Problem: I have a few wireless Plantronics CS70N and CS70 bases but the headsets are no longer working. Is there a replacement battery for the headsets or a replacement headset for the CS70? If you offer a replacement for either of these, how much do they cost?

Solution: Unfortunately, Plantronics chose not to use a replaceable battery in either of the CS70 or CS70N headsets. So after the life of the battery dies, the headset is no longer of any use to you. I know it seems like a waste but that is the way Plantronics designed the headsets.

Plantronics no longer manufactures the CS70 or a replacement headset for that system but you can use the replacement headset for the Plantronics CS70N, part number 27910-01, on your CS70.  This is a noise canceling headset; it will get rid of a big percentage of your back ground noise, unlike the CS70 headset which is a voice tube model. It is the same wearing style that you use with the CS70.

The Plantronics CS70N replacement headset sells for $179. Headset Directs offers a 60 day money back guarantee on all the Plantronics wireless replacement headsets. Just remember that you will need to pair your replacement headset to the CS70 base.  Our web page offers instructions and pictures on how to pair the base and headset. If you think the price on the replacement headset is too expensive, you can purchase a new CS70N starting at $240. If you need additional help, please don’t hesitate to give us a call at 800-914-7996.

The bottom of the base will have a white sticker starting with “B” for base.  This is followed by a letter representing the Month (A=January, B=February…) and a number representing the Year (05=2005).

I need a headset for work that will do the following -

1) Plug into a Cisco VOIP phone (the standard one you see everywhere)
2) Greatly amplify volume (so for example, if the call is very hard to hear even with phone’s volume blasting, headset would further amplify sound)
3) Has a mute button on board the headset
4) Cordless would rock but could live without it.

Answer:  If you have any of the 7940, 7960 or 7970 model Cisco phones, you can use just about any of the Plantronics wireless systems such as the CS55, CS70N, CS351N, CS361N, etc.  These wireless systems have a button for adjusting your listening volume and a mute button right on the the actual headset.  The wireless headset charger / base amplifier has independent controls for both your incoming and outgoing volume.
