What is the Littmann CORE Digital Stethoscope? A Complete Guide
The 3M Littmann CORE Digital Stethoscope combines trusted acoustic performance with cutting-edge digital technology. This guide covers everything clinicians need to know about this innovative diagnostic tool.
Understanding the Littmann CORE: A Modern Digital-Acoustic Hybrid
The Littmann CORE bridges traditional auscultation and modern digital healthcare. Unlike fully digital stethoscopes, the CORE maintains classic acoustic listening while adding powerful digital capabilities through integrated technology.
The stethoscope functions as a premium acoustic device with the same sound quality as the Littmann Cardiology IV. Digital components enhance rather than replace this functionality, giving you the best of both worlds. Use it like a traditional stethoscope when needed, or activate digital features for amplification, recording, and analysis.
It seamlessly integrates with the Eko Health platform, transforming auscultation data into actionable insights through documentation, collaboration, and analysis capabilities.

Why the Littmann CORE is So Popular Among Clinicians
Healthcare professionals across specialities have embraced the CORE for several reasons:

Challenging Environments
Emergency departments, ICUs, and busy clinics often present acoustic challenges. The CORE's amplification and noise cancellation features allow thorough examinations even in difficult conditions.

Digital Recording
Capture heart and lung sounds to share with colleagues for second opinions, use for patient education, or maintain as part of medical records. This supports better clinical decision-making and continuity of care.

Proven Quality
The CORE maintains Littmann's reputation for durability and reliability. It withstands daily clinical use while providing years of service, combining trusted acoustic performance with innovative digital features.
Advanced Features That Set the Littmann CORE Apart
40x Sound Amplification
The CORE delivers up to 40x sound amplification, a game-changer for detecting subtle findings. This is especially valuable when examining patients with obesity, thick chest walls, or conditions producing quiet sounds.
The intelligent amplification system uses digital signal processing to boost quiet sounds while preventing distortion. Adjust levels on the fly to find the optimal setting for each patient. This extends the diagnostic capability of physical examination, helping identify faint murmurs, subtle rubs, decreased breath sounds, and fine crackles.
Active Noise Cancellation (ANC)
ANC filters out ambient environmental sounds that interfere with auscultation. Advanced algorithms identify and suppress background noise patterns while preserving the body sounds you need to hear.
This proves invaluable in high-noise clinical environments. Emergency departments with alarms and conversations no longer prevent quality auscultation. The system adapts in real-time to changing acoustic environments, maintaining optimal listening conditions wherever you practice.
Dual-Mode Listening
The CORE offers both analog and amplified listening modes. Analog mode provides the traditional acoustic experience for routine assessments, while amplified mode activates digital enhancements when needed.
Switch between modes intuitively mid-examination without interrupting patient care. Start with analog listening and quickly switch to amplified mode for subtle findings. Even if digital components run out of charge, the CORE continues functioning as a high-quality acoustic stethoscope.
Digital Integration: Recording, Visualizing, and Sharing with the Eko App
The Eko app transforms the CORE into a comprehensive auscultation platform. Through Bluetooth connectivity, unlock capabilities that extend far beyond traditional stethoscope functionality:
- Recording: Capture 15, 30, 60, or 120-second audio clips that sync to secure cloud storage
- Visualization: Display phonocardiograms and spectrograms showing visual representations of sounds
- Sharing: Securely transmit recordings to other providers for consultation, specialists can review sounds without requiring patient travel
- AI Analysis: AI-powered tools help identify conditions like heart murmurs or atrial fibrillation, augmenting clinical judgment
Dual-Sided Chestpiece and Tunable Diaphragm Technology
The CORE maintains the proven dual-sided chestpiece design. The adult diaphragm detects higher-frequency sounds, while the bell specializes in lower-frequency sounds.
Tunable diaphragm technology lets you hear both high and low-frequency sounds from one side by adjusting pressure. Light pressure emphasizes low-frequency sounds; firm pressure brings out high-frequency sounds. This streamlines examination technique.
The chestpiece is crafted from durable materials designed to withstand frequent cleaning with alcohol-based cleaners and other disinfectants.
Comfort, Durability, and Everyday Usability
The CORE prioritizes ergonomic design for extended wear:
- Soft-sealing ear tips create comfortable, secure fit with excellent acoustic seal
- Anatomically designed headset positions binaurals correctly, reducing pressure points
- Balanced weight distribution prevents neck strain
- Tubing resists skin oils, alcohol, and temperature extremes
- Intuitive user interface with responsive volume controls and clear battery indicators
All components support easy cleaning and disinfection for infection control protocols.
Battery Life and Reliability in Clinical Settings
The rechargeable lithium-ion battery provides up to three hours of continuous use in amplified mode. For most clinicians, this means multiple shifts between charges since the stethoscope only draws power when actively using digital features.
Charge via USB connection using standard medical equipment charging stations, computer ports, or wall adapters. A full charge takes approximately three hours. Automatic power-off when inactive conserves charge, and LED indicators provide clear battery status.
The dual-mode design means battery depletion never renders the stethoscope non-functional, it continues operating as a premium acoustic stethoscope even with a dead battery.

Who Should Consider the Littmann CORE?
Cardiologists find amplification and recording invaluable for detecting subtle murmurs and documenting disease progression.
Primary Care Physicians appreciate noise cancellation in busy settings and the ability to consult specialists without requiring patient referral.
Telemedicine & Rural Practitioners benefit from digital sharing capabilities, bringing expert consultation to underserved areas.
Medical Educators & Students use recordings for classroom instruction, self-study, and competency assessment. Visualization features help develop pattern recognition skills.
Intensivists & Emergency Physicians rely on amplification and noise cancellation to examine critically ill patients in high-noise environments.
