This seems backwards to me, mostly. A decade ago, quality sound on the go meant a pocket headphone amp wired to deep-seated inner-ear earphones or clunky over-the-ear cans.

Today? Airpods Pro do the trick: the second- and third-generation models rival or exceed most wired options. And that makes sense: Apple's R&D spending and engineering capabilities for a product like Airpods dwarf the resources of traditional audio companies--the built-in DSP alone is a staggering achievement. So they ought to sound great, and they really do.

And that's before you even consider all the other capabilities, like taking calls, etc. My pocket amps and wired 'phones (Etymotic, Shure, B&O, a few others I'm forgetting) have been gathering dust since the Airpods Pro came to market. I do not miss de-tangling the cables.

Of course, it is possible to do better, but not easy or inexpensive. On my desks at home and at the office are dedicated headphone rigs: DACs, amps, and wired open-backed cans (Focal, HifiMan). Those set-ups sound great--although not nearly so great as my two-channel speaker systems. But that's what it takes to get appreciably better sound than Apple's Bluetooth sets, and forget about portability.
