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 offers you extraordinary solutions to minimize tinnitus symptoms.
  • 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.

Great ear plugs

I brought some plugs for my daughter who is 8 for swimming. We have tried different plugs before and had problems with them falling out. We no longer have that problem so on that basis I would recommend this product.

Mathew C. (Totnes, GB)
Finally an ear plug that works

My daughter has very small ear canals and gets water trapped in her ears when swimming, this has lead to a couple of infections. Due to this she has to have ear plugs. I have tried every type and style but they either fall out or are very painful and uncomfortable to put in and wear (and then they fall out anyway). I read about Bollsen on a Web review and decided to give them a go as everything else had failed. All I can say is I am amazed as they actually work, they go into my daughters ears easily with no discomfort, and stayed in for her entire swim session with 0%water ingress. Bollsen earplugs are worth every penny and are the only earplug I have found that work for children with small ear canals. A truly great product.

Kidz+ Bollsen hearing protection

Great product!! My daughter had grommets fitted last September and needs to wear ear plugs for swimming and in the bath and these are super. Really easy to fit and she doesn’t even know they are there and she can still hear me.

Julie J. (Llanelli, GB)
Great product

Best ear plug I have used. Keeps water out but allows you to still hear everything. Really good fit and comfortable to wear. Would definitely recommend

Good update on delivery

We ordered them last minute as we needed them for my daughter on holiday. I paid for fastest delivery and sent a quick message asking nicely for a quick turnaround as we were going on holiday. I got an email back saying they would be sent out that day, and then a further personalised email with tracking info
