" Certain headphones have much broader "virtual stages" than others. The One Con:--the tread has deep, diamond holes of many sizes, and actually catches one perfect fitting rock or pebble inside nearly every hole. As I mentioned before these straps run across both the front and back seats and are either right above your head or touching it. Compared to the Fiil T1X and T1XS, these are smaller and the fits is sooo much better, which is a surprise in itself as they fit well. Super happy with these and highly recommend them! I will most certainly buy this one again when I need more. Da kann man nicht meckern. Each time, its the same issue in that they stop working in one ear. Maybe with enough time and give, they would have fit well enough, but given the two right shoes thing, I never got the chance to find out. I personally feel the target range for wireless headphones is $30-$50.
