Features:

• Tunable technology is a 3M invention that lets you shift between hearing high and low frequency sounds by simply adjusting how much you press on the chestpiece.
• Soft-sealing eartips give you a comfortable fit and an excellent acoustic seal; they snap tightly onto the eartubes for safety.
• Open bell stays clear of dirt and debris by keeping it covered with the small diaphragm.
• Adjustable headset lets you easily set the tension for head size and comfort just by squeezing or pulling apart the eartubes.
• No natural rubber latex or phthalate plasticizers are used in the tubing or any other component—to help protect human health and the environment.
• Made in the USA for consistent quality. We apply rigorous process and quality controls to every Littmann stethoscope. You’ll always get a durable, dependable, clinical tool that will serve you for years to come.
