Comfort, Fit & Seal (Matters More Than You Think)

Even the best stethoscope underperforms without a proper seal.

• Eartips: Try small vs large soft-sealing tips to get the best fit for your ear canal.
• Headset tension: Gently adjust the ear tubes for comfort and seal.
• Angle: Aim the eartips forward (towards the bridge of your nose) for correct alignment.

Tip: At StethShop, we can advise on eartip sizing and share quick fit checks before you buy.

Care & Maintenance (Keep It Crisp)

• Clean regularly with alcohol wipes according to manufacturer guidance.
• Replace diaphragms and eartips when worn—small parts make a big difference.
• Avoid extreme heat (e.g., hot car dashboards) to protect tubing.
• Store in a case if you toss it into a full backpack or kit bag.

FAQs

Is Classic III enough for clinical training?
Yes. It’s a favourite for students and generalists thanks to clear acoustics, comfort, and value.

Will Cardiology IV help me hear murmurs better?
It offers enhanced sensitivity at higher frequencies, which can help with subtle findings—especially valuable in specialist settings.

Is engraving worth it?
Absolutely. It reduces loss/mix-ups and looks professional. StethShop engraves free of charge.

What if I’m uncertain between the two?
Think about setting and stage. If you’re a student or in primary care, Classic III is excellent. If you regularly manage complex cardiac/respiratory cases, Cardiology IV is a smart upgrade.

How do I pick the right size eartips?
Start with soft-sealing large tips for most ears. If the seal feels too tight or you get discomfort, switch to small. Ask us for setup tips.
