How do you show up during one of the biggest sporting moments in Europe without being an official sponsor? For the 2024 European Football Championship, JBL wanted to make a real, emotional connection, with players, teams, and millions of fans. The goal: boost visibility and position the JBL PartyBox as the soundtrack of celebration, all without a traditional campaign.

In sport, authenticity travels faster than advertising. That’s why we designed a seeding campaign built around one key idea: if players celebrate with your product, the world will want it too.

We created customised JBL PartyBoxes for national teams including the Netherlands, Spain and Germany. These weren’t just gifts, they were symbols of team spirit and joy, designed to be used, shared, and seen.

The custom PartyBoxes arrived just before the tournament and were embraced immediately. Teams used them in locker rooms, at training sessions and during private downtime. Players shared them organically on Instagram and TikTok, celebrating goals, wins, and eventually, titles.

The ultimate moment? After the final, the Spanish national team placed the trophy directly on top of their JBL PartyBox. No script, no sponsorship, just a genuine moment that said it all.

The campaign generated over 50 million views across social media, and the media exposure value was more than 100 times the original investment. The PartyBox became a symbol of connection, celebration and national pride. Content was picked up by accounts like Euro2024 and 433, and organically reached fans across Europe.

What started as a simple gesture turned into one of the most talked-about activations of the tournament.

Because it didn’t try to steal the spotlight. It supported the moment. And in doing so, JBL became part of the story. With Project360’s network and execution, we created a campaign that felt natural, timely, and impossible to ignore. Thanks to our extensive network, we were able to exceed campaign goals—despite a limited budget and without being an official sponsor.
