Binary EP321 MEMS Tribrid IEM

Various reviews on the net created a lot of desire and interest to possess this iem.
Hitherto iv been buying audio gear from some other website who did not have this iem in stock.
Thought of buying from Audiostore.
I spoke to Mr Pritam and finalised the deal. Personal interactions do add up to the textual.content you gather from the net. Delivery was exactly as promised.
My first impression of the iem is Spectacular sound reproduction!!!
Songs thatIheardliterallyfelt like being played in front of me.
Bass sufficiently good enough for every listener except bassheads. Of course bassheads would lose considerable amount of ther sonic capabilities.
Soundstage wide and imaging is excellent. Inspite of good bass every instrument is distinctly clear and precise.
Only request for Audiostore is to include other leading brands like Fatfreq, Fiio, Ibasso etc.

My honest review these are best and luxury looking IEMS and I love them and they fit in my ear perfectly for me and I love them

This IEM sound really good for everyday listening. The Bass has a nice punch,Vocals come through clear and the overall sound feels balanced and enjoyable.They’re comfortable to wear for long periods and block out a decent amount of outside noise.Easy to carry around as it’s comes with a pouch and Great for Music,Videos.Definitely worth it for the price, and specifically thanks for audiostore team.❤️❤️.

The bass in these stays present and hits quickly. An easy term to describe the feel is cinematic bass. And it get loud very fast recommend use Low gain with high volume or High gain with Low volume. Prefer your your choice.

After 10 days of use, I feel I made a great upgrade from the 7Hz Elua Ultra. The main differences are that the Elua has laid-back vocals and sub-bass rumbling, while the STA Hi-End surpasses those limitations with good imaging, zero distortion at high volumes, and cinematic punch in the sub-bass.

Here is the detail review with help of claude to differentiate the same batch of IEM just at "ONE POINT"

looks good , Sound is balanced, you can listen music,watch movies and also good for gaming.Bass is good not that much punchy but does not muddy details . No distortion at Max volume .

At first use I have loved the sound and the fit of the iem so far the best budget iem I have ever used go for it guys value for money product.

The DAC has no hissing sound and the other shell is build of metal. great wire quality no heating issues as well. also the red light is menacing as hell. also case is included which is fine/cheap quality. also type a to c converter is also given in box.

This is a very comfortable IEM, I can wear them for hours without experiencing discomfort or ear fatigue. The shell are relatively small, very light and fits perfectly in my small ear. The eartips are also good and doesn't cause irritation in ear canal.

It is my first iem that i have purchased and it turned out to be the best decision ! I researched a lot before buying it as i am a bass lover. Finally bought KZ Duonic with switches c type. Every note is so clean and for every type of song it adjusts the sound. Delivery was before time and even the packaging was great! Thank you The Audio Store ❤️

After trying multiple ear tips, finally I’ve settled with Divinus Velvet ear tips along with Spinfit-W1. This is perfectly sealed for me and gives that great sounding with any of the IEMs I own. Recommended. Thanks audiostore

Its perfect no doubts there but the silver plated itself is high quality but wire built and the eartips are of low quality mic is clear and perfect.🔥👍

One of best Dac in upper mid range category, it has most powerful Sgm8262 amp along with Cs43131 successor dac. The Aura seamlessly connects with my iPhone 15 and my window Laptop. Sound quality omg what a mind boggling Sound I am getting through this with MoondropNice earphone. That's exceptional. Somehow it has connections issues with My oneplus nord 4 due to oxygenOS 15. May be it will sort out after oxygen OS updates.
ThanksAudiocular team .

I loved it , surprised totally. What a sound separation.
I was a bit sceptical about ordering it from The Audio Store as I order from Headphone Zone.

But great shopping experience with The Audio Store.

This is first time experienced IEM in ever I love this❤

Perfect fit with perfectly balanced soundscape for my personal liking and genres! Thanks a lot for audiostore!
