Gravastar Mars Pro Bluetooth Speaker Review

Finding the right amount of volume to enjoy your music to is all the more easier thanks to the Mars Pro’s Touch-sensitive Volume Controls. They even have LEDs for that groovy feel.
There’s a considerable amount of RGB on the shell and the legs. So once you turn the speaker on it looks even better. There is a Bluetooth and a battery level indicator on each side of the speaker. Along the top are all the relevant controls.
The weight of the speaker is made up of metal and the massive 2,5″, 20W full-range speaker with a 1″ high-frequency tweeter. This means the Mars Pro has an amazingly high-quality sound that is rich and loud.
I found the sound to be a bit bass-heavy, even in songs where there isn’t that much bass. I have no doubt people will enjoy the sound this thing produces, but it may find more fans in the bass crowd. The sound will always be crisp if it’s spotify, gaming, or watching The Batman.

Connectivity-wise, Mars Pro uses Bluetooth 5.0, pairs with devices near-instantly, and suffers little to no delay in its effective range. The battery can go for 15 hours, give or take, depending on multiple factors such as the volume and RGB.
Overall, the Gravastar Mars Pro Bluetooth Speaker is a great desk speaker.
