Got a pair of A151P. Immediate comparison with my Beyerdynamix DTX 102 is the lack of punchy bass. The bass is there but is not prominent or emphasized. Definitely not a basshead's pair of in-ears. I would say vocals are emphasized, and it tends to block out some of the instrumentals. With the Beyers I could definitely pick out more instruments behind the vocals. For the price of the drop these are quite good, but I wouldn't pay the full msrp for these.
