Is the 3.5mm auxiliary input jack only on the M-4?
Both the M-4 and the M-2 have auxiliary inputs. However, the Passive muffs do not. Last updated: Tue, Mar 8 2016 3:36 pm EST
Is there an auxiliary input on both head muffs?
Yes, there are inputs on both the left and right head muffs. Last updated: Tue, Mar 8 2016 3:36 pm EST
If you plug the auxiliary cable into only one of the two head muffs, will you be able to hear your music/phone in both?
Unless you have an auxiliary cable with a splitter, you will only hear noise in the head muff that the auxiliary cable is plugged in to. Last updated: Tue, Mar 8 2016 3:37 pm EST
Are the M-Series head muffs Bluetooth compatible?
Even though we would love to someday incorporate Bluetooth capabilities into our head muffs, these M-Series are currently not Bluetooth compatible. Last updated: Tue, Mar 8 2016 3:36 pm EST
How will plugging in an auxiliary cable affect the digital compression of the head muffs?
Using the auxiliary cable will automatically turn off any digital compression or electronic features. Meaning, if you have any electronic device plugged in you will not experience any sound enhancement or electronic sound shut off. This only applies to the head muff that the auxiliary cable is plugged into. For example, if someone was using an auxiliary cable to listen to music in their right ear muff, only the left ear muff would be experiencing sound enhancement and protective sound shut off.

Last Updated At: 04/15/16What is BackerKit?
BackerKit is a service that crowdfunded project creators use to keep track of hundreds to tens of thousands of backers—from shipping details, pledge levels, preferences and quantities, whether they have paid or had their card declined, special notes, and everything in between!
The BackerKit software and support team is independent from the campaign’s project team—BackerKit does not handle the actual reward shipping. For more information about the preparation or delivery status of your rewards, please check the project's updates page.
How does BackerKit work?
After the campaign ends, the project creator will send you an email with a unique link to your survey. You can check out a walkthrough of the process here.
I never received my invitation. How do I complete the survey?
The most common reasons for not receiving a survey email is that you may be checking an email inbox different from the email address you used to sign up with Kickstarter, Indiegogo or Tilt Pro account, or it may be caught in your spam filter.
Confirm that the email address you are searching matches the email address tied to your Kickstarter, Indiegogo, or Tilt Pro account. If that doesn’t work, then try checking your spam, junk or promotions folders. You can also search for "backerkit” in your inbox.
To resend the survey to yourself, visit the project page and input the email address associated with your Kickstarter, Indiegogo or Tilt Pro account.
How do I update my shipping address?
BackerKit allows you to update your shipping address until the shipping addresses are locked by the project creator. To update your address, go back to your BackerKit survey by inputting your email here.
When will my order be shipped, charged or locked?
That is handled directly by the project creator. BackerKit functions independently of the project itself, so we do not have control of their physical shipping timeline. If you want to check on the project’s status, we recommend reading over the project's updates page.
I completed the survey, but haven't received my rewards yet. When will they arrive?
As BackerKit does not actually handle any rewards or shipping, the best way to stay updated on the shipping timeline would be to check out the project's updates page.
