same volume is easier to follow.

Yes. Moto+ sits entirely inside the ear canal with no stem, so a snug helmet or the cheek pads do not press on it. The conical body with two lamellae (soft rings) adapts to your canal, and the silicone is hypoallergenic. If your helmet is a tight fit, put the plugs in first and settle the helmet over them.

Yes. Watersafe+ has a two-lamella silicone body (two soft flanges that press gently against the wall of the ear canal), and it seals the canal so water stays out while you swim. The seal holds through jumps, flip turns and open water. Fit decides everything. Push the plug in until both flanges sit inside the canal and nothing feels loose. Water getting in means it is not seated.

That is a question for your ENT or GP, not for us. Watersafe+ seals the ear canal and keeps water out while you swim, which is what a clinician usually means by keeping the ears dry. Whether you should swim at all, and how soon after surgery, depends on your case. Ask first. If you have been told to keep water out, that is what these earplugs do.

WorkPRO is rated at an SNR (Single Number Rating) of 24 dB, with H 24, M 21 and L 19 for high, medium and low frequencies. The reduction is not even across the range: roughly 22 dB in the lows and mids, rising to 35 dB at 8 kHz. You will notice a grinder’s shriek cut more than an engine’s rumble.

As the plug under your ear defenders, yes. Gunfire is an impulse of 140 dB or more. An SNR (Single Number Rating) of 24 dB describes continuous noise, not a muzzle blast, so we do not quote it for shooting. WorkPRO sits flush in the canal, which is why range users double up: earplug in, defenders over the top. The same goes for police and military users.

Kidz+ is made for children aged 3 to 12. It comes in one size and one colour, turquoise, with a smaller-diameter insert than our adult plugs and extra-soft silicone, so it sits in a small canal without pressing. It is not for babies or toddlers; for children under 3 an over-ear earmuff is the usual choice. Once your child outgrows it, move to the adult range.

Yes. Swimming is the main reason parents buy Kidz+. The silicone is water-repellent and the two soft lamellae (the flanges that make the seal) close the ear canal, so water stays out in the pool, the sea or the bath. Fit is everything with a small ear. Push the plug in until both flanges sit inside the canal, then have your child shake their head to check it holds.

Because that is where BOLLSEN began. The company was founded in Munich in 2016, and AR KI TECH is still made in Germany. BOLLSEN is now run by ERTG d.o.o. from Ljubljana, Slovenia, which is why our legal notices and EU returns address are Slovenian. Your order ships from our fulfilment centres in the UK, EU and US.

Yes. The conical shape of BOLLSEN earplugs is a protected design in the UK, the EU, the US and other markets, and BOLLSEN, Life+ and AR KI TECH are registered trade marks. It is our own design, developed over three product generations, not a rebranded generic plug.
