Thanks for the detailed explanation. I eventually went for the Air2. After 2 days of use, my thoughts:
Pros: good sound quality, fit is good due to buds of various sizes, call quality is ok, good aesthetics, great value for relatively low cost
Cons: reconnectivity is clunky as sometimes the left earbud will have no sound. Ease of connection not as seamless as Sony wh1000. Charging case feels filmsy and cheap. The cover feels like it is going to snap off anytime.
All in all, happy with my purchase with outlay of $100
That's the connectivity you get from qualcomm tws+. Its driving me crazy, especially if you are a person who connects and switches between multiple devices. Sometimes there is lag in connecting, sometimes only one side have sound, and worst, sometimes it won't connect and erases your earbuds' bluetooth profile from your device.
I am trying to get rid of the tws+ earbuds I owned. Already sold off sabbat e12 ultra, next to go is soundpeats truedots. (Truedots is has high value-to-features worth, but tws+ killed it)
In my opinion:
Double master/mirroring > Tws+ > Master/slave config
Qualcomm's new chips, announced earlier, will feature mirroring, making connection more seamless in the new earbuds which uses them.
