I've demoed both Sonys and IMO there is not a huge difference from the originals except for Android. The 1Z2 is still warm and syrupy, the 1A2 more dynamic, and between the 2 I think the 1A2 is the better buy.
That being said, the N8II is technically better than both. It has the wow factor (IMO) when you first listen and taking into consideration the price, sound signatures and true LO it's a no-brainer.
I also noted the main difference in new Sony units is Android but haven't listened to verify as you..
That is very disappointing, because the original units were gimped in both sound and volume output, wich "MrWalkman" works fixed.
So the new unit is basically still gimped in output.
Beautiful music were singing to me, and I went on with my daily business. The next thing I know is that my battery was down to 40%, which is my typical charging time.
This would be most logical, instead of waiting till 6, or zero.
In fact as I followed thread only one member had an issue.
This throws the past complaints to be possible human error..
As don't own this unit I have no reason either way to speculate, but I have tried it twice and it performed perfectly when I tried it.
Nice and warm but never hot.
So I am of the opinion nothing was ever wrong with charging. Only human error or abuse.
The hottest unit I owned was the ibasso 300MaxSS version, when I left it on while charging at same time.
The Ti version didn't get as hot.
My point is that the n8ii is even newer, more polished design tech, and so should at least be of same level of endurance.
Therefore, according to the law of averages, we should weigh in the actual number of problems. I can count at least two from the ibasso thread, and only one unit here.
This how we get the saying, " the squeaky wheel gets the oil".
Happens in every thread with new units. I post only because noticed it here.
Cayin shouldn't have to post any instructional about a battery topic gone overboard excessively by one or two members.
Just an eta on software update.
As with all other posts here, this is just IMHO, and nothing more.
