I have a pair of the Cruising Solutions headsets and the radios work reasonably well but the earphones have flat foam surfaces that do not go around the ears and this, coupled with the relatively weak clamping force of the plastic bridge over the head
, results in the earphones slipping off your head and ears e.g. when tilted back looking up at the person up the mast
wearing the other set. Proper, formed earphone pads that go around the ear to locate the phones would improve the product 100%. Suggest you check this before you buy on line.
