Not too sure with Fitear offerings, but from my experience with Naobi and Yatono I do hear a noticeble boost in technicalities, especially in resolution and soundstage width. You are accompanied with a darker background as well, which does favour to sensitive iems. To me the LE version will do...

If you need both I would probably say ibasso DX MAX series/Cayin N30LE AP.

I guess the only way is trial and error. I am personally more susceptible to 8k, while many folks here dislike too much 6k. I guess you can play around with eq, learning the basics of eq definitely elevated my experience in audio.

1. Subtonic Storm. Crazy that Subtonic had never entered the Chinese market. I mean, you can't find a SINGLE impression/review on chinese forums, given its popularity in the west. If they promoted in China guess 300 Storms could be sold at 10k within an hour. 2. Beat Audio Orbit Saga. Yes...

Thanks for the impressions! Do you find it portable? It looks pretty big. And do you know the expected price? I heard it is going for 20000Yuan (~2550USD).

I actually find them to reduce treble and smoothen treble peaks, but yeah I agree they smoothen things too much sometimes.

Final E tips supremacy. Sturdy, comfortable and cheap.

Its been some time since I heard the EXT so I can't really comment on that; but from memory it sounds pretty warm to me, and is VERY power hungry: Still one of the most power-hungry iems till today, the opposite of Phonix, Aura and VEX which are considered pretty sensitive. I personally thought...

Agree with the 16khz spike, an issue to me as well. Common phenomenon found in 64 iems - tia brought a wide stage, though with occasional spikes. Can't really regard it as a 'problem', guess we can only live with it. I agree with @Deezel177 comparison - jewel is more neutral, while notes float...

I doubt if VEX is an upgrade of A12t. To me both have similar technicalities, just different in tuning. 12t is mild U-shaped, while VEX is warm neutral. VEX sounds more relaxed and has better bass slam, while A12t presents music in a more 'organized' way. And Phonix sounds pretty different from...

No. You still have to access streaming apps via BT or USB.

Agree with @Anlan Dong on this one. To me cables are about preference, and synergy is the word I am looking for. If portability isn't a concern to you than Brise cables would even do more justice to you . Shiro is pretty supple, Yatono is soft yet stiff: Great sound, but got irritated over...

Which Brise cable did you find to go well with U12t?

I find them similar yet complementary in some way. 6t gives better bite on vocals because of 1) thicker lower mids and 2) lack of the 4k dip, while 12t gives a better overall soundscape. 12t still tops my (and many others) list till today, just can't get over its vocal presentation if I have to...
