I'm a huge fan of thr Poly Voyager Focus 2 headsets and have bought several over the last 4 years for work/car travel. Their noise canelling is amazing and the sound is crystal clear, for both the speaker and the listener, but after spending 10+ hours a day wearing them for years, my ears are ready for some over-the-ear style headphones. I've tried several, including the $400 versions by other brands, but for remote work, the sound was terrible and the nosie cancelling did not work well for Zoom-type meetings in noisy environments.I'm elated to say that as nervous andnai was about straying from the Polycom Voyager Focus 2 model, these have been awesome and my ears are soooooooo happy!!!! I really miss the extended mic, but it's been a good trade off and the mute button is easily reached so, all in all, this is a worthy successor and I'll be keeping them.
