Had an original Eko stethoscope and loved it. My only complaint was the weight. Upgraded recently and can’t say enough good about it. I wear hearing aids and the soft tips still fit in my ears. The digital enhancement is wonderful and even in noisy rooms and with others talking and alarms going off, I hear faint heart and respiratory sounds. I have not used the Bluetooth capability with my Covid-19 patients but as I see more, I will probably do so. The Bluetooth connects through my phone to my hearing aids. I have tried it but not in practice but will update my review when I do. Customer service has been wonderful and provided immediate assistance without question. I will definitely continue to use my Eko and recommend it to friends and coworkers.
