3d sound sennheiser

They use virtualization and upmixing technologies that create virtual speaker channels and convert stereo or 5.1 sources into a 3D soundstage.

Listings show channel configurations such as 5.1.4 and 7.1.4.

Some models deliver deep bass without an external subwoofer, others include built-in dual subwoofers, and several offer wireless connectivity to an external subwoofer.

They use automatic room/self-calibration (often via a supplied calibration microphone) and companion apps. Self-calibration algorithms measure room reflections and adjust speaker allocation and EQ to tailor the sound to the room.

A companion Smart Control app plus built-in equalizer, presets, and multiple 3D modes let you adjust acoustic settings and tailor the sound.
