Weve tried a variety of charging docks. My size 13 foot felt like I was trying to slide it into a 10 or an 11. I made several recordings using the G2 headset on my phone, First test was using a overhead fan on high about four foot over head both on and off. I bought these as a Christmas gift for may grandson. JBL if youre listening i am not happy customer. These are great as long as you wear heavy gloves when you pull your shoes in and out. And, just as importantly, they are totally comfortable. It is really a perfect example of the best of cozy mysteries. I have since ordered a second 20 feet, works great in my shop dust collection. Reception isn?t that bad either.
