With the rapid growth of the smart micro-projector market, we once again experience the power of technology. Now, it's possible to enjoy an immersive viewing experience from the comfort of your home. While the mainstream in the market still runs on 720P resolution, Cool LeTV has taken a bold step forward with its S3 smart projector, offering over 1,000 lumens of brightness that makes daytime projections crystal clear. Building on this success, Cool LeTV has now launched the next-generation R4 1080P smart projector, delivering significant upgrades in resolution, brightness, audio quality, and design.
What’s even more impressive is the price. The R4 is priced at around 3,000 yuan, making high-end 1080P projection accessible to a broader audience. How does it perform? Let’s dive in.
Cool Music, as the brand, is no stranger to the smart micro-projector scene. Known for its "price-busting" strategy, it has built a loyal fanbase by offering high-quality products at affordable prices. The R4 continues this tradition, bringing 1080P HD projection into a price range that used to be reserved for premium models costing 5,000–6,000 yuan.
The packaging of the R4 follows a sleek black box design with the R4 logo prominently displayed. Inside, the projector is well-protected with sponge compartments, ensuring safe delivery. It comes with a power adapter, remote control, user manual, and warranty card. Notably, the power adapter uses a 15V-6.6A specification, which is not compatible with previous models like the S3.
Visually, the R4 is a significant departure from its predecessor, the S3. It features a three-dimensional cube design with all-metal elements, giving it a modern and dynamic look. The main color scheme is black and white, with dynamic red accents that add a stylish touch. The metal lens cover and leather strap (upgraded in the R4S model) are details that elevate the overall aesthetic.
The R4 also boasts a unique speaker system. Its left-right separated design enhances sound quality, and the HIFI logo on the speaker net adds a premium feel. This is not just a projector—it's a two-channel HIFI audio system, delivering cinema-like stereo sound.
On the front, the R4 features a slide-protected HD lens. The lens consists of seven glass elements and a precision-milled metal barrel, ensuring sharp and clear images. The projector supports 1080P resolution and has been optimized for full HD performance, making it ideal for both movies and games.
The R4 also includes a WiFi speaker mode, allowing users to switch between projection and audio playback with ease. A physical button interface has been reintroduced, offering an alternative to the remote control for those who prefer direct access. The LED status bar on top provides real-time feedback on the device’s operation.
The handle on top allows for easy portability, while the adjustable feet on the bottom support trapezoidal correction, helping to fit the image to different environments. The interface on the back is well-designed, featuring multiple ports including HDMI 2.0, USB, AV, and audio outputs.
Powered by a 64-bit Mstar chip, 1GB RAM, and 16GB storage, the R4 delivers smooth performance and fast boot times. The Cool OS system is intuitive and user-friendly, designed specifically for projectors. It offers four main modules: films, music, office, and games, with a simple and elegant UI.
In terms of content, the R4 partners with iQIYI and Galaxy GITV, providing access to a vast library of videos and HIFI music. Users can also download third-party apps via USB, making the R4 a versatile smart device.
Support for 3D playback is another highlight, requiring active shutter glasses for optimal viewing. The R4 also supports paperless office functions, allowing users to view PPTs, Word docs, Excel files, and PDFs directly on the projector.
Overall, the Cool LeTV R4 is a game-changer. With its stunning design, powerful hardware, and competitive pricing, it sets a new standard in the smart micro-projector market. Whether you're watching movies, playing games, or working, the R4 delivers an exceptional experience that rivals much more expensive models.
