Sennheiser introduced its Momentum cans back in 2012, and then tacked on an on-ear option about a year later. Both of those are quite capable headphones, but wireless is all the rage these days, so to keep pace with the competition, the company is cutting the cord. Here at CES 2015, Sennheiser is debuting wireless models for the over-ear and on-ear versions of the Momentum family. Both feature NFC pairing, Bluetooth connectivity with apt-X tech to handle "superior unaltered sound." What's more, the pair packs in NoiseGuard active noise cancellation to drown out the ambient clamor during 22 hours of playback before needing a charge. There's also version 2.0 of the wired varieties, and the entire series now features a folding design for easy storage. No word on pricing or availability just yet, but you can expect the two Momentum Wireless models to arrive in both black and ivory color options.
