Help with ENC, David Clark headset

I recently purchased a David Clark headset H10-13X, it came with Electronic noise cancellation. It has two buttons ON and OFF, Every time it's in the ON position I get a unpleasant buzz on the left side of the ear. When the ENC is off everything works fine. What could be the issue? Is it normal?

I had something like that too, with an early generation DC END headset. I never really did get it working the way I thought it should. I took it to the avionics shop, and they said it was working properly. It hangs on my wall to this day. I did buy a later model DC OneX headset, and it was vastly improved, I really liked that one! Unfortunately it's at the bottom of a lake now

For the ENC headset you have, try moving it around on your head, and switching sides on it, that may help.

Am not an expert on DC products, but a buzz is not normal on any ANR headset.

It sounds faulty. Send it back and get a replacement asap.

PS, I am assuming you are using it in a normal configuration - plugged into a standard aircraft intercom, for which the headset is listed as compatible with? The intercom you are using it with could possibly be faulty, so check it with another ANR headset.

Is there a mono-stereo switch?
You may have it set on stereo with a mono airplane system.

On my H10-13X there is a mono/stereo switch hidden in the battery box below the battery. Mine has never produced any particular buzzing noise, but the ENC system does produce 'anti-noise' that can be perceived as very light 'white noise' depending on how good your hearing is. This should only be noticable if you're in a very quiet environment. If you're using it in an aircraft with the engine running, you should get a very noticable drop in low frequency noise when you switch the ENC on. It should not produce any additional noises.
