Hiwill Dolby Atmos 3.1.2CH Sound Bars for TV, Surround Sound System, 2 Up-firing & 2 Side-firing Home Theater Speaker, Deep Bass, 400W Peak Power, Soundbar with Subwoofer, eARC/ARC/OPT/BT, Nimbus A312

Good value
Really good value for money. Sound quality is better than I thought.

Ok but not great
I was surprised when this arrived at how compact the box was given that it contained a soundbar and a subwoofer. In the box you get the soundbar itself, the subwoofer, a remote control, batteries, HDMI cable with optional right angle adaptor (useful if you are wall mounting the soundbar), an optical cable, a jack to jack cable, and a power cable.
Setup is relatively straightforward – the subwoofer is connected to mains power – from the subwoofer there is a cable that then carried power to the soundbar and also the sound from the soundbar to the subwoofer.
You can connect the soundbar to the TV using a range of inputs but the primary ones would probably be HDMI if you TV supports ARC or Optical. I opted to use optical mainly because HDMI cables are bulky and hard to route whereas optical cables are narrower (but be careful not to bend too tightly). The included optical cable is absolutely fine, not sure why another reviewer was negative about it.
The soundbar seems to pick up whether the broadcast is using Dolby Atmos and decode accordingly and it does offer some element of ‘surround’ audio using the side and top firing speakers and whilst it isn’t going to be anything like that offered by separate discreet channels it is somewhat effective at being immersive. The sub is only 5″ or so and isn’t earth moving. It offers an element of bass at the bottom end but it is a bit “M’eh” to be honest. It absolutley is better than the TV speakers but it isn’t cinema quality by any stretch and for the listed price of £170 I was expecting much much more.
One annoying aspect is the very bright display that his behind the soundbar grill – there doesn’t seem to be any way to turn this off and it stays on for a very long time (sometimes always, sometimes it turns off after a while).
A bit disappointing overall – yes it is better than TV speakers but there are far higher quality options for the same price. This would be better priced around £80.

So getting to use this soundbar for about a week now. I had problems with it at first but thankfully the support from this company was amazing. There were quick to respond and with a solution. When you buy this guys, Important to watch for a message from the seller. They will provide you a message mentioning of a firmware you will need. And trust me you will want this firmware if you want this to work as intended.
The good thing about this soundbar is that is does deliver quality sound. Movies, Shows, But sadly trying to listen to music with. The sound is lost. Like the drums and such the deliver bass to your subwoofer. The bluetooth connection is good but I notice while your using the bluetooth connection. The soundbar auto changes back to E-Arc or Arc. And you need to change it back manually with the remote. Though I have tested it since the firmware update so many the firmware fixed this too. The build quality isn’t too bad it seems pretty solid. The subwoofer does have some pretty good weight to it so keep that in mind if plan to put this up on something and a fall could damage this. The value of the soundbar is decent and the $20 off was a great deal too. It was too hard to setup the soundbar but I would suggest reading the manual that came with it to hook it up properly.
Now as for the Dolby Atmos. I don’t think this is true Dolby Atmos cause when testing it with videos of audio that suppose to have sounds from above like jets, planes or helicopters. The effect to cast the sound above from the top firing drivers. But I can’t say for sure. I never had the chance to experience the Dolby Atmos but I’m sure it sounds better if it had surrounding speakers. But maybe it been better with a larger soundbar like longer bar that stretches across the bottom. Maybe I could be wrong. The black color of the bar looks ok.
The reason I have given this 4 starts instead of 5. Wish is worked good for music as well for the movies but the bass and treble isn’t the same as other speakers. I guess music isn’t built for surround sound but for TV.Movies which isn’t a bad thing. Overall a great sound system for the money you spend on it. But if want good music. Advice to get a dedicate speaker for music alone.

Note: I don’t know if the so mentioned firmware update (released on 2021, four years ago) is just an option or actually needed, I didn’t install it and so far I haven’t seen a need to do so.
Now, what you care about, my honest review:
Connectivity – In my case, it was plug-and-play, I turned the TV on and the sound bar connected automatically.
Sound Quality – You are looking at a less than $200 sound bar that claims to be “Dolby Atmos”, is it really? I don’t know, but the improvement in audio from the stock back/down facing TV speakers is worth what you’re paying for.
Presets – They do make a difference, specially the 3D option, which is the “Dolby” Surround one (it may be Atmos after all)
EQ – Is limited to just Trebel and Bass, there’s not that much difference, but I agree with other reviews that state the bass is thin, it really is.
Bottom line, at its price point, I can’t imagine a better option.
*No audiophile should even consider this bar, you have money for stuff that the “uneducated ear” like mine can’t hear or catch a difference in audio quality.
