A few years ago, almost three to be exact, I reviewed the Future Sonics Atrio M5 earphones and I found them to be an excellent product. To this day my opinion hasn’t changed of them, I still grab them first even though I’ve got many others to pick from. Future Sonics though isn’t he type of company to leave well enough alone and they just had to go an improve upon on one of the best sounding earphones on the market. Aesthetically they haven’t changed, the internal workings have been improved with a new version of their proprietary drivers that offer a wider range of frequencies and just all around better specs. The set or kit I have today is the special edition that is green, this kit features packaging made from recycled materials  and a carrying case made from used rubber inner tubes.
