I think so.
vivo s series has not been supporting double loudspeakers, he uses a single speaker
Second, the difference between double sound and single sound
Single speaker
For the user to bring a speaker external, does not bring three-dimensional surround sound for the user, while watching a movie, we can not distinguish the left and right sound channels in a single speaker, can not bring users a better viewing experience.
The sound quality of the vivos is still pretty good.
