Headphones (almost) perfect

I use these headphones for over a month, here is what comes out of my use:
The strong points:
+ Great design (ie staff)
+ Excellent build quality, materials exude quality.
+ The features galore, handy
+ A very good ergonomics
+ The combination of passive and active insulation, excellent!

And now, what angers: areas for improvement:
- Autonomy remains quite low compared to competition, although this is understandable in relation to the proposed functionality.
- The absence of aptX codec lorsque'on degrades the audio quality used wirelessly with an Android phone (or other non-Apple device): compression artifact are audible on a helmet at this price I think it unacceptable! It's a shame because this helmet could have been almost perfect.
