The Eko Core digital attachment is as simple as revolutionary. Eko developed a device that allows digitizing any stethoscope. We ranked it as one of the best digital stethoscopes for 2021, even though it is not truly a stethoscope. The principle is to add a small, 2.8 inches (71 mm) x 0.9 inches (23 mm) and light, 1 ounce (28 grams), electronic attachment to your analog stethoscope.

Just toggling the button, the Eko Core digital attachment will enhance the amplification up to 40x, reduce the background noise by using noise-canceling technology and connect to a tablet or smartphone to take advantage of AI-powered FDA approved algorithms.

Easy to adapt and to use

The first version of the Eko Core Digital attachment was already a success, but Eko went one step further and redesigned the device to make it more comfortable and lighter. Installing it requires connecting the digital attachment to the original tubing on one side and connecting the chest piece using the adapter provided.

The digital attachment is compatible with most standard analog stethoscope brands such as 3M Littmann, ADC, WelchAllyn, Medline, and MDF. Check the full list on the EKO website.

Just like the excellent 3M Littmann Core Digital stethoscope, the Core digital attachment truly offers the best of the two worlds: analog and digital. Made of Polycarbonate thermoplastic, the attachment charges with a mini USB port and offers up to eight hours of continuous use battery. It is more than enough for several days of intensive use. It will automatically switch off after 5 mins without use to preserve the battery life.
