Another revisioned "new" product by akg.

Would you please make a comparison between K702 65th  and M4U1?

The k612 pro is a headphone worth mentioning too! I love it and for the price, it's rather an over-achiever!

Hello @ballard3 ! The K702/65 is a semi open headphone while the M4U1 is a closed headphone. The M4U1 will definitely isolate better than K702/65. M4U1 is for sure more portable than the K702/65 as well. Unfortunately, I do not have M4U1 with me right now and this is purely based on memory;
 
-The K702/65 offer better soundstage and imaging
-PSB M4U1 offer deeper bass and slightly more powerful
-PSB M4U1 is slightly darker
-K702/65 sound cleaner
 
Then again, I do not have PSB M4U1 to compare side by side with the K702/65. Above comparison is all based on my memory

stormmilk, you want new product? What about K812? Their new reference headphone.
