I'm half-joking around, but I'm so hooked on the new sub-bass that I don't even want to let it go for a week. I wrote earlier that it was like a drug.
There are many songs on my portable device that I never heard on the stereo. I only heard them with earphones. So now (with the 846 and V4A), I'm going "DAMN", I don't know those notes were even in that song. Song after song, it's all new again.
