I bought the Eko for Covid care. I use one AirPod under my bouffant cap and put the Eko in a large glove. I felt this was easier to maintain than trying to wipe down my stethoscope. With an AirPod I can hear very well. Volume on my iPhone without AirPods is too soft for my hearing (I’m over 60). Might be ok for a younger person. I find it best to pair it to my phone before I go in the room and put it in a glove. I can turn it off and when I’m in the patients room it pairs pretty reliably when I turn it back on. I’m giving it four stars because I can’t get the volume high enough on my iPhone to hear well.
