Foam earplugs are designed for one use in industrial settings. They expand unpredictably, often fit poorly, and muffle sound in a way that feels disorienting. BOLLSEN Life+ uses a patented 2-lamella conical design in medical-grade silicone. It creates a consistent, comfortable seal each time, reduces noise by a certified 24 dB, and lasts up to 100 uses. One pair replaces roughly 100 packs of foam disposables.

Yes. Life+ is designed to reduce low-frequency noise (traffic, crowd noise, HVAC hum) while still allowing higher-frequency sounds to pass through. You will hear your phone alarm, announcements on the tube, and someone calling your name. It takes the edge off the environment. It does not seal you off completely.

That’s exactly what they’re built for. The 24 dB reduction brings the constant background hum of a commute or open-plan office down to a manageable level. A lot of users say it’s the first time they’ve been able to focus without needing headphones. They’re discreet enough that most people around you won’t notice them.

Comfort is one of the most common things reviewers mention specifically. The silicone is soft and the fit is low-profile, so there is no pressure build-up the way you get with foam. Most users wear them for two to four hours without any discomfort. If you have never found earplugs comfortable before, the AR KI TECH fit service can match you to the exact right size.

It is the reason our return rate is 3 per cent when the industry average is 15–20%. You upload two photos of your ears using your phone. Our AI analyses your ear canal dimensions and recommends the precise size for your anatomy. The correctly sized pair is then shipped to you. No audiologist visit. No guesswork. No earplugs that keep slipping out.

Absolutely. Life+ was originally developed as a sleep earplug. The flush, low-profile design means no protruding stem pressing against the pillow when you sleep on your side. Thousands of users wear them nightly. They are safe for regular nightly use and the soft silicone does not irritate the ear canal over time.

Each pair is rated for up to 100 uses. They are washable with mild soap and water, and come with an aluminium travel case to keep them clean and protected. At £29.95 for 100 uses, that works out to around 30p per use. A box of disposable foam earplugs costs roughly the same and gives you far fewer uses at far lower quality.

It means the noise reduction figure was measured and verified by PZT GmbH, an independent German testing laboratory (Notified Body No. 1974), across over 1,700 controlled tests. It is not a brand estimate. The 24 dB figure is a tested SNR (Single Number Rating) value. It reflects real-world performance in everyday environments, not just a laboratory peak result.
