Pros: Mids, Trebles
I (of course) agree with Skylab's review of these splendid 'ear-speakers'. I can also emphasize the power requirement in two words: "Speaker terminals".
I drive them from my 13W Ming Da integrated amp speaker terminals. Sublime. (I tried my Audio-gd Phoenix & LD Mk IV - just ok).
So highly recommended -if you have ample amps on tap.
