I was using the BLON BL-03 previously and was looking for something different but in a different format so picket this one up after discussing with the lovely Audio Store team.
Quite warm and smooth sound signature with the perfect amount of bass and treble with lovely mids.
I would suggest(the Audio Store team also suggested me the same) you to invest in a portable DAC/AMP for an even better sound stage and performance.

Thanks team Audio Store

Super fit, Good bass, sound stage, clarity and long hours of hearing, needs power to unleash the potential. Good choice.

Well not going to discuss the technicalities...will just tell you one thing i have compared this with Bl o3 , sound magic e10c , ve monk plus , rha ma 390 , jays one plus , hifiman re 400 , and i can tell you yes it needs a dac 9r dongle...but it's a pleasing iem...and under 2k you won't get it...and yes i like this over bl 03 because it's more pleasing and a lot more comfortable.

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).
