Introduction

Follow this guide to replace a worn-out or dead battery in your Logitech Zone 301 headset. The battery resides within the right ear cup.

It’s natural for batteries to lose capacity as they age. If your headset dies quickly and doesn't hold a charge, it may be time to replace the battery.

For safety, perform this repair when your battery is below 15% charge. Any charged lithium-ion battery can be hazardous if punctured or damaged. If your battery looks puffy or swollen, take appropriate precautions.

Insert the point of an opening pick into the seam between the speaker plate and ear cup.
Slide the pick along the seam to release the four speaker plate clips.

Edit

Step 4

Don't try to fully remove the speaker plate, as a wire connects it to the ear cup.
Use your fingers to move the speaker plate towards the right side of the ear cup so you can access the screws.

Edit

Step 5 Separate the speaker housing

This step reattaches the speaker plate temporarily to keep it from wobbling during repairs.
Align the speaker plate to the speaker housing and squeeze firmly to engage two of the four clips.

Edit

Step 7

Use your fingers to grab the speaker housing from the back.
Pull firmly to pop the housing off from its ball joint.
Be careful not to pull more than 1 cm apart—a speaker wire still connects the housing and the ear cup.

At this point, you'll need to separate the speaker plate you partially reattached earlier to reinstall the pancake screw.
Use your fingers to unclip the speaker plate from the housing.

Edit

Step 21

Align the speaker housing to the midplate such that the speaker wire threads through both parts without twisting.
Align the foam piece so that it's centered around the ball joint.

Edit

Step 22

Align the ball joint to the speaker housing's center cutout.
Use your fingers to firmly press the speaker housing onto the ball joint to pop it back in place.

Edit

Step 23

Installing the ear pad can be tricky. Be patient and work slowly—it may take a couple tries.
With one hand, firmly hold an ear cup steady.
With your free hand, place the pad over the top of the cup, so the fabric flap slips over the cup's plastic lip.

Edit

Step 27

Thread the rest of the flap over the lip, working your way around the entire cup. Gently stretch the pad as necessary.
Check the entire perimeter of the cup to make sure the ear pad is fully on. If any of the fabric flap is sticking out, try to push it over the lip or remove the ear pad and try again.
