No issues at all, they fit flush to my ears, I have no sweat build-up ether, I know it’s gross, but some overheat my ears, but not the KS1 earphones.

The soundsatge here is wide, possible due to large shell or maybe large cavities for the DD drivers to breath? They’re also amazingly comfortable to use and even after wearing for several hours they’re still as comfortable as when you first inserted them.Remembering that these retail for less than 20 USD, we do have to temper our expectations accordingly. Nozzles have a forward and upward rake that helps with insertion depth and allows better isolation than the KS2 provided. The KBear logo is on the front of the shell with KBear KS1 and L/R marked in matching gray across the rear surface. The Aurora is the type of earphone that initially will not wow a person but the more and more you listen to them they will grow on a person as they have for me. The treble quantity relative to the midrange is somewhat high and Aurora has both ends uplifted above the mids, but the midrange isn't distant or too recessed, just moderately so with most music.

This being said the Aurora stays fairly safe with its harmon tuning and shows its strengths on a technical foundation for its sound. If you intend to mod the Blon BL-03 or the KB Ear KS1 it’s a much tougher fight with tone winning on the Blon BL-03, and detail winning out on the KB Ear KS1. The Ks1 follows a very similar pattern to the earlier KS2 I reviewed (at least on the exterior) with a 4 part shell made of white resin face and inner shell, clear plastic bi-pin housing, and brass nozzles.Translucent Resin Cavity Stylish Design】The cabinet cavity of KBEAR KS2 is made of imported high-density PC material which can well suppress the diffuse reflection of sound waves inside the cavity.

Again more wishful thinking on my part but for the given presentation the mids are done very nicely on the Aurora and is one of its strong suits. ts powerful low frequency response and transparent and mellow midrange performance, wide sound field, shocking sound quality. The generic shells are made of good-quality resin, and they fit my ears well…although, they are not the smallest around and could be thinner. And the mids is shinning and near, cohesive and smooth, when it turns to some IF instruments, Oh great resolution and right position.Shell designs that fit almost entirely in the concha of the ears that are closed designs like the Aurora do show a more intimate stage.
