The box does have a chart that gives you a rough indicator of the charge status, but it wont give you highly accurate readout. UPDATE: The box these go in so they can charge is no longer charging itself. I wouldve preferred a more bluish camo color (to match my PS4 controller haha) but nevertheless it still matches nicely. These sounded fine when used from my phone, but I need to use them with my laptop as well. Waiting for new colours as my size seems to be unavailable out everywhere. A smart feature is having both size jacks! Honest review with my new Certified Refurbished mouse Ive received:NEW review (8-30-17)After a day later, the scroll wheel stopped working and I did all I could to troubleshoot the mouse with plugging into a different port/computer and blowing canned air. This normally happens around noon. Now I dont know about you, but I handle my drives very carefully, and I followed all of their instructions. I would like to update this negative review.
