3M Littmann Classic III Monitoring Stethoscope, Gray, 27" Tube

The 3M Littmann Classic III Monitoring Stethoscope is a trusted choice for nurses, physicians, and students who need reliable acoustic performance for everyday patient assessment. Featuring a durable gray finish and a 27 inch tube for extended reach, this stethoscope is built for clinicians who move between patients throughout long shifts and need dependable, consistent sound quality.

The convertible, double-sided chestpiece is easy to grip and rotate, allowing quick transitions between the diaphragm and bell sides for monitoring a wide range of body sounds. With the tunable diaphragm technology, users can simply adjust listening pressure to capture both high- and low-frequency sounds without switching chestpieces, making it a versatile tool for routine auscultation and monitoring tasks.

Comfort is built into every part of the design. The headset can be adjusted by squeezing or pulling apart the ear tubes for a secure, personalized fit, while the soft ear tips conform naturally to the wearer's ears. An acoustic seal helps block out ambient noise, so clinicians can focus on subtle heart, lung, and bowel sounds even in busy clinical environments.

Constructed with next-generation tubing, this stethoscope resists deformation and helps maintain its shape over time, supporting long-term durability. Whether used at the bedside or in a fast-paced clinical setting, the Littmann Classic III remains a dependable choice for accurate, everyday monitoring.
