The instructions are kinda basic, and mine said you only had to press the button on the dongle to get it to connect, but i had to hold mine down to get it to work. Cercavo una cuffia che fosse il non plus ultra per il segmento delle On-ear chiuse e le Amperior vista la loro bassa impedenza e le recensioni più che positive quasi ovunque mi sembravano quelle giuste. I wear a 7 in Crocs. I?m trying to get in touch with Keen to see if they will send me a pair of replacement boots. Super-bummed since I cant return them now. I will be buying only from the official Birkenstock website. I wish these came in half sizes because an 8 is a little large but I was afraid 7 would be to small. This watch case is great, I looked for one for days, scouring review a free review. No luck. Other shoes Ive had in the past were sort of baggy around the toes but these look great.
