I've been using my lighting EarPods most of the time with my iPhone 7 but recently I tried my trusted BOSE in ears with the lightning to 3.5mm adaptor. They worked fine but after a while I noticed that the inline controls stopped working. I couldn't stop/start/change volume with them at all.
This happens regardless of the screen being on or off. Makes it impossible for me to use them whilst I'm on a conference call and I'll have to rely on the speaker until Apple supply a fix.
