some of us aren't up on new trends, what is the wallet card for and how do i use the air vent pc.

They also tossed in a magnetic mount for your car's air vents and a card wallet for your phone (go figure)

They also came with a good quality case; L/M/S Ear tips; Soft Ear tips "like earplugs"; a 3M wallet sticker; and a magnetic phone holder that connects to your cars air vents

It comes with a case for your earbuds, a credit card wallet for your phone, a magnetic phone mount for your car (the kind that plug into the air vents), some wire ties, and the best of all...earplug tips

They were delivered on time and so far I love them as I just

Perfect e so affordable

n’t feel like they will fall out while doing any physical activity

Sound is good , sync easily battery life is good as wellMade well not sure why the bad reviewsDidn’t give 5 stars because I have Bose sport wired headphones and their is a difference but for almost $120 less these are a great deal.
