Today 5 mile run and controls wouldnt work within 5 minutes of running. Im not happy at all The plug and the build quality were my reasons for giving less then 5 stars, the plug is large and doesn’t fit any device with a case on it. This is my wifes second pair of the MukLuk Morty Slipper socks. Some of the sponges cracked and broke apart while opening the plastic cellophane they where wrapped in. I bought these to replace the windsocks on my Blue Parrott BT350s and 250s and then the little black thing that they make. Noise cancellation is about the same as the original cushions, and the smaller inner diameter hole actually helps these headphones, since the speakers are only about 40mm in each ear anyway. so this product is an easy buy in my opinion. It fits well in my ear and hangs without an issue. For example, on the 20" wheel mountain bike my youngest rides, I was just able to fit the (thankfully) narrow clamp assembly on the seat post tube while still being able to pedal fully to adjust the gears and lube the chain.
