  1. Great Product

    Posted by Kathy on 31st Aug 2017

    This product works great. I had been using a plug in headset for years and wasn't able to leave my desk. Now I can get up, move around, and answer a phone call anywhere. I had the unit for 3 months and had a problem with the caller hearing me. I called Merritt and spoke with Dustin. He arranged for a new unit to be shipped to me. I set up the unit and had an issue with the unit not connecting to an outside line. David worked with me and we tested through all the possible reasons why this might be happening. He then had me switch out the new ear piece with the old one. It worked! So the old charging station was defective and the new earpiece was defective. What's the chances of that happening! Thank you David for taking so much time working with me to solve the problem. Thank you Dustin for getting the replacement unit to me so quickly. Thank you McKenzie for checking up and making sure I received the replacement product and offering any assistance I might need. Great company to work with!

  2. 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!

  3. 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!

  4. Comfortable and Reliable

    Posted by Pam on May 21, 2015 on 21st May 2015

    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.

  5. 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.

  6. 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!!

  7. 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.

  8. Comfortable and Classy

    Posted by Unknown on 24th Jan 2015

    Great headset, super lightweight and love the battery life
