That ethereal sound is what electrostats are known for. Some call it 'sound coming out of nowhere, effortlessly' and some call it an unnatural lack of body. Personally I'm a fan of it even for rock and metal. It allows me to listen to badly mastered recordings without having to chase down a dark or warm sounding headphone(a signature of which I'm not a fan of) A lot of people talk about the lack of impact to the bass, but few talk about it's effects on the mid-range and higher frequencies.
It's all about what you are looking for when auditioning a headphone and the things that are an immediate turn of for you. The sooner you figure out what you're looking for and your pet peeves, the better. Personally for me I need a coherent sound where I can follow the drums, bass lines, and feel the emotion behind the vocals. And I can't stand what some call 'richness' and 'warmth'. I also can't stand headphones that are too unforgiving of the source material. And for me that means stats(and possible orthos, haven't tried them yet). Everything has a compromise, it's a matter of finding which compromises you aren't willing to make.
