I'm pretty new to this so apologies if my vocabulary is lacking when it comes to describing sound...
My PM-3s arrived yesterday & I was really excited to get them onto my head. I plugged them into my ALO Intl+, hit play on my phone &... was disappointed. The mids sounded muffled - drums & guitars were distant & washed out. Every change-up came & went without any satisfying punch. My girlfriend tried them & said, “yeah, something’s missing.” Switching back to my old Sennheiser HD25s left me bummed out. My £120 headphones sounded much better. I got the same result when plugging them directly into my laptop.
I started messing with the EQ & found that if I pulled it down by 6db at 500hz & then gradually pushed the treble & bass up to +6db (forming a 'V'), the PM-3s sounded a lot better. Toggling the EQ on & off sounds almost like dunking my head underwater…
Does what I'm describing sound normal? Is that an acceptable amount of EQ'ing to get something to sound good? I feel strange about having to tweak the sound so hard before getting a favourable result. Is there any chance that they might be defective? Or is this just the sound signature of planar mags? Will burn-in help with the mid section?
Any thoughts would be appreciated. Big thanks in advance!
