The LG S40TR and TCL S55H are both compelling soundbar options that aim to enhance your home audio experience. The LG S40TR, priced at $196.99, features a 4.1 channel setup with rear surround speakers and a wireless subwoofer, while the TCL S55H comes in at a more budget-friendly $129.99 and offers a 2.1 channel system with a powerful wireless subwoofer. The LG model has a bestseller rank of 1825, while the TCL sits slightly lower at 1884, showcasing a competitive landscape in the soundbar market.
Design and Build Quality
In terms of design, both soundbars are crafted to blend seamlessly with modern home aesthetics. The LG S40TR boasts a sleek crest design that not only looks stylish but is also functional, featuring a metal grill that protects against dust and debris. The TCL S55H, on the other hand, is designed with a low-profile structure that fits neatly under your TV, creating a clean and refined setup. Its size dimensions are intentionally designed to avoid bulkiness, making it visually appealing without sacrificing performance. Both models exhibit premium feel and quality, although the LG's design emphasizes both aesthetics and protective features.
Audio Performance
Audio performance is a crucial factor for any soundbar, and both models deliver in their own ways. The LG S40TR provides an immersive listening experience with its 4.1 channel setup and Dolby Audio technology, delivering detailed sound for movies and music. The inclusion of rear surround speakers enhances its capability to create a spatial audio environment. The TCL S55H, with its Dolby Atmos and DTS Virtual:X support, also aims for an immersive experience, focusing on delivering deep bass through its 220W subwoofer. While the LG excels in surround sound capabilities, the TCL’s powerful output is perfect for filling small-to-medium rooms with rich audio.
Connectivity Options
When it comes to connectivity, both soundbars offer a range of options for easy integration with your home entertainment systems. The LG S40TR allows for seamless control with its WOW Interface, letting users manage both the soundbar and LG TVs with a single remote. This feature enhances user convenience. The TCL S55H is also versatile, featuring HDMI eARC/ARC, optical, Bluetooth, and AUX connections, making it compatible with various devices. While both soundbars provide solid connectivity, the LG's ability to unify control with its interface gives it a slight edge in user experience.
Setup and Usability
Setting up a soundbar should be straightforward, and both the LG S40TR and TCL S55H deliver on this front. The LG model’s wireless rear speakers help eliminate clutter, making installation easier without needing additional receivers. Additionally, its user-friendly WOW Interface simplifies the adjustment of audio settings. Conversely, the TCL S55H touts a simple plug-and-play setup, complemented by intuitive remote control. It even includes a bonus wall-mount kit for those looking to save space. Both soundbars are designed for ease of use, but the TCL’s additional setup accessories may appeal to users needing flexible installation options.
Price and Value
Pricing is a significant consideration, and there's a notable difference between the two soundbars. The LG S40TR is available for $196.99, while the TCL S55H is priced at $129.99, making the TCL about 17% cheaper. This price difference could be a crucial factor for budget-conscious consumers. Despite the lower price, the TCL does not compromise on audio quality, offering features like a powerful subwoofer and Dolby Atmos compatibility. The LG S40TR, while more expensive, provides enhanced surround sound capabilities, which might justify the higher cost for audiophiles.
Brand Reputation and Support
Brand reputation can often influence purchasing decisions, and both LG and TCL have established themselves in the electronics market. LG is well-regarded for its audio and visual technology, and the S40TR reflects that with its advanced features and strong build quality. TCL, known for its value-driven products, delivers reliable performance and customer support, making the S55H a solid choice for those seeking quality without breaking the bank. While both brands offer good support, LG’s long-standing reputation in audio technology may give it an edge for those prioritizing brand trust.
Which should you buy?
Choosing between the LG S40TR and the TCL S55H ultimately depends on your specific needs and budget. If you are looking for a more immersive audio experience with surround sound capabilities and don’t mind spending a bit more, the LG S40TR is a fantastic option.

Both soundbars have their strengths, making your choice contingent on what aspects of sound and usability matter most to you.
