Your FXA7 seem to function normally, this is exactly how I remember from along demo in Singapore when compared to ASG2.0/2.5.
Bass is less present, which was disappointing coming from a long series of bass-heavy ASGs...
And upper mids felt recessed, which was also a departure from all ASGs.
In terms of treble, I don't remember a large difference, but since I don't have my ASGs anymore, I can't compare again.
If you add the lesser built quality, it was really disappointing.
SureSeal tips had very polar reviews: some people love how they stick into ear canals, but others like me hate them because they're earwax magnets and get dirty very fast.
Yeah, the SureSeal tips are dirt magnets. Not only attracting ear wax but also other things.
I wouldn’t say the FXA7 is dissapointing though, cuz in the end they aimed to deliver an IEM that’s different in tuning with the ASG and the Kicker series. One thing that FXA7 does better than the ASG 2.0 is that the sub bass is more noticeable than it is on the 2.0. Though odd enough the 2.0 felt smaller in my ears than the FXA7, perhaps because of the eartips I use.
