A:AnswerOur MX500 series will work with cordless phones that have a standard 2.5 mm connection, so this would be a good solution for that scenario since those cordless phones usually allow you to manage your calls even when you are away from their base.
If you want to ensure your phone is compatible with this headset we recommend that you confirm this through our compatibility guide: http://www.plantronics.com/us/compatibility-guide/
A:AnswerMost cordless phones have a standard 2.5mm headset port. If your phone has that port as well then this MX500C headset will be compatible with it.
A:Answerthis has a single cord and you will need a "3" into "2" adapter in order to plug in. These are meant to be used on cordless office phones. they are VERY comfortable. I don't even feel them in unless I accidentally snag the cord as i am walking around. That shouldn't be an issue for you if they are not going to be mobile.
A:AnswerYes. It plugs into any standard "2" jack. You will need an adapter if you want to use for Cellphones or computers. The adapters are cheap and easy to locate. I, personally use mycablemart but anyplace has them, usually online if no where else.
