Buttons too small, cord too short compared to its predecessor

so far I have the HBS 700, with which I am very satisfied. Now I've tried the 800 and am rather disappointed. I'll back him because he also seems still to have a defect (LED headlamp, even if it is off).

The control buttons are smaller than its predecessor, so I am doing it here difficult to feel. This is true even at the slide switch on or off.

Also, the cable seems to me shorter, definitely are the earplugs to find worse when wearing headphones as was the case with its predecessor.

From the ambient noise suppression that I could be touted on the packaging is not much perceive in bus and subway. It crossed my headphones before quieter than its predecessor.
