That is a shame, as I am finding out that IEM's are particularly much better at corrections with EQ, than normal headphones with single drivers..Shameless plug. Perfect condition Indigo's up for sale.

Once you have an IEM that has top resolve, then all you need is EQ to your preference, as no IEM is perfect in signature for everyone.
