The Brazilian Portuguese translation of the app is terrible. For example, the word “patients” should be translated as “pacientes”, but it was translated as “doentes”, which means sick people.

The Brazilian Portuguese translation of the app is terrible. For example, the word “patients” should be translated as “pacientes”, but it was translated as “doentes”, which means sick people.
The app makes it IMPOSSIBLE (on purpose) to share the recorded heart/lung sounds to people who dont have the app. This is absurd. See you in court!
Hey everyone, I'm a doctor, and I have noise-induced hearing loss. I recently bought the **3M™ Littmann® CORE Digital Stethoscope**, and I'm currently trialing two premium hearing aid brands: the Phonak Audéo Lumity and the Oticon Real 1. Both hearing aids are amazing in terms of sound quality and advanced features. My problem? I can't hear my Littmann stethoscope through either of them! I've tried connecting my Littmann CORE to my AirPods, and it works perfectly. The sound is crystal clear, like I have perfect hearing. But when I try the exact same connection process with either of my hearing aids, it's a nightmare. The sound is incredibly distorted. If I tap the stethoscope, it sounds nothing like it should, basically no sound. I spoke with audiologists from both Phonak and Oticon today, and neither could help me. They both called their respective tech support lines and told me to come back in two weeks, but two weeks is a lifetime. I'm a doctor, and I need to be able to hear heart and lung sounds. I can hear *way* better using the Littmann connected to my AirPods or by just taking the hearing aids out and listening directly. These are both incredibly expensive hearing aids, so I'm shocked that this connection is so bad. **Here's how I'm connecting everything:** 1. Turn on the Littmann CORE. 2. Open the Eko app. 3. Connect my phone to the Littmann via Bluetooth. 4. Connect my phone to my hearing aid via Bluetooth. 5. Horrible, garbled sound. If I play audio from YouTube or make a phone call, the sound through the hearing aids is perfectly fine. It's specifically the Littmann CORE connection that's the issue. Has anyone else experienced this? Any audiologists or doctors out there who can offer some advice? I'm desperate for a solution. It is a shame that a 800 USD stethoscope connected to a 4000 USD hearing aids sounds like the worst connection in the world. I am really disapointed and counting with you guys. Thanks in advance for any help!
Produto que faz a Littmann parecer o que realmente é uma mentira, uma Piada. O EKO Core está acima das expectativas clínicas e científicas, é preciso melhorar ainda mais o aplicativo. Produto acima da média.
