Design and Aesthetics

The LG S70TY boasts a sleek design that perfectly matches LG's QNED series TVs, making it an aesthetically pleasing addition to your home entertainment setup. In contrast, the Samsung Q990D features a more robust design, emphasizing its premium build quality and advanced features.

The LG S70TY's compact size allows it to fit neatly beneath compatible LG TVs or be mounted on the wall, while its metal grill prevents dust accumulation. The Samsung Q990D, with its 11.1.4 channel setup, is designed to stand out with multiple front-facing and up-firing speakers, providing a more immersive audio experience. Each soundbar serves its purpose well, but the choice may come down to personal preference in style—sleek minimalism versus a more pronounced presence.

Audio Performance

When it comes to audio performance, the Samsung Q990D takes the lead with its 11.1.4 channel True Dolby Atmos sound. This soundbar features 11 front-facing speakers and 4 up-firing channels, delivering an immersive audio experience that fills the room. In contrast, the LG S70TY offers a 3.1.1 channel configuration, which is impressive but less expansive than the Samsung’s setup.

While the LG S70TY provides excellent clarity and attention-grabbing bass, particularly suited for dialogue due to its up-firing center channel, it may not match the expansive surround sound experience of the Samsung Q990D. Thus, for those seeking a cinematic home theater experience, the Samsung soundbar is likely the preferred choice.

Connectivity Options

Connectivity is a strong point for both soundbars, but they approach it differently. The Samsung Q990D features wireless Dolby Atmos and includes a rear speaker kit, providing a tangle-free setup that enhances the immersive audio experience. The LG S70TY, while also wireless, primarily focuses on Bluetooth connectivity and is designed to integrate seamlessly with LG TVs using one remote.

The Samsung Q990D offers additional smart integration features, including built-in Alexa and compatibility with services like Chromecast and AirPlay 2, making it a more versatile option for those who prioritize smart home connectivity. This gives the Samsung soundbar a slight edge for users looking for advanced integration with their existing smart devices.

Pricing

In terms of pricing, the LG S70TY is significantly more affordable at $346.99, making it about 64% cheaper than the Samsung Q990D, which is priced at $969.95. This price difference of roughly $622.96 could be a decisive factor for budget-conscious consumers looking for a quality soundbar.

While the LG soundbar provides excellent value for its price, the Samsung soundbar's higher cost corresponds with its advanced features and superior audio performance. Consumers should weigh these factors against their budget and audio needs when making a decision.

Smart Features

Smart features are another area where the Samsung Q990D stands out. It includes advanced functionalities like Q-Symphony, which allows it to work in tandem with a Samsung TV for an optimized audio experience. Additionally, it features Adaptive Sound, which intelligently adjusts audio settings based on the content being played.

The LG S70TY offers its own perks with the WOW Interface, allowing users to control both the soundbar and LG TV with a single remote. However, it lacks the extensive smart capabilities of the Samsung soundbar. For users looking for a more integrated smart home experience, the Samsung Q990D is the more appealing option.

User Experience

User experience can greatly affect satisfaction with a soundbar. The LG S70TY ranks at 4075 on bestseller lists, indicating its popularity among users who appreciate its straightforward setup and effective performance. Its design is user-friendly, making it an excellent choice for those who prioritize ease of use.

In comparison, the Samsung Q990D, with a sales rank of 2912, suggests a strong appeal as well. Users may find its extensive features and immersive audio experience particularly rewarding, especially in larger spaces. However, the complexity of features may be overwhelming for some users. Both soundbars cater to different segments of the market, appealing to both ease of use and advanced functionality.

Warranty and Support

Warranty and support can influence buyer confidence in a product. While specific warranty details are not provided in the data, reputable brands like LG and Samsung typically offer substantial customer support and service options. This is essential for troubleshooting and ensuring longevity of the product.

The overall market reputation of Samsung for its premium products might lend an advantage in perceived reliability, while LG's strong focus on compatibility with its own TVs could assure users of seamless integration and support. Buyers should consider the importance of brand support when making their choice.

Which should you buy?

Choosing between the LG S70TY and the Samsung Q990D ultimately depends on your specific needs and budget. The LG S70TY offers a more budget-friendly option with solid performance, especially for those who own an LG QNED TV. It’s a great choice if you're looking for excellent sound quality without breaking the bank.

On the other hand, the Samsung Q990D provides superior audio performance and advanced smart features, making it ideal for audiophiles and users looking for an immersive home theater experience. If budget is less of a concern and you seek the latest audio technology, the Samsung soundbar is the way to go.
