  1. Stewart A (verified owner)

    Excellent hands-free telephone

  2. Nathan H

    Product is great, service is great, salesperson (Cindy) is great. Couldn’t imagine going anywhere else 🙂

  3. Nkosi A

    The headset works fine, but when using the ear piece alone, its doesn’t feel secure.

  4. M. Lee

    The unit is great however you have to pick up your handset on your telephone to answer, this is not a good thing if you work from home on the phone. There is no button to push in order to answer the phone via the S-12 unit. This is a major downside of this unit. And its not divulged in any of the ads.

  5. Diane B

    I love the quality and convenience of the headset.

  6. RH

    Headset is easy to use and has a clear quality sound. This is a replacement for a Plantronics unit that I had used for 10 years. The console is easier to access and the use of a transformer for power, instead of batteries, is a great improvement.

  7. Jennie H

    This is a good headset. The only thing I would change is you cannot block out the outside noises.

  8. John T

    No handset lifter available. Major downside.

  9. Kathy C

    Used you for years – love this set – would not change a thing.
