PACK OF 2 FBI Style Black Twist On Replacement Acoustic Tube for Earpiece Headsets by MaximalPower

could this wire easily be spliced into a 3.5mm end?

Are these compatible with titan radio surveillance kit trsk & tr4sk?

Is this for right of left ear? They always say universal but that isn’t true since they’re bent for either the left or right side. Thanks

what is the best kind of radio to use for this ?
