Selling my brand new, just received Hisenior B8 with 16BAs (8BAs per side) and 4 crossovers. They come with a 1 year warrenty. Simply said, they sound wonderful. So wonderful in fact that I'll acquire the Hisenior T12, which is a lot more expensive though. These were my entry ticket into the BA only IEM world and for the price offered, you'll be hard-pressed to find anything better or similar. Also, they are handmade and were carefully tested before, so be assured that the driver matching is just excellent. This is my promise to you. There is no usual "HS" logo on the In-Ears which just adds to the aesthetics! Once you have them in your hands, lingering doubts about durability vanish and you can always safely put them away in the dedicated case.
