I've been using these for a while - they don't seem particularly good at stopping high speed wind noise, and at slow speeds I can't hear pretty much anything - voice, engine, other traffic. Admittedly they are very comfortable, and quite cheap. https://www.amazon.co.uk/gp/product/B0007XJOLG" onclick="window.open(this.href);return false; I was talking to someone a few months ago who said he has ones which only block lower frequencies, and which cost about £70. Anyone know what these are, and tried them? Also, any other recommendations would be appreciated.
