HiFiMan HE560 or HE400i?

And what about the highs?
Is not a worst choice regarding the highs?

Thanks for your advice!

 

I own both the 400i and the HD650, I would definitely not say you are downgrading when going to the treble on the HD650.
Though I may be biased, as I am not a huge treble head, and generally like my HD650s over my 400i's in almost all situations.

You are probably more likely to get peoples impressions comparing the two if you post the question in the general advice thread.
