After having the "Philips SHE9005A / 10" for a few days and have return due to a malfunction of the volume control (see notice on its description page) I am completely satisfied with this latest product. The gap between the supposedly 17Hz and 6Hz for "Philips SHE9005A / 00" remains imperceptible! The order volume one button works great! The sound is okay! Very nice design!
