Yup, could be his early work, doing variations on Fenders maybe, but seems he's gone much further upmarket now. Still, yours still sounds like a real bargain from a quality builder
Yep, it's a nice touch having the units sort frequency. The one thing that the Xvives have that i really like is that they're angle adjustable. Useful if you have different jack mounts. Also a 20ft range advantage over the Boss, but that's not a big deal
No problems with mine, either latency or quality. Had them a couple of years now. Yes, always take spare cables, but you'd do that even if you didnt use Xvives. I only charge mine the night before or the same day, depending
I use Xvives, and love them. Dont think mine are U2 model, but regardless, they're really convenient. I get 3-3.5 hours from a charge, which is enough for most gigs
