Littmann Cardiology IV Stethoscope

Listen with precision. Diagnose with confidence.

The Littmann Cardiology IV Stethoscope is built with cardiology-grade precision to help clinicians catch the subtle sounds that matter most. Featuring a tunable diaphragm and a significantly larger, deeper chestpiece than the Classic III, it's engineered for confident diagnosis across a wide range of clinical settings — from routine check-ups to fast-moving critical care units.

Key Features

• Superior acoustic sensitivity — isolates faint sounds such as aortic stenosis, S3 gallop murmurs, and subtle pulmonary anomalies.
• Tunable diaphragm technology — switch between low and high frequency sounds simply by adjusting pressure on the chestpiece, no need to reposition or flip it.
• Larger, deeper chestpiece — roughly 40% larger and 60% deeper than the Classic III, suited to both adult and pediatric patients.
• Versatile across care settings — ideal for ED, ICU, Cardiac ICU, and step-down units where fast, reliable assessment is critical.
• Latex-free construction — Next Generation Tubing contains no natural rubber latex or phthalate plasticizers.
• Lightweight, all-day comfort — lighter than many comparable stethoscopes on the market, reducing fatigue during long shifts.
• Handcrafted quality — designed and assembled in the USA from globally sourced materials under strict quality controls.
• 30+ colors and finishes — including standard, mirror, and rainbow chestpiece finishes, plus satin-finish tubing options.
• 7-year warranty for long-term peace of mind.
