I have the LCS-CSQ Amazon ordered this week (with shipping for 11.95) and am very glad that I chose for this bag. I've looked at all the bags from Sony and then opted for the CSQ (the reviews of the previous speakers convinced me, for which I am grateful to them). For the W-models, I can assure, this bag is perfect! One small thing I want to mention: the bag can not hang around the neck of one, but only at the belt. For me personally, this is more than adequate, since I do not like running around like a tourist ...
