OK guys, I've been searching a bit on the net, but I wanted direct opinion from trusted, veteran audiophiles that I can find here. For about a year or two, I have had a bit of a problem, feeling unfocused, sometimes unstable, but it culminated during last october when I had an vertigo attack (if I can call it that way) where I couldn't move and felt I will black out. Since that I felt pretty dizzy, I went to a doctor and aparently everything is good, they suggest it's anxiety problem, and that very well might be the case, since I had problems with it in the past (something similar happened to me during the extremely stressful finals year before that), but since I feel no transparent anxiety, I was wondering could headphones produce something like that? Can they make you feel unstable, unfocused and dizzy? In last 4.5 years I've been using headphones a looot, I've been living in small apartments, where neighbours can hear everything, so I use them literally whole day, from time to time I turn my speakers on quietly, when I want to rest my ears. If you have similar expiriences, or suggestions, feel free to post. Thank you.
