A:AnswerYou can buy two of these guys and they can connect as stereo. I have two myself and it sounds amazing. Honestly this Flex sounds great solo as well. Even though by itself it is a mono speaker I think it does do some separation effects through its DSP technology (digital signal processing). Mono or Stereo music sounds freaking amazing. FYI- sounds better on its back imo.
A:AnswerUnfortunately it is common now with a lot of gadgets to receive the cord only like this. Make sure you get a base to plug the correct type of usb that the cord requires, if you don’t already have one laying around that is.
A:AnswerNo. All audio is connected via Bluetooth, the cable is only used for charging.
Use the Bluetooth in your MacBook Air to connect to the Bose speaker.
