Case Study

Zeppy Sound Buddy is a groundbreaking portable speaker that combines high-performance audio, sustainable materials, and inclusive design. Built using ARPRO, Zeppy is lightweight, waterproof, buoyant, and extremely durable, making it ideal for outdoor and off-the-grid use.

Problem

Consumers increasingly demand portable speakers that can keep up with active, outdoor lifestyles, yet most available options fall short. Traditional speakers often suffer from significant sound distortion or complete audio loss when exposed to water, limiting their use in aquatic environments. Additionally, many models are bulky, heavy, and not designed to withstand rough handling or impact, making them less practical for travel or adventure. 

Solution

Zeppy Sound Buddy solves the limitations of traditional speakers with a durable, lightweight, and waterproof design made from recyclable ARPRO. It delivers distortion-free stereo sound even underwater and transmits vibrations, allowing users—including those who are deaf or autistic—to feel and connect with music. The speaker is also available in a sustainable version using ARPRO 35 Ocean, made from recycled maritime waste, reducing environmental impact.
