They are easily 1/2 to a full size too small! I just plugged the USB cable into my port and the headphones paired right up. Llevo ocupándolo unas pocas semanas y no he tenido ningún problema. The good quality flat cable appears to be tangle free but thinner than Boat Bassheads 225. Things began to unravel during assembly, parts were super cheap, particle board had cracks on the underside, and on the decorative particle-paper molding the paper-thin veneer was already cracked and peeling. But this was resolved by tightening the hex screw in the handle. It?s that noise INSIDE the air chamber that the noise cancellation circuit cancels out (by producing the opposite noise). Glad I didnt return them! PROS: Sound quality is fantastic. First time out, I purchased one of the "clear pouch" type holders for my iPhone 8 and was instantly disappointed -- felt like Id just slipped it into a random ziploc bag and the arm band with extension was either too tight, or too loose -- just plain short-sighted and not user-friendly.
