That sounds good to me. I think Sennheiser's idea of loaning out their headphones to some Head-Fi'ers was great. I admire them for letting us try them. I think the combination of reviews by different Head-Fi'ers ultimately provides a pretty fair and unbiased evaluation of the product. It's never wise to trust just one opinion, but the combination of opinions by different Head-Fi'ers eventually presents something very close to the truth. I admire Sennheiser for letting us run the HD 215's through the Head-Fi wringer!
As long as they send them to you guys who have heard the other Sennheisers and have a point of reference. Then it is easier to spot the differences and improvements.
