I've had both the Sabre and the Mee Audio P1 (the reg version not Massdrop though I think they're sound sig is pretty much the same) and ajaxender is right. The Sabre are quite vivid-actually too vivid for my tastes. They are quite hot for me in the high mids/lower treble and accentuated sibilance (I'll admit I am pretty treble sensitive). The filters only changed the bass quantity. the P1's were not as bass heavy but bass is still certainly present. The treble was tamed a bit vs the Sabre's but still very clear but not harsh like the Sabres were to me. The big thing I also found was the soundstage. The P1's have a great soundstage and is imaging is great. Really has this cool 3d like quality to it (great sense of depth). Sadly I had to return those also because I have a terrible time getting in earphones to fit as I'm usually that one guy that has fit issues . Almost everyone else I've read about that has tried these love the comfort it seems including one of my friend's who has a pair and loves the comfort and sound.
