Standard foam earplugs are designed for industrial noise — they block as much sound as possible. BOLLSEN Life+ are a passive silicone earplug (SNR 24 dB) that brings the volume down to a safer level — loud sounds like your alarm stay audible because they’re loud, not because highs pass through. They’re also reusable up to 100 times and made from soft medical-grade silicone, so they won’t irritate your ears or leave you with that plugged-cotton feeling in the morning.

Yes. This is one of the most common questions we get, and the answer is confidently yes. BOLLSEN Life+ filter low-frequency sound. Alarms, smoke detectors, and door buzzers operate at higher frequencies that pass through clearly. Thousands of customers rely on them every night without missing a single morning alarm.

They’re built for side sleepers. The patented conical design has no protruding stem, so there’s nothing pressing against your pillow or pushing back into your ear canal when you roll over. The silicone is medical-grade and genuinely soft. Most side sleepers tell us they forget they’re wearing them within five minutes of lying down.

BOLLSEN Life+ comes in three sizes. If you’re unsure, use AR KI TECH: upload two simple photos of your ears on your phone and our AI matches you to the exact size in seconds. It’s the same technology that’s brought our return rate down to 3%, compared to an industry average of 15–20%. No guesswork, no sending things back.

Up to 100 uses per pair when washed and stored properly using the included aluminium case. At £29.95 per pair, that works out to roughly 30p per night. Compare that to disposable foam earplugs at 10-20p per use with no washability and no fit quality, and Life+ is the obvious long-term choice for anyone serious about their sleep.

Yes, provided you keep them clean. BOLLSEN Life+ are made from BPA-free, PVC-free, latex-free medical-grade silicone, which is the same material used in medical devices precisely because it’s body-safe for extended contact. Wash them regularly with mild soap and warm water, let them dry fully before storing, and they’re perfectly safe for nightly use.

Simple: if you don’t sleep better with BOLLSEN Life+, return them within 40 days for a full refund. No forms, no conditions, no awkward questions. We offer 40 days rather than the industry-standard 30 because we know that forming a new sleep habit takes time. You need enough nights to know whether they’ve genuinely changed your rest — and we’re confident they will.

Life+ is rated at 24 dB reduction, independently certified by PZT GmbH in Germany (Notified Body No. 1974) across more than 1,700 tests. In practical terms: traffic outside, a humming boiler, a neighbour’s television, city ambient noise. The filter is tuned for low-to-mid frequency sound, which is the range that keeps light sleepers awake most often.

Most earplugs that fall out are the wrong size, or they’re foam that compresses unevenly. BOLLSEN Life+ uses a dual-lamella seal that creates a secure fit inside the ear canal without relying on expansion pressure. The AR KI TECH sizing service means you’re getting the size matched to your specific ear anatomy. A properly fitted Life+ should not move once seated, even if you shift position during the night.

Yes. Every pair of BOLLSEN Life+ ships with a compact aluminium travel case. It protects the earplugs when you’re not using them, keeps them clean between uses, and is small enough to live permanently on your bedside table alongside your other sleep essentials.
