The HT-S400 is great at creating a surround sound experience. Using Sony’s S-Force PRO Front Surround technology along with Dolby Digital, the system makes it feel like sound is coming from all around you, just like in a movie theater. In addition to its surround sound, the HT-S400 uses advanced audio tech, including the X-Balanced Speaker Unit and Separated Notch Edge.

The X-Balanced Speaker Unit has a unique rectangular shape that makes the speaker diaphragm bigger, which helps reduce distortion while keeping the sound strong. This design improves vocal clarity, so every word in movies or shows is easy to hear. The Separated Notch Edge also helps by improving sound balance through small cuts on the speaker’s edge, which manage pressure inside and outside the speaker for cleaner sound.

The soundbar also comes with a strong wireless subwoofer that has a big 160mm speaker unit, which adds a lot of impact to action scenes and music. Since it’s wireless, you can place it anywhere in the room without dealing with messy cables, making it easy to get the best bass response.

The Sony HT-S400 is also very easy to use. It comes with a simple, small remote that has buttons for adjusting volume and sound settings. There’s also a handy OLED display on the soundbar that shows information like the input source, volume level, and sound modes like Sound Field, Voice mode, and Night mode.

Setting up the soundbar is simple, too. You can connect it to your TV with either an HDMI ARC or optical cable, making installation quick and easy. This single-cable setup reduces clutter and lets you start enjoying better sound almost right after unboxing.

Right now, the discounted price of $178.00 on Amazon is a big opportunity to get a high-quality Sony soundbar that delivers surround sound, clear dialogue, powerful bass, and easy controls. The 41% price drop from $299.99 makes this feature-packed audio upgrade more affordable than ever, but it won't last long.
