I recently bought another (2nd hand) V30 for $260 and was stunned at the screen. My original V30 had a little off-angle blue hue, and some mild banding noticeable in low-lighting with the screen brightness all the way down. It's minor and never bothered me, but this newer V30 must have been from a later batch, because it's screen is absolutely perfect. A totally different product.
Most of my headphones have balanced 2.5 mm trrs connectors too. I regret that now, because most of the time I feel like a dumb Apple user with a dongle. Yes, there are many devices that offer more power via balanced connectors, but, if the OEMs do their single-ended output properly, 3.5mm trs is more than enough. The best-sounding, most powerful portable device I have is the Hugo 2 (single-ended output) and it's specs (including channel separation) poop all over anything I have with a balanced output. My best-sounding DAP - QP1R (single-ended output); my favorite ultra-portable DAP - Shanling M0 (single-ended output), and my phone - V30 (single-ended output). I doubt I'll buy another gadget with balanced output. I think what
@waveSounds means is a balanced output would likely kill LG's sales. Most people wouldn't be interested. I'm looking forward to the day I can re-terminate all my headphones to 3.5 mm
