New buds in the house!
I also have the QC30 I bought last year so expect a comparison between the 2 in a week or 2.
Initial impressions are very positive.
I was worried about the neck horse shoe since I don't like the QC30's horse shoe. But Sony has nailed this very well. Sony made theirs more U shaped versus the Bose round shape. This makes the Sony less shifty and stable. If you have a larger neck the Bose would accommodate it better though.
Sonically speaking the WI1000X sounds very good with that Sony house sound. I don't think it has the 3D presentation of the Z5 but has similar bass, mids, and treble. I will do a more thorough discussion later after these have been burned in.
I like that I can use these wired or wireless. They immediately paired using Aptx HD and when I switch to prioritize stability versus sound the difference in detail is apparent.
I also found that disabling the noise cancelling never affected the signature, an issue I have with other NC products I own or have owned or tried.
Haven't used these outside yet or for a phone call. Will update as I use them more...
