I ordered a new Muse from Amazon over the weekend. After unwrapping it, I was surprised to find that the forehead sensors were dirty, as if the product had been previously used (see first photo below). I assumed it was a return that the company repackaged and resold as new, so I requested an exchange via Amazon.
Today, I received my replacement Muse (also sealed in plastic) and found that it too had dirty forehead sensors (see second photo below)!!
Can anyone confirm that the grime visible in the two headbands below should not be present on new units? Any idea of what might be going on? Both of these headbands were sold by Amazon directly, so there is no 3rd party reseller involved.
Thanks for the input!
