Is there a huge difference between UM3x and W4? I just received the UM3x and I felt the bass way stronger, prominent midrange and better soundstage ( feels wider, felt like I am immersed with music) More importantly, Um3x is way more detailed and it sings louder than W4 at the same volume...I felt the W4 sounds tinny and cold to me..I don't feel the "soundstage" as many head-fier says, "W4 feels like sitting at the 4th seat row in a concert". Don't tell me that my W4 got busted, as one of its driver breaks?
edit: has anyone felt that the W4 cabling got stiffer? I have owned W4 for 8 months, and this happens.
Do you mean the cable which goes straight in to the IEM ? mine yes due to the regular use (~2-4 hrs per day use since 6 months+).
