Price: 7,78 usd currently (paid 6,3 usd during the sale)
Specifications:
Diaphragm: PET
Coil: Daikoku
Magnet: Rubidium Iron Boron / (RbFeB)
Sensitivity:106db
Impedance: 32Ω
Unit diameter:15.4mm
Frequency Response Range:20-20KHZ

Clip
Carry bag
1 pair of full foams
1 pair of donut foams
Cable: brown 5N Litz OFC 4-core cable (reminds me of the old KZ cables), that is actually pretty decent considering what the cable on other buds usually are like.

Build: Nothing special with the build, just a typical MX500 shell.
Fit: MX500 shells fits me so it’s good for me.
Comfort: Good like every other MX500 bud for me.
Isolation: None, it is a bud after all.
Setup: Schiit Asgard 3 (low-gain, volume around 9 o´clock), full foams, stock cable 3.5mm
Lows: Better bass than average for a bud. A bit more sub-bass focused than mid-bass and while it isn’t the most textured nor deepest extending bud (even at this price range) it is still pretty good. Overall tonality gets warmer and a bit thicker note weight thanks to the elevated bass.
Mid-bass: Metallica – fight fire with fire (01:11-01:52), quantity and speed are pretty good but could be tighter because it is a little bit bloated and texture could be better. The (02:55-03:01) section with the chopper is hearable but not that clean.
Hiroyuki Sawano – Pretenders (01:18-01:47), fun due to the quantity and texture but still pretty clean due to the speed and tightness.
Sub-bass: Djuro – Drop that bass (01:15-01:30), extension is good for a bud and there is some rumble. Punch quantity is decent but needs more quantity. Speed is fine but could be tighter and more textured.
Will Sparks – Sick like that (03:08-03:22), good quantity, speed and tightness but could have more texture.
Mids: Excellent male vocals due to the warmer tonality. Female vocals are very good as well, but not as good as the male vocals since they tend to lack some brightness.
Female-vocals: Hiroyuki Sawano – OldToday (01:25-01:52), instrument tonality and timbre are excellent. Vocal tonality and timbre are great. Macro detail is good but better micro-details than usual. Clarity is bottlenecked by the warmth.
Yuki Hayashi – MightU (01:58-02:55), both instruments and vocal tonality needs to be brighter but natural due to the timbre.
Evanescence – Bring me to life (01:18-01:35), relaxing and non-fatiguing.
Hiroyuki Sawano – Crescent (02:07-02:26), a bit shouty and chaotic.
Male-vocals: Hiroyuki Sawano – Pretenders (00:57-01:17), great vocal tonality and timbre.
Hiroyuki Sawano – Scapegoat (00:57-01:17), very good vocal tonality (could be a bit warmer though) and timbre.
Treble: Linkin Park – Shadow of the Day (03:24-03:42), electric guitars are a bit sharp.
Deuce – America (03:03-03:16), not shouty but pretty chaotic due to the separation.
Hiroyuki Sawano – Lose (string version) (01:22-01:59), Cello tonality, timbre and texture are very good with good detail and clarity. Violin timbre is good but tonality (needs to be brighter), treble-extension, detail and clarity could be better.
Hiroyuki Sawano &Z (02:18-02:57), very good tonality and timbre. Pretty clean and detailed as well.
Soundstage: Huge as expected from a bud but also very deep and is holographic.
Tonality: bass-boosted neutral, not as much bass boost as others but definitely more than usual. Is on the warmer side and has thicker note weight than usual.
Details: Very good (especially micro-details) considering the price.
Instrument Separation: separation and imaging are good but definitely bottlenecked by the warmer tonality.

Earbud: Faaeal Iris Ancestor, full foams, stock cable 3.5mm
Bass: Djuro – Drop that bass (01:15-01:30), extends lower on the 2.0 but rumbles a bit more on the Ancestor. Punch quantity is higher on the Ancestor but similar texture while it is faster and tighter on the 2.0. A bit more tonally correct on the Ancestor.
Hiroyuki Sawano – Pretenders (01:18-01:47), cleaner due to the tighter and a bit faster bass on the 2.0. While the Ancestor has more quantity but similar texture. More tonally correct on the 2.0.
Metallica – fight fire with fire (01:11-01:52), bloated on the Ancestor in comparison to the cleaner 2.0 due to the tighter bass (speed is similar) and also lower bass quantity on the 2.0.
Mids: Hiroyuki Sawano – OldToday (01:25-01:52), vocal tonality and timbre are very similar but cleaner on the 2.0. The Ancestor has a bit better instrument tonality (similar timbre though) but does bleed a bit into the mids which causes the 2.0 to be cleaner overall.

Overall: The LBBS is outclassing the 2.0 but the 2.0 is the better bud if you want a more relaxing and fun (bassier and warmer) bud.
Conclusion: The Iris 2.0 is a very well-tuned bass-boosted neutral that’s on the warmer side, making it a relaxed bud. Essentially like an Yincrow X6 with less bass and warmer tonality. Thanks for reading.
