What would I do with a total of 4 S400s?
I've paid over 250$ for the ES700+WS55 pads, 3 23$ phones won't cut it...
Would trade it for T-PEOS H-200 or ATH-CKS1000
The looks of ES-700 are far ahead of its sound. I really tried to like this phone, and for a while I did - until HA-S400 suddenly turned into a completely different phone after burning it with this:

Burning it with music for 200 hours didn't do much, but this noise really made a huge change.
ES700 is a decent phone, and if I would have paid 95$ for it (current price in Japan), I wouldn't be so disappointed in it.
It is a good ~100$ phone, but no giant killer. No one is going to pick them over Sennheiser Amperior.
