I have a little bedroom-studio mixing/recording my music, with a pair of Fostex PM0.5 as my near field monitor, and an AKG K240s for some more detailed recording. I mainly do synthesizer and electric guitar recording. Recently, I feel like I need a closed back headphone to clear out some noise direct from my heating system (which is a consistent bass humming). Also, for some reason, I think the K240s provides a lot of well balanced details, but was not able to stands out the treble and bass correctly (while recording). I mean, they are perfect when I use it to mix, but the characteristic of the sound biased compare to the segments I recorded with my PM0.5. I know that doesn't even make sense, but that bothers me and I cannot use my K240s to create a more accurate recording for the very same reason. So I'm basically looking for something,
1. Around $200, I don't mind to buy something less than $100, but not looking for something more than $300
2. Closed back
3. Mainly for recording/tracking, I don't ask for a well-balanced or neutral headphone for mixing. But looking for a headphone that stands out every single frequency. I want bass, treble, and mid. If the frequency is a little biased, it's fine.
4. work okay without a stellar DAC or amp
Some closed back I tried:
Beyerdynamic DT770: I like the dry and tight treble and mid, but not sure if he got enough detail
ATH M50: A little bit muddy, I tried some ATHs and most of them get a similar impression for me
Sony MDR7506: I was sort of overwhelmed by the mid, but this one were actually close to what I was thinking about, but totally not impressed with the details.
The one I absolutely don't want is something like K601. It's a wonderful headphone, but I had a hard time with the spacey sound without a proper amp.
Any ideas? Thanks in advance
