In use HIFI, no joking tone, he misses the spectrum of acute, stereo feeling cramped space, no present and serious aérée.Les soundstage are present, but lacks body.
TV In use, the use for which it was designed, again, big disappointment.
The voices seem indeed put a little more forward, but the listening pleasure is absent.
Test on a panasonic plasma that has an excellent section dedicated to electronic headphones (heard with an HD 598 reference) the sound is deplorable and unworthy of the range of previous TV Sennheiser headphones.
It's incomprehensible that design flaw given the asking price and a large part can be attributed to the extension 5 million and 2 channels of independent settings.
Comfort seems attractive at first, but warm weather, leatherette ear cups do not promise hours without sweating.
The problem is that I looked for a moment the replacement for the HD 408, which was perfect for the TV use, but does not find anything else !!!
