I recorded a track with lots of reverb on the vocal, it sounds fine at a lower casual volume, but when i turn it up the reverb takes over everything. I recorded it with a tascam dp03sd portastudio and studio projects b1 condenser mic awhile back and i just found this out using my newly acquired sony mdr 7506 headphones. I dont hear this problem with commercial tracks such as the a team by ed sheeran or lump sum by bon iver. Is there a reason for this or is it normal?
