According to meteorologicals conditions I haven't tested this apparatus in real conditions, only in an aircraft on parking.
In such conditions it work correctly.
A little problem : The switch for active loise reduction is very sensible, I found it on ON position several times after carrying.
Do Not Expect to experience the same performance of the most acclaimed 1100€ pair of headset ( not mentioned on purpose here) ...
But I can tell you the truth: the sound suppression in PNR is definitely working better than average headset on market at same price, with a very soft and sealing ear-cups. When activating the ANR most of the low frequency background disappeared immediately, I cannot say the same in relation to HI Freq background which will be still present. If you connect yours mobile phone the calls are clear both in reception and transmission. But if you listen to music and use ANR, all low bass freq. will disappear giving the sound a metallic feelings. I admit to be an old pilot and my hearing is going to fade a little, so I always had to set my previous headset to a max volume to be able to hear, but the volume of this new product is so strong that I had to set it to a middle value. KUDOS
In summary this Product value is definitely worthing the price, if you compare performances ( almost 70% of the most acclaimed model in benchmark) and price ( only 30% of the famous headset).
I just wanted to try it as a spare device for my passenger, but I will buy a second set for myself.
I was going to purchase a Bose A20 for my wife as I use Bose A20, but I was introduced to this headset. It has noise cancelling and also an input if you want to listen to music.
As my wife is the passenger and does not fly with me all the time I am glad I bought this more cost-effective headset, then spending all the money on a Bose which she would use now and then.
She says they are very lightweight, clear and she can hear everything that is going on.
I would recommend to anyone who does not want to spend the price tag on a Bose or David Clark.
Purchased these as a spare set to go alongside my Bose A20 (which I love) but couldn't warrant spending another £1000 for a spare/occasional use headset.
Have to say I am massively impressed with the AS2!! At a third of the price of my Bose A20, they are comparable in noise reduction performance and sound quality and are actually significantly lighter in weight.
I now find myself rotating between the two as they both offer a different fit and feel which is great to mix up.
