Eargasmic vocals too.
Head-Fiers shouldn't be hatin' on XBA-4, they are incredible IEMs if you can handle high energy treble and dynamics...
Sort of like a mix of qualities of TF10, CK10, and IE80/FX700 but with a sparkly/metallic treble.
Vaguely reminds me of Klipsch S4 treble, sometimes. I might be wrong, I havent heard the S4 in a while.
Definitely like the XBA-4 more than the EX1000!
