Majestic sounding IEMs worth every penny
Good
best dac ever used the sound is incredibly good amazing the black colour is currently on top
Love it! My swimming sessions have become much more enjoyable and consistent. I also love listening to audiobooks and retro songs on these when not in water! Good product for a healthy lifestyle
KZ Duonic ka sound sach me bhut acha hai aur iski overall quality kamal ki hai. planar driver hone ki wajah se clarity next level milti hai. Bass tight hai aur instrument separation bhi bohot clear hai. Isme music suno bohot acha experience hota hai . Highly recommended if you love high-resolution audio!
It just works amazing with all of my audio products
These my first iems using it from last 2 months very nice very balanced sound
A beautiful pair of iems at this price range. Balanced sound, but engaging listening. Also good for monitoring.
Really good DAC and perfect for apple devices as it does not reduce the volume like few other DACs..and very good delivery experience from TAS..👍🏻
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"
