when i put them on and starting listening to music, right away i feel like a weird feeling in my inner ear and it feel uncomfortable. i dont get this with other headphones and i dont have the volume on very loud. is this normal for these headphone or is it defective?

When I plug them in my computer it's blaring loud. I have to set the windows master volume on 1% and lower whatever else im listening to also. I also tried them on my sister computer which has vista on it and still the same. tried it with the ipod and i can still hear the music even tho i set...
