Why Choose the Littmann CORE Digital Stethoscope?

Up to 40x Sound Amplification

Detecting subtle heart murmurs, lung abnormalities, and faint body sounds is easier than ever. Compared to analog mode, the CORE provides up to 40x amplification at peak frequency, allowing you to catch details that might otherwise go unnoticed—critical for accurate diagnoses and timely interventions.

Advanced Active Noise Cancellation

Busy clinics, emergency rooms, and hospital wards are full of distractions. The CORE’s active noise cancellation technology filters out ambient background noise so you can focus entirely on your patient’s heart and lung sounds. This means better clarity and reduced listening fatigue, even in the noisiest environments.

Comfortable, Soft-Sealing Ear Tips

Engineered with soft-sealing ear tips, the Littmann CORE provides both comfort and an acoustic seal that prevents sound leakage. This ensures high-quality listening while allowing healthcare professionals to wear the stethoscope for extended periods without discomfort.

Dual Listening Modes: Analog and Digital

Switch effortlessly between analog and amplified listening modes with the press of a button. The CORE also features dual tunable diaphragms for both adult and pediatric patients, making it simple to assess a wide range of sounds without repositioning the chestpiece.

Bluetooth Connectivity and Eko Software Integration

The Littmann CORE connects wirelessly via Bluetooth® to smart devices and integrates with Eko software. This allows clinicians to visualize sound waveforms, securely record patient exams, and build a library of heart and lung sounds for tracking and education. The ability to share recordings for collaboration is currently available for U.S. customers only.

Ergonomic and Durable Design

Designed with the user in mind, the Littmann CORE includes an angled headset for a proper ear fit and a stainless steel dual-sided chestpiece for both adult and pediatric use. It is built to withstand daily clinical use while maintaining the comfort and reliability Littmann is known for.
