Unboxing and Package Contents
The Bobo VR E3 Pro arrived in sleek packaging, clearly displaying product details and installation instructions. Inside, I found the headstrap, a 10,000mAh battery, an instruction manual, and extra grip materials for the back of the head cup. A USB-C charging cable was also included, completing the package.

The packaging itself was well-designed and informative, a nice touch for the unboxing experience. The inclusion of extra grip materials shows Bobo VR's attention to detail and user customization options. The battery size is impressive, hinting at extended usage.
Installation and Comparison with Bobo VR S3 Pro
Installing the E3 Pro was straightforward. Unlike the S3 Pro's slide-on design, which left marks on the headset over time, the E3 Pro uses a secure snap-on mechanism. This ensures a clean fit and protects the headset's finish.
The installation process was easy, even for someone familiar with the S3 Pro. The snap-on design is a significant improvement over the slide-on design found in its predecessor, offering both convenience and protection for the headset.
3.5mm Headphone Jack and Digital Display
The standout feature is the integrated 3.5mm headphone jack, a necessity for the Meta Quest 3S which lacks this port. It works flawlessly with various headphones, providing a direct audio connection without the need for Bluetooth or other wireless solutions.

The small digital display on the headstrap shows the battery percentage, offering a quick way to monitor power levels. A single button on the display allows you to easily turn the battery on or off, which is useful for conserving battery life.
Comfort, Design, and Build Quality
The Bobo VR E3 Pro is a top-strap design, requiring a facial interface for a comfortable fit. The materials are high-quality, using thick pleather that is easy to clean and maintain.

The overall design is sleek and well-balanced, thanks to the placement of the battery. The adjustable straps are comfortable and ensure a secure fit for various head sizes. The snap-on design prevents marking of the headset.
Pivot Points and Battery
While the headstrap is comfortable, the pivot points are stiff, making adjustments difficult. This is a design flaw that could be improved, as it impacts the ease of putting on and taking off the headset.

The 10,000mAh battery is a highlight, offering long usage times and easy hot-swapping. The battery includes a low-battery warning system with beeps to alert the user.
Final Verdict
The Bobo VR E3 Pro is a good headstrap, particularly for Quest 3S users needing a 3.5mm headphone jack. The 10,000mAh battery, digital display, and easy-to-clean materials are positive aspects.

However, the stiff pivot points are a significant drawback, hindering easy adjustment. While comfortable once adjusted, putting it on and off requires more effort than other headstraps. Overall, it's a valuable accessory for the Quest 3S, but the pivot point issue should be considered.
