It is rather frustrating for sure. Finally find a pair that sound super good and they have QC issues... I may try my hand at replacement first before writing them off altogether. I did get them off Amazon, and I read another post stating they stopped selling them off Amazon UK due to so many returns. It's unfortunate you have to essentially play the Hifiman lottery to see if you get a good one or not. I wish there was a Sennheiser headphone that had this same sound signature.

I'll have to look into the Moondrop Venus! I'll give your post history a look as well. It's been quite the adventure so far just trying to find the "right" headphone for me. I was convinced the Edition XS was it until I got buzzing noises. Maybe I'll get lucky with them and if not, try something else. Thanks again for your suggestions and whatnot!
