Design and Aesthetics

The LG S70TY 3.1.1-Channel QNED TV Matching Soundbar is designed to complement LG QNED TVs with its sleek profile and modern crest design. In contrast, the TCL S55H 2.1 Sound Bar offers a low-profile design that fits neatly under any smart TV. The LG soundbar not only looks stylish but also features a metal grill to keep dust out, enhancing its longevity. While both soundbars are visually appealing, the LG’s design aims for a perfect match with specific LG TVs, which might be less versatile for other brands.

Audio Performance

Audio performance is a significant differentiator between the two soundbars. The LG S70TY features Dolby Atmos and DTS technologies that deliver immersive 3D spatial sound, making it ideal for a home theater experience. It also includes an up-firing center channel that enhances dialogue clarity. On the other hand, the TCL S55H also incorporates Dolby Atmos and DTS Virtual:X, providing a cinematic audio experience with a wireless subwoofer that produces deep bass. However, the LG soundbar’s multi-channel setup (3.1.1) offers a more complex audio profile compared to the TCL's simpler 2.1 configuration.

Power and Output

The LG S70TY has a more robust audio setup with a multi-channel configuration that offers enhanced soundstage capabilities. However, the TCL S55H boasts a total output of 220W, which provides powerful room-filling audio, making it suitable for various room sizes. While the LG S70TY’s power output isn’t specified, it is designed to deliver immersive audio that may be particularly effective when paired with compatible LG TVs. The TCL’s higher wattage can be appealing for those who prioritize loud and impactful audio in smaller spaces.

Compatibility and Connectivity

When it comes to compatibility, the LG S70TY is specifically recommended for use with LG QNED TVs and includes features that allow for seamless integration, such as the WOW Interface for controlling both the soundbar and TV with one remote. The TCL S55H, meanwhile, is designed to work with any smart TV and offers multiple connectivity options including HDMI eARC/ARC, optical, Bluetooth, and AUX. This versatility makes the TCL soundbar a more flexible choice for users with varied home entertainment setups.

Price Point

In terms of pricing, the LG S70TY is currently available for $346.99, while the TCL S55H is priced at $129.99. This means the TCL soundbar is about 63% cheaper than the LG model, making it a more budget-friendly option for those looking to enhance their audio experience without breaking the bank. Despite the price difference, both soundbars offer significant audio enhancements, but the LG may justify its higher price with its advanced features and design tailored for LG TVs.

Customer Reception

The LG S70TY has a sales rank of 4,075, indicating a respectable position in the market, while the TCL S55H ranks even higher at 1,884. This suggests that the TCL soundbar is currently more popular among consumers, likely due to its lower price point and solid performance. Customer feedback often highlights the TCL’s ease of setup and sound quality, while the LG product is praised for its premium design and integration features.

Features and Usability

The LG S70TY includes standout features such as WOW Orchestra, which harmonizes audio from the soundbar and TV for an enriched listening experience. It also supports wireless rear speakers, enhancing the surround sound experience. The TCL S55H features AI Sonic auto room calibration, which adjusts audio to suit the room layout, ensuring balanced sound without complicated setups. While both soundbars offer unique features aimed at improving usability, the LG's integration with its TV ecosystem is particularly noteworthy for LG users.

Which should you buy?

In deciding between the LG S70TY and the TCL S55H, your choice ultimately depends on your needs and setup. If you own an LG QNED TV and are willing to invest more for enhanced audio performance and design, the LG S70TY is a great choice. However, if you’re looking for affordability and versatility, the TCL S55H offers excellent sound quality at a significantly lower price, making it suitable for a broader range of setups. Each soundbar has its strengths, so consider your specific requirements before making a decision.
