Can anyone explain why the EX800ST has the best bass with the vent taped, but the ASG2.5 has the best bass with bass port wide open?
Because without tape or something covering the vents you will not get much bass at all. You will get linear bass that extends low. Tape just gives it a lot more quantity.
This is what tape does to EX800ST/7550 from http://rinchoi.blogspot.com.au/2012/11/sony-mdr-7550.html
As for 2.5 I think anything more than 1/3 or 1/4 open will not result in more bass, only more mud and ruined mids. Fully open doesn't hit any harder than 1/4, you just get bad sound IMO. I love both IEM's.
