I recently bought some Logitech G930s for my daughter to use with my computer.  I didn't realize how much I'd like walking around the house with the headphones on.
So now I'd like to get something better.  I'm looking at the Sennheiser RS160 & RS170.   I'm also looking at the BOHM bluetooth and finally the MEE audio Air-Fi Matrix2.  The MEE audio supports aptx and the Senns use kleer.  
 
Does anyone have any personal experience with any of these headphones?  Any suggestions for the $200 price range?

Does the Bohm or Logitech G930 have side tone that work well with an iPhone?

(Side tone is the ability to hear oneself speak in the earpiece most always found in landline handsets.)
