The hardware demands for 90% of the tasks people use their phones for is fairly low. Although its too long for working out, I can deal with it because the cord NEVER TANGLES. Assembly did take about at least 20 minutes because there are many nuts and bolts to attach. I got the pink ones and cannot get over how cute they are. These are all rubber so they won?t get stinky after wearing everyday in the hot sweaty feet summer. It blocks noise and you can accept voice calls through it with no problems. I am very pleased with the quality of this. the sound quality was terrible and after an hour of putting the ear bud ring around my ear had to remove it because it started hurting. The imaging/sound separation and mids is now FANTASTIC and really reminds me of AD900. I decided to size down, but since there are not half sizes they are little tight.
