The Sony - nice and high quality packaged - can score in almost all areas: very pleasant and solid but not disturbing seat, almost no heat generation between pads and ear, even at high volumes clear highs, clear mids and accented ........ ............. so where was he now, the extra bass ??? Forget install ??? Overlooked activation switch ??? Inserting batteries ???
No, simply does not exist. What is referred to herein as "extra bass", are at best deep middle, a short drier bass is definitely absent.
In addition, the headphones starts with increasing volume at the bottom (I deliberately say no bass) on to boom, so that even with missing lower frequencies remains of listening pleasure on the track.
I do not know how he gives himself in MP3 and Ipod Gequetsche Preserve. I hear CDs - without exception first editions without digital remastering - over a conventional analog Denon amplifier and a Harman Kardon BD player, who also serves as acoustic setter over all doubt thanks Burr Brown chip. Only at these almost unadulterated sound, a headphone mE show what it can do.
And in this Sony unfortunately infected not what is promised or advertised: Bass, Bass and Bass again.
Maybe he could convince classical music fans, because since the bass plays surely not necessarily the tune :)
My conclusion: total for the price acceptable and quite Swimming along the broad middle group of competitors - but nothing more.
And extra bass already absolutely not !!!
