You need to specify far more criteria. Of course we want good sound but, like most people asking this question, you don't say where you intend to use them or what for.
I have Etymotic ER2XR, but if I never listened to music on the train I probably wouldn't own them.
I have Sennheiser HD6XX, but if I could only afford one pair of headphones for use inside and outside it definitely wouldn't be this.
I don't like the sweaty feeling of leather pads so won't buy headphones with these no matter how good they sound.
Shallow fit IEMs never stay in my ears so I won't buy them.
You see what I'm getting at? What are your preferences, what do you currently own, what are you going to use them for, what are your comfort needs? etc.
