April 3–5 | Oceanside, California

We’re headed a few miles from the office, and we’re bringing the energy with us. H2O Audio is thrilled to be exhibiting at the IRONMAN 70.3 Oceanside Expo from April 3rd through race day on April 5th, and we’ve got a lineup that’s just as exciting as the race itself.

Whether you're racing, spectating, or just soaking in the energy of the IRONMAN community, stop by our booth to:

🎧 Try Before You Buy

Get hands-on with our lineup of waterproof and multi-sport headphones—including our newest TRI 2 PRO series. We’ll have demo units available, so you can experience the sound quality and fit that elite athletes rely on.

🎟️ Enter the Ultimate Scavenger Hunt Giveaway

We’ve partnered with none other than Lionel Sanders for a special scavenger hunt giveaway. Lionel will be hiding golden tickets in H2O Audio bags around the course—find one, and you could win a free pair of TRI 2 PRO headphones. Follow Lionel's social media closely for clues on where to look!

🤝 Special Booth Appearance from Lauren Brandon

We’re also teaming up with our partners at Team Varlo, and we’re excited to welcome retired pro triathlete Lauren Brandon to the booth. Lauren will be stopping by for a giveaway and meet-and-greet—a great chance to connect with one of the sport’s standout women.

💸 Exclusive Event Pricing

Come visit us during the expo for event-only discounts and special offers. Whether you're prepping for race day or just curious about our products, we’ve got something for every level of athlete.


This is a weekend we’ve been looking forward to—and we’re excited to connect with the endurance community in person. Follow us on Instagram (@h2oaudio) to stay up to date on scavenger hunt announcements, booth activities, and everything happening at Oceanside.

Good luck to all athletes racing—we’ll see you at the finish line.
Go Beyond.
