ALL that is as good as a single headphone driver as long as it is pouring into your ear. I see three mid/high range drivers and what appears to be a single low range driver. How is this 5.1 again?
I urge you not to fall for the surround crap with headphones. I have heard some of the most expensive ones (AKG Hearo 999 is in my personal collection) and none of them have impressed me. The AKG is passable but this is because of the amount of research they have with HRTFs which are used in the DSP.
I am sure, from your review, that you are happy with it - and I am not surprised. I have headphones that cost $1400.00 and I am still thrilled when I listen to my $30.00 Koss Porta Pro 2s
And Koss is amazing...I had the original Koss Portapro for nearly 2 years and then I sat on it
All Koss headphone have a lifetime warranty so I sent it to them and 10 days later I had a brand new Koss Portapro 2 with a letter of apology stating that they coundnt fix the one I sent in so they sent me its replacement.
Needless to say - I am happy.
If you are mildly tech oriented can you open up the base unit and make a few pictures and email them to me?
I will order one of these units for myself, open it up and clear up all these issues once and for all.
