The cable on the M50s is 3 meters long, way to long to hear music from  phone.   Would you guys aprove to cut the wire 3 inches away from the headphone itself in order to install a 3.5mm female jack or would I lost a lot of sound quality?

I'm waiting for my ATH-M50s and I'm looking for a method to shorten the cable as well. I'd love to have a female 3.5 plug so I could just plug any lenght of cable I need at any specific moment.   However I'm concerned about loosing any sound quality because of that.   Has anyone done it...
