GB notification kcon

[inmnbob]

After upgrading to 2.3 I used my car BT and noticed a new notification icon that looks like an ear with a couple of lines next to it. This icon is still on despite the fact that I left the car and won't turn off even with a power down and pulling out the battery.

Any idea what this icon is and how to turn it off?

Could be hearing aid, go into call settings and check it if the hearing aid box is checked.
