Battery Time: I used them for 6-7 hours continuous alternating between music and voice with ANC ON before they hit low battery. CON - where did they all disappear to?Sizing: My feet are size 37. ac7354 Ive taken this time to just go through the calibration and finding that some of the buttons require a harder press to activate. I spent some time with co-workers comparing what I sound like using my Q20 versus my Q30, and they all told me I sound like Im "in a box" when using my Q30s. ac7354 may be use a bigger bolt ac7354 I do not recommend this product for shoe storage. This was because I intended them for garden wear and for use with thick socks. They are very light and comfortable to wear for long periods and the very generous cable length allows you to be well away from the sound source. ac7354 The mic sounds clear and the audio is great too.
