Review: For the Money - I wasn’t sure what to expect at this price point, but the TCL S45H has really surprised me with its power and sound quality. For a compact 2.0 channel bar, it delivers a clear, rich sound that easily fills the room. The dialogue is crisp, the bass has more punch than I expected without being muddy, and the overall balance makes both movies and music enjoyable. The inclusion of Dolby Atmos and DTS Virtual:X is a huge plus. Even without extra speakers, the virtual surround creates a much more immersive experience than I thought a budget-friendly soundbar could achieve. It really elevates TV shows, movies, and even gaming. Setup was simple—just plug it in, connect via HDMI or Bluetooth, and it was ready to go. The Bluetooth streaming works seamlessly for music, and the auto room calibration feature actually makes a noticeable difference in tailoring the sound to your space. Overall, this soundbar is an incredible value. It looks sleek, performs far above its price range, and is perfect for anyone who wants to dramatically improve their TV audio without breaking the bank.
Review: Amazing sound - Whoa. I just got this soundbar today for my new TCL QM6K tv and this thing is loud. The sound quality is amazing. I have it at 28 and it’s crazy loud. I am using a 2.1 hdmi cable in the eArc slot and the Dolby atmos sound is great. I hope it last a while because this what i needed for this tv. The control is little and nice. It’s easy to setup. It’s pretty long so make sure you have space for it.

### ⭐⭐⭐⭐ Great entry level sound bar
*by K***A on January 1, 2025*

I have been hearing abound sound bars and how good they can be for a while now. I finally decided to get this one and try it out. I have a TCL TV so I wanted to stick with the same brand of soundbar. The install went easy enough, I used the HDMI (eARC) port on my TV and it found it instantly. The TV muted the internal speakers and now only outputs through the sound bar. I don't have my TV on the wall yet, it's still on a stand. this soundbar barely fits under the TV and even blocks the receiver. I had to add a few furniture pads under the TV's feet to give me enough clearance so the soundbar can fit under it and I can use the remote to control the TV. The sound quality sounded not good at 1st. I heard little pops kind of like static. I tried reseeding the HDMI cable and even tried another cable and it did the same thing. I installed the TCL app, (and setup an account at the TCL site). The app found the soundbar and did a calibration, after that it sounded much better. since plugging in the sound bar, the TV always turns on with the sound on. When I was using the internal speakers it would remember the mute between restarts. There is only a single light bar at the top of the soundbar to tell you volume levels and it changes color to indicate what input it's using. There is no way to tell if certain features are on or off unless you look in the app, this is mainly for surround enhance or dialog enhance. Also changing the profile (music, movie, sports) can be done with the remote, but it's best to do through the app so you know for sure which mode you are on. Overall not a bad entry into the soundbar world. It's affordable, and it works. I no longer need to put my TV volume to 35+ to hear what I am watching I can leave the soundbar down to 10-15 and hear it just fine.
