- No question, these are the "elite" over-ear headphones. They're so comfortable and so effective. Worth every penny!+1. I use these while working and love them. I'd never venture into an open office type environment without them. I've had both the wired and wireless versions. Much prefer the wireless, they are more comfortable and make it easy to get up and walk around without taking them off.
- 18-20 hour battery life; simultaneous pairing with multiple devices (e.g. audio from phone / laptop both go to headphones); ability to use a wired plug; excellent noise cancellation; great voice call fidelity; best-in-class Sennheiser audio quality; comfortable (worn many hours per day)
