Frankly - I don't use a Bluetooth-capable device for listening on the go, so no wireless headset/earbuds/etc. - near or total - is useful to me. Why, you ask? Because with my "old school" Sansa Clip+, I have tactile controls that I can use without even looking at the player - not the case for my touch-screen phone.
I AM very glad to see you've included a transparent mode for when people need to hear what's going on around them - this is a feature that's LONG overdue and should be absolutely standard.
