Did some Ninjas got into your home?
Hahaha. I seems to be unknowingly collecting portable headphones for some reason. I have the ESW10JPN now and also the ESW11LTD incoming. Heard the Momentum and I know I have to get it as well. They are not the last word in SQ and certainly custom iem and full size headphones can overtake them in SQ when used in a proper setup. Yet, they are value for money and are convenient to use.
I am looking at the Centrance M8 and Apex Glacier as well. Have you heard them?
