Got a 2011 Sony Ericsson phone like me (mine's an Xperia Play) and having difficulties getting a good pair of headphones w/ inline mike to work with them? Are you getting the "not compatible" message? In that case, this is what you need. The right angle plug end is great when the jack is on the side of the phone. I haven't tried the iPhone claim as mentioned in the description, but it worked for my needs. Check this xda post if you want more information on the issues that can crop up with TRRS headphones: [...] It's very informative.
