The Sony XBR X850F features a new overall design. The first noticeable changes compared to its predecessor is the new design of its stand.

With the Sony X850E that uses a centre stand, the X850F features a two feet stand that’s tilted at an angle. These stands are designed in a way to fit the all-new Sony Soundbar 2.1ch Dolby Atmos®/DTS:X™ HT-X9000F. This soundbar is actually designed to be a perfect pair with the Sony BRAVIA X900F.

Furthermore, the stand now features a cable management option. You can use the back of the stand to hide cables and hold them in place with an included cable holder.
