All-day comfort for constant telephone use

I've been in business for 48 years & have had a lot of chances to make my office more productive using various wireless versions. This D904 headset (I use the single side, over the head model) makes it easy to comfortably wear the headset all day while providing the freedom to walk away from my desk to fetch files or speak with staff. I feel it is of great value & the warranty period is second to none. I choose to not write reviews, but this one was worth it, especially given the fast response by the company. 5 stars!
