Return to Full DiscussionV1199932yThese headphones are way too heavy on the highs - like an AM radio. I tried 16 hours 'burn in' but still sounds awful. Do a search on these before you buy. Price is cheap because they are cheaply made and sound cheap. Better off paying top dollar for a premium product. Left them out in my office for someone to take but no one wants them. ebernal22yV11999I'll take them lol itahn12yV11999but burning is more than 100 hours straight... i heard that is between 200 up to 500 hrs straight burning... redtide02yV11999check out phonon 4000 or smb-02. Insanely good for the price. a lot of rave review. mdjhz02yV11999100hr burn in plus leather pads make all the difference Drewmuz12yV11999I used a digital audio player couple with a digital to analog headphone amp and I had wonderful results. These headphones produce quality sound when their is a quality source. AM radio? I'm not sure I would use anything priced over $10 to listen to AM radio.
