I recently got a pair and for some reason I'm not able to activate Google Now/Assistant by long-pressing the middle button. All the other button-functions work though. Am I missing something, is this normal, or do I have a defective unit? I've paired it with an Xperia Z3 Compact running 6.0.1...

Did you get the Voskhod 6N23P tube with the amp or was that a separate purchase?   Also, how does it sound driving IEMs?

Looking for recommendations for IEMs after listening to the MS1is for quite some time. I like their sound but for fit, practicality, and portability reasons, I'm looking for something else to listen to from my laptop and my Galaxy Nexus (microphone/control is a bonus but not necessary).   My...
