Not a quality item.
Vendor got it packaged and delivered fast. It arrived in perfect condition. Good marks for the vendor.Unfortunately, that's where the good ended. Parts of the audio are very muted, to the point that they are not detectable over other sounds through this extension, and others, while still muted somewhat, are at least clear. I tried this on several different devices/ear pieces, with multiple audio settings on each, and had the same issue with all. If i pull out the headphone jack and place the tip against the inside wall of the extensions input then i get the sounds that i usually cannot hear loudly in one ear, and the sounds that i can usually hear are gone. I've tried adjusting the depth of insertion since that has helped before with headphones and the like in the past, but there is no combination of anything that i have tried to get good, clear sound. Not a good quality item, at least not the one i received.
