N-Sonic debuted on October 6, 2011 with the EP We Are SuperBoys, with a lineup of 5 members: J-Heart, Eun-ho, Jong-wook, Bong-jun and Choi Byul. Without being able to achieve great success in Korea^{[further explanation needed]}, the group turned their promotion efforts to Japan and China.

On February 3, 2012, N-Sonic held their first concert in Japan, and later that month, on February 16, they announced their fandom name Super Sonic. On February 25, members Eunho and Jonguk left the group for personal reasons.^{[citation needed]} It was later announced that the group would be adding 4 new members, who were revealed on October 10, 2012 to be Zion, Min-ki, Yeon-jun and Si-hoo.

Despite new domestic releases in March and October of 2013, the group continued to promote mainly in Japan, particularly in summer concerts^{[further explanation needed]}. On October 8, 2013, member Yeon-jun left the group for personal reasons.^{[citation needed]} N-Sonic held their first fan meeting and their first solo full concert^{[clarification needed]} in December of the same year, in Japan.

In 2014, N-Sonic released their first single in Mandarin Chinese, representing their debut in China^{[further explanation needed]}. From late 2014 to 2016, the group was mostly active in Japan and Korea, releasing numerous comebacks^{[clarification needed]}. On May 9, 2016, after performing concerts in Japan, the group returned to Korea and immediately cut off communications with their agency, C2K Entertainment, while they sought an attorney to terminate the group's seven-year exclusive contract that they were only approximately three years into.^[1] They reportedly filed a formal request for contract termination on May 17. After failing to appear at multiple scheduled events after the group's return to Korea, C2K Entertainment took legal action against the members of N-Sonic on May 24, asking for compensation for "damages resulting from their breach of contract",^[2] and on June 22, 2017, the Seoul Central District Court's civil affairs department ruled against the plaintiff (C2K Entertainment), ending the conflict.^[3]
