pressure changes seemed to effect my ears no different using these compared to other headsets.
I really can’t tell you. I’ve always had a pretty active ear wax production ability. The CA MAY cause a problem but I’d never able to tell. I will say, I had earwax build up on the tips, but after a couple of weeks I’d stuff them in a sock and run them through the washer with my laundry. That cleaned them off pretty good and I’d get about a month and a half for one set of tips. Or there about.
No problems. The cord is long enough and I’d just run it under my right armpit. Easy enough. The only problem I had was it would sometimes get caught under the armrest when I raised it carelessly.
