TTVJ slim would be an excellent choice for the genre of music you listen to. Really does
well with vocals. I'm having traders remorse in letting mine ggo but find the arrow 3G mmore well suited for what I listen to (including classical, but more bass heavy music like soul/hip hop/reggae/dancehall. I use them with silver recabled er4p by chris_himself so the darker sound of the 3G meshes will with them (I know bass and er4ps sounds wierd but with the arrow bass boost and silver Recable, it does wonders for the bass and lower mids and even the sparkly highs - making them an awesome choice for versatility and portability).
There's a slim with dac for a great price on the boards right now. I'd jump on that but trying to think as a minimalist right now =P. Battery life on the slim is awesome! The bright light is kind of annoying but def not a deal breaker considering how well they do sound with jazz, vocals, and classical.
