In their duo, Winter plays the keyboard, while Styn provides the melodies and vocals. When the brothers first moved to America, they settled in Atlanta, where Styn crossed paths with vocal coach Dionne Osborne, who has also worked with Drake. "Our first months we lived in Atlanta," Winter explained to De Gelderlander. "It turned out that Osborne lived there, too. We just called. She thought it was funny, those brothers from Amsterdam. Of course they have never heard of 's-Heerenberg here. Come along, was the message. And she has been helping us ever since."
In March 2018, Styn posted a heartfelt Instagram post where he thanked his Dionne for helping him hone his talent. "The wonderful woman who I first met about 3.5 years ago in a studio somewhere near Peachtree Street in Atlanta, Georgia," he captioned a selfie of himself and Dionne. "She gave me my first vocal lessons and till the day of today helps me to get better at my craft and pursue my dreams. @dionne.osborne, it was great catching up with you again and thank you for being a source of inspiration and motivation."
