I really really like these. I have two one in my truck one in my car I like it because I can put my headphones in while it’s being charged so I can talk on long drives like four hour drives and the battery never goes dead and I have the ability to utilize the plug-in. I don’t like Wi-Fi. I have a tendency to lose them so I like old-fashioned wire it just is my preference.
