Product Manuals
Q: Does this headphone power off automatically? is that a feature for power saving ?
A: I dont belive it does. I tested this by using the headset to listen to music while I took a nap. When I woke up an hour later my music was done but the headset was still powered on.
A: I was listening to XM radio when phone rang. Simply pressed button to answer and went to phone. When call ended went back to listening to music
Q: Can these headphone be used in the wired mode? I'm concerned about security.
A: They sure can even have a 2.5mm jack into it with a cable included 2.5mm male to 3.5mm male aux
A: what you'll need is a rca to female headphone adapter and a Bluetooth transmitter. You plug the transmitters headphone jack into the adapter. Make sure the adapter is a rca to female adapter.
A: Yes it’s 100% annoying. I try to turn down the sound because of noise and then the speaker is too soft to understand then I turn it up and the noise is too loud. Absolutely infuriating.
Q: Can I use these via pc while in a call and gaming?
A: Yes you can use
Q: Are the ear pads made of leather?
A: They are made of faux synthetic leather.
A: No it is not. When the manual said the media controls aren't usable, they meant everything. What's also not in the manual is that you also can't use the microphone wired.
