Thanks Dnalekaw, I'll try covering it with blu tack, hopefully it will bring the balance 

I received today a T50RP.
I always wanted to have a planar and Amazon had one at 89€
I should receive the Shure 1540 ear pads tomorrow (and some mad dogs knock off from China in a month or so).
So far I love the details, totally another thing compared to my Sennheiser HD600, but I couldn't pick neither one as THE best, they are differently very good.
the HD58X looks pretty interesting, and that 160$ price!well said mate, I feel the same way about those two headphones. neither is better. they are just good in different ways. I often find that planar in general just has this smooth sound to it that dynamic can not replicate. my current favorite headphones though are HD58X
