I burned in and listened to Tingo TG-38s with 2 foams for more than 1 week, the sibilance is reduced, vocal is not as thin as before, but I don't like it more than Dasetn M1. Its extended and sparkling treble is fun to listen (and that's all good about it), especially guitar sound, and some vocal sounds crystal clear, but some high vocal can have sibilance. I still prefer M1, while sometimes take TG-38s out to try.
About soundstage and imaging, it is not as wide and deep as Havi B3.
I lent both over to my friend who has all Yuin and some Blox earbuds. He was not interested at all, stating that some fake Yuin can sound much better than those TG and M1.
I sold both and use Havi B3, there is no reason for me to keep them at all.
