Is the Key2 earpiece maximum call volume louder than on KEYone? I could use a louder earpiece, as it's sometimes hard to hear my callers in loud environments using my K1.

As a K1 user I am also interested in this. In a noisy environment such as walking outside in the city, it is very difficult to hear.

Using a pair of in-ear 1 more triple Driver headset and it is painful to listen at the full volume. I can also decently pilot the Sennheiser HD 800 S and we are talking about 300 Ω impedance...

Anybody have any input on this question?

I have input. Just gave up the KEYone for a KEY2 and both ear piece and speaker phone volume are noticeably better.
