Cable: a pretty standard 2 core cable, metal divider and 3.5mm connector. Has a working chin-slider. Durability should be fine since the buds themselves are pretty lightweight.

20210802_155246.jpg

Build: Entirely in metal but pretty lightweight despite that. It is a pretty tiny shell. Non-replaceable cable though.

Fit: Good but not as good as MX500 shells for me, they don’t feel as secure as those shells.

Comfort: one of the most comfortable bud shells out there I have tried.

Isolation: None, it is an earbud after all.

Setup: Schiit Asgard 3 (low-gain, volume around 8-9 o´clock), full foams, stock cable 3.5mm

Lows:
Typical bud bass and nothing impressive here. It is clean due to the speed and tightness (like the majority of buds out there) but not recommended for bass lovers.

Mid-bass: Metallica – fight fire with fire (01:11-01:52), very clean due to the fast and tight bass but lacking quantity and texture. The (02:55-03:01) section with the chopper is hearable and clean.

Hiroyuki Sawano – Pretenders (01:18-01:47), lacking quantity but otherwise very clean due to the tightness and speed.

Sub-bass: Djuro – Drop that bass (01:15-01:30), typical extension and rumble for a bud (that is, pretty much none-existent). Punch quantity is also lacking but it is tight/fast so it is clean.

Will Sparks – Sick like that (03:08-03:22), Lacking quantity and texture but is clean due to the speed and tightness.

Mids: Godly female vocal performance. Male vocals are also very good but tend to lack warmth.

Female-vocals: Hiroyuki Sawano – OldToday (01:25-01:52), Excellent vocal tonality and timbre, very clean and detailed. Instrument tonality is lacking some warmth but timbre is excellent and very clean and detailed.

Yuki Hayashi – MightU (01:58-02:55), Both vocals and instruments have excellent tonality and timbre, very clean and detailed as well.

Evanescence – Bring me to life (01:18-01:35), very good tonality despite no shout. Fatigue is due to the brighter tonality though.

Hiroyuki Sawano – Crescent (02:07-02:26), a bit shouty but very good imaging/separation.

Male-vocals: Hiroyuki Sawano – Pretenders (00:57-01:17), vocal and instrument tonality lack a little bit of warmth but excellent timbre as well as being highly detailed and clean.

Hiroyuki Sawano – Scapegoat (00:57-01:17), Lacks warmth with both vocals and instruments but very good timbre along with detail and clarity.

Treble: Linkin Park – Shadow of the Day (03:24-03:42), electric guitars aren’t sharp at all but very accurate tonality and timbre.

Deuce – America (03:03-03:16), fatiguing due to the bright tonality.

Hiroyuki Sawano – Lose (string version) (01:22-01:59), Cello tonality lacks some warmth and texture, but very good timbre, detail and clarity. Violin tonality, timbre, texture, detail, clarity and treble-extension are excellent.

Hiroyuki Sawano &Z (02:18-02:57), good tonality/timbre and very clean/detailed.

Soundstage: huge width as expected from buds, but not very deep.

Tonality: Extremely well-tuned neutral bud with excellent timbre and non-peaky treble.

Details: Highly detailed.

Instrument Separation: Imaging and separation are very impressive.

Songs that highlight the Earbud:
Good genres:
Vocal/acoustic music, OST, Classical

Bad genres: EDM, Trance, Hip-Hop, R&B



Comparisons:

Earbud: Yincrow X6, full foams, stock cable 3.5mm

Bass:
Djuro – Drop that bass (01:15-01:30), extends lower and rumbles a lot more on the X6. Punch quantity is also higher on the X6 along with more texture but it is cleaner due to the faster/tighter bass on the LBBS. Tonality is more accurate on the X6.

Hiroyuki Sawano – Pretenders (01:18-01:47), more mid-bass on the X6 along with more texture and it is more tonally correct on it. But cleaner on the LBBS due to the faster/tighter and lower bass quantity.

Metallica – fight fire with fire (01:11-01:52), A lot cleaner on the LBBS due to the lower bass quantity and faster/tighter bass. But more tonally correct on the X6.

Mids: Hiroyuki Sawano – OldToday (01:25-01:52), Instrument tonality is better on the X6 due to the warmth but better timbre on the LBBS. Vocal tonality, timbre, detail and clarity are leagues ahead on the LBBS (along with more quantity).

Bass:
Djuro – Drop that bass (01:15-01:30), similar extension but a bit more rumble on the LBB. Punch quantity is higher on the LBB but quality is a lot worse due to it being quite loose. Tonality is a bit better on the LBB but at the sacrifice of quality.

Metallica – fight fire with fire (01:11-01:52), very muddy on the LBB, a lot cleaner and detailed on the LBBS with better tonality.

Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument tonality is on the LBB due to the warmth, but it is quite bleeding from the mid-bass, better timbre on the LBBS. Vocal tonality, timbre, detail and clarity are leagues ahead on the LBBS.

Overall: The LBBS is superior to the LBB in every way except male vocals for a few tracks.



Earbud: K´s Bell-WE (bass version), full foams, stock cable 4.4mm

Bass:
Djuro – Drop that bass (01:15-01:30), extends and rumbles a lot more on the Bell-WE. Punch quantity is also a lot higher on the Bell-WE but it is quite muddy due to slower and looser bass. Texture is better on the LBBS. Tonality is more accurate on the Bell-WE but at the cost of muddiness.

Earbud: Moondrop Chaconne, full foams, stock cable 4.4mm

Bass:
Djuro – Drop that bass (01:15-01:30), similar extension but more rumble on the LBBS. Punch quantity and speed are similar, but tighter and more textured on the Chaconne. More tonally correct on the LBBS (higher bass quantity on the LBBS makes it warmer here).

Hiroyuki Sawano – Pretenders (01:18-01:47), a bit more quantity on the LBBS while texture, tightness and speed are better on the Chaconne. More tonally correct on the LBBS.

Metallica – fight fire with fire (01:11-01:52), cleaner due to the tighter and a bit lower quantity on the Chaconne. But more tonally correct on the LBBS.

Mids: Hiroyuki Sawano – OldToday (01:25-01:52), instrument and vocal tonality are very similar but slightly better timbre on the Chaconne. Detail and clarity are a step up on the Chaconne but pretty close.

Evanescence – Bring me to life (01:18-01:35), a bit more relaxing due to the bass giving it more warmth on the LBBS.

Hiroyuki Sawano – Scapegoat (00:57-01:17), instrument and vocal tonality are very similar (lacking warmth on both) but timbre and micro-details are a bit better on the Chaconne.

Treble: Linkin Park – Shadow of the Day (03:24-03:42), electric guitars are a bit sharp on the LBBS compared to the Chaconne but otherwise similar tonality.

Hiroyuki Sawano &Z (02:18-02:57), a bit better tonality on the LBBS but better timbre, detail and clarity.

Technicalities: Shiro Sagisu – Hundred years war (02:24-02:57), wider on the Chaconne but similar depth. Micro-details are better on the Chaconne, while the instrument separation and imaging are also better but not by a lot on the Chaconne. Timbre is slightly better on the Chaconne.

Overall: The Chaconne is the more technical and has slightly better timbre. But tonality wise, the LBBS is a bit more suited for my library. If you want the best you can get, the Chaconne IS better, but the value is massively better on the LBBS.



Conclusion: Well, unless you are a massive basshead that only likes bass, highly recommended.

@iemhater look at the cable. The LBBS has the cable I got here in my review above. While the non S version doesn't have the cloth part and instead just a regular cable.
