I am not sure if there will any more drops with this in ears, but i will leave my impressions, maybe somebody will find it usefull.
The package arrived today, and i think these are quite good iem, through i am not quite sure.
The quality of the build is very good, there are no problems like mentioned before. They look great and are comfortable.
But, the first hearing isnt so great until now. The bass is really nice and quite powerfull and the iems sound very clear and detailed, but i really miss the high parts. Like they were cut out or reduced to 50 percent.
I will burn them in for some hours and look if it gets better.
Yeah it helped, they are really good now. The high frequency is here, but the real highlight is the bass of the iems. Really powerful und tight.
