Pricing Comparison

The Bigme B7 Color eReader is priced at $319.97, while the Kobo Libra Colour is available for $285.99, making the Kobo approximately 17% cheaper. This price difference could be significant for budget-conscious readers looking for a reliable e-reader. The Bigme model is a bit more expensive due to its advanced features, such as 4G calling and larger storage options, which may appeal to a niche market willing to invest more for those capabilities.

Display Quality

The Bigme B7 boasts a 300PPI E-ink Kaleido 3 display, providing vivid colors and a paper-like reading experience. In contrast, the Kobo Libra Colour focuses on a full-color display that enhances book covers, comics, and illustrations without glare. While both e-readers offer color, the Bigme's higher pixel density suggests sharper text and images, which could be beneficial for extensive reading sessions. The choice here largely depends on whether you prioritize sharpness or the vibrant presentation of multimedia content.

Features and Functionality

The Bigme B7 Color eReader stands out with its Android operating system, which allows the installation of third-party apps. It also offers 4G calling capabilities and comes with a stylus, making it versatile for note-taking and document annotation. On the other hand, the Kobo Libra Colour emphasizes its compatibility with the Kobo Stylus 2 for annotations but lacks the full-fledged Android experience. If you need an e-reader that functions more like a tablet, the Bigme is the clear winner, while the Kobo is more traditional in its approach.

Storage and Capacity

When it comes to storage, the Bigme B7 offers a substantial 128GB internal memory, expandable up to 1TB via a micro SD card. This capacity allows users to store around 70,000 books, ideal for avid readers. In contrast, the Kobo Libra Colour provides 32GB of storage, sufficient for about 24,000 eBooks or 150 audiobooks. If storage capacity is a crucial factor for you, the Bigme's offering is significantly more robust, allowing for greater flexibility in managing your digital library.

Battery Life and Usage

Both devices promise impressive battery life, but the specific longevity in usage isn’t detailed in the specifications. The Bigme B7 allows for weeks of reading, which is typical for e-ink devices, while the Kobo Libra Colour also offers weeks of battery life. However, the Bigme's additional features, like the stylus and 4G connectivity, may impact battery performance during extensive usage. For those primarily interested in a straightforward reading experience, either device would suffice, but the Bigme may require more frequent charging depending on usage patterns.

Design and Ergonomics

The Kobo Libra Colour is ergonomically designed with page-turn buttons and customizable screen settings, catering to a comfortable reading experience. It also comes with an IPX8 waterproof rating, allowing it to be submerged in water for up to 60 minutes. The Bigme B7, while stylish, focuses on a larger screen and a more tablet-like design, which may not provide the same ease of one-handed use as the Kobo. If you prefer reading in various environments, the Kobo's waterproof feature is a significant advantage.

Additional Features

The Bigme B7 includes a powerful Octa-Core processor and a 5-megapixel rear camera, enhancing its functionality beyond just reading. Its ability to support various multimedia tasks makes it a versatile option. The Kobo Libra Colour, although lacking in processing power, excels in providing a distraction-free reading experience, with no notifications and a focus on reading. Depending on your needs—whether you desire a comprehensive device for various tasks or a dedicated e-reader—the choice becomes clearer.

Which should you buy?

Ultimately, the decision between the Bigme B7 Color eReader and the Kobo Libra Colour hinges on your individual needs. If you require a feature-rich device capable of multitasking, with significant storage and advanced capabilities, the Bigme is worth the investment at $319.97. However, if you're looking for a more budget-friendly option focused primarily on reading, the Kobo Libra Colour at $285.99 offers great value with its ergonomic design and waterproof features. Choose based on whether you prioritize advanced functionalities or a simplified reading experience.
