The Senn is a little warm for my taste, as well a peaky for certain frequencies.
The Grado is a bit too bright, even with MrSpeaker Doggie Treats.
 
I listen to mostly rock. These headphones are for work, so all I have there is my Mac into a Magni (I cannot have a DAC at work).
 
I'm looking for a fun sound, not too bright, not too warn
They also have to be very open. I need to be able to hear a knock on my door or the fire alarm or the phone.
 
Looking int he 300 range. Used at that price range is OK too.
 
Your help is appreciated.

Wasn't expecting someone I recognize!

 
I think a used HD 650 or (if you get lucky) HE400i provide a good balance of "not too bright, not too warm" you're looking for. How "fun" that is is subjective, though. For me, a "fun" headphone is more colored than those, particularly in terms of bass impact.

I think a 650 might be too warm for me, but I forgot about hifiman. Thanks.
