Cool music as released 1080P mobile projection R4/R4S starting price 2799 yuan
On December 1st, Cool Music unveiled two new smart mobile projectors, the R4 and R4S, on their official platform. Both models boast a 1080P resolution and high brightness, matching the performance of top-tier projectors in the same category. In terms of pricing, these devices are positioned as highly competitive options, claiming to offer 1080P quality at a price typically associated with 720P models. But how exactly does Cool Music price the R4 and R4S? According to the official announcement, the R4 is priced at 3,299 yuan, while the R4S comes in at 3,799 yuan. However, during the launch event, customers could enjoy an introductory discount, bringing the prices down to 2,799 yuan for the R4 and 3,399 yuan for the R4S.
Visually, the R4 and R4S share the same design, but differ in color options. The R4 features a bright silver finish, while the R4S is available in a sleek black variant. Both models feature a cuboid body with smooth curved edges, giving them a refined and modern look. The panels are made from full-metal material, enhancing the overall aesthetic appeal. One of the standout features is the built-in handle, making it easy to carry around. Notably, the R4S comes with a leather handle, adding a touch of premium comfort.
The R4 and R4S both support a 1920x1080p resolution, ensuring sharp and clear visuals. What sets them apart is their impressive brightness levels—R4 delivers 800 ANSI lumens, while the R4S offers 880 ANSI lumens, allowing users to enjoy high-quality projections even in well-lit environments.
In terms of light source technology, both models use a groundbreaking 4-LED system with RGGB color channels. This innovative design allows for higher current LED usage, resulting in up to 70% better brightness compared to similar products. To further enhance optical performance, Cool Music collaborated with optical expert Ma Yongzhen to develop a 7-piece all-glass telecentric HD lens combined with a precision-milled metal lens barrel. This advanced optical setup improves clarity and stability, delivering superior image quality.
For smart hardware, the R4 and R4S are powered by the latest Mstar 64-bit processor, offering a maximum configuration of 3GB RAM + 16GB storage. This ensures smooth performance for both system operations and video playback.
To elevate the audio experience, Cool Music partnered with AR (Acoustic Research) to create a dual-channel split-band HIFI stereo system. The unique speaker arrangement delivers true stereo sound and immersive surround effects, making every movie or music session more enjoyable.
Another notable feature is the lens cover design. The phrase “film to the right, music to the left†perfectly describes the sliding mechanism. Sliding the cover to the right activates the movie mode, while sliding it to the left switches to audio mode. It also allows users to turn off the light system, making it both functional and user-friendly.
In terms of content, the R4 and R4S are equally powerful. They connect to the GITV broadcast control platform, offering access to over 120,000 TV episodes, 600 million movies, 80 million anime episodes, and 1,200 variety shows. This vast library caters to a wide range of viewing preferences.
For user convenience, the projectors include features like automatic trapezoidal correction, wireless screen mirroring, 3D display, and electric/auto focus. These enhancements make daily use more intuitive and efficient.
Both the R4 and R4S are now available on Tmall and JD.com. If you're interested in experiencing high-quality mobile projection, be sure to check them out!
