Great, but ...
This is a brilliant product:  lightweight, clever design, pretty flat attenuation.  The only issue I have with them is the mid-range cut seems a bit deeper than the rest, causing loss of bass definition.  For the price, these are incredible, don't hesitate to purchase them.  As a bass player, be aware of the loss of definition.  These are WAY less expensive than anything comparable.  Amazing.
