They hang in my ears better than any other earbuds I have tried. Have been using similar products for years, and this EPICKA Universal Travel Power Adapter is the best so far! I tried these Mary Janes in two sizes, one in my usual shoe size and the other in my athletic shoe size which is a half-size larger. The soundstage on the chinese/MKII is muted, muffled, indirect, muddy and cheap sounding. They have been WELL designed and the materials are fabulous. Now I have to buy another cause this one is cheap and garbage. ***July 2019 update***16 months (give or take) since my first review and I am back to support the initial 5 stars I gave it overall. As someone who is a sound technician, band member and tech fanatic my collection of sound gear starts from anything from free apple headphone to a £2000 pair of headphones and a full kef and sonos sound system. Recently I purchased a gorgeous peacock blue, knee length winter coat from a thrift store. I have had these headphones for about a month, and I am content with my purchase.
