This headphone has been found / bought in mid 2k's from an audio equipment store , of a friend's for a cost of ca E30
The design is similar to other AKG's design with adjustable headphones and a belt to keep the head. The cable length is very similar to other's length ca 2.5 m and 1.9mm thickness stereo plug . each headphone covers your ear with a slightly rubber sense.
Using it on computer the sound is excellent -Cd quality - especially with Soundblaster. Until last year 2011 when i replaced the old computer with a new, when i used its built in audio card . this new configuration lacks some clarity , tough still the sound is quite good.
Now the test: - comparison with other headphones- :
Comparison with Sennheiser : the Sennheiser is quite bassy., This AKG sound bassier
With AKG 512 : 512 is slightly bassier than 66 with same clarity with 66
Koss UR20 : lacks all basses !
Carrfour mini ears : same with Koss !!
