    Audio game step-up
    First impressions using this with my laptop, this boy loud... and the lowest volume is still pretty loud especially with a sleeping roommate, this has a night mode for that reason and it works pretty well. The box arrived damaged but then again it did just travel 7000 miles its pretty common for packages I get. The product box itself was flawless as well as the product. Its a little big for my current desk but that will change when I get back to the states. The bass is pretty good not as good as a stand alone subwoofer but for this size it is acceptable. The virtual surround sound is pretty good for a stereo speaker makes a big difference for everything I listen to. The speaker its self gets very loud, louder than I will ever need. I have only found one problem with the speaker so far and that when you turn up the speaker volume on the bar itself and listen to audio there is like a static sound but I have only heard that once and haven't heard it since but I felt like I should mention it, update it seems to only be a problem whenever I have TruVolume on also another problem I have seen is that when I pause a video for a while and then go back to replay audio there will be no audio for like 2-10 seconds until the speaker starts playing audio its perfectly in sync its just a delay between when you get audio this got to the point where it is actually very annoying so I decided to try to fix it and I believe I did, if you're using this with a laptop you will probably have two options to select from in your device playback just select the Vizio one it has little to no delay like I stated before and I haven't noticed a drop in audio quality just a huge boost in QoL because now when I hit play on a youtube video I had paused I get sound instantly rather than 10 seconds later. For the price this thing is a beast I feel bad since I'll never be able to see its full potential due to living in the barracks but I use it for Youtube and music mainly and it does that well.
