NOT for Health Professionals
I am a Family Physician and warn other physicians that this is not an adequate auscultation tool. It is far inferior to a traditional stethoscope. I have tried it with just my I Phone and also with high quality bluetooth earpieces and also with professional hearing aids. The sound quality is poor and I cannot hear murmurs or bruits in any mode. Their return policy has a 25% "restocking fee" which is a scam and speaks to the low quality of the product. If you are a health professional, you will be disappointed if you try this product.
