I mainly use the AKG 518 for editing stuff, it's not reference i know but price-wise, portability and its closed back design keeps all the other sounds at bay.
The Marshall Major sounds okay too for it's price, plus it's a bit cooler looking (better sounding) than the beats IMO.
I liked my Bose triport acoustic in-ear, highs sound nice and clear and bass is just enough not to make it sound muddy, comfortable too. But I find that I need to pump the volume louder since they're not the sound-isolating type.
To the thread starter: since you've been using Sony, have you considered the MDR7506? It's what we use for field sound, pretty decent for it's price compared to the more 'professional' ones.
