Reviewer: Josh from Kearney, NE United States  
I work in security and I can hear transmissions really well in all situations.
The customer service is the best I have ever dealt with.

5 of 5 Earpieces for Church Security April 9, 2021
Reviewer: Alex Ruiz from Celebration, FL United States  
Michael’s customer service was excellent.  He went way out of his way (in my opinion, above and beyond) to ensure our church selected the right earpiece for loud services.  Thanks Michael for your amazing work ethic!

5 of 5 Just What I Needed-Fantastic Earpeice October 14, 2013
Reviewer: Rick Emery from Jonesboro, AR United States  
I needed an earpiece that would be user friendly with a very high level of background noise.  I needed one that would allow me to hear as well as be heard during radio transmissions.  The Sentinel HN is everything I wanted and needed.  They don't come any better than this!  Also Custom Earpiece Black Diamond Radio has the finest customer service in the industry.  They truly want you to have the finest product and be more than 100% satisfied with your custom earpiece.  It is really a pleasure doing business with them and I will certainly be a return customer.
