No, the 8k+ has the MAS (modular audio strap) with basic speakers. These speakers are open to the air similar to what has been done with the Oculus Rift and Quest. There is also a deluxe MAS that has speakers that extend down over your ear.
Just to note, the default speakers in the Modular Audio Strap aren’t similar to the Oculus Rift or Quest at all. Those things have small speakers within the headset that pushes the sound out along the strap, while the Modular Audio Strap has decent-sized speakers sitting on it near your years. Looks more like the Valve Index speakers than the crappy Quest/Rift S speakers.
