  • 98% of customers surveyed are satisfied with the performance of our filter technology and have noticed an improvement of tinnitus symptoms.
  • The high-fidelity sound insulation (SNR 24 dB) enables very good attenuation of loud noises, yet conversations (e.g. swimming instructors) are perceived normally.
  • The conically shaped design with 2 lamellae fits your ear and is ideal for small and medium-sized ears and for a prolonged use.

  • The product offers you extraordinary solutions to minimize tinnitus symptoms

  • We are the first protection manufacturer of hearing-protection devices to introduce online ear measurement technology.

  • snorkelling, diving up to 3m
  • surfing and kitesurfing

BOLLSEN Hearing Protection provides an average noise reduction (SNR) of 24 dB. The attenuation value was tested by independent laboratories according to ISO standard 4869. A constant sound reduction at high (H), medium (M) and low (L) frequencies: H=24 dB, M=21 dB, L=19.

The lifetime of the earplugs depends on the frequency of use. Regular cleaning extends the life span considerably. We recommend that you replace the BOLLSEN earplugs after four months of daily use, which is more than 100 times. Earplugs that are not used daily will last longer.

Amazing performance!! Complete protection against water when swimming, easy to use and comfy. Absolutely worth it!

Liz M.
A happy customer!

The earplugs are perfect - work well don’t fall out and easy to use. The service we got for the order was also brilliant. Can’t fault the whole thing. Many thanks.

Marine P.
Excellent product and service

Couldn’t be more pleased with the products, it’s comfortable and diminishes noise significantly. Service was great, I recommend using their AI to determine what size you need. I liked that the company assigns you someone who you can be in contact with directly if need be. I received my purchase very quickly. Great company.

Total ear protection when swimming

I have struggled for years when swimming, always getting water in my right ear, that seems to take an age to either come out or dry up.
After sending photos of my ears to Bollsen, I was a little sceptical as to whether these would work.

I can confirm they do, 100% watertight. No water in my ears at all. Brilliant. I will be using them every time 🙂

I can’t live without my Bollsen!

These ear plugs have given me my sleep back! I am now back sleeping through the night without being disturbed. I am so grateful for the sleep I have regained! And the ones with AR KI Tech are worth every penny extra!
