No, not true, they were already returned, I didn't care for their sound signature compared to any of my other Grados.
I preferred the RS1i/PS1K's far more for my tastes.
I do agree with you 100%…you should get what you are expecting/paying for. Grado did offer too gladly change the cable for me to 1/4" though.
I just pulled the trigger on some T1's tonight after reading impressions/reviews, sounds like I may like them, but of course need to hear them for myself.
It seems very hard for me to like the sound signature of other HP' I've tried compared to Grado's.
