Those are the QC20. Because they have the blue stripe they could be android or apple version (I think the android has a "S" printed on the remote.
There's not much use for a manual. It has on/off button on the battery module. Play/FF/RW and Vol+/- buttons on the remote (The one on the side of the remote is the "aware mode" letting ambient noise is)
Thanks for posting and welcome to the Bose Community!
