Picked these up just now from Sennheiser store in Sydney. In-store price is $99.95 but they matched their online price.
For those wanting latest BT and longer battery life these aren't for you (has BT 4.2 and small 6 hour battery).
It's a great price for the signature Sennheiser sound and 24 month warranty though.
A couple of other deals knocking about..
Looks like this one is in-store only.

Pretty reasonable deal if you had a matching pair of ears.
