Pros: small, sensitive light and good sound proofing
Cons: overwhelming character
I have Grado SR60, SR225i, HD650 and HD25 II's, with an iBasso headphone amplifier, fed by an ipod dock cable. I principally bought the HD25's as a monitor headphone for video use but thought I would burn them in for 100 hours and see what they do with music. The reproduction is not what one would call subtle, the extreme frequencies are pronounced and there is little impression of ambience or imaging. It is like it is trying too hard to please. I can imagine, for that reason, it suits loud rock music, but it tramples delicate good recordings. The cable picks up some microphony.
