Developments: 2. K-pop group LE SSERAFIM has faced recurring allegations regarding their live vocal performances during August 2026. The controversy began following the group’s appearance at the Summer Sonic Festival in Tokyo, where clips from an official livestream led to accusations that members were using pre-recorded vocals. Critics noted instances where members Yunjin and Sakura turned their microphones toward the audience while vocals remained at a consistent volume, prompting claims that the group and their label, HYBE, were using heavy backtracks. Supporters countered that the issue might stem from the livestream audio mix, citing audience videos that appeared to capture live vocals. Similar allegations surfaced following the group’s performance at the K-World Dream Awards on August 27, where they received the ‘Best Artist — Female’ Daesang. Social media users highlighted footage of Yunjin holding her microphone away from her mouth while the backing track continued. While critics used the clip to question the group’s live abilities, fans argued that the use of backing tracks is common during award shows and that staging factors can influence live sound. ## Timeline ### 2026-08-28: LE SSERAFIM's Yunjin faces lip-syncing allegations LE SSERAFIM’s Yunjin faces lip-syncing allegations following a performance at the 2026 K-World Dream Awards, sparking debate between critics and defending fans. 2 sources. https://clstr.news/cluster/le-sserafims-yunjin-faces-lip-syncing-allegations ### 2026-08-17: LE SSERAFIM faces vocal controversy at Summer Sonic 2026 LE SSERAFIM faces allegations of using pre-recorded vocals during their Summer Sonic 2026 performance in Tokyo, sparking debate between critics and fans regarding the livestream audio mix. 3 sources. https://clstr.news/cluster/le-sserafim-faces-vocal-controversy-at-summer-sonic-2026 --- Cite as: LE SSERAFIM live vocal controversies.
