Cardo Replacement Speakers - 32mm

Didn't want blue-tooth speakers with microphone, but that was all I could find. Didn't need a full intercom system. Found these speakers & purchased a UGREEN blue-tooth receiver, £15. Installed speakers, helmet didn't have deep enough recesses, but easily made a bit deeper, charged up receiver, plugged speakers in, paired with WAZE on my phone, tucked receiver behing helmet lining and ran out for a test. Everything worked fine, sound clear, I had to check volume before setting off as admittedly not easy to adjust on the move. May put some "velcro" on receiver to keep it in place, but it didn't move during my test. Well please with a simple solution, and clear instructions for routing.
