I've been using the K'searphone LBBS for about a week, they have a lot of tonality problems that can be improved with EQ. I don't hear these buds as very neutral at all, they are rather W shaped. (mid bass/fundamental frequencies bloat, harsh shouty mids, peaky treble). I know the sound changes a lot depending on how you wear them, and I am wearing them so they sound their best.
After EQ these earbuds sound good, the imaging was already interesting which made it nice for acoustic music.
Here is the EQ curve for the LBBS, this makes it sound like a "true neutral monitor" to my ears. Note that the area highlighted in crimson is a no guarantee zone, you will hear the high frequencies very differently due to ear canal resonances. For me, I get a resonance peak around 8k on the LBBS (the 6k stabbing peak is still real), for you it may be different. I also hear the LBBS as having essentially ripped out air frequencies, so I put a high shelf filter to compensate for that.
edit: i am using full foams on the earbuds btw
@shoui catemoji @Yyooo - Good day gents, have you confirmed that you both indeed own the Ks Bell-LBBs and not the Ks Bell-LBS? An older and much inferior model, the LBS call sign is a rather strong harsh mid-forward sound signature. While the Ks Bell-LBBs is far less forward and much more ear friendly.Totally agree, after a month of using, I don't think LBBS is neutral like some people said, mid is so harsh.
2018 - K's Temperament 小铃 Bell-LBS 30Ω (aka "Original Little Bell-Silver")
2020 - K's Temperament 小黑铃 Bell-LBBs 30Ω (aka "New Little Black Bell S")
The reason why I ask is that over the past year or so a good number of people have either mistakenly bought the LBS thinking it was the LBBs or they literally were tricked (baited and switched) with an older LBS which was repackaged and even relabeled as the LBBs / LBBS.
If you send a pic of both your earbuds and the serial number sticker on the box we would be more than happy to inform you which model you have. Cheers.
With that said some people do hear a "W-Shaped" type sound signature from the LBBs while others hear only a slight "Inverted U-Shaped" type tuning (I sit in this camp)...
Primary = Mid-Centric - Neutral
Secondary (Strong) = Warm (not muddy, nor muffled)
Secondary (Weak) = Sharp & Detailed
Tertiary (Complementing) = Hard-Harsh (enhanced female vocals; sometimes aggressive though)
Tertiary (Alternative Complementing) = Forward Mids - W-Shaped (while others may only hear a slight "Inverted U-Shaped" instead)
Tertiary (Opposing) = Hard-Harsh (not overly bright-sibilant it can get "too exciting" for those sensitive to highs)
Tertiary (Opposing) = Thin & Tinny (prone to aggressiveness)
The primary sound signature (red dot and red-shaded oval) of the Ks Bell-LBBs is "mid-centric - neutral" that may offer an ever so slight "inverted u-shaped" type tuning with a very strong secondary sound signature (larger blue shaded balloon) that reaches out to "warm" but is far from being muddy, smeared, or muffled. A non-overpowering weak secondary sound signature (smaller blue shaded balloon) reaches out to "detailed" for greater resolution and more realistic, natural-sounding timbre. Prominent complementing tertiary sound characteristics (green shaded arrows) are exhibited in the upper mids and very lower treble that may/can come across as being rather "hard-harsh" but in-turn also provides enhanced female vocals and reproduction of bright-leaning instruments. Due to mildly recessed mid and upper highs a sneaky and quite "aggressive" ("thin & tinny") opposing tertiary sound characteristic (green shaded arrow) may rear it's ugly head occasionally with certain recordings and music genres. Some individuals may hear an alternative complementing tertiary sound characteristics (purple shaded arrow) which reaches down to forward mids ("w-shaped" type sound) while others may hear only a very slight "inverted u-shaped" type tuning (I sit in this camp).
Please Note - It is crucial that you do not interpret this chart two-dimensionally but rather three-dimensionally using all axes offered. Optimally, this would be best presented as a sphere but in turn that would make it difficult to clearly see and read all the labels and sections. Thus, we are limited to two-dimensions for the sake of presentation and clarity. Please note that I tried my best to stick to the "classic" (more basic) sound signature & tuning characteristic definitions as used by recording professionals & audio engineers.
Some transducers may exhibit multiple and opposing tonal attributes all at the same time. I tend to plot earphones by their strongest attribute(s) first and then do my best to fine tune their position based on their other (minor) attributes.
