Yeah, that comment also sent off internal alarms for me also. It would be a great blog post (or YouTube video) for someone to buy a bunch of stethoscopes and objectively test them. I would bet that there is a 10 USD model that is 98% as good as 200 USD models from 3M Littmann. And similar to the neverending arguments about "premium high-fidelity stereo equipment", I bet most doctors cannot tell the difference between the two when the logo/brand is hidden.
BTW: I found the 3M Littmann page on Amazon. The prices are wild: https://www.amazon.com/stores/3MLittmannStethoscopes/page/42...
Not wild when you consider the industry. Although those prices seem high perhaps by 20% compared to international markets.
IIRC in 2010 a Litmann Classic II was $60 today it's $100. That's what most medical students and doctors might use early in their career and it's probably nearly all the benefits of the premium lines.
But even ~$200 for their top tier lines are not expensive given their the tool of the industry.
That's a single year of JetBrains subscription? Or a single month of Claude? For something they could use for 10+ years.
The ~$500-700 electronic with recording stethoscopes always seemed gimmicky to me. But are legitimately useful for people with a hearing impairment.

I'd take this in a different direction, a common adage is that diagnosis is 80% history 15% examination, 5% investigation. In this case too the stethoscope performance is a slice of that 15%, and is dominated by the knowledge and experience of the user. If you don't know what to listen for and why (and many doctors won't compared to say a experienced cardiologist) they won't be able to hear it from a perfectly recorded FLAC file.
At the higher end it's also just smaller more specialist (cardiologiste, pædiatricians) markets that can command a higher price as a result.

It's the same as every other field, cars, phones, or computer cases, you name it. Something can be artificially expensive, but it can also be because it uses better materials, has more features, is built to higher standards. And some things can't be tested properly in a small scale review. Longevity, for example.
But there are factors that influence the premium price. The build construction - quality of the construction, quality and feel of materials, flexibility/rigidity of components, comfort of the ear tips and why not, even color options or the logo that shows you don't cheap out on equipment. Functionality - amplification, frequency response, double sided, 2 diaphragms can be used on children and adults. And then you have nice features like tunable diaphragms, or warm rims/sleeves for making it more comfortable for the patient.
Like for any other product, you'll save on the things you don't care about. The neck is stiff, the earpiece is uncomfortable, the tubing degrades, it's ice-cold, not great for kids or thin patients, but the sounds come in loud and clear enough and it's half the price.
