Dimension comparison
Display Quality
The Bigme B7 Color eReader features a 7-inch E-ink Kaleido 3 display with a resolution of 300 PPI, providing a vibrant reading experience that's particularly beneficial for colored content. In contrast, the Kobo Libra Colour also boasts a 7-inch Kaleido 3 display but focuses on glare-free reading, ensuring visibility even in bright sunlight. While both devices offer excellent display technology, the Bigme's color capabilities may appeal more to those who enjoy illustrated materials or comics. The choice largely depends on whether you prioritize vivid images or a glare-free reading experience.
Storage and Performance
The Bigme B7 Color eReader comes equipped with 8GB of RAM and 128GB of internal storage, allowing it to house approximately 70,000 books, which is significantly more than the Kobo Libra Colour's 32GB storage capacity that holds about 24,000 eBooks. This means that if you are a voracious reader needing extensive storage for your library, the Bigme B7 provides a clear advantage. Additionally, the Bigme's advanced Octa-Core processor promises smooth performance, making it a suitable choice for multitasking and utilizing various applications.
Connectivity Options
When it comes to connectivity, the Bigme B7 Color eReader shines with its 4G calling support, allowing users to stay connected on the go. It supports both 2.4G and 5G Wi-Fi connections, alongside Bluetooth, which provides versatility in how you access content and connect with other devices. On the other hand, the Kobo Libra Colour does not offer 4G connectivity but allows you to borrow eBooks from local libraries via OverDrive, which can be a significant advantage for users who prefer borrowing over purchasing. Depending on your connectivity needs, either device has advantages that cater to different preferences.
Battery Life
Battery life is a critical factor for e-readers, and both devices offer impressive longevity. The Bigme B7 Color eReader promises a battery life that lasts for weeks, making it highly suitable for long reading sessions without the constant worry of recharging. While specific figures aren't provided for the Kobo Libra Colour, it also boasts weeks of battery life. Users can expect both devices to sustain their reading habits without frequently needing to plug in, which is essential for on-the-go readers.
Design and Ergonomics
The design of the Kobo Libra Colour embraces ergonomic aspects with page-turn buttons and a lightweight build, making it comfortable to hold for extended periods. Its design also includes left/right screen rotation and margin customization, enhancing the reading experience. Conversely, the Bigme B7 features a modern aesthetic with a stylus for note-taking and annotation. While both designs cater to user comfort, the Kobo's dedicated hardware buttons may appeal to traditionalists who prefer tactile feedback while reading.
Waterproofing
The Kobo Libra Colour has an IPX8 rating, meaning it can withstand being submerged in water for up to 60 minutes at depths of 2 meters. This feature is perfect for readers who enjoy relaxing by the pool or in the bath. Unfortunately, the Bigme B7 Color eReader does not mention any waterproof capabilities, which could be a deal-breaker for users who prioritize reading in wet environments. If waterproofing is crucial for your reading habits, the Kobo Libra Colour is the clear winner.
Audiobook Features
Both the Bigme B7 Color eReader and the Kobo Libra Colour offer audiobook compatibility, but they do so in different ways. The Bigme B7 includes audiobook features as part of its Android operating system, allowing for a versatile multimedia experience. In comparison, the Kobo Libra Colour directly supports Kobo Audiobooks and comes with a free 30-day trial of Kobo Plus, which provides unlimited access to eBooks and audiobooks. If audiobooks are a significant part of your reading experience, the Kobo Libra Colour may offer a more integrated solution.
Which should you buy?
In conclusion, your choice between the Bigme B7 Color eReader and the Kobo Libra Colour largely depends on your specific needs and preferences. The Bigme B7, priced at $319.97, offers superior storage capacity, advanced connectivity, and a powerful performance that might appeal to tech-savvy readers. However, it lacks waterproofing, which the Kobo Libra Colour offers at a more economical price of $229.99, making it a solid choice for those who prioritize durability and ease of use. If you value vibrant color displays and extensive storage, the Bigme B7 is worth the investment. Conversely, if you’re looking for a reliable, waterproof device with integrated audiobook support, the Kobo Libra Colour stands out as the better option.
