Music SoundPRO with AR KI TECH Measuring

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.
