Headset test: Razer / AKG / Jabra / Sennheiser for Android + Fritz Fon + PC!

Having nowhere I found a reasonable test, I've made it by myself a little more effort. My for purpose of: an affordable headset that lets you make calls in good quality with Friz Fon C4, Android cell phone (Samsung Galaxy Note 3) and the PC with Skype or Dragon NaturallySpeaking dictation and listen to music on the go reasonably can. The Diktierqualität I tested the Samsung own Dictaphone app. All without scientific claim, but maybe for one or two helpful. Candidates: Razer Kraken Pro (72) AKG K 452 (89), Jabra Revo Corded (58), Sennheiser HD 219 S (64)
