Yeah, thanks. But back to the question. After how long did you get first effects?

oh really? so that's defenetly a must have one for me.

Thanks a lot! My Sennheiser HD201 are only 21-18000 Hz, but they're I-doser approved, so they should be ok. Then I've tested only strong doses because I didn't know that mild are better for beggining.

Hello, I'd realy liked feeling of no gravitation. Is possible to experince this with I-doser?

Hello, I know that there's people who gets effects of I-doser after first use (even with low quality earbuds). But I've listened doses many times without effects, or with very poor effect.
So my question is: After how long are you getting first satisfacfing effects?
