I don't have the BT20s, but I do have the P2s -- I've never been that impressed with them and they quickly fell out of rotation. They are nowhere near the capability of the P1s/PXs, which I adore and still listen to. I think that contributed to my take on them -- I kept comparing them to the P1s, which they're not (but they also cost a fraction of the price, especially with that deal).Anyone used the MEE AUDIO PINNACLE P2 with the BT20/s? Drop has it for $25. I remember looking at these before I bought my iBasso It01's and they were similarly priced.
But for $25, it might just be worth a try. They aren't overly sensitive, so they shouldn't hiss much, and they don't take much power to drive well (unlike the P1s, where more is better). I'm a little surprised they're blowing out the stock -- I wonder if MEE has something else in the works or if they're just trying to shrink the product line. If you do buy them, do yourself a favor and throw the stock cable in the trash straight away.
