Hello all.  I recently bought a MW600 headset for use with my phone which worked incredibly well and paired it up in just s few seconds.  The sound quality was so good I thought I'd buy a little bluetooth transmitter and have it on my MP3 player etc so I just grabbed a generic one off Ebay.  It took a little longer to get it going but it worked great and I am head bobbing while I write this.  My question is though: if I bought another MW600 set can they both listen to the same source?  The transmitter I bought is just off/on/pair and had no screen or extended settings so I am hoping it is the bluetooth that the MW600 picks up rather than the device.  Ultimately I want my girlfriend to buy a pair of these and be able to listen to what I have the transmitter plugged into at the same time as I am.  Would they clash?  Thanks
