I suspect that is where the problem is. Der Kleber steht am Innenschuh raus und scheuert. Good for long distance, well worth the price. Theyre more forgiving though so thats why I use Large in the ear which is more of a Medium! This is a superior quality product with the latest bells and whistles (Im looking at you, Chroma and Hypershift). I loved the fit and the style. the lack of seal ultimately led to reduced low end response, ear fatigue and what not. stable than it looksCons1. But, unless you are highly mechanically skilled, you will struggle to assemble this thing. More than enough room for a family of 4, 2 bags each person, and doggy supplies.
