What sources are you plugging the headphones into?
The Sony MDR-V6 is very slightly less bright then the MDR-7506.
I am primarily using these from my digital Piano - a Kawai ES7.
Very strange what i hear from different headphones from the piano -
1. Soundmagic hp150- Very muddy in the lows, no clarity in the trebles and piano seems to be unnaturally wide - almost like the bass is panned hard left in the left ear and trebles are panned hard right. These sound fabulous with music though coming through my ipod with just a little bit of an exaggerated bass.
2. Audio technica M50x - Clears up a little bit in the bass, but still does not sound natural. Mids sounds a little boxy or nasal-y, and the trebles sounds beautiful. I notice through my ipod - it sounds just about the same with a bit of heavy bass.
3. Sony MDR-7506 - Bass sound extremely clear, could use a little more oomph in the bass, but could live with it as-is - the trebles and mids are almost painful to listen to for a long period of time. They are just way to bright with the piano.
4. Sennhesier HD-650 - VERY muddy bottom end and mids, the upper end sounds pretty nice through these headphones if not a little mellow.
Now the odd thing is, if I make a recording of the piano and play it back on any other source, teh rrecording sounds beautiful. The recording is being made directly on the piano to a USB drive as a wave file, so no additional processing is being applied and no extra devices are in the chain.
I play the files back on any of my devices, ipod, ipad, mac pro, etc, and listen with any of these headphones and it sounds great. the muddy bass seems to go away.
So I am assuming it is something within the ampliifcation of the piano.I need to find a good combo for this device.
i am wondering if I can find a happy medium headphone that has the bass of the mdr7506 with the highs slightly toned down.
Someone at a guitar center recommended m40x as a more neutral sound, but the highs may be just as irritating to me as the 7506....
Any other recomendations?
