Good balance 4

Audio:
+ Good rendered clear enough. The bass is actually quite present. Personally satisfied.
- We continuously hear a small sound in acute background, nothing embarrassing listening. Saturates when you turn up the volume, I have still never had a problem at parties about ten people.

Appearance, ergonomics, use:
+ A really looks solid and does not fear too much water, use close to the shower without any problems. Greater autonomy. Right size, neither too big nor too small.
- Reversed volume buttons (leftmost less right). cache connectivity impractical to handle.

Bluetooth:
- Few reach, often has trouble connecting. Although not as reliable as my old helmet airwaves but quality better reception when the connection is made.
This is in my opinion the priority area for improvement.
