As you can see in my attached pictures, the lock is a Security Level 5 lock with only a 4 foot cable. Die Hörer sind sehr leicht, das Material angenehm, fühlt sich weich an, obwohl es hart ist. So when I received all the ear buds I tried these first. Great trainers, I bought 4. My sister loved her case! I can tell this will come in handy while trying to lock up my bike in a downpour of rain. I bought them for my holidays because the beach is rocky so fingers crossed i dont get damaged feet Im using the 1. I primarily use the ear controls to increase our decrease the volume, to stop the music, or to dim the sound when I want to hear someone speaking (an amazing feature). I usually wear an 8-1/2 in shoes but ordered a 9 to be sure of sizing.
