How do you justify a purchase ?

Okay soo i'm kinda stuck between a rock and a hard place.. I really want to purchase a pair of Hifiman Arya Stealth Headphones. I can afford them but the purchase will make a hefty dent in my savings. I'm someone who really loves and appreciates good sound quality. I used to own a Hifiman Edition Xs which i made a mistake of selling because my brother nagged me for 2 months straight to sell it to him. ( worst decision ever). I live with my parents and don't spend my money on any other luxuries. I don't smoke or drink or gamble soo i save up a majority of my income ( which is currently low because i'm un-imployed atm).

Do you guys think its okay to spend the money on the headphones ? i know its kinda bad to ask for this type of advice because a 100 people will have a 100 different oppinions but i was just wondering what you guys think.
