Frequently Asked Questions

Is this a genuine 3M Littmann stethoscope?

Yes. MyRespCo sells only 100% authentic 3M Littmann stethoscopes — factory sealed, brand new, with the Littmann manufacturer warranty included. We are a licensed medical equipment provider and do not carry counterfeit or grey-market products.

What is the difference between the Classic III and the Cardiology IV?

The Classic III is the gold standard for general clinical assessment — excellent for lung sounds, heart sounds, and bowel sounds. The Cardiology IV offers enhanced low-frequency acoustic performance for more advanced cardiac assessments. For most nurses, RTs, and generalist clinicians, the Classic III is the right tool.

Can this stethoscope be used for pediatric patients?

Yes. The Classic III (Model 5622) features a dual-sided chestpiece with a pediatric side — making it a single-stethoscope solution for both adult and pediatric assessments.

Yes. Every 3M Littmann Classic III purchased from MyRespCo includes the standard Littmann manufacturer warranty. MyRespCo also stands behind every sale — contact us if you have any issue with your order.
