Go to Home Depot and get 5" dryer hose - the pliable version and insert the cables into these. Although I can't speak to how the sonics will change as they have a wire wrapped in them so one can bend them to position but the low WAF should make her realize just how important your cables are to you. Because of their size I can't see how she can miss them and should have no problem avoiding them... Sonics aside what about that sturdy black pvc pipe, also available from HD???
