HD-662 F : Less treble harshness

Bought these for tracking vocals as they are closed and for mixing activities due to their flatter EQ curve.

I own the cheaper and highly acclaimed Superlux HD-681which are good for tracking instruments like electric guitar, bass, electric drums, electric piano/keyboards and general listening purposes, but as many have stated they have over-pronounced and harsh high end frequencies (Treble) which renders them almost unusable for mixing.

The Superlux HD-662 F sound very different from the HD-681, treble is present but not so over-pronounced and harsh and the mid range is more present, lows are there but in a more rounded way. The overall volume output seems to be lower than on the HD-681(maybe due to the lower and less harsh treble).

As the manufacturer states the F stands for FRONT not FLAT as many seem to think, these headphones are less "inside the mix" and rather in front of it indeed, which makes them more suitable for mixing. I have not tried the B models, but based on my experience on the standard series and the F i would recommend the F series for anyone who is planing to use these headphones in a home studio and the standard series ie. HD-681/HD-662 for music listening and tracking(recording electric instruments) since they have more low and high end dynamics than the F series.

I will not comment on comfort since that is up to individual taste, for me these are OK.

All in all i really like what Superlux has been offering at such low prices compared to the name brands!
