A2Dp function on w580i

[senter]

EQ's dont work over bluetooth, A2DP sends over the music data, and lets the speakers determine the EQ settings itself ;)

Sorry, but you wrong!
On my K800 equalizer settings work on Stereo Bluetooth™ Headset HBH-DS980.
On Bluetooth speakers may be not, but on Stereo Bluetooth™ Headset - work!
