"This accessory may not be supported"

This is a bit annoying. I have a great little pair of Garmin 'in ear' ear phones which have served me well over two previous iPhones but now when I plug them in I get the above message. Dismissing it does no good but what does work is putting the phone on Airplane mode, unplugging and replugging the earphones. So this is a message and function generated by Apple. The specs are ok so why is Apple stopping me from using a third party device. Is there any solution to this? Or must I buy an overpriced Apple approved device? PS I did originally buy these from an Apple store.

You got it! Same happens with most 3rd party charging cables.

I get this message occasionally with two after market cables, I find, wiggling them around, while still pugged in helps get them working.

Yes, well I'm using the provided lightening bolt adaptor as the earphones are 3.5mm.

Curious, I'm using a set of Bose exercise earbuds with that adapter and I've never seen the message. I wonder how (and why) the system thinks a set of earbuds are not "supported?" Any chance the iPhone is somehow thinking they are BT and not directly connected? Do you use BT to connect to any audio devices?

Yes I have a Bose Colour Link Bluetooth speaker.
