Input:
User Review: From the first time I put these over my ears and hit play I have been disappointed.

The brightness of the audio is EXTREME.  Very sharp highs.

On the bottom of the spectrum the bass is nearly non-exisitant.

I can hear the speakers distorting before I can even really turn them out to what I consider a loud listening volume.

I have tried these on 3 different devices(one being an amp to actually drive the headphones more proper).  Little difference between any.

After about 15-20 minutes my ears felt hot.  I removed to headphones to realize I was actually sweating.  I understand new $20 aftermarket ear pads will remedy this.

I left them playing music over night so they had a total of 20 hours of music playing through them, hoping they may break in.  No avail.

These are not what they are cracked up to be.  I am returning mine.
