We had in our garden created a seat (with fireplace) and sometimes wanted to listen to music - but but "need to move" no power cord. That's why I was looking for wireless speakers. This speaker set I have what you wanted! I had to also ordered my batteries that I used in a loudspeaker. At first I heard a "strange music - not my !!!". However, with the scan button you can change the frequency and it sounded "my music". My wife and I are very satisfied!
