Val,
I think it is amazing how receptive you are to direct feedback from your customers. I am not a pro or a dj, but I am a forty-something audio enthusiast who does most of his music listening during exercise on my Iphone. I mistakenly purchased $300 "rapper" headphones about 6 months ago that look great and are comfortable but are seriously disappointing regarding sound quality, particularly mids and highs. I have been searching for audiophile headphones made for portable use that, in addition to providing clear, spacious and accurate sound across the spectrum also provide deep, powerful bass to get the adrenaline going during workouts. This may be a loaded question, but should the M100 end my search? Also, regarding your Iphone headphone amp, will it be Iphone 5 compatible? I would rather have a premium driver that requires more power and use a portable headphone amp (using a Fiio E11 right now) than downgrading to a more efficient driver which may have slightly lower sound quality. From what I am reading, the M100 can potentially be competitive with Bose and PSB in addition to the celebrity endorsed headphones. I am really looking forward to trying them out.
