These will make it safer to ride with earphones. I tried some on Sunday, they are really great, you can hear all around you, your music and they are really comfortable.
Does anyone have them? They are not cheap, but can be had for around £40 with a bit of shopping about.[/QUOTE]
I have some and they are excellent however I only get to use them occasionally. For city riding I rely on my ears too much for any extra distractions. I don't mind using them on quieter country rides where visibility is good and traffic is (very) light but that's about it.
In built up areas, particularly during the day, I'll often hear a vehicle at a junction before I get a clear sight line, it's saved me more than once when some fool has not bothered to look properly before crossing/joining a road I'm on.
