I recently acquired a pair of high-end earphones, and while the audio quality itself is excellent, there's noticeable background noise on low volumes or during track skips, not to mention the microphonics effect. It's likely coming from the cable itself, which thankfully I can exchange, but the fact that a high-end product exhibits this behavior is concerning.

I'm very much in favor of keeping the headphone jack, but we'll look back at these analog issues the same way we currently think about needle static from record players.
