My feelings about the IE80 and cables.The stock cable is garbage.The plastic sheathing is too brittle and cracks around the join with the earphone units.The IE8 cable is far better,a much softer plastic and much more durable.I now have two Forza Audioworks cables.A copper and a copper silver hybrid.Both have different sound signatures as one might expect,but both make a huge difference to the sound.I really was quite shocked when I first heard the difference.They are also extremely well made,so should easily stand up to extensive mobile use.In fact,my son is using the copper one,and he's a cable destroyer! It's still going strong,testimony indeed!
Incidentally,the IE80s scale really well.I use mine at home with a Chord DAC and full size headphone amp.I like what I read about the IE80S,it sounds as if the slight "rough edges" on the IE80 have been effectively smoothed.I am intrigued by other DD iems out there,in particular the Campfire Vega.At four times the price of the Senns,would they really be so much better?
