Looking for an all-in-one just-add-speakers streamer for my son to take to college

I would not invest a lot of money in a stereo system if my kid was living in campus housing.  Theft is always an issue, not to mention abuse of the equipment by drunk roommates.

I'd be looking at cheap bluetooth powered speakers, or one of the bluetooth Chinese amps and a pair of cheap Dayton Audio speakers.

I know I sound like an old crabby fart, but the kids should be focused on their classes and other activities and shouldn't be spending all their time in a comfortable dorm room.  In fact, the more the dorm room looks like a prison cell, the better.😁

Like Dino and rbertalotto above, I suggest going cheap.  A Fosi BT120A has Bluetooth and ample power output to drive speakers to dorm room levels.  Give him a household chore to complete so he earned it himself.  For speakers, Find a good used pair that fits his room size and musical tastes. 

I'd recommend any of the Edifier powered Bluetooth speakers. I've compared them to the Audioengine speakers and thought the Edifiers sounded much better. https://www.edifier.com/global/product-category/bookshelf-speakers

What about a SONOS Play 1?  Or a pair of them?  

+1 for Bluetooth speaker. It kind a complicated to build and maintain audiophile environment with in college style of life. I suggest something like Harman Kardon HK SoundSticks 4-2.1 Bluetooth Speaker System. Nice build high quality BT system, pretty universal. Could be used with phone streaming or hardwired with computer, provides deep reach regulated bass.
