No sound when coming from the headset


Check the compatibility setting on the left side of the Plantronics CS70 base, number "1" should be in the 3 O'clock position. Also check the cable connections, unplug and re-plug the cables. If the headset is dead, then the internal battery may be worn out and it may need to be replaced. The headset replacement model is 72910-01. Below is a link for the user guide to help with the compatibility settings and adjustments, as well as a link to the newer Plantronics headset that replaced the CS70.

I now have 2 Voyager Pro+ wireless ear pieces that have quit working within 2 months of activation. No LED light at all when hitting the on/off switch, when power is plugged in no LED on one, I get an LED...


If the units were just purchased I would suggest having them replaced by Plantronics. The Voyager Pro+ has a one year warranty through Plantronics. The link below is for Plantronics online replacement form.

My headset will not hold the charge very long - is there a fix for this - is there a battery somewhere on this unit that can be replaced?


Unfortunately, the Plantronics Voyager 510 Bluetooth headset does not have a replaceable battery, it is "hard wired". However the 510 headset does have a one year warranty, so Plantronics will replace it within the warranty period. If it's out of warranty, you can buy a replacement if you'd like or buy the newer version which is the Plantronics Voyager Pro+, which is just a newer, slimmer model and it also has newer technology (for the same cost). Here are the links below.

Plantronics 520 headset not working


You do not say what is not working. So on my guess is the headset may be old, and you need to replace it. It needs to be re-paired to headset. It does not hold a charge. It could be replaced with an Plantronics M100.

The handset lifter works, but no sound can be heard or received by either party


If you have a 510a base, then purchased a Plantronics Voyager Pro headset to replace your old headset, it won't work. Those are two different headsets. The Voyager Pro is not meant to work with the 510a base. The correct headset is this:

I Have a Plantronics CS70 and it is not charging correctly or holding a charge. What can I do?


The battery is probably dying, if this is an old unit. Unfortunately the battery in the headset is not replaceable, but you can buy a replacement headset to work with the base unit. Here is a link where you can buy the replacement headset:

Headset doesnt turn on, no red light while charging?


It is possible that the internal battery in the Plantronics Explorer 320 is just worn out, it is an older headset and has been out there for years. The Plantronics M20 would be a good replacement to check out.

Re; Plantroncs 330 headset. Seems to lose charge


Unfortunately the Plantronics Explorer 330 is an older Bluetooth headset and the internal battery is probably just wearing out. Take a look at the Plantronics M20 (see link below), it would be a good replacement headset.
