Usually, you buy the Insignia brand and expect a mediocre product, as shortcuts are taken and price is considered before quality. Not so with this Smart Speaker; Best Buy's contract manufacturer has figured out how to make it inexpensive and be a high-quality product. I have other Google Assistant speakers in my home and while they're good, this one is honestly better in many respects.
It was purchased under the guise of being an alarm clock and a Google Assistant speaker for the bedroom, with a focus more on the fact I picked up for a few bucks more than a regular alarm clock than anything else. So imagine my surprise when I connected my iPhone via Bluetooth and experienced excellent bass and treble response, especially for what I paid for the speaker. The sound quality isn't as good as a dedicated mid-range BT speaker or a high-end speaker with Google Assistant or Alexa in it, but it's actually a step up from two speakers I own that directly compete with this one.
Setup is super easy with these speakers, just like with any other Google Speaker. You'll need your iPhone or Android device with the Google Home app installed to get it going, Once set up and connected to WiFi, you'll be able to say "Hey Google" and have it do pretty much anything you want a smart speaker to do; the only thing 3rd party Assistant speakers don't do that the actual Google Home speakers do is make phone calls, but chances are you won't miss that feature.
Audio quality is good from pretty much any source. I tested with Bluetooth and Pandora, and both were crystal clear. You can also use Google Play Music, YouTube Music, Spotify, and Deezer (some services require a subscription). Chromecast Audio is also built in, so it can be a target for Chromecast Audio-compatible apps. It's only when you get to the upper limits of the device's volume level that you get audio distortion.
Other nice features are a display on the front of the unit that shows a clock, outdoor temperature, volume level, and even the outside temperature; USB port for charging your phone or other device at night; touch controls for those times when you can't say "Hey Google, mute the music"; and a pleasant, modern aesthetic to the device's design. It also has dual-band WiFi connectivity to connect to your network with.
If there's a drawback to this speaker, it's that it uses a wall wart instead of an internal power supply. That's not really even a con though, that's me nitpicking.
All in all, the Insignia Voice Smart Speaker is a terrific value for what it is. I'd recommend it over most of the major brands, unless you need a water-resistant speaker or want something that will give you a hi-fi experience, in which case there are other options. But for a speaker that will sit by your nightstand, in your kitchen, in your bathroom, or somewhere else that a small speaker that responds to your voice makes sense, this is perfect for the job.
