Logitech G930 with Cisco 7960 series IP phone

post #1 of 6
Thread Starter 
I have a set of headphones that I happen to enjoy quite a bit. The logitech G930 are wireless RF 2.4ghz headphones with included microphone. I will attach a link to the headset below.

This headset does have flaws but being as I am not an audiophile but am an avid cord ripper, these are great. Replacing $120 dollar headsets via chair -> cord -> rip, isn't fun. Granted I finally got around to buying a soldering iron and have 4 pair of headsets waiting for a fix, we might see the household outfitted with gaming headsets who knows. I digress.

I want to know what the possibility is to get this RF wireless headset capable of being used with a Cisco 7960 IP phone. The headset uses a docking station which houses a usb reciever and has a spindle of wire around it that houses the charging micro usb cord. It all goes to computer using a single usb cord and if you don't mind loosing the spindle charger you can plug the usb reciever directly into a usb port for the same headset functionality.

The Cisco phone uses quick connect cable to attach a headset to the back panel of the phone *which I believe is Rj9 port*. I had looked at several different adapters, such as a usb to rj9 adapter and attach a female to female adapter. I have not purchased the 2 adapters as of yet, as I had not figured out if the headset would even work.

I do not have a complex understanding of audio formats or the difference between what this headset handles and what the cisco phone is capable of using. If I concoct an adapter daisy chain, would this headset carry both voice and sound? Really would like to use these ear enclosing comfy beasts rather than the one ear plantronic base model headset I use at work now.

My understanding of mono and stereo, or lack there of, might deter potential responders. Please understand I do not know exactly what I am doing or the complexity of hooking a mono IP phone to a stereo headset and if this will even function. Just need some input on if me purchasing multiple adapters to Frankenstein my headset to this cisco phone would produce sound/voice and function.

No, USB is a serial, bidirectional data bus.
The signals going to a speaker and from a microphone are analog.

I apologize in advance as I don't mean to sound ignorant to the answer. I am having a hard time understanding how that translates into a yes/no answer. Given that daisy chaining adapters was only the primitive method I had conceived. Understanding that I have very little experience when dealing with audio related issues such as this, I would hope that there would be a solution regardless of if it matched what I thought of.

I do not understand the difference between a serial, bi-directional data bus in reference to why it would not function when connected to a cisco phone. I am at a huge disadvantage even attempting to discuss what I assume is how things work as I feel it will swiftly be refuted. The sound from my mic to my headset speakers is analog or the sound input from my mic to the phones speaker is analog? The conversion from analog to digital occurs on the computer the usb is connected to, so being that the phone uses a connection that doesn't utilize bi-directional data transfer it wouldn't be possible?

Think I might be in outer space with this one, please don't rip apart my limited understanding in a negative way. I am attempting to understand what *The signals going to a speaker and from a microphone are analog* means. So my speech is analog waveform input that is converted into digital signal just as incoming audio was analog, converted into a digital signal and is converted back into an analog signal before playback on my speakers. My analog signal coming from my mic would lack the ability to be converted using daisy chain adapters into a cisco phone using RJ-9. Or the other question and one that I had assumed was correct being that the use of usb for my headset forces my headset and its internal components to convert the audio from digital to analog during input/output. If that is right though, why would my cisco phone lack the ability to receive both incoming and outgoing sound and forward/receive that from my headset given it does the conversion regardless of if a computer is attached? Is the inherit problem the inability of my Cisco phone to receive an analog signal?

My understanding of it is very limited and I do know that. I can picture a horde of people anticipating an uneducated response to pounce on me and rip my head off. Please be understanding to my lack of information as if I didn't give a **** about an answer further than a *yes or no* I would eat what you have said and let the post die. I really would like either a direction for continued research localized to what I am asking or a detailed explanation by yourself or another forum member.

*edit* Seeing a few quick connect adapters that centralized around usb to rj9 modular connections can I assume it is possible to connect a headset designed to replace a handset to a computer using such an adapter. Assuming that the adapter would be replacing the need for an IP phone in a work at home type environment and allow use of a soft phone while retaining the handset/headset replacement. If it is possible in this direction, the lack of ability in the opposite direction is my primary concern.

As far as I can tell, there is no USB connector on the Cisco phone.

USB is a digital bus designed to carry digital information.

The signals on the "Rj9" are analog. They're voltages that represent the pressure waves hitting the mic diaphragm.
Simply connecting a digital signal to an analog device with a passive adaptor won't work.

I had thought that the headset I am using *logitech G930* was under the same design principles other USB headsets where. Given that a usb headset had to convert back and forth digital to analog within the headset it's self as it did not deal directly with a sound card. My readings imply otherwise for non usb headsets but again my understanding is so vague it is likely I am talking out of my ass.

If the difference between the two is native support for completely different formats than it would be a challenge for the astute, not to mention those on the lower levels of understanding such as my self . Would you mind describing a way one might achieve a link between a device that utilizes a digital signal to one using an analog signal regardless of how unfeasible it might be? Just from a curiosity stand point so I can understand how far off my idea was. Just saved a bunch of money on adapters by switching to AVS, high brow humor.
