Overview of Hisense AX3120Q and LG OLED evo C4 Series TV with Soundbar
The Hisense AX3120Q soundbar is significantly more affordable than the LG OLED evo C4 Series TV and matching soundbar, retailing at $279.99 compared to LG's $1,323.94. For buyers seeking a budget-friendly option without sacrificing audio quality, the Hisense model presents an attractive choice. In contrast, the LG offering combines cutting-edge TV technology with an advanced soundbar, appealing to those who prioritize high-end visual and audio experiences.
Audio Performance
The Hisense AX3120Q features a robust 3.1.2 audio channel setup that includes five front-firing and two up-firing speakers, delivering immersive sound through Dolby Atmos and DTS:X technology. This configuration is designed to create a three-dimensional sound experience, filling the room with dynamic audio. The built-in 6.5” wireless subwoofer enhances the bass, ensuring powerful sound without distortion.
On the other hand, the LG OLED evo C4 Series TV is paired with the 3.1.1 S70TY QNED soundbar, which also supports Dolby Atmos. While both systems offer immersive sound experiences, the Hisense soundbar boasts additional channels and a dedicated subwoofer, which may provide a richer audio experience for movie and music enthusiasts.
Visual Quality
In terms of visual performance, the LG OLED evo C4 Series TV stands out with its self-lit pixel technology, producing exceptional picture quality with over 8 million pixels. This technology allows for stunning color accuracy and deep contrasts, making it ideal for cinematic viewing. The Brightness Booster feature enhances the brightness and detail, ensuring a captivating viewing experience in various lighting conditions.
In contrast, the Hisense AX3120Q is strictly a soundbar without any video capabilities, which means it relies on a separate display for visual content. Therefore, those seeking a comprehensive audio-visual solution may find the LG model more appealing due to its exceptional display quality.
Design and Aesthetics
The Hisense AX3120Q sports a sleek black finish that fits well in most home environments. Its design is straightforward, prioritizing functionality over flair. It is designed to be easily mounted or placed beneath a TV, making it a versatile addition to any setup.
Conversely, the LG soundbar features a stylish crest design that not only enhances its aesthetic appeal but also serves a practical purpose by keeping dust and debris out. This combination of form and function makes the LG soundbar a visually striking option that complements the high-end look of the OLED TV.
Connectivity Options
When it comes to connectivity, the Hisense AX3120Q offers multiple options, including HDMI eARC, Bluetooth 5.3, and optical inputs, making it versatile for various devices. The Bluetooth feature allows for easy streaming of music and podcasts directly from mobile devices, enhancing its usability.
The LG OLED evo C4 Series TV also provides robust connectivity options, including compatibility with the LG QNED Synergy Bracket for wall mounting, making it easy to integrate into a home entertainment system. However, while both products offer Bluetooth connectivity, the Hisense model provides a broader range of input options, which may appeal to users with diverse entertainment setups.
Price Comparison
The Hisense AX3120Q is priced at $279.99, making it about 79% cheaper than the LG OLED evo C4 Series TV and soundbar combo, which retails for $1,323.94. This significant price difference makes the Hisense model an attractive option for budget-conscious consumers who want quality audio without breaking the bank.
While the LG model justifies its higher price with advanced display technology and superior build quality, the Hisense soundbar still delivers excellent audio performance at a fraction of the cost, catering to those who may not require the latest in visual technology.
Best Seller Status
The Hisense AX3120Q holds a sales rank of 4,836, indicating that it is a popular choice among consumers in the soundbar category. Its combination of features and competitive pricing likely contributes to this ranking, suggesting a strong value proposition for buyers.
In comparison, the LG OLED evo C4 Series TV has a sales rank of 6,447, which, while respectable, shows it may not be as widely purchased as the Hisense model. This difference could indicate that consumers are currently leaning towards more affordable audio solutions rather than high-end video products.
User Experience and Setup
The Hisense AX3120Q is designed for ease of setup, featuring a plug-and-play configuration that allows users to quickly elevate their TV's audio performance. Its remote control includes quick touch EQ modes that let users switch between different sound profiles tailored for music, movies, news, and more.
The LG OLED evo C4 Series TV also offers an intuitive user experience, particularly with its AI processor that enhances both audio and video settings automatically. However, users looking for a straightforward audio upgrade might find the Hisense option more appealing due to its simplified setup and dedicated audio focus.
Which should you buy?
Choosing between the Hisense AX3120Q and the LG OLED evo C4 Series TV with soundbar ultimately depends on your needs and budget. If you're looking for an exceptional audio experience at a lower price point, the Hisense model is an excellent choice with its immersive sound capabilities and ease of use. However, if you prioritize high-quality visuals along with audio and are willing to invest more, the LG OLED evo C4 Series offers a premium experience that combines stunning display technology with a solid soundbar.
