Had my eyes on these since they were released a couple of months ago and it's the first time I've seen it on sale. Rather good discount too which puts it in the Sony XM5 discounted price range. Blue and Grey versions also on sale for the same price.
From reviews, they appear to have better soundstage than the XM5 but noise cancelling isn't as good. Either way, it will be a decent upgrade from my first gen Sony 1000x.
Don't forget 2% Cashreward cashback.
How are they compared with Momentum 3?
