I purchased these due to wanting a wireless active noise cancelling earphone after having experienced discomfort with any in-ear earphones. These have been phenomenally comfortable, albeit at times feel like they may fall out (have never actually done so). The sound is phenomenal and the ANC is decent (I have nothing to compare it to though). That said, I did find that whilst there's a good range of tips that these come with, they don't hold a candle to Comply tips. Buy a set of 500 size Comply tips and swap them on if you buy these.
