Summary: I didn't exactly buy these for plane journeys, but figured I'd give them a go at half price. It's a decent enough quality, but I expected more for the RRP, perhaps they'll sound better on an amp, but at least they don't boost the bass like "some" headphones to distort the quality.
Summary: I have been using these for 6 months. They are -comfortable - light - come with a good case - not too quick to use up batteries Overall a great purchase. If I had one request, it would be that they were a little slimmer, but you get that with some of the more expensive models.
Summary: I have both these and the BOSE QC15. The BLAUPUNKT came from Amazon, but I got the BOSE ones for $260 whilst away with work. The quality of both seems about the same. The BOSE has a bespoke fitting for the cable and this can be a standard one or the Apple one.
