What is the minhag by the Sephardim in terms of listening to music during the 3 weeks?
Answer:
Although the official halachah of the Shulchan Aruch is that there is no need to avoid music until the Nine Days, many Sephardim today are careful to follow the Ashkenazi custom (see Ben Ish Chai, Devarim 4).
In practice, each follows the custom of his own community.
