It's in stock so you should be able to receive it in time for Christmas, but maybe check with them first. If you don't want to take the risk you can pay an extra $2 and pick it up from HN/JB/DSE. Or just get them to match it.
This is the cheapest this bundle has been so far (without a coupon). Get the X3 for yourself and give the X2 away as a Christmas present. Or give both of them away.
The Sony SRS-X3 sounds pretty decent. Decent lows, mids, and highs from what I could (just about) hear at JB.
The X2 is quite lacking in lows, but is clear. They both have built-in mics so you can use them as a large speakerphone.
NFC pairing works great. Just tap your phone on top and it pairs.
