Sennheiser HD2.30?

I just got these on sale on Newegg for $25. They sound, to my ear, extraordinary for the price. It even has a locking 2.5mm, which for this price is kinda great. The low end is very AKG like, weirdly enough. The highs have the potential to get over whelmed, but the majority of the listening I’ve done it hasn’t been a problem. Does anybody else have these, I have seen little to nothing on them online and it looks like Sennheiser is clearing stock?
