Kindly inspired by @heartbeat-eras, I recently ordered the HM-9260 digital stethoscope from HMYL and received it today! First impression is that it can compete pretty well with the amplified mode of my EKO Core attachment in direct listening mode, for a considerably lower cost price. The headset is a little less comfortable to me than that of a Littmann Cardiology, but it's easy to interchange parts :-).
Recording to post on Tumblr is still fairly tedious, since I can't attach the created wav files directly from the location where the app saves my recordings on my tablet. So I need to bring the saved wav file from iPad to iCloud, subsequently download it to my Windows PC, (if needed edit and) convert it to mp3 there to reduce file size, and then attach it to a Tumblr post. But I'm happy to do the effort for you all! So here is my first 1-minute recording on Erbs from my new toy - which contains a skip from excitement at the end. Feel free to leave a comment with your thoughts!
