The diaphragm and bell are a traditional time proven design for detecting the broadest possible range of high and low frequency sounds. Ultra Adsoft Threaded eartips are included for the ultimate in acoustic performance and wearer comfort along with a chestpiece key for removal of worn or damaged diaphragms.
