Hi to everyone!I am having issues....and I'm hoping someone can help! I will be starting Nursing School in January and my husband purchased a Prestige Stethoscope for me...but I can't hear with it...it's only on my right side that I hear "noise" and I'm wondering what you would recommend for purchasing. I have good hearing but it seems to be an issue with the earpiece and my left ear...I would appreciate any help available for this issue! Thanks!!!
