So out of curiosity I ordered a pair as well, and so far I quite like them. I was a bit worried about comfort, but I find that the medium, narrow bore tips to fit my ears well.
@MarcosCh, if I were to describe the surface of the silicone tips I'd say that they feel a bit like velvet, quite different from my AirPods Pro but not in an unpleasant way.
Another worry was the sound profile, and I found that to be good out of the box well. In my opinion though, the EQ by
@Maiky76 improves things by extending the low end and making voices a bit less nasal sounding - I ignored the last two filters though as I can't hear any difference using them. But with that EQ applied I still find the sound a bit prone to sibilance, so I will try to put in a shelf filter or something going forward. I don't really mind the level of bass myself, even stock, it's just that some music simply has too much of it in the recording. Using Maikys EQ I find the overall sound levels to be similiar to my main stereo rig, and songs with bloated bass come across as bloated using the IEMs as they do on my stereo.
I do have a gripe, but I guess it isn't really the fault of these IEMs themselves, but rather that it is just how passive IEMs are. It has to do with the sensation of using them, the soundstage with music is literally between your ears and since they dig so far down low it feels like your head is pressurized when you listen to bass heavy music (try listening to some of the songs from
this thread for example). My AirPods Pro (both v1 and v2) seem to work differently with bass heavy music, and don't give the same pressurising sensation. I don't know if this is because they don't dig as far down as the TCZ or if it has to do with the ANC, but I feel that the soundstage phenomenon is more or less the same between the two.
I don't mind though - I don't listen to music with synthetic bass that often, and the soundstage isn't really a problem for my use case which is gaming. A lot of games use HRTF so the soundstage doesn't feel closed in at all, in fact, playing games using these worked very well, the deep bass and crisp highs made me hear some things I haven't heard before in the games that I tried. For example, simply walking down a street in Cyberpunk 2077 was very immersive experience with a lot of ambient noise that simply sounded very real to me. I think that the TCZ are going to replace my HD600 cans that I've been using for this up until now.
Lastly, the packaging ("artwork" aside) and the IEMs themselves feel rather premium. If you had shown me the packaging without the prize I would have guessed the price to be a lot higher. Let's just hope that they don't break.
Definitely happy with the ~40 bucks I spent on these, just gotta buy a longer cable as I am not using these on the go.
