On September 8, iReader launched its new portable flagship reader, the Tango2S E Ink reader, now on sale across all channels. Centered on an extremely light and comfortable in-hand feel, the new device debuts the world's first 5.84-inch 300ppi Carta1300 E Ink screen together with a soft-light frontlit display, delivering all-round upgrades in screen quality, performance, and slim portability for a pure, immersive reading experience on the go.

Lightweight and Easy to Hold: A Compact Body with No Hand Fatigue

The Tango2S strikes a refined balance between size and weight: a 5.84-inch screen in a body weighing just 147 g, further slimmed down from its predecessor. The compact body is easy to control with one hand and slips into a pocket without pressure, making it perfect for fragmented reading scenarios such as commuting and travel, and comfortable even during long reading sessions. The back cover uses a new eco-friendly silicone leather material that combines a skin-friendly feel, environmental responsibility, and durability, further improving the grip quality.

Clear Reading Experience: World's First 5.84-inch 300ppi Carta1300 Screen with Soft-Light Frontlight

The Tango2S is equipped with the world's first 5.84-inch 300ppi Carta1300 E Ink screen, offering 27% faster screen response for fluid page turns, 20% higher contrast, and inky-black, razor-sharp text with rich, layered images. The fully upgraded soft-light frontlight is optimized across the entire optical chain through three core technologies: newly customized soft-light LEDs paired with a HOST light-scattering polymer light guide plate improve frontlight uniformity; micron-level bonding technology with a new optical bonding medium optimizes light transmission for clear, transparent text; and nano-etched tempered glass reduces ambient reflections and glare, keeping the screen pure and gentle in any lighting condition, day or night, for a paper-like reading comfort.

Stable and Smooth: Yunyan Architecture with High-Performance Fast Refresh

The Tango2S features iReader's self-developed Yunyan protective architecture, with a built-in high-toughness, high-strength frame and an integrated support structure that distributes stress evenly for stronger impact resistance, handling everyday bumps and accidental drops. The front is covered with high-strength bend-resistant tempered glass to prevent screen deformation under pressure. A shielding chamber inside the body blocks static electricity and electromagnetic interference, keeping touch control and signal stable even in complex environments.

The self-developed fast-refresh technology delivers a dynamic refresh rate of up to 50 frames per second, greatly reducing ghosting with flicker kept nearly at zero. Paired with the upgraded iClean 2.0, ghosting removal in dark and night modes improves by 90%. With an 8-core CPU plus an independent GPU and a 4GB+64GB configuration, CPU performance is 200% higher than 4-core models, providing ample computing power for multitasking and image-heavy content loading. The upgraded 256-level grayscale 3.0 renders finer tonal transitions in comics, while the custom water-ripple page-turn effect delivers realistic, fluid page turns with excellent ghosting control even in dark mode.

Ergonomic Design: Upgraded Smart Buttons for Effortless Control

The Tango2S adopts an ergonomic dual smart physical button design, with recessed buttons on both sides that fit the natural curve of the palm and work for either left- or right-handed grip. A new customizable shortcut button supports one-tap jumps to any page position, allowing page turns and function navigation to be completed with one hand, greatly simplifying the E Ink operation flow and reducing interruptions for a more immersive reading experience.

Massive Storage Expansion: Supports Memory Cards up to 2TB

A new memory card expansion feature breaks through the native storage limit, supporting memory cards up to 2TB. Tens of thousands of e-books, high-resolution comics, and study documents can be stored offline without repeated deleting and backing up, so reading and learning resources are always at hand whenever the device is opened.

Overall, the iReader Tango2S reshapes the standard for small-size E Ink readers with its ultra-slim portable positioning, high-resolution and gentle flagship screen, and smooth, stable system experience, meeting the core need for high-quality reading on the go. iReader will continue to deepen its innovation in E Ink hardware and software, polishing more high-quality reader products tailored to the real usage scenarios of reading enthusiasts.
