The bar measures 810 mm wide, and the subwoofer measures 195 x 320 x 195 mm. The LED display and touch keys make everyday control simple for the whole family.
Real-world feedback praises its Dolby Atmos immersion in films and games. Stated power reaches up to 220W total, so compare that figure carefully with other models.

- Deep bass that users often praise
- AI Sonic-Adaptation tunes audio to the room

Head to Head: Key Differences
Picking between these two soundbars comes down to your room and daily habits. Both models bring strong sound to a living room, but each one suits a different kind of viewer.
The JBL SB580 uses a 3.1 layout. The TCL S55H uses a 2.1 layout.
Layout changes how sound spreads across the room, so it helps to know what each one offers.
Think about your viewing habits first. If you watch news, talk shows, or crime dramas most nights, the JBL fits that routine well. If you mostly watch action films or play loud games, the TCL may feel more exciting.
Check your room size and layout. Bigger rooms often need more presence to feel full, so measure the space before you buy. Plan where the subwoofer will sit, since that spot changes how the bass feels.
Consider how you like to set things up. Some people enjoy adjusting settings by hand, while others want a simple setup they can forget. Think about which style suits you before you commit.
Know what the sources cannot tell you. Neither model has sourced cons from independent testing, and most feedback comes from users or promotional videos. Read recent tests, check the return policy, and compare how each bar sounds at home or in a store if possible.
Choose the JBL if clear voices matter most. Choose the TCL if you want bold, bass-heavy action and simple, hands-off tuning.
Which One Should You Buy
JBL SB580 wins this comparison overall. It offers a dedicated center channel, HDMI eARC, Wi-Fi streaming, and higher stated power.
These features give it the stronger spec sheet for TV and movie use.
The TCL S55H has real strengths. Its praised bass, Atmos immersion, and room auto-tuning stand out.
However, the sources do not prove these benefits as clearly as the JBL’s hardware features.
For most TV watchers, the JBL is the safer pick. Its hardware fits everyday viewing well.
Best for each buyer
- JBL SB580: Viewers who watch dialogue-heavy TV and movies, and anyone who needs HDMI eARC or Wi-Fi streaming rather than Bluetooth only.
- TCL S55H: Movie and gaming fans who want deep bass and immersive Atmos sound, and who have a room that benefits from automatic audio optimization.
