Yeap, same thing is happening to me but with the right hand one.
£250?
Will be going to the Genius bar soon. Distortion during phone calls is so annoying.
I called apple and they made me reset them by folliwing these instructions.
There is a few more steps included with the reset of the AirPods…You can reset the AirPods by: 1.Put your AirPods in their case
Close the lid. Wait 30 seconds, then open the lid
2.Go to Settings > Bluetooth and tap the "i" icon next to your AirPods. Then tap Forget This Device, and tap again to confirm.
3.With the lid open, press and hold the setup button on the back of the case for about 15 seconds, until you see the status light flashing amber.
4. With the lid open, place your AirPods close to your device. Follow the steps on your device's screen.
These these did nothing for me I am afraid. So the lady said it might be a TIPS issue and sent me two sets. Seriously Though, they are virtually brand new.
So, off to Leicester Highcross for me. EVERY SINGLE Apple product I have bought in the past 5 years has failed! (apart from a second hand thunderbolt display).
The list so far is
2018 Macbook pro
Iphone X
Beats X headphones
Iphone 7
