You may need to perform this 3-step test cycle (over and over);
- Change Phone settings
- Save Phone settings to hearing settings and database
- Test with a Phone call
- Maybe set the phone level up to +9dB and see how that sounds? Maybe too loud? Try another test cycle with a lower volume.
- The Mic/phone level is for hearing people next to you during a phone call. Ignore this setting for now and leave it for last.
- Sound perception, Try Fullest, Try brightest, Maybe somewhere in-between? Adjust and test, Adjust and test.
- Low frequency enhancement, how much Bass do you like? Adjust and test, Adjust and test.
When/If you like your adjusted phone call settings, it's time to Go get a partner to speak to you during a phone call. Now adjust your Mic volume so that you hear Both the person on the phone AND the person next to you.
