Overall The Extenders Work And Are Comfortable.
I bought these lightweight rubber extenders from Best Tim Digital and fulfilled by Amazon for about $4 for (4) extenders.<br /><br />Overall, they do work.  You will have to fumble a bit to get the ear loops around the rubber nubs so it feels a bit awkward.  However, once you get it on to your proper fit, it feels just fine.
