Picking the Right Onn Soundbar For You

How do you pick the right soundbar for your home viewing? This can be a bit of a difficult question to answer, so let’s instead take a look at some considerations. When picking a soundbar, you’ll likely want something that readily integrates into your home theater.

However, not all soundbars are made equal. So, you’ll likely want to keep an eye on a handful of features. These are as follows:

  • Input Ports
  • Audio Codecs
  • Overall Power

Input Ports

Now, input ports are a very basic thing to keep in mind. This is what actually delivers audio to your soundbar. That said, most of the basic offerings from Onn don’t have great input options. As such, it might be worth looking at some of the options over $100 to get HDMI inputs.

The reason you want to aim for HDMI inputs for your soundbar is so you get less overall compression and better sound quality for your viewing experience. HDMI has higher throughput, so it delivers more data at a faster rate than something like an analog auxiliary connection.

Audio Codecs

Now, most of the featured soundbars aren’t going to have great support for the plethora of audio codecs in use by modern TVs. This is to be expected, as Onn mainly creates soundbars for a certain price point. However, they do provide some options with Dolby Atmos support.

As such, you might want to opt for one of the more expensive soundbars if you’d like to move past simple stereo audio. Soundbars aren’t going to give an accurate portrayal of spatial audio, but they do a fair job.

Overall Power

Soundbars come vary greatly when considering power consumption.


The overall power output of your soundbar can reveal quite a bit about how detailed the audio is going to be coming from the speakers. While higher-quality soundbars generally use more power, it is important to note that more power isn’t necessarily indicative of higher-grade speakers.

Also, you will want to check your electrical system before using a high-output speaker system. Soundbars can use a lot of power, and if you’ve got an older home it might be a concern if you’re not wanting to trip the breakers.

Using a Soundbar: What Is It Like?

Using a soundbar is like using any other sort of external speaker. You’ll need power and a reliable connection. Soundbars are a great choice because they have a much more compact footprint than a set of speakers for surround sound.

Onn soundbars typically come with optical audio or HDMI inputs. Also, most Onn soundbars have Wi-Fi or Bluetooth wireless capability. As such, you can sync it up to a compatible TV and get rolling in no time. You will have to control the volume separately on a soundbar, however.

Onn soundbars aren’t going to top anyone’s list for the best soundbars on the market. Despite this, they are perfectly functional and might be a better choice than the poor speakers found on many TVs. Walmart has a fairly solid return policy, so you could always swap it out if it doesn’t suit your needs.
