Ikko, a Shenzhen company known for earbuds and audio accessories, has released the MindOne Pro — a 4-inch square-screened Android phone priced at $499, currently discounted to $429 on its website. The Verge's Allison Johnson published a hands-on review after first seeing the device at CES in January 2026.

The hardware is genuinely different from what you see on store shelves. The MindOne Pro pairs a 4-inch OLED screen with a slightly rectangular body, and its 50-megapixel camera sits on a flip mechanism that rotates upward to work as either a rear-facing or front-facing camera — and when partially raised, as a physical kickstand. An optional keyboard accessory, similar in concept to magnetic keyboards that snap onto conventional phones, adds physical keys and includes a headphone jack. Ikko's website advertises "Free Global Internet Built-In," and the company confirms it ships worldwide.

Where the Hardware Hits Reality

The square display is at the center of most practical problems. Smartphones and websites are designed around tall, narrow screens. Videos are shot vertically. An onscreen keyboard alone eats up more than half the visible space. Ikko has included quick-settings toggles that let users switch the display to a taller aspect ratio with black bars on the sides — essentially fitting a rectangular shape onto the square panel — and to lower screen resolution. These are workarounds, not fixes.

Johnson's review flags two other hardware issues. The device ran noticeably warm during initial setup — warm enough to mention explicitly. Battery life was similarly tight: the device lost roughly 30 percent charge in about 90 minutes of moderate Wi-Fi browsing starting from the mid-90s. If that rate holds over a full day, you would struggle to reach evening on a single charge.

Camera performance added another concern. Photos taken in dim indoor light came out with a greenish tint — a color-processing issue that software updates can usually fix, but should not be present at launch on a $499 phone.

What This Device Actually Is

Ikko is not a company with years of smartphone experience. Audio-accessory makers who pivot to phones have a thin track record. Building a phone requires engineering and supply-chain expertise very different from making earbuds or audio adapters. Forbes reviewer Ben Sin called the MindOne Pro a "fun, useful second phone" in his May 2026 review — a description that quietly admits it is not meant to replace your main device.

That framing appears accurate. The compact phone market is genuinely starved for options: Sony's Xperia 5 series sits at the premium end, and below that, choices are scarce. A 4-inch device with an optional keyboard, global shipping, and a sub-$500 price point will attract a specific audience — power users who want a pocketable device for travel, developers who need terminal access on the go, or people simply tired of standard phone slabs.

The square shape is the boldest design choice here, and it cuts both ways. It is the device's clearest differentiator and also its biggest source of software headaches. The aspect-ratio toggle shows Ikko understands the problem; what remains to be seen is whether apps and content platforms will ever design natively around a square instead of fighting it.

The thermal and battery numbers come from a single hands-on session and may not reflect final software or extended daily use. Anyone seriously considering this device should test the keyboard accessory and aspect-ratio workarounds in person before buying — whether it can serve as your daily phone depends heavily on how your specific work and habits fit its constraints.

The MindOne Pro costs $499 globally, with worldwide shipping available.
