This is a little annoying, but it handles it well. - Philips SHP9500 (simply one of the best, if not THE BEST, open-back headphones for under £100). Altogether, a good value.

Pairing/Convenience: 4/5Pairing was extremely simple with an iPhone 11 Pro. You get what you pay for so to me, they seemed kind of cheap looking.
