This is the best home-office headset you can buy. I used an older version from Plantronics for over a decade and decided to get a new one. Why so good? It connects to THREE devices simultaneously, your landline (if you still have one), your cellphone and your computer. So no matter what rings, no matter which device I want to use, you have one single headset. Range is UNBELIEVABLE and lasts all day without having to recharge. This newer version also has full stereo (older model was mono) so it sounds great when watching YouTube videos, etc.Whatever "rings" you just press the button on the headset and you're talking.Before I found these I had different headsets for my cellphone and my computer and the telephone handset for my landline, and it was a pain to figure out which headset to grab for each call.I still have the handset lifter (for landline phone) from my older headset, it was super handy for lifting the handset off the phone when you wanted to answer a call, but I don't use that anymore as I don't have a landline anymore.I've had 4 or 5 friends buy this headset based on my strong recommendation.This is a "cry once" purchase. It isn't cheap (cry once) but you'll be happy with it for many years to come, and won't be replacing it in 6 or 12-mo.I have purchased one for my home office and one for my work office.
