These are my go to headphones. I used to use a variety of Sennheiser headphones, and before them some Sony’s. They were all really good.
However the microphones on them were a bit pants. Sound quality excellent, voice controls and responses not so good.
So I turned it all on it’s head and bought a pair of these having used some pretty chunky Plantronics headsets at various companies for DECADES!
I was really surprised at how well these worked. Weirdly, once the rubbery coating matches your body temperature you don’t really feel them on.
The button controls work well, I regularly use next track (double click/left), volume down (hold left upper), volume up (tap left upper), check charge (tap right upper), power off (hold upper right) and Siri (Hold right).
I’ve also used it for dictating FB and WhatsApp messages.
I’ve owned these now for 10 months and they’re still going strong and the batteries are still lasting as long as when I first got them.
The only real complaint might be that they can sometimes be a little quiet - but this is only a real problem when there’s a lot of background noise (MX5 with the hood down, busy train etc.)
