I listen to metal primarily, and I've extensively listened to all three 381 variants. The 318F is the best for metal, it has the most space/air with just the right amount of bass that for double bass assault IMO.
Incidentally, you can audition the three variants all you want either at Egghead Robinsons Galleria or at Cutting Edge Gilmore, so you can decide for yourself on which one would suit your preferences best (I'm assuming you live in Metro Manila).

















I have conversed with you also in some threads in headphiles.. Thank you for that insight. Unfortunately im from Laguna i rly want to visit Egghead sometime.. In the meantime, can you tell me the sound sig of the 381? and the 381b? Im confused right now because some like the 381b, some like the 381, but most prefer the 381f.. they said the 381f is mid centric and good for vocals but may be harsh or bright. the said the 381b lack bass but is good in highs. and the 381 is the most bassy.
