After a few weeks of wearing my custom top and earpiece I have grown to enjoy it more and more each day. Overall, it is extremely comfortable to wear for extended periods of time, the audio quality is unmatched when it comes to phones or radio traffic. We utilize the Plantronics wireless transceivers, zetron phone system from mercury systems and the Motorola mcc5500 radio system. With previous headsets I have had callers say it is hard to hear or understand what I am saying and that it sounds like I am far away. This is not the case with my new custom top and custom molded earpiece. I no longer have to yell into the phone and all my units on the street can hear me clearly. It did take a little bit of getting used to wearing, but with the recommendation of going a few hours at a time until I got completely adjusted to wearing the new earpiece really helped. Now I find myself going 16 hours wearing my headset with only taking it off to go to the bathroom or take my lunch break and find I no longer have the fatigue I used to get from a headset constantly pressing against my ear. I have also noticed I no longer get the headaches I used to get after wearing a headset for 16 hours at a time with prescription glasses on. I highly recommend this Custom top and earpiece to anyone getting started in the field or any veteran that has used the on the ear headset for decades.
