One cannot fit high end audio and processing hardware into a thin, light chassis and expect the device to run the entire day. Hopefully, the Oppo phone will be able to buck this trend, but that remains doubtful.
4. Alerts? With modern smartphones, those can be temporarily disabled or made only visible on the lock screen. Calls and other real time communicstions can be set to be temporarily ignored with user-controlled "do not disturb modes...
I find myself halving great difficulty in determining what the target market(s) for the X1 is is/are. As said above, the X1 will probably end up cannibalizing a good chunk of X3 sales. The X3, though popular with audiophiles, seems to be geared towards the "tech-literate" section of the mainstream. This group, which, for the most part, is fairly price conscientious, would jump at the chance to acquire a device with better fit/finish and near-par SQ with its higher end predecessor. There will, of course, be a significant jump in sales, but, without any idea of what your projected profit margins on the two devices are, any guesses made about the financial viability of the device would be...purely guesses
Those who already have an X3 would purchase the X1 in the following conditions:
Exercise use--assuming the consumer still wishes for premium audio whilst exercising
SO/family/friends--cheap player to give others the audiophile "bug"
Replacement--low cost alternative with most of the features and SQ of the previous model
Please note that my market experience is limited to the Western theater and that I cannot speak for what might occur in your home market of China. From what little I have gleaned from journal articles and your posts, the Chinese either want the best value for their money or the best at all...
