Are these headphones any good?

I found a pair of headphones in a box at my sisters they are Sony MDR-CD380 and i don't know much about headphone specs to know if it is good or not.

Here are the specs i found on sony's site:

  • Cord : OFC Litz cord, single-sided, 11 1/2 feet (3.5m)
  • Diaphragm : PET
  • Drive Unit : 40mm Dome type
  • Frequency Response : 10-25,000Hz
  • Headband : Self-adjusting
  • Impedance : 40 ohms (@1kHz)
  • Magnet : Neodymium
  • Plug : Gold-plated, straight stereo mini plug
  • Power Handling Capacity : 1500mW
  • Sensitivity : 104 dB
  • Type : Closed, Dynamic

And i must say one thing i know that they are better than my logitech G35 headset.

Oh and one more question,with these would there be a noticable difference if i got a asus sonar DG?

I am currently using my sabertooth 990fx's onboard sound.

they look pretty damn nice to me, but i'm not sure they're the thing for gaming. I think they'd be great for just listening to you ipod or mp3

Well i have not tried gaming yet,but not only does music sound better than my g35,but i found this site(http://www.audiocheck.net/soundtests_headphones.php) and tested them along side my g35 and my g35 lost lol.
