What is the Littmann CORE Digital Stethoscope? A Complete Guide

The 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
Advanced Features That Set the Littmann CORE Apart
40x Sound Amplification
Boosts sounds up to 40x louder using digital signal processing — ideal for patients with obesity or thick chest walls. Adjustable on the fly to detect faint murmurs, rubs, and fine crackles.
Active Noise Cancellation
Filters out ambient noise in real-time using advanced algorithms. Maintains optimal listening conditions even in busy emergency departments or high-noise clinical environments.
Dual-Mode Listening
Switch between analog and amplified modes mid-examination without interrupting patient care. If the battery runs out, the CORE keeps functioning as a premium acoustic stethoscope.
Eko App Integration
- Record 15–120 second clips to secure cloud
- Visualise phonocardiograms & spectrograms
- Share recordings with remote specialists
- AI analysis for murmurs & atrial fibrillation
Tunable Diaphragm
Dual-sided chestpiece with tunable diaphragm technology — adjust pressure to shift between high and low-frequency sounds from one side. Built to withstand frequent alcohol-based disinfection.
Battery & Reliability
Up to 3 hours of amplified use per charge. Charges via USB in ~3 hours with auto power-off to conserve battery. Works as a full acoustic stethoscope even when battery is depleted.

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.
Frequently Asked Questions
How long does the battery last?
How long does the battery last?
Approximately three hours of continuous amplified use. Real-world battery life extends through multiple shifts since most clinicians use amplification selectively. Works in analog mode when battery is depleted.
Is it compatible with my phone?
Is it compatible with my phone?
The Eko app works with iOS and Android devices using Bluetooth 5.0. Most recent smartphones are compatible; check the Eko website for specific requirements.
Can I use it without the app?
Can I use it without the app?
Yes. All listening features including amplification and noise cancellation work independently. The app is only required for recording, visualization, and sharing.
How do I clean it?
How do I clean it?
Clean with alcohol wipes or standard medical disinfectants. Avoid immersing the digital module in liquid. Remove ear tips for thorough cleaning.
What's the difference from other digital stethoscopes?
What's the difference from other digital stethoscopes?
The CORE maintains full acoustic functionality alongside digital features, unlike some that rely entirely on electronic processing. It integrates with the comprehensive Eko platform while preserving the familiar Littmann acoustic experience.
Is it suitable for students?
Is it suitable for students?
Students may benefit from mastering basic auscultation with a traditional Cardiology IV first. However, students interested in telemedicine or those with hearing challenges may find the amplification immediately valuable.
Can I share recordings with patients?
Can I share recordings with patients?
Yes, for educational purposes to help them understand their condition. Always follow privacy protocols and obtain consent before recording.
How does AI-assisted diagnosis work?
How does AI-assisted diagnosis work?
The Eko app uses FDA-cleared algorithms to analyze recorded sounds for conditions like AFib and heart murmurs. These provide decision support but don't replace clinical judgment.
What if digital components fail?
What if digital components fail?
Acoustic components continue functioning normally. The 5-year acoustic warranty and 2-year electronics warranty provide protection. Surgo Med assists with warranty claims and repairs.
Does it work with electronic health records?
Does it work with electronic health records?
The Eko platform offers integration with certain EHR systems, allowing recordings to be saved directly to patient charts. Availability depends on your specific EHR system and institutional IT policies.
