Earphones / Headphones: Where to try, what to buy?

Regarding the Bose 700 : https://www.bose.co.uk/en_gb/products/headphones/noise_cancelling_headphones/noise-cancelling-headphones-700.html

Bose AR-enabled products have motion sensors embedded inside that can detect your head orientation and body movement while you wear them. Bose AR-enhanced apps can then use this information along with location data from your mobile device to offer you audio content tailored to where you are and what you’re doing.

I just cannot think of how location data from my phone is ever going to be useful to "offer audio content"... except for adverts.

So having adverts via headphones are a selling point?!
