Enthusiastic reviews

Satvision (issue 5/2021):

“The HDSX TV Sound Optimizer … achieves the top rating of ‘very good’. Significantly responsible for this is the fact that it completely fulfills its promise, namely to make voices more understandable as well as to eliminate sound fluctuations between different channels, content and playback media without cutting off certain frequencies.”

Süddeutsche (04/25/2021):

“The constant back and forth with the volume rocker is no longer necessary, and the best thing: Unlike the night mode of some soundbars, which simply cut off the volume peaks, you still don’t have the feeling as a listener that the sound is leveled here.”
