Features

• Tunable diaphragm technology—a 3M invention—lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece
• Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds
• Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit
• Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove
