just want to leave my experience with the KZ T1 TWS.
This is the worst UX I've ever had.
- The case is really heavy and opens extremely bad. I ripped the top part out.
- the case has L/R bud position switched, so you pick the right earbud from the left side of the case.
- the headphones feel and look cheap with the glossy finish. Should be matte plastic like Tiso i5
- Volume control is ****ed up, goes from medium to loud without in-between
- touch controll could be tuned better
- stupid old tones like from BT 4.0 China speaker
- Amplifier runs always 100% , the DAC output volume changes. Means more distribution on lower volume
Now the good parts:
- They are comfortable to wear.
- They sound extremely good with only AAC 256kbit . Like world's better than QCY T2C or Tiso i5. Better than KZ ZSN in good DAC. I used the T1 right out of the box! Normally I let most headphones to burn in couple of ours (cuz usually only the expensive audio is burned in already inside the factory) I have them for 2 days now and already want to keep those as dailys despite of the horrible UX around the earphones itself. SQ is just really nice.
The overall tune is more balanced than usual from KZ. I like it. The soundstage is not big, but the separation is awesome and makes up for that in good masters. I do relisten old songs and hear new tones . Such athmosphare in good masters. Really lively 3D space, even if not big. Overall they let some details through which I didn't knew before with my Takstar Pro 82 over head monitors and ES9018KM2 DAC.
You have really the feeling that they are limited by AAC 256kbit. Maybe I could improve that with custom Android ROMs , but right now they don't show SBC HD if the device supports AAC or better.
Overall I will rip the case apart and cut the housings out and replace left and right. So annoying . And this is nothing you would have to ask from public beta feedback. This is obviouse if you try to use it once!
