Heyo!
To be honest I created account just to write in this topic.
I see so many people are frustrated with MTW3 (just go to reddit...) and I can't blame them!
I could call myself some kind of Sennheiser Evangelist - I convinced few friends to go with MTW 2 instead of other options.
I was always honest - "you can't find better sound in TW earphones, but UX is... not great, but at the end of the day, it isn't terrible also (although rather bellow average in this price).
What was sad is that 2 of them had to bring earphones to repair, because they broke (didn't have problems with mine tho... but lost them in the airplane ;().
I had MTW2 since the beginning and it took like 2-3 months for them to work properly - as Senneheiser fan I was treated as a fool, or simply - a beta tester.
Nevertheless I knew that I will buy MTW3 because of multipoint and the fact that music quality is the most important part for me...
Learned by previous "beta testing" I decided that I will wait ~3 months before buying new earphones...
Unfortunately, as I already mentioned, I've lost them in the airplane and had to buy new ones at the premiere.
Despite what other people say - they were working better than MTW2 (comparing to young ones), although still were extremely buggy. Most critical bugs were resolved faster than in MTW2... but we didn't have any info about multipoint or any other upgrades - f.e. we have "adaptive" ANC, but we have to change setting when it's windy (What - it's adversity of being adaptive!).
I understand that you aren't able to share when we can expect multipoint - but from our perspective - fans, who trusted Sennheiser and bought "fresh" MTW3 despite bad press, it's really crappy. It's really crappy how we are treated. We should be notified when we can expect it, what you are working on right now - or do you even hear and understand our pain and trying to solve those issues.
I will stick to Sennheiser because I love the sound... but I won't be able to recommend your products to anyone anymore and you aren't doing anything to change it.
Fun fact: in my MTW3 wireless charging doesn't work since the beginning
When I put them at MagSafe, diode flashes for a while (something like 1m), makes strange sounds, and charging is turned off completely). Off course I should send them for the repair - but c'mon - I need them on daily basis and can't wait weeks before they come back to me :/.
