  • Great Sound at a Great Price!
Model: U3721
This soundbar is so much fun and I love the customization features. Plus, got it on Prime day at a great price. Very easy to install and sync. My previous soundbar only had three options and there was zero customization. Plus, this has 5 channel surround and Dolby which is currently the industry standard. My only issue? I can’t play it as loud as I’d like as the sound is so booming it freaks out my dog! lol. Thanks for a great product. ... show more

  • Love it!
Model: U2520
I put this in my game room. Easy setup and amazing sound for the price. Easy to connect to your tv or any bluetooth if you want. I plan on getting a couple more for the living room and bedroom. I was so happy i could get quality sound at a decent price.

  • Lots of features for the price, but the manual is lacking a lot of details.
Model: U3721
Excellent product for the price. Set up was easy despite the manual being very vague and having few details. The subwoofer was a brief challenge to get working as the TV sound must be set to PCM to complete the set-up...which is not mentioned in the manual. It's not a beefy subwoofer, but does create a good balance with the sound bar. Very good for smallish rooms. ... show more

  • Just buy it
Model: U3721
The sound quality is amazing. It was the easiest set up ever. Plug it in, turn it on. No programming or changing settings on your TV. The price cant be beat.

  • Best 5.1 channel true surround soundbar under $200
Model: U2520
The media could not be loaded. Amazing product. Loved it at this prize point. I am actually surprised with the surround quality, also working bluetooth connection. 1. Very neat and clean finish. Premium build quality. 2. Bass is superb. 3. Great for a living room or bedroom setup with TV as well as projector (I'm using with 4k projector in bedroom). 4. Sound quality is very soothing, delivering every deatil with precision. I have checked the surround quality on Bluetooth and optical fibre, both works amazingly. Highly recommend this product if your budget is under $200 (100% value for money). ... show more

  • Poseidon M60 (2025) will not turn on
Model: U3721
When I first received the M60 and connected it to my TV, it sounded great. I downloaded the app per installation instructions. When the app loaded there was an update required, so I ran the update. When the update completed, an error message appeared on the soundbar. I turned the soundbar off to recycle power, however, it never turned back on again. Ever. I tried everything. I called tech-support. They tried to help, by telling me to touch the on button and the volume down button at same time for five or six seconds, but that did not work either. Customer Service was really good about sending a replacement, but I am not very confident that the same thing won’t happen. I was really excited to hear the great sound from this soundbar and subwoofer. Too bad it broke for no apparent reason after the app update. If my replacement doesn’t breakdown, I will update my review. I really hope I can give it five stars when I get the replacement! ... show more

  • Amazing system
An amazing system. Very easy to set up, both with the actual device as well as the app. I was able to connect it to both my TV as well as my record player. So far it’s been about a month since I’ve installed it and no problems. The sound quality is great especially compared to my previous setup. Looking forward to years of use. ... show more

  • Great sound quality
Model: U3721
Just got it today and it sounds great!! I’m very happy with the way it sounds so far. Pretty easy to connect my TV and phone via Bluetooth. I usually don’t write reviews this quickly, but here I am. If the lasts for a long time without defecting then it will be a winner for sure.
