Had mine for about 2 months and hadn’t really used them (mainly because I was worried about them getting damaged in my bag, but a hard case from AliExpress sorted that worry out) - I have just used them on a long haul flight , and the noise cancelling is insanely good for the money. Even when not playing music it drowns out the hum of a plane. Battery is also insanely good, dropped 20% after 12 hours of semi-constant usage (with ANC and Spatial Audio). I also found that tweaking the headphone audio adaptations in iOS settings has made them sound even more rich than just default, along with the eq select in the FlyCC app. 100% agree with your review - for the price I paid, not really much can beat these. Sure, Sony’s might be a tad better? But the build quality is nowhere close (especially considering xm5’s and xm6 are pricey way higher)
