I need some closed back (live with others) headphones for general PC use -- for casual music listening of all genres and PC gaming, that are comfortable and decently priced. I was also looking at the KNS6400, Sony MDRV6. and SRH440, but these two seemed generally cheaper and also very reputable.
 
Can I get some opinions on the two? Seems like the audio quality is better on CAL but the 439s seem very very comfortable.

The CAL! are clearly better than the HD439.

You should also consider Takstar Pro 80 (or Gemini HSR-1000 same headphones)
 

 

 
Best Luck!
