I had some air mile points I needed to use.  I was trying to decide between the PSB M4U 4 and the AKG N20 that were both offered through their rewards system.  Decided on the PSBs and ordered them last night.  This morning I see you posted a review.  I am hoping I won't find the mids too recessed.  My preference is towards a neutral sound signature but a little extra bass doesn't hurt.   Looking forward to getting these. The deciding point for me was that they are made by a Canadian company.
