I've fallen in love with the Momentum headphones Sennheiser launched a few years ago. They're my go-tos: the cans that sit on my desk everyday. Usually, I don't care that somebody made existing headphones wireless or that they managed to make them noise cancelling. Bluetooth? Yawn. Noise cancelling? Whatevs. But I'm posting the Momentum wireless as an exception because I'm legitimately excited that they exist.
Like the old wired Momentums, the new ones come in both on-ear and over-ear versions. As mentioned above the headphones are Bluetooth so that you can play music wirelessly. They've got NFC so that you can tap and pair easily. Besides, their wireless connectivity, the headphones also have an active noise-cancelation.
At this time, there's not much more to say about the headphones without actually trying them. They look to be basically be wireless recapitulations of the existing models: the on-ear are smaller with smaller drivers. This time around, both the on-ear and over-ear versions fold up.
Hopefully the new Momentums will have the same balanced detailed sound as the wired versions. One potential red flag is all of the electronics inside of these cans. The reason I use the Momentums at my desk all day is that they're so lightweight.
It's worth noting that Sennheiser is also announcing a wireless version of the Urbanite series headphones the company announced last year at IFA. These headphones are a better sounding low-end headphone that's supposed to compete with Beats.
