so I remembered the FCC database exists and it reveals Some Info abt the new teenage engineering thing:

it's a handheld device called the OB-4 and it has 2 bluetooth transmitters

that's all, unfortunately, as they submitted a request for confidentiality

there is one more interesting thing: the label design they submitted to the FCC claims that it's a Bluetooth Speaker

although that might be a placeholder? idk how that process works
