It charges my phone quickly and the cord length makes it that it can still reach my cell phone holder. I walk a lot in the desert (Im a field geologist) and during my work, fine sand had filtered down through the mesh uppers, worked its way down the side between the outer part and the goretex liner, and filled that little pocket below my toe. Great for walking. In this recording when I was trying to play music while using the video camera on my phone, pressing the volume button ended then restarted video recording, which is why I had to patch it, and the volume buttons didnt work well with the music. I have tiny ear canals (apparently) and these don?t hurt plus they stay on. A representative from Rockdove contacted me and immediately said that they would correct the situation. Also required a firmware update using Jabra Direct. Nice packing and product working properly. I?m only rating 4 not 5 because I eventually did have to take them off Unfortunately, the latest batch is a completely different product.
