I’ve got both the AirPods Pro and the Sony XM4. The AirPods are more stable in my ears when moving around with them in, but the Sony have far better audio performance and noise cancelling. They’re also more intuitive to use the features as they’re simply tap to operate, the AirPods need you to grab a tiny button on the stalk.
The AirPods are more comfortable to emplace, but silicone tips for the Sony resolve this, admitted by making them less stable in the ears when moving around.
I paid £180 for the XM4s in November last year and £125 for the AirPod Pro with Wireless MagSafe using an eBay discount code.
