Littmann Classic III vs Cardiology IV Philippines: Which Should You Buy?
Share
Choose the Littmann Classic III (from ₱9,600) for med school, general practice and internal medicine. Choose the Littmann Cardiology IV (from ₱19,300) if you work in cardiology, critical care or emergency, where faint sounds in a noisy room decide the finding.
The Cardiology IV adds dual-lumen tubing, higher acoustic performance and a 7-year 3M warranty (vs 5 years). Both are genuine 3M stock at BeHealthy, an authorized 3M Littmann reseller.
Doble ang presyo, pero doble ba ang pakinabang? It depends entirely on what you listen for every day. For most clinicians the Classic III is the right instrument; for a smaller group the Cardiology IV earns its price on every shift.

The two share more than their price gap suggests: the same tunable-diaphragm principle, the same tubing length, and the same spare parts kit. The difference is in how much faint detail reaches your ears.
What the Extra ₱9,700 Buys
The Cardiology IV's advantage is concentrated in two places.
Two separate sound paths run inside a single outer tube. That keeps the channels from rubbing against each other and delivers sound to each ear independently, which helps with faint, low-amplitude sounds.
3M positions the Cardiology IV above the Classic III for detecting and characterising subtle murmurs, gallops and extra heart sounds. The gap matters most in a noisy ER or ICU, less in a quiet clinic.
7 years from 3M, against 5 years on the Classic III. On an instrument you will carry through residency, those two years count.
Tunable diaphragms on both sides, 27-inch tubing, and the same 40016 spare parts kit. Technique still matters more than either instrument.
How tunable diaphragms work: press lightly to hear low-frequency sounds (bell mode), press firmly to hear high-frequency sounds (diaphragm mode). You change what you hear by pressure, not by flipping the chestpiece. Both models work this way.
Which Littmann for Which Specialty
Match the instrument to what you listen for most, not to your title.
Faint murmurs, S3 and S4, and assessment in loud environments. The Master Cardiology (₱20,500) is the single-sided alternative for clinicians who prefer one large diaphragm and no chestpiece to rotate.
The standard instrument for physical diagnosis coursework and broad adult practice. Its pediatric side also handles occasional work with children.
Chestpieces sized for small chests. The Classic II Pediatric suits children; the Classic II Infant suits newborns and NICU work.
Built for nurses taking blood pressure and routine assessment, with a teardrop chestpiece that slides under a BP cuff. Our stethoscope guide for nursing students covers this path in detail.
Buying Genuine in the Philippines
Counterfeit Littmanns are common in local marketplaces, especially at the Classic III and Cardiology IV price points. They copy the look closely but not the acoustics — and the Cardiology IV's whole value is its acoustics.

Frequently Asked Questions
For cardiology, critical care and emergency work, where you need to characterise faint murmurs and extra heart sounds in noisy settings, the Cardiology IV's higher acoustic performance is worth the extra ₱9,700 or more. For general practice, internal medicine and med school coursework, the Classic III is enough, and the difference is better spent elsewhere.
At BeHealthy the Littmann Classic III starts at ₱9,600 for standard-finish models such as black, navy, Caribbean blue, ceil blue and pearl pink. Special-edition finishes such as smoke, copper and black edition are ₱10,400. All are genuine 3M stock with 3M's 5-year warranty.
At BeHealthy the Littmann Cardiology IV starts at ₱19,300 for the navy blue standard model. Mirror-finish, special-edition and rainbow-finish models are ₱22,600. All are genuine 3M stock with 3M's 7-year warranty.
Most medical students are well served by the Classic III. It has tunable diaphragms on both sides of the chestpiece and covers everything in physical diagnosis coursework. Students already certain they are heading into cardiology or critical care sometimes buy the Cardiology IV early, since it will last well into residency.
Both have a dual-sided chestpiece with tunable diaphragms on the adult and pediatric sides, and both use 27-inch tubing. The Cardiology IV adds dual-lumen tubing, which carries sound through two separate channels inside one tube, and higher acoustic performance. It also carries a 7-year warranty against the Classic III's 5 years.
For routine pediatric work the Classic III's smaller pediatric side is usually enough. For dedicated pediatric or neonatal practice, the Classic II Pediatric and Classic II Infant have chestpieces sized for small chests and infants, both from ₱9,300 at BeHealthy.
No. The Littmann line is sold online only through behealthy.ph and is not stocked in the BeHealthy branches. Orders ship nationwide with cash on delivery, and free shipping applies on orders ₱888 and above.
