Purity is a small business that specializes in tech products and accessories. 

Promising review: “I’ve tried soooo many different types of ear buds over the years with no success. But these Purity open air headphones are the first pair I’ve ever tried that actually fit well, don’t hurt, and sound great! So, after many years of trying, I’ve FINALLY found the right ones for my ears!! Woohoo! They are comfortable, lightweight, have great sound clarity, are easy to operate, have great battery life, and people can hear me clearly when I talk on the phone with them.  I definitely recommend these, especially if regular in-ear buds don’t work for you either.” —CPic
