U12t V1

I was worried a universal shell wouldn't seal as well as my old customs, but these sit flush and the isolation is genuinely impressive on flights. The low end digs deep without smearing the mids. Two months in and I'm still noticing little details in tracks I've heard a hundred times.

The universal fit actually stays put during long walks, which I didn't expect from a non-custom shell. Detail retrieval is genuinely impressive for something I can just pull out and wear without an appointment.

Swapping between the included modules actually changes the bass response noticeably, which I didn't expect from a universal fit. The shells sit deep enough that I can wear them for a full workday without fatigue.
