This would allow the plastic to hold the wire in place much like the stock cable does. There is elastic at the buckle for comfortable give. After some searching, I purchased this panasonic headset. Dont know why the description still mentions CL15 but then you can run this at CAS15 at a lower frequency. Would so recommend them for any occasions. Also didnt seem nearly as warm as before. I purchased this as a cheap, temporary solution to protect my new AirPods Pro while waiting for something more permanent from Catalyst or Spigen to become readably available. They aren’t too deep at the toe box but do expand with wear. Again, this is more a matter of taste on my part. Nice sturdy rack, especially for the price.
