Get your MMX300 fully working again
A frayed cable turns a good headset into dead weight. This replacement brings back the mic, the inline control and clean audio at your desk.
A 4-pole plug that carries your mic

A 4-pole plug that carries your mic
The single 4-pole TRRS plug routes both audio and mic signal to the computer or controller input. That is the difference between a headset that only plays sound and one that lets you talk. Seat it fully into the jack and the mic path stays connected.

Volume and mute at your fingertips
The inline control box has a sliding switch and a red indicator stripe, so you adjust volume or mute without reaching for the PC. It sits on the cable where your hand already is, which means fewer trips to the keyboard during a match or a call.

Built with gold-plated contacts
Gold-plated plug contacts sit under a matte rubber-coated cable with strain-relief sleeves at each plug and at the inline box. Those sleeves take the bend at the connector, which is where most cables give out first.

Protect the plugs and the cable lasts longer
- Hold the plug body
Pull from the plug or sleeve, never from the wire, to protect the solder joints.
- Coil it loosely
Loose loops keep the rubber coating from kinking at the same spot.
- Check the sleeves
Look at the strain relief at each plug every few weeks for early fraying.
- Keep it off the chair wheels
Crushed cable is the most common cause of a mic that cuts out.

Questions and answers
It is the replacement for the MMX300 second-generation computer version. The MMX300 line has several cable versions, and the wrong one may not match the inline controls or the mic connection. Confirm your headset is the second-generation computer version before you order.
Yes. The single end is a 4-pole 3.5mm TRRS plug with gold contacts. The other two plugs are 3.5mm, one with a red ring and one with a green ring, for the headphone and microphone connections.
They will, as long as your PC has a jack that combines mic and headphone input. Plug the 4-pole end in and the mic path connects. The sliding switch on the inline box then handles volume and mute from the desk.
A generic 3.5mm extension has no 4-pole wiring, so the mic drops out and there are no inline controls. You pay for matched wiring, gold-plated contacts and a rubber-coated cable that holds up at the plugs. Replacing the cable costs far less than replacing a headset that still works.
Yes, if the phone or controller has a jack that accepts a 4-pole plug with mic input. A 3-pole-only jack will pass audio but no mic signal, so check the input before you plug in.
