After a very short time I now notice a crackling noise in the audio

No crackling noises in the mic as some people have mentioned.

They have a crackling noise when hooked up to my xbox, and so much static when hooked up to my phone.

I wrote a review on this mouse over a year ago, and it is still working as if it were new

He is honest when id comes to criticizing electronics as he is in IT, but I have not heard any complaints about it!

I suspect these headphones do not have a flat frequency response as they have a sharpness in the upper mid range as well as in the bass, much like pop and electronic for which they are very clearly contoured

And i actually prefer using the mini usb cables provided than plugging the whole light into my usb port as with the knogg design

but they did work as they said

I also run at night and attach the white light to my belt, it provides enough light for safety as well as to illuminate the side walk as I run

I Highly Recommend A+A+A+A+A+

The sound is great, the microphone holds up and he can be heard clearly, they remain comfortable over long periods of game play (3-6hours per day minimum) and the only hiccup he had is that he needed an adapter because his computer didn't have the right port(s), but once port-ed its been smooth sailing
