The saga began when I bought a pair of PL50s (used). Opened the box, plugged them in to my Clip+, and immediately concluded that I didn't like their sound signature. Too warm. (Vocals just sounded too.. echo-ey? flange-y? Don't know how to put it exactly, sorry..)
So anyway. I decided to play with the EQ to find out what it is about the signature that I don't like. So I switched to "Custom" EQ on my Clip+. It didn't do anything at first, until I turned up the treble ONE notch.
It made all the difference in the world.
The first thing that stroke me was that the volume was lower. And the vocals got more 'normal' and laid back. Just 'colder', somehow, and more flat.
It's not the kind of difference that one notch on the treble would achieve. I tried reducing the treble and making the EQ [seem] flat again, and back came the "Normal" sound signature (warm, flangey, echoey). Turned up the BASS, and the same effect was achieved.
Colder, less echo, less flange, more... flat...
(A little bit less detailed, though, but perhaps it's just because of the mids getting more laid back..)
I searched the web trying to confirm my findings, but all I could found was the issue about the decreasing volume, but no mention about the change in sound sig.
I tested using Hippo Shroom and VB, and got the same result.
After 10 minutes using the "one-notch-short-of-flat-Custom-EQ", switching the EQ back to Normal would make the sound insufferable to me. Too warm!
Anybody has the same experience, or at least could shed some light on the situation?
PS: It sucks knowing that EQ drains my battery..
