I am amazed at what this has brought to the table for health care provides- especially with ones with hearing impairment I love that the eko core attachment let’s me make a stethoscope I already own electronic! You don’t have to go and buy a whole new stethoscope (unless you’re me and didn’t have a regular analog stethoscope) nor do you have to have a limited range on colours! I love that the core allows you to block background noise - which if you have ever needed to do an assessment in emerge or in a ward room... you get it. It also allows for a volume boost that is helpful for people that may have extra tissue around their abdomen or chest and your trying to hearing adventitious sounds. It also allows for a wireless headphone mode... for my this means using my hearing aids! I love that I can stream the sounds CLEARLY to my hearing aids I can hear heart sounds like never before and directly in my hearing aids.
