HAKII Boulder II

Whether you're hiking with friends or spending a weekend at a campsite, outdoor adventures are better when you can enjoy music and communicate easily with your group. But when everyone starts moving in different directions, staying in touch can become less convenient.

HAKII Boulder II brings portable audio and long-range voice communication together in one wearable speaker. Its compact design lets you carry your music without keeping a speaker in your hands, while the built-in intercom function helps you communicate with companions over longer distances.

With multiple wearing options and outdoor-ready protection against water, dust, and accidental drops, Boulder II is designed to fit naturally into your adventures.

Key Features of HAKII Boulder II

Stay Connected with Up to 3 km of Real-Time Communication

More than just a portable speaker, HAKII Boulder II features real-time voice communication with a range of up to 3 km.

Its push-to-talk (PTT) function allows you to send voice messages using a simple button control, making it easy to communicate when your companions are no longer within ordinary speaking distance.

Whether your group has spread out along a hiking trail or you're coordinating activities around a campsite, Boulder II gives you a convenient way to stay connected without relying solely on shouting across the distance.

The communication range may vary depending on terrain, obstacles, and surrounding conditions.

Powerful Audio in a Compact, Wearable Design

HAKII Boulder II combines a compact form factor with powerful sound designed for outdoor listening.

Instead of carrying a bulky speaker, you can attach this small device to your clothing or backpack and keep your music close as you move. Its wearable construction makes portable audio a natural part of your outdoor activities.

For an expanded listening experience, Boulder II also supports True Wireless Stereo (TWS) pairing, allowing two compatible speakers to work together wirelessly. This creates a broader sound experience than using a single speaker alone.

It's a practical combination of portability and audio versatility.

Multiple Ways to Wear and Carry

A portable speaker should be easy to carry, but it should also adapt to how you move.

That's why Boulder II supports magnetic attachment, a rear clip, and lanyard-style wearing options. You can choose the carrying method that works best for your clothing, gear, or activity.

Its ergonomically shaped body is also designed to be comfortable to grip when you prefer holding it directly.

Attach it to your backpack while walking, wear it on your clothing to keep your hands free, or pick it up whenever you need it. The flexible design makes Boulder II easy to incorporate into different outdoor situations.

IPX7 Waterproof Protection and Outdoor-Ready Durability

Outdoor equipment often faces unpredictable conditions, from sudden rain to dusty environments.

HAKII Boulder II features IPX7 waterproof protection, along with a design that incorporates dust and drop resistance.

The IPX7 rating indicates resistance to temporary immersion in water under specified test conditions. It does not mean the device is immune to all water exposure or physical damage.

Together, these protective features make Boulder II a practical companion for hiking, camping, and other activities where ordinary indoor speakers may be less suitable.

A Low-Temperature Battery Designed for Cold Conditions

Cold weather can present challenges for battery-powered electronics, particularly during winter outdoor activities.

Boulder II is equipped with a low-temperature battery rated for environments down to -30°C, making it suitable for activities in cold conditions.

This battery design reflects the product's focus on outdoor usability, extending its appeal beyond warm-weather adventures.

For people who enjoy spending time outdoors throughout the seasons, it adds another useful dimension to the speaker's versatility.

Conclusion

HAKII Boulder II brings together two valuable outdoor features: portable music and convenient long-range communication.

With its wearable design, multiple attachment options, real-time push-to-talk functionality, and outdoor-ready construction, it offers a practical solution for people who want to enjoy audio while staying in touch with their companions.

Whether you're exploring a trail or spending time together at a campsite, Boulder II makes music and communication easier to carry wherever your adventures take you.
