The pre-order of HE-560 is still being discussed internally and more details will be revealed soon.
A lot of ppl has asked how we tune the sound of HE-560 and HE-400. The benchmark for HE-560 is our very own HE-6. We wanted HE-560 to provide the same level of sound quality as HE-6 ( (being driven properly) while reducing weight, improving efficiency and a even lower price point. It's quality we really care about, not necessarily signature. Obviously we always prefer a sound that is neutral, transparent, slightly sweet in the mids, airy treble and tighter bass.
Same goes for HE-400i. We wanted it to provide the same level of sound quality as HE-500 while reducing weight, greatly improving efficiency and a even lower price point. We have done a lot of tweaks specifically to target the bass response.
