I have both the LPs and ATH-M50. I find the ATH-M50 more comfortable. The LPs just clamp too much to the point that I cannot wear it longer than an hour without needing to take them off for a few minutes. I've been trying to stretch out the headband to relieve some clamping but not much...

I'm so glad to be broke right now even though I really want to test these out badly. It'll give me time to read some reviews before my finances are replenished.

Just curious, has anyone ever tried coupling this with a Fiio e11 as a preamp? 

I've been keeping tabs on this thread quit constantly. I haven't been so eager for a product in a while!

Seems like a great price at $80. I've been reading up a lot on the ZO for a while now (about a month or so) and was luckily to read up about the upcoming v2 release before I bit on purchasing the first model. I hope this is worth it!

I don't have the E11, but I have the E5. The red light turns off after fully charged. The same might apply to the E11.

Does anyone have an opinion on coupling an E11 with an HD-25 or Brainwavz M2 versus coupling them with an E5? Sorry for my ignorance if anything similar has already been answered.
