  1. Hamilton W

    I’ve been using wireless headsets for probably 15 years and this is the best one I’ve owned. The sound quality is excellent and the headset itself is the most comfortable I’ve used. Which surprised me, because I never wanted to go to a dual ear unit (too big looking and heavy feeling). This is neither. I love this thing!

  2. Ginger S.

    I have used the headset for my very first webinar, and loved it! I have a hearing loss and wear hearing aids, so being able to hear my audience was huge for me. This headset is comfy, delivers my voice well, and allowed me to adjust the sound so I could hear clearly. Well worth the price.

  3. Jennifer

    Amazing headset. I would strongly recommend this to anyone who works in an office that has more than two employees.

  4. Margie

    Our Triage nurses love the headset as they are in a crowded area and lots of background noise. This headset allows them to handle their calls efficiently.

  5. James

    Avoid this product. It is expensive and forces you to install a device that lifts up your phone and puts it back down gain so that you can use the headset. Does not work with the headset button. The phone lifter doesn’t reliably hang up your phone afterwards. I will often answer the phone and not be heard by the other end or I will sound faint. Too many moving pieces. Works well when it works but doesn’t work often enough.

  6. Stephen

    Volume and mute control is easy to find after the first use. Charges quick with great volume

  7. Fred

    This is the second headset system that i have purchased. The first one got accidently broken. The system works flawlessly. one of the best features is the ability fo custom set the volume. This is a very good solution for those with hearing issues

  8. hgarrison

    I have had a similar product from plantronics that I liked a lot more. The major complaint is I have to manually turn up the volume when I receive a phone call. Everyone says they can’t hear me till I turn up the volume. and I have to do that every time? I haven’t found any trouble shooting for this problem. Kind of Annoying

  9. Dee

    Like the headset, but doesn’t go as far as I thought.

  10. Michelle

    Headset works great and is comfortable. Covers both ears so sound is better for a busy, noisy office.

  11. Amy

    Lightweight, comfy, and you’re able to hear the customer clearly in a room full of other people talking

  12. Erika

    Our telephone specialists love the new headsets and find them really easy to use! Great to have in a busy call center.

  13. Patrick

    At this point you know you can buy this headset all over the internet, the difference is WHERE you buy it. You can stop your search, this is the company you have been looking for.

  14. JOHN

    Great product. Easy to set up. Good quality

  15. Christine

    Meets the need exactly. Well made and easy to set up. More impressive was the service we received. Would buy again from this vendor.

  16. A&A

    Only had the first one less than a week, but girls on front desk said it was very clear and no noise in the background. They do like the bi-ear better because it blocks out the room noise. Just installed the next 4 today.

  17. Steve

    Very satisfied with the service and quality of the product. The shipment of the product was quick, and I am very satisfied with the quality of service and product I ordered.

  18. Ecumen

    Purchased this head set for a staff member that is hard of hearing. It is really working good for them. They can hear the callers clearly.

  19. Dora

    It is a great product So lightweight sometimes I forget I have it on. Good and clear, good loud. I love it.

  20. Ryan

    Overall I give it 5 stars! Great headset, comfortable, shipping was fast, good customer service. Sound is very clear.

  21. Dianne

    Great headset, comfortable, and sound is very clear. We sit in cubicles so the dual earpieces really help to cut down on the noise from my co-workers. Shipped quickly and easy to install.
