How do I use my laptop to operate a speaker in another room of my apartment?

Or. What speakers can do that. My laptop has Bluetooth.

Which connections or connection options have the speakers.

So I would still want to buy the speakers. Although I own which (3.5 mm). But it will probably not work. On my laptop, I would like to connect even if possible, no cable.

Bluetooth would be ideal.

Well, in doubt with a cable. You can put them in another room, does not speak against it.

Depends on the class being used (class 1-3).

Class 1: 100 mW, up to 100 meters range, many Bluetooth USB sticks use them
Class 2: 10 mW, up to 50 meters range, many smaller Bluetooth USB sticks use them
Class 3: 1 mW for energy saving, up to ten meters range

However, practice shows that this can only be achieved under laboratory conditions.

For me it is enough with a bit of noise and a little 10m inside an apartment.

One can avail themselves to range increase of a Repeater. In addition, it has the advantage of using multiple devices at the same time.

Personally, I use the BW-107 Bluetooth and have 3 JVL boxes on it. Thus, I reach all rooms with various old building walls in between.

Cost was 23 euro.
