TRUSTED BY OVER 60K+ MUSIC ENTHUSIASTS
Let customers speak for us
Good for:
>Vocal dominated tracks (general bollywood songs)
>Indian classical in vocal. string and wind instruments, acoustic guitars.
> Western classical focused on Piano, violin and cellos (e.g. Ludovico Einaudi, Lang Lang)
Need a little twigs in eq:
> Female vocal may need 2-3 db boost in at around 2k region.
> Old tracks designed for tapes and cassettes generally has treble boosted in default. Hence a 1-2 db pull down in 8k &16k band makes it more enjoyable (e.g track - Nahi samne from movie Taal)
Not good for:
> Heavy rock and metals that demands more throbbing base.
> Heavy electric guitars mainly power chords & overdrive base guitars sounds muddy.
> Lacks wide sound stage required for large and dynamic orchestral pieces. Like cornfield chase by Hans zimmer, Nostalgia by Yanni
> Hip-hop and Electronic tracks lacks the attacks and punchiness
VERDICT:
> Deep and tight base, buttery soft mids and well defined and perfectly rolled out treble that doesn't heart your ears after a while.
>Go for it if you are a bollywood song lover. You can't get anything better, at least at this price brakets.
> Shines well with Sigma-delta dacs but feels bit too warm for r2r Dacs. Although some people can prefer that. But do not use it with a very powerful amp. Personally I felt opamp like MAX97220 is more than enough.
> Base is deep and tight. So do not buy this if you want thumpy base.
> Not a flat responding iem. So do not consider it if you want an analytical piece. > Choose it if you are looking for long listening sessions with deep imotional attachment rather than analytical detailing.
This pair is one of the most musical and cohesive IEMs I’ve heard in its price range. Its warm-neutral tuning delivers rich note weight, natural timbre, and excellent tonal balance without sacrificing detail. The bass is textured and controlled, the mids are lush and engaging, and the treble is smooth yet sufficiently extended to convey air and ambience.
Its tuning sits somewhere between a U-shaped and V-shaped signature, making it a rather safe choice overall, in my opinion.
Male vocals - 8.5/10
Female vocals - 9.5/10 (buttery smooth)
What stands out most is its ability to present orchestral music with realism and emotional impact rather than analytical dissection. Strings sound organic, brass carries authority, and large symphonic works feel immersive and grand.
Technical performance is strong, though the focus remains on musicality and coherence rather than sheer resolution.
Paired with the Mojo 2, the synergy is exceptional. If your priority is experiencing the music rather than analysing it, the Tea Pro SE is a standout performer.
If you also own a Moondrop Variations like I do, you’ll immediately notice that the Tea Pro SE offers a fuller, more natural presentation, with richer timbre, greater note weight, and a deeper, more holographic soundstage that makes the music feel remarkably immersive.
It also sounds better than XENNS Mangird Top Pro, yes!
Comfort - Hours can pass without the urge to take a break, without any fatigue.
I've been using this IEM for a couple of days now, and compared to the Moondrop CHU II, the treble feels noticeably improved.
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..👍🏻
One of the best iem in terms of balanced sound with slight new meta tuning. Vocals come clean with controlled bass. (Maybe sub bass could be a bit more but it's okay). Music separation is top notch in its class. Detail retrieval is also class leading. This is the point of diminishing returns. For many this could be the end game iem for sure.
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
