My husband has gone through at least 3 headsets a year cause of compatibility, or over use.  He didn't have an issue with motorola headsets at all so we finally got him a phone that was compatible with motorola and he is very happy with the product, great clarity, ease of use, comfortable, just don't purchase via amazon...shipping sucks and they don't stick to what they tell you and expect you to just sit back and forget about the product you purchase.
