Here is the email conversation I had with Etymotic when I enquired about a new cable. It's not quite as simple as ordering a cable and have them send one, when you read below you will understand.
I was wanting to buy an Etymotic ER4S cable from you. I am located in Australia and need a replacement cable. I was wondering how much this would cost with shipping.
Look forward to your reply.
Hello Awesome person
Thank you for writing. Unfortunately, we do not sell replacement cables for the ER-4 as an accessory. We require that the earphones be sent to our facility referencing a return authorization (RMA) number. There are a few reasons for this:
1) This allows us to completely evaluate the unit (cable and speakers).
2) There is a small component in the cable design that can easily break if the cable is not properly removed.
3) When our Service Department replaces a cable or transducers, they will perform the appropriate testing to ensure that the earphones perform with specification.
Simply complete the Service Return Form found at http://www.etymotic.com/cs/er4service.html, as this will serve as your return authorization. Print the completed form and include it with your headset inside a padded envelope or small box. Please send only the headset, as we will not require any packaging or accessories. You may use the carrier of your choice, however we always recommend a method that might allow you to track or confirm receipt. The address is listed below:
Etymotic Research, Inc.
Attn: Service Dept.
61 Martin Lane
Elk Grove Village, IL 60007
I usually ask to allow 3-5 days for turnaround. We will contact you with the results of the evaluation and recommend service as soon as the evaluation is complete.
Did Ety support actually say "Hello Awesome Person" or are you just editing yourself out? If they said that, their stock just went up a point in my book.
