I bought them around a month and a half ago and they were great until I noticed this happening. Is there a way to fix this? I've tested it on multiple devices and I'm certain that it's the IEMs that are causing this. Should I contact Amazon or Moondrop directly in the case of a refund? Thanks!!!

There is no single review about it cuz it's new. so I wonder any of you guys brought a new CHU II? Is it better? I don't care about bass. I only need to know is, Does New CHU 2 have better Resolution, Details, Separation, Soundstage Imaging technicalities than the classic CHU?
