H2O Audio launches SONAR 2 PRO waterproof headphones
Slimmer, smarter, and engineered for peak performance in the water
H2O Audio, the pioneer in waterproof audio innovation, announces the launch of the SONAR 2 PRO, the next evolution in underwater listening. Engineered for swimmers, triathletes, and water-sports enthusiasts, SONAR 2 PRO features a slimmer design, upgraded audio, and intuitive controls — now 40% smaller to reduce drag in the water.
This second-generation model builds on the award-winning SONAR PRO, delivering an immersive open-ear bone conduction experience with less drag, better fit, and enhanced functionality. And with PLAYLIST+ technology, users can record streaming audio from their favorite Bluetooth apps and play it underwater — no phone needed.
“Swimming is not a drag anymore,” said H2O Audio CEO Kristian Rauhala. “We built SONAR 2 PRO for serious athletes who want world-class sound, seamless operation, and total freedom in the water. Every upgrade was shaped by feedback from swimmers and pro athletes. We listened, streamlined, and made it perform better.”
“The SONAR 2 PRO is excellent for swimming; you almost forget they’re there,” said Luke Tasker, multiple IRONMAN 70.3 winner and Hummingbird Collective Racing Team Director. “They don’t move on your head, no matter the pace. And the sound is much better than my other headphones.”
