I have placed the Grado RS1i and RS2i on my shortlist as a replacement for my Sennheiser PXC300 headphones for classical music, since I like a clear, bright and sparkly sound for classical and it looks like these Grados may deliver in that respect.
I hav, however, health issues that make headphones difficult to wear long term and thus I may not be able to determine long term comfort prospects from an audition in a shop. Apart from neck problems (which preclude heavy headphones) I have TMJ (temporomandibular disorder) problems on my right side - probably a legacy of many years of violin playing - and I cannot take a sustained pressure on that right side joint without getting it aggravated. You read up on TMJ here:
This is why the PXC300 have been great headphones, since all the pressure is only on the ear itself (and very light at that). Although the Grados are supra-aural, it looks to me as if the cushion size is quite a bit larger than that of the PXC300 and I suspect the pressure would be higher as well.
I was thus hoping if someone could measure the standard diameter of the cushions on the RS1i or RS2i and let me know what it is please? Also, do you feel the Grado puts pressure on the jaw joint (refer website above) or is it mainly on the ear only?
