I've had the Noble X for a couple of weeks and held off doing a review. Out of the box using the supplied ear tips and single ended 3.5mm cable; I would have given these IEM's at best a 2.5 rating.
I made a few adjustments to the Noble X.
Switching to the Comply T500 foam tips made a significant improvement. Still the music was a bit too light in the bass for my liking. Doing a comparison with my Cardas A8 ear monitors proved this to me.
I ordered a Surf Cable IEM Balanced to Pono cable. Going balanced mode made a big difference in the sound. Fuller bass and more detail in the mid range too.

With the new foam tips and balanced cable, I'd say the Noble X approach the sound quality of the A8's.
With the changes, the Noble X are a 4/5 star.
RT.1128I have always been confused as to which Surf cable to buy to use with my Pono Player and Westone W50's, or Shure 215"s. Both use MMCX. HELP!!??!!
