I had the x31 but recently bought the x12 because i hated putting batteries in it and i would have to say that the x12 are three times better in sound improvement.

i would say x11 there really good i dont think you would need anything better

i have both and i must say the x12 sound WAY better due to bass boast just keep the bass at full and they sound wonderful. but the x11 are good too so get whichever one you can afford.

x12 are a new version of x11 but they put 50 mm speakers in it instead of 40 and they are cooler looking and the same price

I've had my x11's for over a year and there still going strong. Longest lasting mic ive had yet. Plus there wired cause im not into charging batteries constantly.

This is why you should get the x12 instead of the x11
