  1. Absolutely Amazing!

    Posted by Marjeanne LoBese on 2nd Nov 2015

    I am surprised how much this changed the level of work I do, I feel like I am able to multi-task way better, the environment I work in is literally nonstop and this little guy not only is light weight, but totally helps get my job done. I can put someone on hold, ( mute ) so awesome, when behind seems and you don’t want them to hear you! I love this and I can already feel my back healing! And my neck is doing amazing, been a little over a month and I can honestly say our would office is getting one! Our rep Doug Merritt, not only walked me tho setup, but he set everything up so when he left all was good to go. He is extremely helpful and answered all my questions!

  2. A Great Product

    Posted by Barbara on 15th Jun 2015

    I was a bit wary at first but once I got used to having something in my ear I was "good to go"! I love having both hands to work with while on a call and no more taco neck! I am up and down a lot in my job and being able to answer the phone when across the office is great - - no more running around furniture or people to catch a call. Thanks Doug for your product and support!

  3. Comfortable and Reliable

    The headset paired with the handset lifter is a great tool for our secretaries. I am on the phone quite a bit and have found this unit to be very comfortable and very good clarity. The support is local and is excellent. I would give this unit a "two thumbs up" as well.

  4. Small and sleek

    Posted by Vicky on 20th Apr 2015

    This headset has been a great functioning headset for my staff. Very light weight and great clarity. The unit seems to hold a charge well. We have about 20 of them now as we replaced the older version. Love the Pairing feature for training purpose of the staff. I recommend this headset... you will not be disappointed. Support is great as well.

  5. A great Value

    Posted by Unknown on 17th Apr 2015

    We have dozens of these installed in our company and have found the headset very reliable. The range seems to be very good and the clarity at the outer range limit continues to be acceptable. They get a "two thumbs up" from us!!

  6. Nice device

    Posted by Tom on 17th Apr 2015

    This device is easy to use and and is good to keep a long charge. The earpiece provides clear conversation and is not heavy on the ear.

  • 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”
