Display Quality

The Bigme B7 Color eReader boasts a superior display resolution of 300PPI, while the OBOOK5 features a 219PPI display. This significant difference in pixel density means that the Bigme can deliver sharper text and more vivid images, enhancing the overall reading experience. The Bigme’s color E-ink Kaleido 3 technology allows for a more vibrant visual experience, making it particularly appealing for those who enjoy illustrated books or require visual aids. In contrast, the OBOOK5 provides a glare-free reading experience, ensuring comfort even in bright sunlight, which is an important feature for outdoor reading.

Storage and Performance

When it comes to storage and performance, the Bigme B7 stands out with its impressive 128GB of internal storage, allowing users to store approximately 70,000 books. It also features an Octa-Core processor, ensuring smooth multitasking and fast performance. On the other hand, the OBOOK5 comes with a modest 32GB of storage, which may be sufficient for casual readers but limits options for those with extensive libraries. While the OBOOK5 offers quick page turns, the Bigme’s advanced CPU and larger storage capacity make it a better choice for power users who need speed and space.

Connectivity Options

The Bigme B7 Color eReader excels in connectivity with its support for 4G calling and both 2.4G and 5G WiFi, as well as Bluetooth capabilities. This makes it a versatile device for users who need to stay connected on the go, allowing for a seamless reading and communication experience. Conversely, the OBOOK5 focuses primarily on WiFi and Bluetooth connectivity, lacking cellular options. While this may suffice for most users, those who require constant connectivity may find the Bigme more appealing due to its range of options.

Battery Life

The OBOOK5 is designed for long-lasting use with a battery life that can extend for weeks on a single charge. This makes it an excellent choice for travelers or those who prefer to read without the worry of frequent recharging. Meanwhile, while the Bigme B7 also offers a substantial battery life, specifics regarding its longevity are not available. However, the capability of the Bigme to support various functions such as 4G calling and its performance-driven features might suggest a slightly more demanding power requirement, leading to a potential trade-off in battery longevity.

Additional Features

In terms of additional features, the Bigme B7 offers a built-in stylus for note-taking and document annotation, catering to users who value interactivity and productivity in their reading experience. It also includes a 5-megapixel rear camera, which adds to its multifunctionality. On the other hand, the OBOOK5 provides a built-in speaker for audiobooks, seamlessly integrating listening with reading. While both devices cater to different user preferences, the Bigme’s emphasis on productivity features positions it as a more versatile tool for those who need more than just an eReader.

Pricing and Value

In terms of pricing, the Bigme B7 Color eReader is priced at $319.97, which is about 255% more expensive than the OBOOK5, available for $89.98. This substantial price difference reflects the advanced features and capabilities of the Bigme, such as its high-resolution display and extensive storage. For budget-conscious consumers or casual readers, the OBOOK5 offers an excellent entry point into e-reading without compromising on essential functions. However, for those who see value in advanced technology and enhanced reading capabilities, the investment in the Bigme may be justified.

Sales Ranking

The sales rank of each device also provides insight into their popularity among consumers. The Bigme B7 has a sales rank of 66,991, while the OBOOK5 ranks significantly higher at 32,994. This suggests that the OBOOK5 is more popular among buyers, likely due to its lower price and sufficient features for casual readers. However, the Bigme’s advanced features may appeal to a niche market willing to invest more for enhanced performance and versatility.

Which should you buy?

Choosing between the Bigme B7 Color eReader and the OBOOK5 ultimately comes down to your needs and budget. If you are looking for a high-resolution display, extensive storage, and additional features like 4G calling and note-taking capabilities, the Bigme B7 is the way to go. However, if you prefer a more affordable option with a solid reading experience and long battery life for casual use, the OBOOK5 is an excellent choice. Consider what features are most important to you, as each device serves different types of readers effectively.
