Recommendations

For best results, keep the speaker clear of obstructive coverings that could muffle the 360° sound, update firmware via the UE | BOOM App when available, and avoid exposing the charging port to debris. When connecting multiple speakers with PartyUp, place units evenly around the listening area for a balanced sound field.
