ER Experience

I purchased Eko device during the hight of pandemic because I needed a compact stethoscope device that reduced clutters that I had to carry while seeing patients in ER. This device fit the need. Compact in size, easy to protect by covering it w a glove, easy to disinfect, quick to use and put away in a pocket. Able to hear despite negative pressure pump in patient’s room. It is inconvenient and have to adjust to having a earbud in my hear while talking to the patient. However, I was safely and conveniently auscultate patients including COVID PUI with asthma/CHF,etc. Had a major set back with bluetooth connection for about 6 wks that was very frustrating & trying to resolve it by email was futile. I was appreciate of the support team who arranged for a zoom mtg. The issue is resolved now. The device connects seamlessly. It does drain phone battery and this is something I’ll have to collect more detailed data to give feedback. I find it necessary to carry my Litmann stethoscope tube with me in case of any malfunction w Eko. I prefer Littmann chest piece with the Eko attachment. Support team has been responsive. Emily has been very responsive, accommodating and instrumental in my continued use of the Eko attachment device. In a busy, loud ER in this unpredictable pandemic period, this device is innovated and has the edge.

Great customer service

I wrote a review with some of the shortcomings of the stethoscope/app and promptly received a response from the development team. It turns out that one shortcoming (the phone speaker audio) can’t really be fixed since it’s a speaker issue and not really an issue on the app’s part. The other one I mentioned, which was a loud noise after a recording playback finished playing through the stethoscope, was fixed very quickly. It turned out to be a known bug with some older models of the Eko Core, and I was immediately sent a replacement. The replacement was shipped without my needing to send the defective unit back first, since I would be without a stethoscope until the replacement arrived. I received the replacement unit within a few days, and I’ll now be sending back the defective unit free of charge. The audio bug seems to be gone, which is great, and it was a very easy process to fix the issue.

Developer Response ,

Thanks for the useful feedback! Since phones and computers are unable to emit low frequency heart sounds, we always recommend using headphones or speakers for playback. In regards to the quick record option, that is very good feedback and I'll make sure to pass this information along to the engineering team. Please feel free to contact if you are experiencing any bugs! We'd be happy to get it fixed for you.

Finally, something I can use with hearing aids

I have been needing to wear hearing aids for hearing loss and tinnitus for some time now, but being a health care provider I needed to be able to use a stethoscope. I have Bluetooth hearing aids but could not hear well enough connected to the EKO to the hearing aids. I bought a pair of behind the ear headphones, that I can put over my ears and lay around my neck, that work fantastic! I had a Littmann Cardiology stethoscope that I wasn’t using, due to bad tubing. I am using the head of the stethoscope on my Core EKO and I hear so well, even better than my newer Littmann IV stethoscope. I am so happy with this product!! I wish they had this available years ago when I worked as a flight nurse.
