I'm French. I live in french. I have nothing to win by making any advertisement. However, as a music lover very interested in earphones for a long time, this website is one of the most accurate i know (not to say the most). Here is the top ten :

It's truely reliable. Some brands like Shure or Westone are not famous in the public industry. But don't make a mistake by going to by more commercial crappy earphones like the Beats one ! I say crappy in terms of comparison. The Beats etc...are not bad, but they are way far behind professional ones like those sell by Westone and Shure. It's those earphones you can see in the ears of music stars or people on television etc.........lots of technology behind (multiple drivers, subwoofer systems etc.......)

Others websites may compare earphones, but this one again is the best IMO. I remember i had bouht etymotics ER6i after following advices of a website saying it was so good blabla. It had NO BASS. I just couldn't stand it. I like balanced sound with all the frequencies represented. I then discovered earphonesolutions and was able to see how the er6i was clearly famous for not having lot of bass etc.......This for the little story...........anyway trust me guys if i'm like you owner of a HTC M8, with HK mod and Viper4android is that like you i like good quality sound in my ears........
I don't talk about ordering on this website ! I'm talking about getting the best earphones possible depending of the money you can spend. Then order it wherever you want !
I bought stuff from this site before. Good selection and service for quality gear
