Started with Flightcom (functional), moved to David Clarke (comfortable), bought Bose (lightweight & comfortable with ANR) and never looked back (my backup set is David Clarke). Most of the aircraft I fly have Bose included!
They are more expensive and they are a little delicate, but the warranty is good. Haven't tried the Zulus and can't see the point of mp3 jack on the headset. If you want music get a decent audio panel and have it piped front and rear, so that it can be isolated to pax only or fades out when you transmit.
I always carry pack of spare batteries in my flight bag and swap them when they start flashing Orange - I know they will go longer, but the green flashing is more calming
