Package

Standard KZ/CCA package with almost no acessories. Just the pair of IEMs itself, 3 pairs of eartips and the cable

Sound

Bass - Strong but clear

Subbass focused with superb texture, midbass is a bit recessed (for a V-shaped) but still have good enough weight to bass guitars and kick drums to not sound dull. Bass decay is on the faster side, so it isn't that looser

Mids - No bleeding at all

Very well articulated with not that distant or too close vocals (vocal lovers should look elsewhere), the instruments are nicely detailed and well separated

Treble - Insane extension for 15 USD

Cymbal are crispy and eletric guitars are very lively, sometimes open hi-hats can extend a little more than desired but for me it doesn't bother. Sibilance can arise in some tracks but I think this more depend on the recording itself than the IEM (old recordings specially). This level of treble performance is amazing, considering the old KZs with weird 2k and 4k peaks (hello EDX)

Is Worth It?

Absolutely, if you want a V-shaped set with deep bass and extended treble, but if you are a neutralhead or vey treble sensitive you should stay away from this set

Package

Nothing much to write home about, just the IEM itself, cable and three pairs of eartips

Sound

Bass - Big midbass but well placed

Good bass impact, without being too boomy and slow. Average decay and attack with little subbass roll-off, not that much looser kind of bass thanks to the upper mids peaks, texture a bit lacking but okay for the price

Mids - Warm and open

A little harsh kind of mids, sometimes very unforgiving with old and poor mastered tracks. Besides that, very passable and okay mids performance for a 7 USD IEM

Highs - Crisp and vibrant

Good treble extension and details, sibilance can show up sometimes but not a big deal. Cymbal crashes are occasionally very harsh for my liking, but if you are a low volume listener it might not bother

Still Worth It?

If you are tight on the budget and want a brighter V shaped IEM, certainly yes. But if you are sensitive to shouty upper mids, maybe the TRN MT1 or OG QKZ VK4 are better deal for you, and if you can stretch the budget a little more you can get a lot better options (CCA CRA, 7hz Zero, Moondrop Chu, Tripowin Lea)

Package

Very well done package for an IEM at the time of release, with a nice selection of eartips. 3 pairs of coloured eartips (vocal focused, it makes the T1 more shy sounding) and another 3 pairs of black eartips (balanced ones, I find these a lot better)

Sound

Bass - Thicker but well controlled

It's well extended and with good body, never sound anemic or boomy, it's more on the polite side of fat bass. Not that great with rap, hip hop or EDM kind of music, it might sound flat and boring with heavy subbassy tracks but okay for the most genres (nice texture btw)

Mids - Weighted with good vocal reproduction

Lower mids got ample body, instruments are nicely detailed and vocals are forward most of times but non shouty, this is the best part of T1's frequency range in my honest opinion

Treble - Laidback, Yet Detailed

You can hear the details in the treble, but aren't "in your face" kind of presentation, cymbal crashes are a bit shy for my liking (not most of times) but it's okay for this kind of relaxed tuning (I'm a V shaped lover). For rock it doesn't work for me, maybe with classic rock it works better

Still Worth It?

I don't think so, since nowadays you can find better options of this kind of tuning (Tripowin Lea, KZ CRN, 7hz Zero). But for the value that I paid (7 USD), it was almost free (I bought it last year)
