all high notes are well produced and properly tuned
Batteries performance on these headphones is superb
travel-friendly design and features

Sound systems is good with these headphones
The battery life is pretty good and having a removable battery means
new ways of thinking
new connections
and new industries

keeps a good seal and feels great all day
are solid to the feel and very well constructed with the earphones being able
The design is very flexible and you can carry it with you anywhere
best quality under wired connection
quality was excellent overall
Controlling is very easy to operate

lacking a strong isolation performance and their sound quality
lack of NFC pairing with the second-generation headset
discontinuation makes it hard to find
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
drowned out the entire sound of the props
the bass sound muddy and exaggerated
volume did not seem as loud when I was not on the airplane
Quite complicated controls had me checking the manual several times
noise cancelling clips badly during takeoff on a plane
Expensive
8 hour battery life is just not enough for a travel headphone
The batteries that are additional are not cheap
Controls can be confusing RTFM before use
The audio suffers from no discernible degradation before it reaches your ears
They're too quiet for truly noisy situations
$600 mark is just a bit tough to swallow
No cherry-picked units sent by brands
sound quality lacks a little excitement
a little unstable for high-intensity exercises
soft case fabric will not shield the headphones from hard falls

Review: Sennheiser MM 550-X

You may recognize these Sennheisers, since we reviewed the previous model about a year ago. But they’ve been updated recently with some new firmware that gives them better audio. They look exactly the same, but there’s a new model number: They’re now called the MM 550-X.
