Good protection for the S2 plus. After a while from time to time agree, thus removing the accumulated dust betw. Cover and Smartphone. One should keep in mind that an Aux cable no longer fits with a big head when using the shell (ie the AUX audio cable of a TFT monitor). However, the original headphones of S2 plus still fit! What can I do so that even large AUX cable fit: I have cut off with a pair of nail scissors a little the protective sheath around the AUX input, and then slightly filed down (with a nail file). Then all AUX cable fit perfectly :-)
