I wear them sometimes for work and I?m on my feet a lot! Soak your unit for 4-6 hours and then rinse- the contacts are as good as new! I bought these to go with my outfit for a wedding evening party, reasoning that (1) they?re black so will go with what I?m wearing, (2) are fairly unobtrusive, (3) it?ll be dark and/or strobe-y so people won?t really notice that they?re crocs, and finally (4) who?s going to pay any attention to my feet when there?s a beautiful bride and beaming groom to look at instead?! My old headset was the wired Plantronics Rig with the Mixer and I used it for about 4 years. I wish there was a couple more. For a warm day, they?re a blast. It takes about 10-12 hours to fully charge depending on how depleted the battery is, but Anker does have a model with a faster charger. It was easy to put together and is sturdy enough to hold both our electric bikes and roll around smoothly without any concern of tipping over. These are a pearlized pale pink color. I gave them to my wife.
