Love the radiation question in your FAQ. It is confusing that you say in the FAQ that you personally change the foam tips weekly, but the product only comes with 3 pairs. What happens after 3 weeks? Will it be economical to buy these en-masse, or will you effectively pay double the price after a year of paying for tips that you have to throw away? It also seems very wasteful to recommend throwing them away every week.
Thanks! We will make it economical to buy them en-masse. Also, you don't have to throw them away weekly - that's just our hygienic preference. There are people that use the same foam pieces for months. You can wash them under the sink as well. Good comment though, I'll modify the answer to that FAQ
