XM4 vs XM5 for long term use

Hello everyone! Recently I’ve been looking for a new pair of headphones and I am between xm4’s and xm5’s. Normally I was going to go for xm4’s since I thought they would be cheaper but both of them actually have the same price on amazon and I am having a hard time deciding on which one I should buy. After seeing that they were going for the same price I actually was gonna go from the XM5’s but the problem of the hinge breaking makes me nervous and that really isn’t something that I want to gamble on because I am thinking of using these headphones for at least 4 years but then again will xm4’s hold up for 4 years?

What do you guys think I should do?
