Can These Speakers be Synchronized With Other Devices?
Unless mentioned explicitly in the product description, these speakers can't synchronize with other devices.
Are They Portable?
No, these speakers aren't portable. They are wired and should be plugged into a power supply to work correctly. Some tiny models could be easy to move due to their small size, though.
Do They Come With a Subwoofer?
Usually, when a model features a subwoofer, we mention it in the product description. The models that come with a subwoofer are easily recognizable by their nomination ending by .1 like 2.1, 5.1, or 7.1.
