I have a wireless headset Sennheiser very good reception with 200 m for several years (10 years) but were too damaged studding, I told myself that I would never succeed in finding and then I got nothing ventured, nothing gained I'll take a walk at Amazon and there I found the first time and in addition this is the exact replica of my original archi waste studding result my helmet at the much newer air 3-4 years knowing that I had taken the premium at the time. This is a purchase that I recommend. I forgot this is the model I own HDR 120 for HDR110 I can not judge the perfect compatibility. I even think I'll order another pair to have in reserve.
