Intro/disclaimer :
- This unit was sent to me for review, I didn't pay for anything
- As always don't rely on a single source of info for purchasing decisions
First Impressions :
- Unboxing : The packaging is much better than the previous Shimin Li, mostly because of the inclusion of a pouch : while not as secure as a case, it's easily usable and carryable. The tip selection is generous as always, and the presentation is better than simply throwing in plastic bags filled with tips. As of now I prefer it with the S&S tips, the Final Type E and the stock white tips that are on the nozzle by default (in that order).
- The shell size is nice, small enough to fit most people and the nozzle grips firmly on the eartips. The only drawback would be its weight, it will get tiresome after some time (i can wear them fine for about 2 hours, any longer and the weight becomes a bother)
Sound :
- Stock tuning is good, although overemphasized in the early high mids (2-4k). from 20 Hz to 1kHz it's really nice, linear and coherent but then you get to the zenith at 2kHz and it's at least 3-4dB too much in this region. There's also a minor peak at 8kHz but that is the only disturbance in an otherwise very well done treble region.
- It's surprising to rediscover what the Shimin Li is capable of when its first launch was flawed by reflection issues : the original version had reverberations inside the shell and you could hear the echo which was highly disturbing. Here, you get a very nice set with surprisingly sharp transient response for a dynamic driver, and the acoustic chamber is clearly doing something because this set sounds bigger than anything in its direct competition.
- The bass on the Red Li is damn clean for a 50$ set, in my opinion cleaner than the DLC driver based offerings we got used to in this market recently. Although not as sub-bass focused as those are/were, the tactile sensation is present and this set extends deep and in a clean manner. Its midbass is polite, but lacks definition to fully represent acoustic instruments like cello faithfully.
- The mids are really clean and voices are very well reproduced. Guitars are not as pleasant unfortunately because of the push in the high mids : electric guitars will appear much too shrill and buzzy compared to the original track. No warmth nor clinical approach in the mids, it is neutral in its conception however doesn’t sound the most natural, which I think is due to a lack of details that would render the region more realistic otherwise.
- It takes some time to adjust to the replay of the treble on this set, but this is because it's one of the rare sets in this segment of the market that actually plays back treble to its end, meaning there's no sharp drop after 15kHz like we commonly see in IEMs under 300$. Having information in the air region is nice but it's not the strong suit of the Red Li : information is present in a faint amount, and this set's impression of height is lessened because of that.
Technicalities :
- The Red Li sounds much wider than tall, and its three-dimensionality impression is warped because of that. You don't get a holographic image like you'd want to, but more so a peanut shaped one : two spheres and a central portion that is narrower. Even so, it's much more able than its competition if you stay within the constraints of this space : replay of small rooms and studio setups is excellent for the price point.
- The detail retrieval is on par with most 80-100$ offerings, the likes of the Aria, Kai and Kima. You trade the sub-bass rumble for more coherent mid-to-bass tuning, and better extension overall.
- Transients are much tighter on the Red Li compared to its predecessor. While not BA levels of attack, it's better than the competition and leads to a more realistic feeling overall when pitted against the other single DD IEMS (the aforementioned Aria comes to mind)
EQ :
Preamp: -4.99 dB
PK 10000 Hz, 2 dB, Q 1
PK 8000 Hz, -2.5 dB, Q 6
PK 6000 Hz, 6 dB, Q 3
PK 4400 Hz, -5.3 dB, Q 2
PK 2200 Hz, -4.4 dB, Q 2
PK 720 Hz, 1.8 dB, Q 0.5
PK 21 Hz, 2.42 dB, Q 0.6
Conclusion :
In my opinion this set's validity to be bought comes from its EQed state, with the stock tuning I don't think it's enjoyable enough to justify the 50$. With EQ however it's another story altogether, and it deserves its place alongside the Hexa, Galileo, S12 in the ranks of the "better than the Aria" category which is unprecedented for the money.
