NOT a high end request! Looking for small CD player w/ Bluetooth output

Forgive me for this.....I'd like to get a CD player with Bluetooth capability for my 45 yr old surgeon son who has your basic mono outboard bluetooth speaker and is now finding himself playing piano in his beachfront Kona home.  OK, wish you were this lucky?  I know I am not...I want to send him stuff he's never heard but need something inexpensive to pull it off.   Any ideas?  Nothing special required here, just not junk.  Surely someone has something like this for their beach house or somewhere.   It's amazing to find him getting into classical piano after facing it for decades with me.  Never too late, I suppose.
