Just received the T1X and took out some of my earbuds again.
The T1X has a lot of Positives: usb C, smaller & classy case, great isolation, touch controls.
Although the treble is clearer, I find the T1X voicing recessed, slightly veiled or distant. A deeper V sonic shape if I may. It lost the throaty voice of Joe Cocker ("you are so beautiful guitar version" ). The overall vol is also ~20% lower than mpow M5. As such, the sonic quality loses impact and power which is often not mentioned in earbuds but only in amplifier reviews. In summary, the weak voicing is what left it wanting.
I find Spunky beats voicing is at the other end of spectrum being a bit too forward and shouty - OK at lower vol, shrill at loud vol.
That said I even prefer the voicing of SSK.
To my ears, Mpow M5 and SSK are still my personal star performers. The Bose 700 in the center is feeling shy.
I agree folks may have different ears.
If you can get hold of the SoundMAGIC TWS50 I would be interested to know how they do against the SSK
