pro tip for all the audiophiles out there

pick up a pair of open-back headphones

I’ve got these ones (Sennheiser HD 650)

obviously other people can hear what you’re listening to, which is often the point of using headphones

still, they sound insanely good and you avoid the fatigue of in-ear / closed-back

This set has been a treat

I've Focal Elegia, no fatigue. About in-ear to me is more a problem of the fit, I'll go with a custom molded version soon for a better confort. 
Feel free to share casts in the /audiophile channel :)

The main disadvantage is that you can hear what's happening around you very easily.
