  1. Thank you, Pam, for this post! My mom is a nurse and she is always on the lookout for new equipment! Maybe an electronic stethoscope would make me her favorite daughter when her birthday comes around lol!

  2. Thank you for this amazing collection! I find the bluetooth item fascinating but the more practical product is the digital products more accurate. Thank goodness for noise reduction. Keep up the good work Pam, you are doing amazing!!

  3. I work in a care home and this stethoscopes would be so helpful has its always noisy all the time and I like the feature from the Bluetooth. Very helpful, thank you.

  4. I do not think I will go with the ThinkLabs One Electronic Stethoscope. 2.5 stars is way too low for me. I do not want to run into any trouble. The Littmann 3200 Stethoscope looks much more appealing or even the EKO Core Digital Stethoscope. 4.5 stars for both of them is reassuring.

    I do have a question though. When it comes to buying stethoscopes, do you think it is something health insurance would cover? I look forward to reading your response.

    Thank you for sharing and I hope you make it a great day

    • Hi Alex, I am glad that you found the information useful. And Yes most people like the EKO CORE and the Littmann 3200.

      To answer your question, it depends on what type of coverage you have and the coverage may also vary among insurance companies. I suggest finding out if your insurance covers it before buying. Unless of course you really need it and don’t care about the insurance coverage as much.

      Thank you for you time.

      Have a great day
