They’re somehow “clean sounding”, no problems on that front, it’s just overall they sound, indeed “cheaper”, like lacking on all fronts.

The mid range can come off as a little distant and thus not as natural compared to the Blon BL03, but detail is good.

The Aurora has been burned in for a weeks' time and is now ready for evaluation using my sources the IBasso DX300Max, Fiio M15, Shanling M6 pro, M5s, M3s, Ibasso DX160, Fiio K3 2021, and IFI black label for amping. The cable is listed as four core 4N copper and is encased in black plastic matching the jack instead of the brown casing used on the KS2.

The sub-bass is improved over the KS2 stable-mate with a bit faster attack and decay and improved detail as a result. Nintendo Gameboy Color - KS1 picks up slight noise due to sensitivity less of an issue with the less sensitive Blon BL-03. Their products not only excel in delivering excellent sound performance, they also have superb ergonomics and build. The cable is also of an excellent quality, and Aurora generally feels like a high-end IEM as far as the construction goes.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. With the Storm having safe curves and no extreme protrusions, I find them comfortable for long periods of time before introducing ear fatigue. You might be (or not) interested to know that the cable is made from high-quality OFC (Oxygen Free Copper) copper cable. As such, with the rise of Chi-Fi in the last few years, he has never been happier with his audio hobby.

Inside the box is the usual foam insert with the earphones on display and another smaller box containing the accessories.Luckily that Aurora works well with such portable DAPs and will be much better when meeting good source.

The sides of the cover are black and show the logo, in silver letters, and the model chosen, in this case «Green no Mic». What I hear is a fast and well-defined attack with a medium decay speed that gives the sound a natural weight. In fact, the KBEAR KS1 is warm and analoguish and the tuning is pretty non offensive and non fatiguing. The Aurora is not perfect by any stretch but it does have a solid sound foundation for all things music. I was in a bit of a pinch to post my review here before launch, so I had to take the Aurora and my camera to my work.I don’t care much for fancy packaging as I think that money is better spent on the IEM’s themselves, so this is fine by me. Vocals are breathy and attenuated with a splash of pressurized air added, but they are quite there and very 3-dimensional. According to KBEAR, the cabinet cavity of the KBEAR KS2 is made of an imported high-density PC material which can suppress the diffuse reflection of sound waves inside the cavity. That been said, if you're into music that has more emphasis on traditional instruments (like folk derivatives), then V90 is probably a more suitable choice after all.
