Are headphones becoming such big business that manufacturers just don't think it matters anymore? Numark, Ultrasone, and Etymotic have all switched to this relaxed 2dB threshold for channel balancing...and that's the models they actually ATTEMPT to choose match pairs. What? A decade ago it was common to match drivers within a half dB. I've had 4 headphones in the past year from various companies all arrive AT the 2dB threshold, including my repaired ER4S just fresh from Etymotic. This is really pissing me off. I wish it was just my hearing, but I flip flop the earcups/inserts and the imbalance moves with the phones, not my ears. My hearing is slightly, slightly to the right. Some of these cans are to the right 2dB, some are to the left. Do I have to start buying Sony pro and Koss exclusively, now?
