Tanya already has established herself in the sub-$30 mark. Tanya has excellent tuning and pleasing tonality. It is slightly warm and dark; but vastly enjoyable. Technically, Tanya is not quite adept. The sound is cohesive and all staging is intimate. These rival Quarks and Re400. Quarks have a bit of shout and edge to the vocals while Tanya is more full-bodied and lush. When it comes to Jazz and Blues; Quarks edge out Tanya because of their more elevated Treble. Quarks represent a more airy and elegant presentation of the high-hats and cymbals, but the lingering and brooding double-bass strums and dense Sinatra's vocals come to life through Tanya's lower-end prowess. When it comes to Between the Buried and Me's carnage in Colors II, I will be in a sheer dilemma - but I will pick Tanya. Some albums are more enjoyable in Tanya while others are in Quarks. Tanya is built a lot better though. So comfort-wise, both are in the same page - but the edge might be with Tanya.

I did expect a fair bit more in terms of technicalities, but I am quite happy with Tanya! They beat my Kinera BD005 Pro and KZ ZSN Pro - easily. But, KZ has more gravity to it as a brand than Tanchjim - although Tanchjim produces far better IEMs (Oxygen, Hana, Darling).

First, I want to tell at 2k price segment it is better I've ever heard, I listened byerdynamic byron, soundmagic e10c, e50c, pioneer CH3t,1more dual driver.
For build quality it gives best, with sturdy cable, very lightweight, good comfort. It comes with good packaging, with lots of eartips and one pouch.
And the sound part here, I must say at the low end part of any songs is fantastic, deep bass is very good and fast also. Lows sound reproduction is enough. And vocals are also sweet of male or female, though little recessed I think. One negative part I found, siblings little more compare to all earphones I heard before it's little harsh when you listening words with 's', 'sh' etc. Tonality is good. And treble is ok, good separation not extended but little engaged though it is musical. For this semi open design its soundstage is great means great, at many songs few instruments coming far away from my ear.
This is the out of the box performance, I'll put for burn in for about 50hrs and I'll check how much it is matured or not as Preetam from this "the audio store" advised me. He helped me to find this, thanks him.

Yes, this thing requires a considerable amount of power for the technicalities to be revealed properly. But, don't avoid it just because you don't have anything powerful to drive it because the tonality is absolutely amazing. Despite being a slight V shaped, the vocals, both male and female are rendered so beautifully. So if you listen to anything that is vocals dominant, get it because the tonality is pretty much the same at any power levels.

Now related to non-sound parts, this is a full packaged item, It has 6 pair of tips which actually fits, so no need for tip rolling or look after new eartips if this is your first good earphone. The build quality is pretty awesome and the cable looks and feels sturdy. It is non removable, which is a con but you don't (can't) have to swap cables. It is also very comfortable to wear and will fit probably everyone.

So I would recommend this over BLON BL03 on a budget and invest the remaining on a decentish DAC because BLON would most definitely need atleast an eartip swap or in worse case a cable swap.
