The Quran Group Recitation is deemed permissible among Sunni scholars. This canonical position, is confirmed by many fatwas and opinions of famous scholars, including Abu Hurayrah, Imam al-Nawawi, Ibn Hajar al-Haytami, Imam ash-Shirvani, and others.
Ibn Hajar al-Haytami in his book "Tuhfat al-Mukhtaj" writes:
"يسن تحسين الصوت بقراءة القرآن, وأما تلحينه فإن أخرجه إلى حد لا يقول به أحد من القراء حرم وإلا فلا على المعتمد ... الماوردي: إن القارئ يفسق بذلك, والمستمع يأثم به"
“It is advisable to read the Quran in a beautiful voice. As for the chanting reading of the Qur'an, this is permitted. If the execution goes beyond the rules of reading (tajwid) of the Quran in a way that none of the readers allowed, then this is prohibited. Imam Al-Mawardi says that reading the Quran not according to the rules established for this makes the reader a fasik (a wicked, and this is a great sin), and the one who listens to such reading falls into a sin (small).
