Littmann® Core Digital Stethoscope

The Littmann CORE is an advanced stethoscope that combines traditional Littmann acoustics with digital amplification, active noise cancellation, and compatible Eko software features.

It is intended for trained healthcare professionals, including physicians, nurses, advanced practice clinicians, EMTs, and medical educators.

Digital mode offers up to 40 times amplification at peak frequency compared with analog mode.

No. The 40× specification applies at peak frequency. Actual amplification and perceived sound quality vary by frequency, volume setting, seal, placement, and clinical environment.

Active noise cancellation helps reduce distracting environmental noise so the clinician can focus more clearly on body sounds.

No. It reduces certain ambient sounds but cannot create a completely silent listening environment.

Yes. The user can switch between traditional analog listening and digitally amplified listening.

Use the controls on the digital module according to the manufacturer’s instructions. Review the user manual before clinical use.

Yes. It features a dual-sided stainless steel chestpiece with tunable diaphragms on both sides.

Yes. The larger side of the chestpiece is designed for adult assessment.

Yes. The smaller side supports pediatric auscultation when used by a trained clinician.

A tunable diaphragm allows the user to hear different frequency ranges by changing the pressure applied to the chestpiece.

Apply light pressure to the tunable diaphragm while maintaining full contact with the patient’s skin.

Apply firmer pressure to the chestpiece without lifting or repositioning it.

Compatible Eko software can display heart-sound waveforms in real time and may provide other connected auscultation features, depending on the subscription and region.

A subscription may be required for waveform visualization, AI analysis, and other software features. Check the current Eko plan requirements before purchase.

A compatible mobile device is needed to use connected software features. The stethoscope can still provide listening functionality without viewing a waveform.

No. A compatible phone or tablet is generally supplied separately.

Eligible Eko software may provide AI-assisted analysis that helps identify possible murmurs. Availability depends on the software plan, device, region, and regulatory authorization.

No. AI output is decision-support information and must be interpreted by a qualified clinician alongside the complete examination and appropriate diagnostic testing.

No. It is an auscultation tool and does not replace echocardiography, ECG testing, imaging, laboratory studies, or specialist evaluation when indicated.

Its amplification and active noise cancellation may help in challenging environments, but performance depends on background noise, fit, technique, and clinical conditions.

The chestpiece is made from stainless steel.

Two internal sound paths are contained within a single outer tube, helping preserve acoustic quality while reducing tube-rubbing noise.

The CORE uses snap-tight, soft-sealing eartips designed for comfort and sound occlusion.

The listed length is 27 inches.

Yes. The supplied product information identifies it as latex free.

Yes. Digital amplification, noise cancellation, and connected functions require power. Review the current charging and battery specifications in the manufacturer’s manual.

Battery runtime was not included in the supplied specifications and can vary with amplification, connectivity, battery age, and use. Confirm the current rating for the selected model.

Follow the manufacturer’s instructions. Do not charge or operate it in a manner not expressly approved for clinical use.

Wipe approved surfaces with a compatible disinfectant according to Littmann and Eko instructions. Follow separate guidance for the chestpiece, tubing, eartips, and digital module.

No. Do not immerse the chestpiece, tubing, or digital module unless the manufacturer explicitly states that a component is submersible.

No. Autoclaving can damage the acoustic and electronic components.

Use only disinfectants and concentrations approved by the manufacturer. Excess liquid and incompatible chemicals may damage the finish or electronics.

Compatible replacement diaphragms and eartips may be available. Confirm that accessories are approved for the CORE model.

The supplied specifications list a seven-year warranty, but the digital module, accessories, battery, or software may have different coverage periods. Verify current warranty terms before purchase.

Accidental damage, misuse, unauthorized repairs, and normal wear may be excluded. Consult the official warranty for complete terms.

Data handling depends on the Eko application, account settings, connected device, and enabled features. Review the current privacy and security documentation before using patient information.

Capabilities vary by software version, subscription, device, and healthcare system. Follow organizational privacy, consent, and documentation policies.

The physical stethoscope can be cleaned between users, but software accounts, saved data, and device pairing should be managed according to facility security policies.

Check the active chestpiece side, eartip direction, acoustic seal, volume setting, battery level, diaphragm condition, tubing, and digital module connection.

It may be a valuable learning tool, but students should confirm their school’s equipment and software requirements before purchasing.

Yes. App functions, subscriptions, device compatibility, regulatory availability, and AI features may change through software updates or policy revisions.

Verify the model, color, length, included accessories, charging requirements, compatible devices, Eko subscription costs, regional AI availability, and warranty coverage.
