it s a requirement for all headphone companion apps to locate your headset
you cannot use the app unless you grant location permissions
Smart Control app doesn t afford extensive control
lack of NFC pairing with the second-generation headset
discontinuation makes it hard to find
$600 mark is just a bit tough to swallow
The batteries that are additional are not cheap
Quite complicated controls had me checking the manual several times
8 hour battery life is just not enough for a travel headphone
noise cancelling clips badly during takeoff on a plane
Expensive
sound quality lacks a little excitement
soft case fabric will not shield the headphones from hard falls
a little unstable for high-intensity exercises
No cherry-picked units sent by brands
lacking a strong isolation performance and their sound quality
The audio suffers from no discernible degradation before it reaches your ears
They're too quiet for truly noisy situations
Controls can be confusing RTFM before use
