Introduction

The Plantronics Voyager Legend is a Bluetooth headset, with user-friendly features such as extended battery life and an easy-to-use magnetic charging port. Because of these features, power problems can be handled accordingly, to ensure a longer life for the device. This guide will detail how to carefully disassemble the main unit, remove the internal power circuitry, remove and replace the battery, and reassemble the unit for the prolonged life desired.

Remove the soft, protective, outer covering. Use a heat gun (or a hair-dryer) to heat the main unit of the Plantronics Voyager Legend.  This will loosen the adhesive that bonds the covering to the housing. Use the pointed end of a small, metal Spudger to begin separating the covering from the housing.

  • Use the pointed end of a small, metal Spudger to begin separating the covering from the housing.

  • Rotate the Spudger to the rounded, dull end and gently detach the rest of the covering.

  • It may be necessary to reheat the unit to keep the adhesive soft enough to remove the covering without damaging it.

Begin removal of battery circuitry. Use the flat end of a Spudger to begin lift against the metal tab of the top edge of the circuit board unit. When lifted enough, use the pointed end of the Spudger to lift the remaining distance.  This is accomplished by inserting the pointed end of the Spudger into the hole in the circuit board unit located at the opposite end of the charging port.

How to put it back again ? and is it gonna be how it used to be ? with the rubber being torn apart ??

1. I dont really think you need to remove the rubber. It gets stretched and torn and doesn't go back the same even with adhesive. I think the black plastic "cap" can be removed without fully removing the rubber. Other than that the repair worked ok, but it doesn't look/feel the same so I ended up buying another one anyway and now this is my spare. It's a fairly delicate/complex operation and probably not worth the effort.
