AROMA Audio Jewel
"AROMA-Jewel" is the crystallization of AROMA Audio's pursuit of the ultimate gorgeous sound. In addition, its voice matches the word "gorgeous". As a consequence, we name it "AROMA-Jewel", which is as gorgeous as a gem.
It is characterized by magnificence and high penetration power. After a long period of research and development, it finally decided the configuration of 6 electrostatic drivers, 6 balanced Armature drivers and one 9.2mm dynamic driver. "AROMA-Jewel" has magnificent, penetrating sound and broad sound field. In addition, the characteristics of the three units are all brought into play to the extreme and combined.
The electrostatic and moving coil units among the three units of "AROMA-Jewel" are independently developed by AROMA Audio because of AROMA Audio's endless pursuit of sound, bringing the best sound to users.
The high-frequency and even ultra-high-frequency performance of multiple electrostatic units seems to be unlimited. Besides, the lines feel clear and bright. The 9.2mm moving coil unit brings excellent diving depth, dynamics and air sense at low frequency to ensure the accuracy and integrity of the overall sound. When the moving iron unit is used as a connecting role to connect the sound of the electrostatic unit and the moving coil unit, the performance of the moving iron unit in the intermediate frequency is also very clear and bright, coherent and natural, with dense sound density and a clear sense of hierarchy.

For those who don't want intermediate steps and relative loss of money, I recommend pointing directly to these (if you are looking for the best analytical IEMs) or on the Trailli (if you are looking for the best IEMs with analog sound). I preferred these to enjoy all the dap/dacs I have and discover the differences in their sonic signature. Good music to all.
Everything else is going to be a side-grade after the Jewel. My previous favorite iem was the UM Indigo but the Jewel is easily a tier above. I would say the Jewel is a mildly mid-centric sound signature with excellent sub-bass. The mids are clear and smooth, with precise spacing and detail across the entire range of frequencies so every sound has room to come through without compromise. The vocals for both male and female voices are very honest and revealing of the actual recording without coloration. And when I focus on listening to the bass it's some of the best bass I've heard, yet it doesn't dominate and it exists in its own space. When the song has strong bass notes the Jewel's dynamic driver can do any heavy lifting required with grace and high-resolution. Treble is stellar too, never too bright or dialed up, always accurate. I think the Jewel strikes a brilliant technical balance between power and control. It quite beautifully handles complex classical music, electronic music, voice and guitar, even 90s rap and every genre I've tried with it, always revealing rather than accentuating the recording.
Still breaking in with Venom cable. despite the lack of breakin hours, the Jewel sings better than any of my top tier IEMs. It needs 150 hours to sound its best , but only has around 70 at this point.
Suitable for almost all types of music，The midrange and bass is absolutely top-notch。Definitely my top 3
At first, I was amazed by the beautifully integrated treble range played by the 6 ESTs.
I was intoxicated by the vocals, which were easy to hear every detail in the solid mid-range.
I was incontinent at the end with the heavy bass melody that came up from the depths.
So far I can't find any flaw in the sound.
