What IV835 is deficient of is comfort of wearing – it simply lacks any. Though one may think the easy (supposed to be convenient) putting on is a plus – it will make you think of taking it off your face as soon as you have hung it there – it is just a nuisance. We find the lack of sound control buttons to be peculiar in a situation where the only remaining button – the multi function one – is inconvenient and hard to use.
