Loud crack in the earpiece

(+) The optics of the PRO200 I find quite appealing, also the haptics.

(O) The contrast of the display is very small when viewed from the side, but is not a big problem, since one the PRO200 the right angle can keep his nose up. Then everything is clearly visible.

(O) However, the phone went on the noise floor described in many reviews, but was also not an exclusion criterion for me.

(-) Battery charging time is very long.

(-) Has, however, what meant that I have returned the PRO200 again is that is a cracking irregularly loud noise often heard in the earpiece (or when you turn the speaker in the speaker). This is very uncomfortable. The phone will be unusable in my eyes.

Exchanges and refunds by Amazon was quick and easy, for kudos.
