Adam participated in
season 7 of
Kokhav Nolad (), a popular
Idol show in Israel until a blogger revealed that Adam was just 15 years and 7 months when he applied, while the minimum age is 16. Adam withdrew from the competition mid-way through the season.
Zvika Hadar, host of the show, responded by saying: "The important thing is that Omer realized his mistake, apologized and took the right decision. Our role is to provide equal admission to all contestants, we cannot compromise on this case." On June 15, 2011, Adam appeared in a live show attended by thousands in
Caesarea Maritima, becoming the youngest artist to headline there. Adam performed at the Opening Ceremony of the
2017 Maccabiah Games on July 6, 2017. Adam had the biggest selling song in Israel in 2017–18 with "Two Crazy People" (), surpassing Eurovision 2018 winner "Toy" by
Netta Barzilai.
Stav Beger was a key producer in both songs. In 2019, Adam, then considered Israel’s most popular recording artist, turned down an offer to appear in the
Eurovision Song Contest 2019 in Tel Aviv, as it would involve performing on
Shabbat. In November 2020, Adam joined 39 other Israeli artists to record
Katan Aleinu, a
charity single benefitting hospitals battling the
COVID-19 pandemic. In 2023, Adam moved to Dubai with his previous partner, Israeli model
