I've been looking at trying to get a good deal on Sennheiser Momentums recently as I am only able to spend £150 max (most likely second hand) but really would love these headphones. I have just found these on Ebay:  ...

I am currently looking at the on ear and over ear versions of the Sennheiser Momentum but cannot decide between the two models. I suppose the over ears are superior in SQ due to their price, but from what I've read the on ears are more bass heavy with recessed mids as opposed to the over ears...
