  2. Five refurbished Plantronics CS351n w/Lifter

    Posted by Steve Weberman on 28th Sep 2015

    We purchased 5 of these units from Merritt for our Inside Sales team and selected this model based on another user's recommendation. The headsets, charging stations, and lifters all work as advertised. For a refurbished product, the quality was near new and works great. I would recommend this headset and also highly recommend Merritt. They are easy to contact (email, chat and phone) and very responsive with a reply. In addition, the refurbished product comes with a 1 year warranty!


  • 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”
