Hello,
if you haven't bought the MR2 yet, don't buy it, let alone a second one.
I don't know if pairing works without a router. I only have one and it pairs miserably. Be it via Bluetooth, WLAN is a disaster. In the high-end WLAN, it uses the weak 2 GB connection and breaks off constantly. The quality is China junk and even that is sometimes better.
