Let customers speak for us
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❤
I’ve been spending some serious time with the Hisenior Mega5-EST paired with the FiiO KA17, and honestly, it’s a killer combo. These IEMs have that nice, punchy bass that makes movies feel immersive, but they quickly settle into a clean, neutral side that I really appreciate. The standout moment for me was listening to Tool’s 'Invincible'—the way this setup handles the complex layers and those dual EST drivers capture the 'air' in the track is just amazing. Everything stays perfectly separated, even when the song gets heavy. Huge thanks to Pritaam for the great interaction and for helping me with the selection ; it’s exactly the kind of balanced, high-performance sound I was looking for.
Good product and excellent packing, pouch was also good quality one
The vocals are excellent, it competes with any IEM priced between 1000-1700. I bought it for less than 1000, so definitely go for it for less than 1000. One more thing, if you're a bass lover, you might find it a bit balanced, meaning it's not as bassy, though vocals are more important to me, so that's why I bought it.
This is awesome. You can hear all frequencies individually with standard level. No comparison with earbuds or wireless headphone
Really liked the design and sound . Am new to IEM’s so really not sure what to expect but sound quality was really good and better then my oneplus buds 4. This review is for newbie like me
Clean sound, loud bass. Pretty balanced overall.It still is a bang for the buck.
