Headphones not working with Honor 7 Lite

[Demonimo]

My headphones, wich are for my xbox one, used to work on my phone before the new EMUI 5.0 upgrade. After the upgrade, it doesen't connect to my phone, but they are not broken, I have used them on my xbox. The weird thing is, thar I have another set of xbox headphones, but they are connected to the xbox with a stick. They are connected to my phone with a removable cable. The headphones need recharge if it is important. I think the problem is within the new upgrade on my phone, but I don't know how to fix it. If someone knows what to do, please reply.
