Yes, it say it is authentic.
-- I just switched tips to the small ovals and it seems like there is a larger difference now. I had tried them yesterday, not sure if they are oriented different but now it sounds better than the Sony's or my DIY ones (apparently there is not a good seal unless I really got them in good).
This makes me hopeful, but I'm not 100% convinced yet. There was no question in my mind before. Maybe I just need those properly fitting tips and I'm fatigued/ having a bad sound day.
Stress, tiredness and repititveness can cause that. I normally take 2 days break and everything is sounds Wonderful again. For me its mostly lack of sleep, which make everything around me dull. Psychoacoustics is very real.
Regarding the tip, these dont need deep insertion. Use a larger tip and try shallow fit.
