Sorry but there are something need to be clarified.
1, Usually we will make 100~200 before the mass production , and this batch is used to do some quality testing and also sent to some users/reviewers to get some feedback so we can improve the design and fix some bugs before mass production.
2, Usually we will make thousands in the first batch , it is not for test cause we will lost lots of money if there are any quality issues which can't accept.
3, The main reason why it is only for sale in China is there are huge different between China and outside China in the firmware, for example, in China no one care about the Googly play and we use different Apps, so it is more easy to us to sell in China first.
4, Please remember that we are a Chinese brand and it is more logic to sell in China first. and usually the first batch can't fulfill the market demand.
5, The reason we put some on Aliexpress is because some head-fi'er are eager to try it first, and they have more experience than other people , and they care about the sound quality than
the firmware issues .
of course, we will not encourage that everyone to buy the M11, we just provide it to you and you decide whether you should.
