Are these noise cancelling?
My headphones power themselves back on after turning them off. I have tried the recommended resets but it does not fix this problem. They only stay off while being charged. Please help!
Does the cord have a mic? And if my daughter connects the Aux cord to her chromebook will she be able to speak? (she can't connect to her school laptop with bluetooth, so I want to make sure if she plugs these in she will be able to hear and speak)?
I have been using these headphones for a while and I really like them, but after wearing them for a while they start bothering me. I feel like they put pressure on my head/ears. Is there a way to get it loose?
How do I connect to my computer? My iPhone can pair with them but my PC is unable to discover them.
JBL LIVE 400BT I got as a gift and I used twice and they blew out. There is something wrong with the wiring. I am so sad I loved these. Anyway I can get them fixed ?
My google assistant touch surface doesn't work. I can hear when i get notifications on my phone but when i hold the touch surface nothing happens. When i double tap the touch surface, again nothing happens. Are the headphones faulty?
Hi there, are these headphones ctia or Omtp? Many of my headphones are damaged on my Xbox one because I don't have this information.
