Great resolution and detail with clear vocals.
Perfect for use as reference earphones. They are more true sounding and easy to drive with mobile devices.

Not recommended for bass lovers and bass heavy genre like EDM, electro.

Perfect for acoustic, pop, classical music and gaming.

What can improve :
Carry case is too small.
Wire is a bit short. 1 more feet would be nice.

It's my first big step forward into the world of IEM, I'm really happy with my purchase it is just as I expected it to be but somewhere I have this problem as I work for 9 hours and have stay active on zoom meetings if you'll wear these for longer time due to pressure in years it can be uncomfortable so good for 1-2 hour usage it can be me only as my years are quite out due to my medical history so people with moderate use won't have to worry much.

Though it is fairly easy to drive with any dongle dac like link 2 bal or M15 but it really transforms itself into different beast altogether when connected to something like hip dac or xduoo 5+

Sound signature is neutral with less of sub bass more of mid bass boost. Bass is not lacking in any way (as mentioned in few online reviews) but little bit sub bass extension could have given this iem little extra flavour. Good speed and very good details like a capable DD. I did not feel any ba timbre.

Treble is extremely smooth, musical, rounded and easy for long listening. No harshness no sibilance is noticed.

Vocals sound crystal clear, forward and full bodied with 3D effect, feels like sound coming from all around your head. Midrange is where O lite shines most.
Imaging is amazingly good in these iem. Very easy to pin point each instruments with precise accuracy. Instrument separation too very good for the price, no complaints whatsoever.
Detail retrieval is another area where the tuners of this iem have done commendable job. Full marks to them.
Soundstage is where this iem lacks a bit if I nitpick. Could have better space between you and the singer/instruments. Lacks little air. SS is kinda narrow but again since I prefer narrow stage (not too narrow or congested) to enjoy my vocals, here too I don't have any complaints.
But the real disappointment comes from its lackluster accessories. With the price point of $250 they could have provided a modular cable or an option of 4.4mm at least. Ear tips are trash. Carry case is too small to use.

Last but worth mentioning. Don't listen to this iem empty stomach otherwise you will eat up whole iem since it gives a feel of green candy in your hand. Shells are extremely extremely gorgeous to look at.

Cons
Big Shell, single ended cable, poor accessories, lacks sub bass extension, treble may feel too smooth sometimes to someone.
Thanks

Great iem for all music genres. Male and female vocals sound excellent, but it shines with orchestral music, anime, and movie soundtracks. The gaming experience is fantastic due to the fantastic imaging, layering, and depth. I can pinpoint enemies in Apex Legends, CSGO, and Valorant. It can take EQ very well in all frequency ranges except sub bass. Due to being an all-BA, the sub bass lacks the powerful rumble. Overall, it is a highly detailed and high-resolution IEM that is suitable for competitive gaming and nearly all music genres (The absence of rumbly sub bass makes it an okay choice for rap and EDM music).

They lean on the warm side, which makes them very easy to listen to for extended periods of time. Bass is also great for a BA set.

Was not sure how the BA bass will sound as I had never experienced all BA sound signature. Pritam was of great help here as he answered all my queries about the BA drivers. I was pleasantly surprised by the bass which is just perfect and the details are also clear. Soundstages is not that wide but the instrument separation is superb.
Thanks Pritam for a great recommendation as it was him who asked me to wait for the release of this iem.
