Introduction
The microphone assembly is easily distinguished by its "boom-like" shape. The actual assembly is comprised of a voice-tube, and a circuit board system. The microphone replacement guide will detail how to carefully disassemble the microphone unit, and remove and replace the different components that comprise it.
-
-
Loosen snaps that hold the assembly together.
-
Use the pointed end of a small, metal spudger to begin separation of the snaps, at the end of the unit.
-
After initial separation, use the flat end of a plastic spudger to continue loosening the snaps, by following along the circumference of the microphone unit.
-
-
-
Locate the volume button at the rear of the microphone assembly, near the earpiece assembly.
-
Use precision tweezers to lift the volume button out of place and remove it.
-
-
-
Remove the voice-tube.
-
Insert the pointed end of a plastic ppudger to lift the voice-tube out of position.
-
Disconnect the leads that attach to the voice-tube.
-
-
-
Remove the circuit board.
-
Use the pointed-end of a plastic spudger to begin lifting the circuit board out of place. Begin at the end nearest the voice-tube location.
-
Use the flat-end of a plastic spudger to continue lifting the circuit board out of position.
-
-
-
Access the leads that connect the circuitry.
-
Use the spudger to make sure the circuit board is completely free.
-
Expose the leads so they can be disconnected.
-
-
-
Install a new circuit board.
-
Disconnect the leads using a pair of wire cutters. Scissors will work if no wire cutters are available.
-
Solder the leads into the correct location on the new circuit board.
-
To reassemble your device, follow these instructions in reverse order.

Where do I locate the parts for the Plantronics Bluetooth hardware?
You can not get the parts.. At least not on Ebay, Amazon and just about any other place that I searched.. Maybe Alibaba if you want to take the chance of having your credit card or any other form of payment jacked.. This fix is a joke due to the size of the components and wires that need to be soldered.. If only the "Voice tube" or cone shaped thing inside of the plastic tube is bad they its ok.. I will mention though that this type wire is coated which is why you can have the two "bare" wires touching and not have a short.. You must but this off in order to be able to solder first.. Burn too much and you will have crispy wires not worth crap.. I know this because I have pick up more than a few sets up beats head phones on Ebay for 20-30 and fixed.. You can pick this headset up on Ebay on the dirt cheap now that the new one is out, its not worth the hassle to fix or attempt to fix and it is misleading in the sense that it makes it seam like a no big deal kind of thing..
I used this repair guide to take it apart and clean the mike and board and now people can hear me a lot better.

How did you clean it
This set of instructions does not work. I am unable to separate my mic boom past the point indicated in the third photo of Step 1. After much careful prying, I reached a point where my only option is to apply a lot of force to pull the halves of the boom apart. Even then, the rotary section of the boom where it meets the main housing, refuses to separate. Something is amiss in these instructions, there is a step missing that should explain how to get the rotary housing opened up.

Update: on my Voyager Legend the solution was to follow this other iFixit guide to gain access to the speaker, and remove three small screws that hold the boom to the rotary assembly. Only then can the boom come apart at its base. Plantronics Voyager Legend Earpiece Replacement
