  1. Game Changer

    Posted by Kyle Mestayer on 4th Oct 2016

    Best investment for my employees. They love the mobility and efficiency these headsets provide. I love the hand on customer care that I receive from Merritt Comm.

  2. Comfortable

    My new headset is sleek, stylish, extremely comfortable and easy to use. I also love that I can call if there is a problem.

  3. Excellent Product!

    Simple process to obtain 2 additional units for my office since we had success with our initial order. Highly recommend the product, and even more Merritt Communications. The cost with Merritt was less than half what I found with other online resources.

  4. Great replacement!

    One of our headsets was acting up. We didn't know if it was the headset itself or the base unit. Plantronics support said we'd need to replace the entire unit. We opted to buy this refurbished unit as a cost effective way to "kill two birds with one stone". Turns out it was the base unit and now we have a spare headset, which we are sure to need at some point, for a fraction of the cost of a new unit.

  • 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”
