The Problem Nobody Mentions at the Rescue Centre

Cats are not quiet sleepers. They purr at frequencies your brain cannot ignore, scratch at 3am, and reposition themselves across your face with zero apology. Most cat owners accept the resulting exhaustion as the natural cost of pet ownership. Sleep science disagrees. Chronic sleep fragmentation from recurring low-level noise raises cortisol, impairs memory consolidation, and compounds into the kind of tiredness that does not shift no matter how long you stay in bed. The cat is not the problem. The unfiltered noise is.

Questions? We've got answers.

Yes. Bollsen Life+ uses selective noise filtering, not total sound blocking. It significantly reduces low-frequency sounds like purring, movement, and background noise. High-frequency sounds including your phone alarm, smoke detector, and a cat yowling loudly remain audible. You will not sleep through your alarm.

Yes. The Life+ filter is designed to reduce the low-frequency, repetitive sounds that disrupt sleep (purring, pawing, gentle meowing) while keeping sharp, urgent high-frequency sounds clearly audible. If your cat is in genuine distress or crying loudly, you will hear it. The filter reduces ambient noise, not emergency signals.

Life+ was built with side sleepers specifically in mind. The patented 2-lamella conical design sits completely flush with the ear, with no stem protruding. Nothing presses into the pillow. Many of our customers had given up on earplugs entirely before this — other brands hurt by 3am and they’d stopped trying. This is the one that changed that for them.

Foam earplugs are single-use, often uncomfortable for extended wear, and block sound indiscriminately. Bollsen Life+ are reusable medical-grade silicone, independently certified at 24 dB, and designed to filter selectively. They are washable, last up to 100 uses, and do not expand inside the ear canal the way foam does. Most people who try both never go back to foam.

Yes. Bollsen Life+ are made from medical-grade silicone: BPA-free, PVC-free, and latex-free. They are safe for nightly use. The material is non-porous, so bacteria do not accumulate the way they do in foam earplugs. Simply rinse them after use and they are ready for the following night.

24 dB is a meaningful reduction. A cat purring registers at roughly 25 dB. Light traffic and most household background noise sits between 40 and 55 dB. At 24 dB of certified attenuation, the Life+ brings those sounds down to levels your brain can sleep through rather than registering as interruptions. Independently tested by PZT GmbH (Notified Body No. 1974) across over 1,700 measurements.

Life+ comes in standard size, which fits the majority of adult ears. If you want a guaranteed perfect fit, our AR KI TECH service uses AI to analyse two photos of your ears and ships the exact size matched to your ear canal. It reduces our return rate to 3%, compared to a 15-20% industry average. Visit bollsen-hearingprotection.com/ar-ki-tech/ to use it.

You have 40 days to try them properly. If you’re not sleeping better, contact us and we’ll refund you in full — no questions, no process. We offer 40 days rather than 30 because we want you to have real time to experience the difference, not a deadline that makes you rush the decision.

Each pair is rated for up to 100 uses. To clean, rinse under warm water and allow to air dry before placing back in the aluminium travel case. Do not use alcohol or abrasive cleaners. At 100 uses over a year, that works out at approximately 27p per night, which makes them one of the most cost-effective sleep investments available.

Bollsen Life+ comes with one pair of earplugs in your chosen size and a compact aluminium travel case. The case protects them between uses and fits in a bedside drawer, a pocket, or a travel bag.

“When ambient noise fragments your sleep night after night, the consequences build quietly over months — mood, patience, concentration, health. It’s a problem with a straightforward solution that most people simply haven’t been told about yet. Protecting your sleep environment is not a luxury, and Bollsen Life+ is the first thing I recommend to any client dealing with this.”

I have tried four different earplug brands over the past two years and none of them came close. The Life+ are certified 24 dB and I can actually feel the difference. Cat purring, bin lorry at 6am, upstairs neighbours: all of it becomes background. I woke up genuinely rested for the first time in months on the third night of using them.

Rachel T. / Trustpilot

The German lab certification was what convinced me. A lot of earplug brands make vague claims about noise reduction but Bollsen publishes the exact testing methodology and notified body number. I bought them sceptically after being disappointed by Loop. Two months in and I have used them every single night. The quality is clearly a step above.

James O. / Google

I was very sceptical about reusable silicone earplugs after years of foam ones, but the silicone material is genuinely different. No irritation, no feeling of pressure in the morning. I have washed mine probably 30 times and they are still performing exactly the same. Worth every penny of the £26.95 when you work out the per-night cost.

Priya N. / Trustpilot

I have two cats who both sleep on the bed and one of them purrs so loudly my partner can hear it from across the room. I honestly did not believe earplugs would help because I thought it was a comfort issue rather than a noise issue. On the first night with the Life+ I slept seven hours straight. That had not happened in over a year. I still wake up if one of them makes a panicked noise, but the constant low-level sounds are completely gone.

Sophie M. / Trustpilot

My cat is a rescue and has serious separation anxiety, which means she meows at night until I let her in and then she scratches at things until she settles. I was getting maybe five hours of broken sleep. The Life+ does not block everything but it takes the edge off enough that the scratching no longer wakes me. I went from dreading bedtime to actually sleeping properly. The alarm still wakes me, which was my main worry.

Dan K. / Facebook

I tracked my sleep with my fitness watch for a month before using the Life+ and for a month after. Deep sleep increased from an average of 54 minutes to 81 minutes per night. I was not expecting to see a measurable difference but the data is quite clear. The cat has not noticed any change in the relationship, which was also a genuine concern.

Lena W. / Google

I am a side sleeper and have always struggled with earplugs pushing against the pillow and causing ear pain by 3am. I actually gave up on them entirely for about two years. The Life+ design is completely different: flat against the ear, nothing sticking out. I wore them for eight hours on the first night and woke up with no discomfort at all. This is the first earplug that has actually solved the side-sleeping problem for me.

Anna C. / Trustpilot

I tried Loop Sleep and another well-known brand before these. Both caused discomfort after three or four hours on my side. The Bollsen Life+ are the first I have genuinely forgotten I was wearing. My partner noticed I had stopped pulling them out in the night and tossing them on the bedside table, which was apparently a nightly habit I was not even conscious of.

Marcus B. / Google

My ears are on the smaller side and I have always had trouble with standard earplugs feeling too large. I used the AR KI TECH service and the sizing was perfect on arrival. No adjustment period, no discomfort in the morning. After six weeks of nightly use they still feel exactly the same as the first night. The silicone material is noticeably softer and more flexible than anything else I have tried.

Isabelle F. / Trustpilot

I ordered the standard size and found after a week that the fit was slightly loose. I emailed the team and had a reply within a few hours. They sent out a replacement in a different size with no additional charge and the second pair was perfect. The 40-day guarantee is genuine: they mean it and the customer service reflects it.

Tom R. / Trustpilot

I contacted Bollsen with a question about whether Life+ was suitable for someone with narrow ear canals before ordering. The response was detailed, informative, and came back the same day. They recommended the AR KI TECH service rather than just taking my money on a standard pair. That kind of honesty is rare. I ordered and the fit has been excellent.

Claire S. / Google

I invoked the 40-day money-back guarantee after about three weeks because I was not finding the standard size comfortable. The refund was processed within two days with no questions asked. I then ordered again with the AR KI TECH sizing because I was so impressed by the service. The second pair fitted perfectly and I have been using them every night since.
