As such, with the rise of Chi-Fi in the last few years, he has never been happier with his audio hobby. It should be noted that I have absolutely no affiliation with KBEAR, I am not receiving any incentive for this review or to sweeten things out. To this set, an electronic crossover has been added, to take full advantage of the potential of its drivers.

Use spinfit CP145 tips and mod following this guide for smoother but still detailed treble and a more present mid range. In addition, the capsules have a semi-custom shape, which provides such good results, in terms of ergonomics and isolation. The dynamic driver has a wide scene, first impression gives a lot of details with a huge bass punch, as a V shaped tuning, still listening all good for pop misic and EDM ! Again, this user guide is poorly translated, but it’s an actual user guide this time with tips and user usage instructions. They clearly have a large shape inside the IEM with the function to create dispersion, or the driver is tuned quite uniquely, because they have a huge soundstage to my ears, with a ton of width, and a really holographic presentation, but at the cost of instrument separation which is fair rather than good.What makes the Wolfram interesting is that these cable has pure silver at its cores but has a copper shielding on them. In “real” life, Jürgen is a professional geologist operating his own petroleum-exploration consulting company Franconia Geoscience Ltd. I found them more comfortable for short listening sessions than the Spinfit cp145’s and they sound better too. The mid bass in particular has some recess to it, which can make Aurora slightly cold, but avoids the boominess and bloom of the lows.

Because of this some instruments get drowned over the bleed but also have the weird side effect of making the male vocals feel more present than their female counterparts. It is bottlenecked at the technicalities aspect and in the bass quality area, but I feel it would otherwise make a fine addition for those who are new to this hobby or those who want a laid back tuning that is different from the usual budget CHIFI fare. I do understand why too, as it is having wide soundstage, and instrument are able to space out greatly too, but really dont expect too good in instrument separation, as it is still a budget IEM. As they are, you get the nice contrast of a clean and tight sparkly treble with a moderate warm authoritative punch add to it a rangy dense mids presentation all in a well imaged intimate sound presentation. Prime Audio Reviews was created so I could share my passion for audio gear with people around the world.The bass aspect of the Aurora benefits from burn in which I highly recommend folks do with their Auroras to get the best sound out of them. These isolates less than what your average IEM can, with background noise more audible than other passive isolated IEMs. I also found if you press and hold it’ll summon the Google assistant lady who tells me I have no plans (obviously ? Lower treble drops back again after the upper-mid rise but comes back up to the upper-mid peak at around 5kHz which adds enough energy to help with snare rattle and hi-hat hits. The midrange has a sweet tonality and works perfectly for female voices, guitars, and even more aggressive instruments such as trumpets sound enjoyable and non-fatiguing, non-harsh.
