Design and Aesthetics
The design of both soundbars caters to different preferences, with the LG S70TY offering a more stylish look. The LG S70TY features a sleek crest design, making it not only functional but also a visually appealing addition to your entertainment setup. Its compact size allows it to fit neatly beneath an LG QNED TV, while its metal grill helps keep dust out. In contrast, the Samsung B-Series Soundbar HW B400F has a simpler design that's practical but less distinctive. Both products are designed to be seen and heard, but the LG’s aesthetic stands out, especially for users looking to complement their LG QNED TVs.
Sound Quality
In terms of sound quality, the LG S70TY excels with its Dolby Atmos and DTS technologies, providing an immersive 3D spatial sound experience. This soundbar features 3.1.1 channels and a wireless subwoofer, which enhances clarity and depth, particularly in dialogue. The Samsung B-Series Soundbar HW B400F, while offering balanced audio with a built-in subwoofer, is less advanced in terms of channels, providing only 2.0 channels. The LG's ability to project sound in a more spatial manner, particularly with its up-firing center channel, makes it a preferable choice for audiophiles and home theater enthusiasts.
Features and Technology
The LG S70TY is packed with advanced features, including WOW Orchestra, which synchronizes audio from the LG TV and soundbar for a seamless listening experience. It also allows users to control both devices with a single remote, adding convenience. On the other hand, the Samsung B-Series Soundbar HW B400F offers a more straightforward approach with features like voice enhancement mode and surround sound expansion. While the Samsung soundbar is easier to set up and use, the LG soundbar's advanced features cater to users desiring a more integrated and immersive experience.
Compatibility
When it comes to compatibility, the LG S70TY is specifically designed for LG QNED TVs, ensuring a perfect match in both aesthetics and functionality. It is compatible with the LG QNED Synergy Bracket, scheduled for release in August 2024, enhancing its integration with LG televisions. The Samsung B-Series Soundbar HW B400F, however, is designed to connect seamlessly with Samsung TVs, making it a great option for users within that ecosystem. While both soundbars offer easy connectivity, the LG’s specialized design gives it an edge for LG TV owners.
Price Comparison
The LG S70TY is priced at $346.99, which is significantly higher than the Samsung B-Series Soundbar HW B400F, priced at $99.99. This makes the Samsung model about 71% cheaper than the LG soundbar. However, the price difference reflects the varying features and sound quality each product offers. The LG soundbar, with its advanced technology and multiple channels, justifies its higher price for those seeking a high-end audio experience, while the Samsung model serves as a budget-friendly option for everyday use.
Sales Performance
In terms of sales rank, the Samsung B-Series Soundbar HW B400F is a bestseller, with a rank of 268, compared to the LG S70TY, which is ranked at 4,075. This difference suggests that the Samsung soundbar is more popular among consumers, likely due to its lower price point and ease of use. The LG model, while offering superior sound and features, may appeal to a more niche market willing to invest in a premium audio experience.
User Experience
The user experience differs significantly between the two soundbars. The LG S70TY provides a more sophisticated experience with its WOW Orchestra feature and comprehensive control through a single remote. Users can enjoy crystal-clear conversations and immersive sound effects, especially when paired with an LG TV. On the other hand, the Samsung B-Series Soundbar HW B400F focuses on simplicity and ease of use, allowing users to control sound functions with their Samsung TV remote. This makes it an attractive choice for those who prioritize straightforward setup and operation.
Which should you buy?
Ultimately, the choice between the LG S70TY and the Samsung B-Series Soundbar HW B400F depends on your specific needs and budget. If you're looking for a premium sound experience with advanced features and you own an LG QNED TV, the LG S70TY is worth the investment at $346.99. However, if you prefer a more budget-friendly option that still offers decent sound quality and ease of use, the Samsung B-Series Soundbar HW B400F at $99.99 is a solid choice. Each soundbar serves different user preferences, making your choice heavily reliant on your existing setup and audio needs.
