However as Jhieminga says I hardly ever touch them once they are set.
(I don't think it can technically be called stereo since we use only one sound channel split in two. I found out when I flew recently with a tank commander the army pipes radio 1 though the left hand headset and radio 2 through the right - that's stereo and very confusing it must be... If civil aviation ever goes over to this system you will need a stereo headset with two volumes. It also accounts for the fact that when you flip the switch to stereo one of the speakers cuts out, which has baffled me for 20 years.... )
I would stick with the more advanced product - but its your choice.
I finally decided to take the mono model: I find myself using the knob on the phone often when I fly and I feel that having a single knob will simplify things.
The price and the quality between the two models seem to be equivalent.
Thanks to everybody for the advices.
