The 3M™ Littmann® Cardiology IV™ Stethoscope is designed for clinicians who require outstanding acoustic performance combined with exceptional versatility. Its innovative design provides a single-piece tunable diaphragm on each side of the chestpiece.

• Outstanding acoustics with better audibility of high-frequency sounds (adult side, firm pressure).
• Tunable diaphragm: Hear high or low frequency sounds by slightly adjusting pressure on the chestpiece.
• Dual-lumen tubing: Two sound paths in one tube eliminates the rubbing noise of traditional double tubes.
• Next-generation tubing lasts longer and resists stains. Not made with natural rubber latex or phthalate plasticizers.
• Headset is easily adjusted for individual fit and comfort. Angled eartubes align with ear canals.
• Seven-year warranty provides greater peace of mind
• 27 inch tubing
