Lucy Charles-Barclay x H2O Audio 🤝

The LCB Edition TRI 2 PRO is here, and we're stoked to finally show you.

Months of work and testing with Lucy — a limited edition color, designed by her, in the pair she's trained in through this whole build.

Swim, bike and run. Take your music with you. Load it onto the headset before you get in and leave the phone in the bag. Bone conduction, so you still hear the pool, your coach and the road home 🎧

Lucy, thank you for making this one with us 💙

THE START LINE JUST MOVED

We were set to dive in on 6 August—but we’re taking one more lap.

🥈 Second place never felt this good.

Huge congrats to Toa on a phenomenal finish at the M2O Race! Crossing that channel takes grit, and Toa says it was the music that carried him through the toughest stretches out there — soundtracked by the H2O Audio Tri 2 x Florence headphones, built to keep the rhythm going no matter how rough the water gets.

Hit play to hear Toa break down race day and the mindset that got him to the podium. 🎧🌊

Beautiful sport, great humans. We are on board 🙌🏻
