Well… I love my Yurbuds Inspire Duro. But after a while they started to have some problems with the enhancers falling off the earphones. It happend more and more and I was afraid of loosing them. It was not that the looked damaged or worn out. But it turned out that they werte just filled with grease and oil from my skin.
If you remove the enhancers from the earphone and was everything with warm mild soap, then the silicone again will stick to the earphone and you wont loose your Yurbuds that easy. Though in my experience they wont be as sticky as new ones.
On a side note, if you do not yet own a pair of Yurbuds, they have started producing new models with a better design to the enhancers. But as far as I am aware, then they don’t design enhancers that fit all the different shapes of ears as they do with the old Duro models… A bit wierd I think?
