Aukey makes smartphone cables, chargers, battery packs, etc. I’ve tried quite a few things made by Aukey (some were sent for review and others I bought) and have always been happy with the quality. The bluetooth sports headphones made by Aukey are no exception (I bought them). The run about 4 hours on a charge and sound fine for my purposes (90% podcasts and audiobooks, 10% music). Most importantly, they are comfortable, unlike so many earphones I have tried. They are regularly $(removed), but you can get them for a limited time with the coupon code: 2CHBUTGF.
