Where oh where to buy my helmet?

JPT, I now this is not the time to talk about expensive bike riding gear, but if you want earpieces, the crême de la crême is the Bose QC20 in-ear noise cancelling headphones. They are simply superb: excellent ear plugs if you simply want quiet or earphones if you want to listen to music or podcasts or anything else at a sensible volume.

I saw once that Sony also sells a similar product, but I've not seen or tried it. There are other solutions involving earphones and custon fitted putty that others have spoken well of.
