WHAT MAKES OUR PRODUCT SPECIAL IF COMPARED TO THE OTHER EARPLUGS?
Based on 1700 different tests and years of development, we were the first to have combined two technologies and thereby developed the AR KI Tech technology (click here). The latter offers a consumer an online ear measurement technology based on the computer-aided augmented reality (AR – measurement of the ear canal) and the use of artificial intelligence (KI – comparison of empirical values), so that the customer receives the perfect earplug:
- The product gives you extraordinary possibilities for a balanced sleep.
- Unlike many other manufacturers, we have developed our current product in cooperation with our customers.
- We are the first protection manufacturer of hearing-protection devices to introduce online ear measurement technology.
The BOLLSEN earplugs are a cosmetic product and prevent excessive stress or damage to the inner ear from loud noises. Numerous independent tests in Germany prove the excellent quality on the one hand, and the outstanding guarantee promise on the other.
Our materials are carefully selected based on studies and benefit from the following properties:
- REUSABLE: The BOLLSEN earplugs are reusable and completely washable. In addition, our earplugs offer the best wearing comfort and reduce irritation.
- PRACTICAL: Our aluminium containers are lightweight and fit in your pocket, key chain or belt bags.
- HYPOALLERGENIC MATERIAL: Our transparent earplugs do not contain BPA, PVC, plasticizers, latex and cadmium. Ideal for people with allergies, cooks, drummers, or athletes. They are made from 100% natural silicone, and when they are burned, only carbon dioxide and water are produced.
Make sure that the earplugs are inserted, adjusted and maintained in accordance with the manufacturer’s instructions. Detailed instructions for use are supplied with the earplugs.
- Our 40-Days Money Back Guarantee: Regardless of your statutory right of withdrawal, you have a 40-day right of return for many products. For exceptions and conditions, see Return details.

Bollsen was recommended to me, so I decided to try them after trying many other brands that didn’t do me any good. These are perfect. They don’t let water through, so I am very satisfied with the purchase and I have already recommended them to a friend who started swimming in the sea.

No complaints so far, as I’ve only used them in the shower. As for their use for swimming, you need to make sure they fit snugly!
I bought the ear plugs after an ear infection – I swim most days and felt I needed to protect my ears from chlorine. Been using them now for 3 weeks and after a bit of a fiddle using them to start with (reading the instructions and studying the diagrams is a ‘must’!) I find they are completely waterproof, comfortable and so easy to use. Special thanks to Tom and Maya for all their help – the service from this company is brilliant. My order arrived so quickly and I will be ordering more soon for sure. Many thanks
