As a flight RN/Paramedic I use this model and can hear no difference when compared to previous littmanns that I've owned (and I'm hard of hearing). It also weighs the same as the Classic II. The nice thing about the ADC brand is it doesn't go "missing" as often as my fancy Littmanns did. Let's face it, as an RN or Paramedic you don't listen to anything that requires a cardiologist level stethoscope. This model is more than adequate for listening to standard heart tones, breath sounds, bowel movements, blood pressures, etc.. save yourself the money!
