How is it obsolete, I understand a lot of people not needing it but all Audiophile products still need a physical connection in the form of 2.5, 3.5 or 4.4mm jack. 3.5mm has been a standard for the longest time.
I’d rather have that instead of a additional adapter to connect my iems. Only benefit in my case was that it allowed me to use a balanced connection for the same added cost.
That’s the whole point of gamification mechanics, there’s a fine line between grind and good gameplay which needs to be masterfully balanced
