The EZX 60 was recommended because of its wearing comfort, I can only confirm me fit it excellent and got stuck but comfortable.
But a absoultes "no go" is the port for the charger, a completely proptrietäres format, the adapter cable here offered to EUR 40.- is probably an April Fool's joke. Now finally has something of a standard in the ports for mobiles established and again someone is cooking his own soup - simply unacceptable. Have no desire, nor carry around a cable and not likely to have in case of need it. (The "Standard Cable" I lie for your mobile phone always in the car)
That is also the reason for the 2-star rating, as the quality is otherwise perfect.
Could the headset easily convert to a EZX 80, which is even better sound and has a mobile phone standard USB plug, also supplied even a USB cable and a charger for your car and is therefore highly recommended.
With regard to the reported here problems with the breaking earloop I could make no experience, therefore no statement to my part.
