  1. Absolutely fantastic!

    Posted by Unknown on 11th Mar 2016

    My co workers and I are very fortunate we have a great employer who ordered these for us, since we are on the phones 9 hours a day. I wasn't sure how well these would work at first. They have exceeded my expectations and I can honestly say that I couldn't live without this headset! I have used corded headsets in the past and you always feel tethered to your phone and desk and the cord always gets in the way! These don't and you find yourself forgetting that you are even wearing one. I love how I can answer the phone while I am away from my desk, so I can multi task so much easier than I could on a regular headset/phone. The sound quality is superb and there are ways to adjust the volume coming in or going out. I also will add that the battery in this unit is ample and lasts all day---just be sure you put your earpiece in the charging cradle at the end of your workday. You can't possibly go wrong with this headset and will be so glad you purchased it! Happy employees always make happy customers!


  • I was searching the entire internet for a headset and ended up landing on Merritt Communications website. I called and was greeted by a gentleman named David. From the very first call until our 5th conversation he was the most helpful salesman I have ever encountered on the internet.

    He went way above and beyond and instead of just selling me what I asked for, he told me about a solution that would save me money and be a better fit for my company. Hands down anything related to office headsets this is the GO-TO COMPANY! Their return policy and warranty is hands down the best in the business. They made me feel comfortable making an online purchase. ~ Mark Z. “The Real Estate Guy”
