Very comfy perhaps not quite so as the BOSE, however better noise cancelling. Sound quality is ok, I wouldn’t say stunning though
Sound quality does depend on how they are talking to your device. The WH-1000MX2 have AAC, aptX, aptX HD, LDAC codecs, so should sound better than OK. The app will tell you what method you’re using.
There should be some decent deals on the WH-1000MX2 coming up as the WH-1000MX3 is being released next week.
