Ordering

How to order

  1. Pick a cable from the list below.
  2. Under Headphone connection, choose the option for your model.
  3. Choose the player plug that matches the output you use most; see choosing the player plug.
  4. Not sure which socket your earphone has? Send us the model and a close photo of the socket before you order.

Before you order

Check your earphone

  • Check the model name printed on the earpiece or box. IE 40 PRO and IE 500 PRO look alike from the front but use different connectors.
  • IE 80 and IE 80 S each have their own Sennheiser replacement cable. Tell us which one you have if you are unsure.

Questions

Common questions

Will an MMCX cable fit my IE 40 PRO?

No. The IE 40 PRO socket has an extra sheath; choose the Sennheiser IE40 Pro option.

Is the IE 80 cable the same as the IE 8?

Our configurator lists one Sennheiser IE8/80 option. A forum owner reports the IE 80 and IE 8 cables differ, so tell us your exact model when ordering.
