I stumbled upon these, and knowing Audio Technica?s reputation as a brand, I decided to pick em up. It will come in very handy while travelling I am sure. I was slightly concerned Id experience the screen toht issue, but I was lucky. Its easy to adjust and there are directions as well. This is a great shoe and runs true to size; however they do not accommodate the swelling of my daughter?s feet like the ones Land?s End sold this year. I am blown away. Das Problem: Ersatzstöpsel für die Liberty Neo. They are darker than pictured, but thats what I was hoping for. Maybe a bit expensive for some but at the moment a good buy unlike some jabra elites I bought with 4 mics and active noise cancelling and was very disappointed and they were double the price of these. This will fix the occasional "crackling" problem.
