Choosing a soundbar is not an easy task and the Samsung HW-Q950T vs Vizio V21-H8 comparison is meant to help you with that. As a result, it is clear that HW-Q950T is much better designed and has a better sound performance than V21-H8. According to the results of our comparison, HW-Q950T received 8.4 points out of 10 possible, and V21-H8 was rated 5.5 points.
The HW-Q950T is rated 9 of 10 against 6 for the V21-H8 according to the audio features rating.
It worth understanding the difference between the two types of amplification: a passive soundbar does not have its own amplifier and receives amplification from the signal source, while an active soundbar has a built-in amplifier. The same active type of amplification is used in the HW-Q950T and the V21-H8.
There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound. It is worth noting one of the main differences, the HW-Q950T has 9.1.4 channels, while the V21-H8 has 2.1 channels.

Soundbars can have a built-in or external subwoofer. The first type is inseparable from the soundbar body, but for the second, you can choose a good location for deep bass. Both reviewed devices are equipped with an external subwoofer. Samsung HW-Q950T has the ability to handle wireless connections from an external subwoofer, while Vizio V21-H8 only has wired and wireless connections.

Unlike stereo, when reproducing multichannel sound, each specific direction of sound corresponds to its dedicated channel with a separate independent loudspeaker, which creates a three-dimensional sound stage. The HW-Q950T received rating 9 out of 10 for multichannel audio processing, but the V21-H8, in the same category, earned 5 out of 10 points.
The peculiarity of Dolby Atmos is that this format is object-oriented, that is, each object of the audio signal is sounded separately and linked to its spatial location. Dolby Atmos surround sound support is implemented only in Samsung HW-Q950T.
DTS:X is an algorithm for processing sound scenes by the processor, linking directly to objects, rather than channels, and calculating the optimal distribution of sound output in a room. The manufacturer has implemented DTS:X technology only in HW-Q950T.

The existence of a sufficient number of current connectors significantly expands the functionality of the device. For example, only through HDMI is it possible to implement the transfer of object-oriented formats, and the presence of a Bluetooth connection will allow remote control, etc. The devices received different ratings for connectivity: Samsung HW-Q950T was rated 8 out of 10, and Vizio V21-H8 was rated 6 out of 10.
The presence of Wi-Fi in the soundbar allows you to get rid of wires when connected to a sound source and get minimal audio latency when playing content from streaming services. Wireless connection via Wi-Fi is possible on the HW-Q950T.
Bluetooth connection is now one of the main communication protocols for speaker systems, which provides excellent quality and minimal audio latency. The availability of Bluetooth protocol, we can see in both models. The HW-Q950T has 2/1 HDMI inputs/outputs, but the V21-H8 got 0/1 HDMI inputs/outputs from the manufacturer.
HDMI ARC is a very usefull technology that creates a two-way communication channel between a TV and another device. This is convenient since there is no need to use optical and other cables in the system. HDMI ARC is basic for both soundbars. Connecting external devices via USB can be done on both models.
