Review: Best stethoscope iv ever h - I love this thing. I have been in healthcare for over six years and this is my second Litman cardiology four. The only reason this is my second one is because the first one was stolen. As long as I have my stethoscope with me, I will refuse to use any other stethoscope on the ambulance. There is a huge sound difference that sets aside the stethoscope from any of the normal cheap agency stethoscopes that are provided. Yes, it is a little expensive, however, considering that you can hear significantly better when listening for a blood pressure or lung sounds, I see it as a huge value for what it is. The ear tips are also significantly more comfortable than the standard hard plastic on the Cheapos.

### ⭐⭐⭐⭐⭐ Acoustics are great
*by J***N on January 19, 2026*

I'm a nursing student and wanted the best stethoscope for clinicals. Based on the reviews and it being on sale, I decided to go with this one. Tested it out and the acoustics are great. The sounds of the heart and lungs is so clear. I often feel I have trouble hearing but this stethoscope gives me confidence I won't have issues when assessing a patient in a busy, noisy clinic. My stethoscope is pretty and I like the rainbow chest piece. I would prefer the package be wrapped to know that it is new and not previously used. Mine looks new; however, without the wrapping, it makes me think it was a return. Nevertheless, the stethoscope is very nice and the sounds are clear and loud.
