In this review, I will only talk about the sound and my experience with the IEM.
Long story short, the Dusk is an IEM that requires considerable time for people to understand what it can do and how to use it correctly (At least for me).
On 9/2024, I got my Dusk and listened to it on the DSP cable for the first time. My impression that time can be concluded into one word: "BASS". As a former user of B2, the bass of the Dusk at that time was kinda too much for me. However, the more I listened to it the more I came to get addicted to how rumbling the Dusk sounds while maintaining the clarity of the midrange, regarding the superior technicalities compared to the B2. You can say that the DSP tuning is to the liking of the majority of people, who listen mostly to rap, pop, and EDM. On the other hand, although the mid provided great clarity and coherency, the vocals could never shine on this kind of tuning as it became the very opposite of forward. Most of the time, I found the vocals sank in the track where different instruments and things were going on.
Turning to the 3.5mm cable, as I plugged directly into my computer, I found myself in great disappointment. It was just like the Dusk lost its strong point: the bass was anemic and amateur while the treble was way too bright and sharp for my ears. Fortunately, the soundstage and mid did not change. The vocal seems a bit forward compared to the DSP tuning. But to be honest, the dusk with 3.5mm cable sounded so bad that I even found some KZs sounded better. At that time, I felt like my money was wasted on the Dusk in analog mode and promised to only use it with the DSP cable.
That way, my taste in music gradually turned from vocal eccentric tracks to Rap. I craved nothing but the high-quality bass that the Dusk provided. However, as time went on, I realized that the DSP cable was too much of an inconvenience. The first reason is the fact that I could not connect it to some devices, in particular, my iPhone. You know, sometimes you just want to go outside with a pair of IEM listening to music but with my iPhone and the Dusk, I could not do it, which is extremely frustrating. The second reason is the sensitivity of the Dusk. The more I used it, the more I felt like there was a hissing noise while playing classical tracks. I do not know if this is due to the DSP cable or the Dusk itself but that noise is right there. That was also part of the reason why I mostly listened to Rap using Dusk as the bass could kind of make me forget about the hissing noise.
This is when I started to be depressed about the Dusk. I even had the intention to sell it as I thought this IEM was not worth it. Listening to the DSP tuning of the Dusk did me dirty as all I cared about was bass and how it hit in rap songs. I no longer cared about other things such as mid, treble, or soundstage. "If an IEM hits bass the hardest, it is the greatest" - kind of mindset. Fortunately, it came to an end.
As I researched ways to make my Dusk worth the money, I found out that the Dusk in analog mode takes a dedicated amount of power and source. So I chose a portable one that can provide those: FiiO Q3.
Now we are talking, the Dusk in analog mode with a great source is the IEM that I consider worth the money (or maybe this is the doing of Fiio Q3). It is nothing like the DSP mode, the Dusk in analog mode can be seen as a vocal-eccentric IEM. I am not great at describing things so in summary, it sounds like a B2 with greater technicalities, timbre with elevated high mid. The bass is not much but tighter and has enough thumps. High mid is like the very main point of the Dusk: Sounds extremely smooth but no sharpness is present. Vocals now feel natural and forward. And the most important things are imaging and soundstage gets taken to another level, which makes the experience of listening to the Dusk feel like the singer is right in front of you.
The hissing noise that I mentioned is gone using a 4.2mm balanced cable (it is still there using a 3.5mm cable so I guess that noise is related to the sensitivity of the Dusk).
Overall, it was a long journey to finally properly use the Dusk. Right now, I can say that the Dusk is worth my money (or maybe this is the doing of FiiO Q3, I never know). It goes to my taste as the vocals and instruments really shine and feel natural on this IEM. I also really enjoyed the Dusk in DSP mode but I wish I could have this experience without using DSP. Maybe I will get a mk2 in the future.
Thank you for reading this post till the end and I wish you guys a happy new year.
