Holding the power button on an Omnia rechargeable until the green LED light blinks three times will shut that HA down. You can then hold the power button down until the HA comes on again and reboots (green LED lights). It takes less than a minute to do this. Inserting an HA into the rechargeable case and removing it will also reboot the HA. (works for Ones and Quattros, too - and with a little practice, you can reboot by holding down the button while still wearing the HA’s).
I have experienced a connectivity issue with the Smart 3D app that I’ve associated (rightly or wrongly) with upgrading my iPhone to iOS 16.3.1. Rebooting my iPhone usually fixes that connectivity issue, and if not, rebooting the affected HA will. AFAICD, the connectivity issue does not affect battery runtime. The most recent Smart 3D app update seems to have largely fixed the occasional loss of connectivity to my iPhone and any BT connectivity problems walking by the house that seems to emanate a lot of EMI in my neighborhood. iOS 16.3.1 and Connectivity Issues - #40 by jim_lewis.
If you check out the ReSound literature, you can stream constantly with the Ones and the Omnias, and at most, the 30-hour runtime will be reduced to 25 hours or so. (The Omnias are supposed to have even less reduction in runtime than the Ones).
My audi has fit a number of patients with ReSound One or ReSound Omnia HA’s and has mentioned no problems with reliability. I had previously complained to her about my perceived reliability of my ReSound Quattros. I suffered a number of external mic failures for my left HA (I was cleaning the microphone openings with a Jodi-Vac, which I’ve stopped doing). So I think she would have told me if she’s had a problem with either the Ones or the Omnias. In fact, she said the only difference her patients had consistently reported to her between ReSound HA’s and Phonak HA’s is less hair rubbing sound against the external mics with Phonak HA’s.
