Product Information

The overall signature of Aurora can be described as slightly V-Shaped, clean, clear, it has a flat tendency where it doesn't have a strong emphasis on lows and highs and only a moderate one.

Aluminum alloy is not only tough, impervious to minor nicks and scratches but keeps the weight of the earphones in check. From my highly technical footstep method I found the S1 had an open range of 15+ metre range without no obstructions.They are relatively upfront, mainly in the upper-mids/lower-highs range, while the lower mids are a bit toned down. If they added just a bit more bass it would have been a more L shaped signature and warm in tonality. They will be compared to other high quality IEMs including Dunu Falcon PRO (220 USD), Linsoul 7Hz Timeless (220 USD), and QoA Queen of Audio Adonis (190 USD). Seating the orchestra is better than the KS2 as instrument separation is improved compared to the KS2 and the driver speed definitely is noticeable here. The signature can be described as warm-fun-lively V-shape with a tad of plastic added (not too bad, though).

These isolates less than what your average IEM can, with background noise more audible than other passive isolated IEMs. interface,the detachable design provide great convenience for users who want to replace with another 2pin cable. Although, in terms of sounds between these and the BLONs, I will go with the BL03s more, since to me they sound much more natural to me, because to me the KS1s at times, sounds metallic to me.To use, you’ll need to power on the cable by pressing and holding the middle button, you’ll hear the usual robotic voice to confirm power on.

This is probably due to the thickness of the plastic used for the shells not being that thick to restrict outside noise from entering. Interestingly it takes EQ better than blons, blons become very boomy (on the other hand I don’t need to boost bass in bl03). The mids are slightly recessed, as you would expect with a V-shaped sound but they don’t sound hollow or distant.In addition, the capsules have a semi-custom shape, which provides such good results, in terms of ergonomics and isolation. 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. 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. This is in comparison to much higher end earphones that protrude outside the ears, Sony IER-Z1R for example. The driver is a 10mm Titanium-coated diaphragm single DD, and I was told it is a good unit with a high cost, I tell the good or bad only from the sound.
