Excellent Setup Ruined by Humming Noise

[IceNine]

I'm at a point of extreme frustration now and hope only to find an answer to my issues. Recently, I purchased a pair of Sennheiser HD 7 DJs, A modmic 5.0 and a Behringer Xeynx 302USB in hopes of getting excellent audio, great mic capture, and a decently loud active sidetone as a cherry on top. At first, this set up seemed great. Powering the mixer off of the wall and bypassing its DAC properties provided the best experience. However, when the mic monitor is turned up, there is a noticeable hum in the background. I have already made an extensive post about this issue which has received some views but has not yet lead me to the answer I seek. I type this message now to state how terrible the situation has grown to. I failed to mention in my post that I use a wireless mouse which when plugged in to charge then held in hand produces an UNBEARABLE amount of this AC hum! That noise, complimented by the keyboards noise causes the situation to be so horrible that I would rather mute the microphone and avoid friends rather than try to bear the horrible hum to speak with them. At this point, Money is now longer a factor. I'm looking for anything to make this setup work. I do wish to try to get the solution to follow a few criteria.

1. The headphones receive sound from both the PC and the Mic so I can hear myself as well as in game audio.

2. The PC must receive audio from the Mic and not loop the PC audio back to itself

3. I would prefer if the Mic was discrete like the ModMic 5.0 and does not extend over my keyboard or hover above the set up like a stand alone XLR microphone.

 

I have looked into replacing the mixer with one like the ProFX4v2 but I am unsure if this mixer can stop the PC audio from looping back to itself. Any response or help will be appreciated. Thank You!

You shouldn't be posting the same thing twice, try and bump your original post.

I feel the premise of this post (Searching for entirely new hardware to solve the issue) is a large enough update to warrant its own post. The posts are roughly a week apart or more. If you think otherwise, ill take this down. Thank you for your reply and good day.

Background noise cancellation / reduction for the mic? 

 

Otherwise just get a better mic, or don't have it play back to you? (Edit: sorry you probably mean recording wise?)

I don't know what hardware I would use for noise cancellation. Since the monitoring must be 0 delay, it cannot be passed through software first. Not having it play back would not be a solution. If you have other microphone suggestions that you feel would fit the criteria or close to it, I am willing to hear them.

The Hum occurs in Recording as well as live monitoring. correcting it in post is a solution for the long term as far as creation and not user experience but the experience of the set up doesn't feel very good at all when the hum is consistently occurring when not recording.
