Product Information

You need to charge the Bluetooth cable with a power source not exceeding 5V DC, you can use any USB port on a laptop, TV, or a powerbank. These 2 sets are very close in technicalities, I think the KBEAR KS1 is just a bit better in the instrument separation and details departments.

Having tested them side by side, Falcon Pro is considerably warmer in the midrange and mid bass, it has more warmth, slightly more thickness and more substance, where Aurora has a colder, brighter sound that's more sparkly. I live in a two up/two down house and the S1 cable didn’t loose signal through walls and floor levels either.There is still some bass bleeding into mids, possible analytical head needing some cleaner bass for analytical listening? 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 that is included with Aurora is a bright blue in color, which subjectively is a bit odd / weird to see, but it is of a very high quality, flexible, very safe from microphonic noise, and not tangle prone.

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.

When I first put the KBEAR KS2 into my ears – listening to Canadian rock of the Guess Who – I could not get them out again, so appealing and irresistable was the sound. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others. They’re somehow “clean sounding”, no problems on that front, it’s just overall they sound, indeed “cheaper”, like lacking on all fronts. For non-nerds, this graph means that these earphones are the dogs nuts and are great for all music types.

So this is not a technical set for critical listening or analytical listening, but more for sitting back to chill and enjoy the music. This happens because there are so many good sounding earphones that all try to take the piece of the pie.I wasn’t a huge fan of the KS2 and honestly wasn’t expecting the KS1 to fare a lot better considering it was “a KS2 with the BA deleted”. First impression… Better than Moondrop SSR… That’s a good start… Definitely better than TRN M10… That’s another good start.
