Saiyin Sound Bar for Smart TV, 31 Inches, Detachable Soundbar Home Theater Surround Sound System for TV/PC/Gaming/Projectors,Bluetooth 5.3 TV Sound Bar with TV ARC/Optical/AUX/Wall Mount

Needs a volume normalizer
Good soundbar but why don’t they add a volume normalizer for these, have to play with the remote to adjust very high or very low volumes.

But it
This sound bar is awesome. I bought it hoping my wife would like it and she loves it. Excellent sound and you can make it surround sound….. it’s ok.

Six to Nine watts per channel.
I tested this unit in bluetooth mode, and I must admit, it works very well in the sense that it connects willingly (to a Samsung phone) and maintained a solid connection from 25 feet away, from a different room in the house. Not bad! I’ve had many units do worse. I listened to some rock music (America: Riverside) and classical (Brahms: Requiem, and Beethoven violin concerto, Jochum) to judge the sound quality. Result: the unit has a clear midrange, a surprisingly adequate bass, and a subtly but oddly irritating treble, probably due to treble distortion. But sound was loud and free of rattles and gross distortions. I would say the sound was fairly typical of some Class-D amplifiers I’ve heard. Now to the real issue: the claims of “90 Watts Speaker Power” — this is complete bunk, as you can see from the power adapter, which is rated for about 24 watts. The Law of Thermodynamics says power out is always less than power in. I think this unit produces about 6-9 watts RMS per channel before gross distortion begins. However, consider the speaker design: the main sound producer is a treble horn, which is extremely efficient, and the parallel wired 1 inch diameter voice coil bass-midrange speakers with the 1.5 foot sound column are a fair match. Efficiency means that low power produces lots of sound. The designers did a decent job squeezing every last penny of value out of the manufacturing process. Quality control might not be great, though. You can see in the photo how the speaker grille on one side, near my thumb, is not actually installed correctly. This might have caused a rattle if I had not noticed it. So, how do I rate this unit? Well, it’s NOT any kind of audiophile unit — and considering the speaker size and being a class D amplifier, it can’t ever be, technology being where it is now. The seller says, “excellent audio quality and impressive audio-visual effects” but I don’t think anyone is expecting audiophile quality here. Also, class-D means that you likely cannot use this amplifier to amplify an AM radio — you probably can’t even operate an AM radio within 25 feet of it, due to radiated hash. In my opinion it is the responsibility of the seller and the manufacturer to tell the customer this. Also, the insane power claim. But — this unit is perfectly serviceable for, say, a children’s TV, where sound quality and small size matter. In this respect, the unit’s versatility makes up for a LOT, having so many ways to connect to it. So all in all, it’s a mixed bag. I think I would normally give this unit 4 stars, indicating that it is largely suitable for purpose and worth buying. But I must subtract a star for poor seller or manufacturer integrity, for (1) making the absurd 90 watt claim, (2) hiding the fact that this is a class D amplifier which is bad news in the close vicinity of any AM receiver. So, it goes down to 3 stars, indicating “significant issues found”. But the amazing versatility, connecting to all these kinds of sources, is a pleasant surprise, and I award it an extra star for that. So, it ends up at four stars. This unit is worth buying — but be realistic about your quality expectations, and I would suggest comparing it with other similar units first.

Wow, this is a great sound bar for a reasonable price
I had bought a smaller sound bar of this brand about a year ago and it’s been great. I saw this one and how it can be used as a single sound bar or be split into 2 separate speakers for a more emersive sound and decided to give it a try.I had hung my original sound bar of the front of a hutch we have in our room and it looked small and took up very little space so I was very pleased when I hung this one in the same location as a single unit and it took up the majority of the space because it looks so much better in the location.We don’t use TVs anymore because I find projectors to be far more practical and cost effective being as they take up less space and give you a much larger picture for a fraction of the price so having this be BT capable is a huge bonus since I can connect it to my fire stick and have quality sound for all the movies and YouTube channels we watch.Eventually I will be setting up a better layout for our projector and then I will split the soundbar into 2 separate speakers because apart they really give an emersive sound experience but due to our limited space at the moment I choose to keep them as one unit and I can’t complain at all about the sound. It gets loud when you want it to and stays crisp and clear except in the highest of volume settings on the controlling device which is expected since any sound system can become overwhelmed if pushed to be.This brand of sound equipment so far has been impressive and if very good quality. I believe my smaller soundbar from them is a 20″ and I plan to use it with one of my projectors for a mobile theater so we can enjoy watching movies outdoors to get that drive-in experience feel.
