PowerUp! Sound Wave Wireless Earbuds

Got a pair of PowerUp! wireless earbuds here, still in the box. One black and one white. These are the Sound Wave model. They're universal so they should work with pretty much any smartphone or bluetooth device. Box says they get about 3 hours of playtime and have a built-in mic for handsfree calls. Pretty basic but gets the job done if you need some cheap buds for the gym or whatever. $9 obo
