How do these filters on the PFE 022 work? Sounds suspect to me...
M4s can be found on Amazon, http://www.amazon.com/Brainwavz-Headphones-headset-iPhone-Smartphones/dp/B0068Z9YUS
This is the headset model with the single button remote and mic that is compatible with most Androids. If it isn't, you can buy the MEE adapter to make it work: http://www.meelec.com/MEE_TRRS_Adapter_for_P_Version_Headphones_p/adptr-trrs-35.htm
The reason you may need an adapter is due to the fact that not all phones follow the same right, left, ground, mic output order on the headphone jack. In some phones, the mic and ground ports are swapped which requires an adapter. To clarify, most Apple mics will work with Android (you'll just lose volume use, the center button for play and pause will still work) as long as the jack follows the same order (if it doesn't, you just get the adapter).
As for the 022, there is a tiny filter that goes inside the nozzle. When you buy filters, you are given a filter changer (which is a tool used to swap filters). These filters are disposable and allow you to alter the sound of the headphones. The 0xx and 1xx series use the same drivers, design, etc. The only difference is that the 0xx series comes with a green bass filter and the 1xx series comes with both the black (low and highs) and grey (mid-range) filters.
