Vocals are more forward with the UE 900. The W4 should do better with vocs as it does the vocal range a little better. For female, the differences are small for the most part. Some lushness, which the 900s lack, can come into good use as well, the 4s do very well in that area as well. I feel the W4 is better with vocal range (height and depth). For jazz and rock, I'd go W4, for classical, the 900. Both can do them All pretty well though.
