This system really exceeded my expectations. Setup was quick and easy thanks to clear instructions and even a video guide—which I especially appreciated since I don’t always feel like reading manuals. I was skeptical about the small speakers, but once everything was connected, the full surround experience was amazing. What impressed me most was that everything came pre-paired from the factory. All I had to do was assemble the sound bar, connect it to the TV, and plug everything into the outlets. The remote is simple yet includes all the functions you need, and the system automatically powers on and off with the TV—no juggling multiple remotes. On top of that, the company provides a phone app for extra control. The Bluetooth connection to my phone works flawlessly, making it easy to stream music as well. I initially didn’t expect much, but I needed an affordable wireless home theater and decided to give this one a try. I’m glad I did—it delivers excellent surround sound, a great price, and none of the hassle of running wires. I haven’t noticed any audio delays, and so far the performance is on par with wired systems. Overall, I’m extremely happy with this purchase and highly recommend it.

Yeah, so, thing system is really good! Setup out of the box was easy, everything connected without issue. The sound is incredible!! Excellent voice isolation, I could hear crystal clear voices from over 40' away! Bass is deep and penetrating. The different audio modes do a great job adjusting the sound based on what you are watching. I thought I was low balling my room with the X50 but this thing fills the room with deep, rich sound. So impressed!

Great value, more sound than you’ll ever need (in a good way), elevated look, iOS app works just fine, absolutely zero interference/chirps/crackling that you’ll find with higher priced brands, setup was simple, even the packaging was well done. I’ll be recommending this brand to others, and will purchase from again for other setups in the future.

This Skywave X50 system exceeds every expectation I had and delivered even more. The Atmos is exceptionally well designed and truly envelopes you in clear clean sound with deep booming bass. I’m going from a 9.4 system that used 2 subwoofers and 4 surround speakers, it was loud but flat and never enveloped me in clear clean sound. The app makes adjustments easy and offers custom sound profiles. The included remote is easy to use. The mark of a good system is how it sounds from low volume to high, and this system maintains an excellent sound profile throughout the volume levels. Had zero problems with rear speakers dropping out, syncing speakers to the soundbar is easy. If you want true theater sound..buy this.

The media could not be loaded. I’m coming from a 2.1.0 LG sound bar roughly 7 years old, I added a 5.2.0 book shelf to the rear to act as rear speakers s couple years ago and it worked flawlessly. So technically, it was a 7.3.0 set up, and it did the job for years, but lately I’ve been wanting to add some more immersion to my TV/ movie time with my lady. But also, didn’t want to spend $1500 - $4000, just to see if we’d like the extra boom and surround sound like other Dolby atmos surround sound systems. I’ve seen a few videos about this brand, I was already convinced to purchase after viewing the review videos on YouTube (specific video YT: B the Installer), luckily for me this was on sale for Prime day so it was a no brainer for me! To start, the set up was a breeze, rear speakers connected almost instantly for me with a solid white light, the cable is a decent length so you can stretch it pretty far, the only difficulty is just making a sure the rear speakers are leveled to each other, where you want them and an ideal location for the massive 10” subwoofer. The bass rumbles so good it shakes and vibrates our bed and walls lol, it all really makes a difference in specific locations depending on the configuration and acoustics of your room. Note in the attached video I have a an additional set of rear speakers that are 5.2.0 working in harmony with the ULTIMEA rear speakers, I must say the ULTIMEA rear speakers with the top firing speakers really changed how my rear bookshelf speakers sounded in a very positive manner, the ULTIMEA Skywave X70 all around added a unique immersion you only get to experience in an IMAX theatre. So I’d say with my rear bookshelf speaker it’s now a 12.3.4 setup with complete 360 surround sound. The volume gets pretty loud(see the attached video), it was only at a 12 volume (bass level set to +3 upfiring speakers set to +1 surround set to +3 for the attached video). The functionality of the system is very user friendly it would be a difficult task to make this even remotely difficult to use. The best part is the price of the system, even when it’s not on sale for $999 this would be a great entry level into Dolby atmos scene or a True 360 surround sound home experience. Only reason for a 4 star instead of 5 my left front speaker had a small dent on top of the topfiring speaker screen, I was really shocked considering how well the packing was, there was no wiggle room for anything in there it was top notch, so I’m assuming they didn’t such a good job at quality control and sent this one to me with a slight dent on the top front top firing speakers for the main bar, it’s not noticeable only because it facing upwards rather directly facing me, other than extremely satisfied with my purchase! 10/10 recommend build quality feels like top notch quality materials, certainly didn’t feel cheap.

The system was very easy to hook up , loved the wireless connections for surround speakers . Dialogue was ok out of the box but needed tweaking through the app downloaded to a phone , the equalizer function on the phone helped with my room acoustics. The up firing speakers sounded way to shrill at higher settings which partially drowned out dialogue from the front firing speakers . The surround speakers were just ok , again too shrill at higher volume levels , very disappointed with the surrounds , no bass at all , just mid to high frequencies. The subwoofer was adequate even at higher levels , the subwoofer has a boominess at all listening levels , no tight punchy bass , but adequate for the price point and watching movies . In my opinion the weak links are the subwoofer and cheap surrounds . Ultimea needs to work on these low points .
