jrhodes445They sound really good. Clarity and balance with a tight controlled bass emphasis.
I prefer the Luxeover the Mee Audio PX and P2 I purchased from massdrop and my older set of Klipsch X11i which have a much stronger bass emphasis and lack the clarity and detail of the Luxe.
While they don't need an amp to sound good I primarily use the with my Earstudio ES100 Bluetooth DAC/Amp. It makes for a great potable set up.
