They certainly can accentuate the highs that already exist, making it sound fizzier.Headphones won't add fizz to the sound unless they're being overdriven hard enough that they're distorting. What 'phones are you using?
If you use headphones often I would recommend getting a Neve RNHP headphone amp for the AxeFx III. They'll make a cheaper pair of cans sound like a much higher quality pair. To me the amp is more important than the headphones themselves.
That's what I like about them, they don't sound as closed in as closed back headphones. The sound breathes a little more for to the open back. I don't think you lose anything other then a touch off bad responseIsn't there a lot of leakage from HD600s or their Drop version? Besides DI electric, I also record acoustic and vocals, need phones with decent isolation.
Currently using AKG D240s. Not unhappy with them, and I've had them for years so I'm pretty used to them, but I suspect strongly they're cushier on the bottom rather than more neutral.
Same, go for these! Identical to the HD650 (minus very minor aesthetic changes) but 1/3 the price.HD6xx from mass drop just received recently. I never liked cans before but these are really great. I can plug them into my iPad and sounds great as well.
I barely turn the volume on and my headphones are blasting, so I’m not worried about loss of volume. What I want is a more balanced tone. My ATH-30xs sound just fine everywhere I else I try them - Apollo interface, Samsung phone, Hotone Ampero, even my little MP3 player. Plenty of low end. They sound harsh and brittle on the AF3. To me that is very confusing, because everything about this unit is audiophile quality.The higher the resistance, the harder they have to be driven to achieve a certain volume.
