We are specifically interested in your YesEar plugs NS4000, FL3000, and BA2500-K. Are these items CE approved? Have you applied for a 510k from the FDA? Do your ear plugs carry any special approvals by recognized international testing organizations? Please send samples of these earplugs to my attention, Kam Stryzewski in New Products, so that we may review the quality and decide whether or not we would like to purchase them in the future.Thank you,Kam StryzewskiNew Products Coordinator
