You do realise that it's against the law to wear headphones (in/on both ears) whilst driving, that goes for cycling as well (on the ROAD).
You can only have one earphone, otherwise in the eyes of the law you are restricting your aural perception of your surroundings!
I was lucky last year as the police just told me to remove one earphone and didn't fine me £50.
In my view it's completely Bonkers as you can have an ICE in a nicely soundproofed vehicle playing loud enough that you can't hear much of anything outside.
"yes I am aware there is a restriction on the max decibels you are allowed". But it still restricts your hearing of most things outside of the vehicle.
The daft thing is you can still drive if you are completely DEAF!
P.S.
The bone conducting in-ear phones give the least wind noise and if you have them positioned correctly give good sound quality.
As stated earlier in the thread I also don't mind paying a little more for something that works.
Buy cheap, buy twice.
It is very definitely not illegal to wear both headphones on whilst driving or cycling in the UK. You can potentially be fined for driving whilst wearing headphones if the Police consider you to have been distracted whilst driving, but there the offence is still not about wearing headphones.
