Overview of the eReaders
The Bigme B7 Color eReader retails for $319.97, while the Kobo Libra Colour is priced at $229.99, making the Kobo about 28% cheaper. Both devices feature a 7-inch color E Ink display, but they cater to different user needs and preferences. The Bigme B7 Color focuses on a more versatile digital experience with features like 4G calling and a higher storage capacity, whereas the Kobo Libra Colour emphasizes a streamlined reading experience with its waterproof design and compatibility with Kobo's ecosystem.
Display Quality
The Bigme B7 Color boasts a 300PPI E Ink Kaleido 3 display, which provides clear text and vivid images, ensuring a comfortable reading experience. This display is designed to minimize eye strain, making it suitable for extended reading sessions. On the other hand, the Kobo Libra Colour also features a 7-inch E Ink Kaleido 3 display but is specifically designed to be glare-free in sunlight. Both displays excel in their own right, but the Bigme's higher resolution may appeal more to users who prioritize image quality in their reading materials.
Performance and Operating System
With an advanced octa-core processor running at 2.3GHz, the Bigme B7 Color offers smooth performance for both reading and multitasking. It comes equipped with 8GB of RAM and 128GB of internal storage, allowing users to store approximately 70,000 books. In contrast, the Kobo Libra Colour has 32GB of storage, which is sufficient for carrying up to 24,000 eBooks or 150 audiobooks. While the Bigme provides more storage and a more powerful CPU, the Kobo's performance is optimized for a seamless reading experience.
Connectivity Options
The Bigme B7 Color supports both 2.4G and 5G Wi-Fi connections, as well as Bluetooth. It also includes 4G calling support, which allows users to stay connected even when away from Wi-Fi. This feature is particularly beneficial for those who want to use their eReader for communication. In comparison, the Kobo Libra Colour does not offer cellular connectivity but allows users to connect to Wi-Fi for downloading books and audiobooks. For those who prioritize connectivity, the Bigme B7 Color clearly stands out.
Battery Life
Both eReaders are designed to provide weeks of battery life, which is a significant advantage for users who enjoy reading on the go. However, specific battery performance metrics are not provided for either device. Given that both are designed primarily for reading, users can expect extended use without frequent recharging. This characteristic is essential for avid readers, making both options appealing for long reading sessions.
Additional Features
The Bigme B7 Color includes a stylus for note-taking and supports document annotation, which adds to its versatility as a digital tablet. It also features customizable keys for enhanced efficiency. In contrast, the Kobo Libra Colour offers compatibility with the Kobo Stylus 2 (sold separately) for annotation, and it has a user-friendly design that includes page-turn buttons and customizable font sizes. While both devices offer unique features, the Bigme’s additional functionalities make it a more multifunctional choice.
Water Resistance
A standout feature of the Kobo Libra Colour is its IPX8 waterproof rating, which means it can withstand immersion in water for up to 60 minutes at a depth of 2 meters. This makes it ideal for reading at the beach or in the bath without worry. The Bigme B7 Color does not mention any waterproof capabilities, which may be a deciding factor for users who need a device that can handle moisture. The Kobo's durability in wet conditions makes it a strong choice for outdoor readers.
Which should you buy?
Ultimately, the choice between the Bigme B7 Color and the Kobo Libra Colour depends on your specific needs. If you require a versatile device that functions well as both an eReader and a tablet, the Bigme B7 Color, with its higher price of $319.97, offers features like 4G calling and extensive storage. However, if you are looking for a budget-friendly, waterproof eReader tailored for reading, the Kobo Libra Colour at $229.99 is an excellent choice. Its compatibility with the Kobo ecosystem and glare-free display makes it particularly appealing for dedicated readers.
