I have been using hte Sony Ericsson LiveSound headphones that I got with my Xperia Ray for the last couple of weeks. First I actually used them with my Ray but later I switched them over to my Xperia Pro when I recieved it. Sony Ericsson describes these headphones as tangle free and that is exactly what they are.

Even when you have them in your pocket and pull them upp they work without a hitch. From experience I can tell you that I have used way to many headphones which  got tangled up in my pocket and as a result I have later stood there for a couple of minutes trying to untangle the headphones.  I have so far been using these headphones daily and I have been really impressed with the quality from them, both when watching movies but also when I am listening to music. I have what I would call a diverse music taste but what I have noticed is that these headphones works with whatever type of music that you are currently playing on your headphones.

Here is actually a really good clip by Sony Ericsson developers channel showing of the headphones and how well they work

But what makes these headphones different from the other headphone on hte market is the LiveKey button, which allows you to start an application straight there from your device. For example if you are at a party you can hit up the button and start track ID to see what type music it is that is currently playing. Honeslty form what I can see the possibilities are endless with these headphones. If you are looking for a pair of headphoens these are really well worth the price and if you pick up an Sony Ericsson Xperia Ray you can also get one of these pair of headphones included with your device.
