Have been happy with my buds
I have had a pair of Mifo earbuds for about 3 years and they have been a great in terms of sound but not good in terms of microphones for calls. I have the ones in a metal case and am so pleased I am ordereing some new ones (apparently with a better microphone) after losing one of the buds. Admitedly I have not had to contact Mifo so don't know what the customer service is like.
