Can I Bring a Speaker on a Plane? What about a Carry-on?

Short Answer: Is a Bluetooth/Portable Speaker Allowed on a Plane. The shortest answer we can give is that a typical bluetooth speaker is allowed on a plane, as long as it doesn’t exceed the size limits set by the airline. According to TSA (Transportation Security Administration), a U.S. government entity that regulates airport and airline security, portable speakers are allowed on both carry-on luggage and checked luggage, provided that they aren’t too large.
