The stethoscope has barely changed over the years. It now has AI (like everything else these days). Make of that what you will.

Digital stethoscopes offer amplified sound up to 100 times louder than their acoustic ancestors. They include active noise cancellation, real-time waveform display, and the ability to record and share data. So, which one suits you?

Three Devices

Eko CORE 500 — The All-In-One

Built-in screen, 3-lead ECG, 40× amplification, noise cancellation, and EFAST AI detection of murmurs, atrial fibrillation, and low ejection fraction. Aimed at point-of-care screening. Advanced AI requires an Eko+ subscription at approximately £119.99 / $119.99 per year, a figure you will either consider excellent value or quietly resent every January.

3M Littmann CORE — The Familiar One, Upgraded

Same 40× amplification and noise cancellation, AI murmur detection, and a one-touch toggle between analogue and amplified modes. No on-board ECG. The same Eko+ subscription at approximately £119.99 / $119.99 per year for advanced AI features. This is for clinicians who want progress without being made to feel like they are learning something new (though it can feel a little on the heavy side).

Thinklabs One — The Tiny Tubeless One

No tubing, no binaurals, and most importantly, no subscriptions. A 50g puck you listen to through any headphones, delivering over 100× amplification with five selectable audio filters. Connects via a trusty 3.5 mm jack. It is particularly useful for telehealth, teaching, heavy PPE environments, and clinicians who use hearing aids. It looks like a small prop from a science fiction film!

The Awkward Bit

The real challenge with this new tech isn't the accuracy, but how it fits into a busy shift. A recent study tracking over 12,000 patients found that while an AI stethoscope can flag complex heart conditions, a striking 70% of GP surgeries stopped using the devices or used them infrequently after a year.

The researchers noted that for these tools to truly succeed, they have to be better integrated into a clinician's existing daily routine rather than adding extra, clunky steps to patient care.
