    "Love it...Pro tip!...I am a big Razer fan, but I usually don't buy their audio gear, because they tend to make bass overbearing, but they seem to have a really good balance on this soundbar....The bass is really good as well, although I will say, during moves I sometimes hear a rattling sound and I am not sure why."

    "Wow ....I love....I know BOSE is an excellent brand talking about sound, to be hones I was hesitating in getting this one since it is a small size speaker, I think for an apartment is a great speaker, not too sure for a bigger living room, but if you live in an apartment this is great, finally I can hear what they're saying in the movies, totally worth it...This is a Good Sound Bar, But not the Best Sound from Bose, I expected more Bass and Volume from a Top Tier Sound Company, I could have gone with a 5.1 Surround Sound System, Which I may return this Item and get the complete set up, I thought that this would have been a better speaker."
