Interesting. There the “features” description is the following (emphasis mine):
BLE(1 & 2 MBit+Proximity), MI, Magnetic charging @135k, rechargeable battery
So, there is magnetic charging at an RF of 135 k(Hz) of a rechargeable battery.
Relative to my previous post about a battery door in the DURR1 and your remark, @narenkona, that previous FCC docs for earlier GN HA’s have the same battery door reference, maybe all GN devices of this class insert the (permanent) rechargeable battery through a “door” that’s then sealed shut? The earlier documentation I referred to claimed they couldn’t put the FCC ID on the device anywhere else because a) a label would irritate sensitive ear skin, and, b) the label might come off.
We’re all just guessing. ReSound usually announces new devices not too long after FCC approval so something more definite should come out in the next month or two. Maybe whatever has to await an announcement by Apple at the “Wonderlust” event on 9/12/23 (10 am, PDT in the U.S., 1 pm EDT). Save the Date: Apple Officially Announces iPhone 15 Event ‘Wonderlust’ - CNET. Perhaps there will be an AirPod/AirPod Pro announcement then that’s somewhat related? (more speculation!). Hard for me to believe that via MFI Hearing Devices Apple would provide Auracast capabilities without also providing those for AirPods at some model level.
