Nice Headset
I'm quite happy with this headset. I especially like that it has a power supply so I never have to worry about a dead battery or recycling batteries. We've been customers of Headsets.com since 2006 and have always been pleased with how well they've taken care of us.

Good product - did take us a while to figure out how to attach cushion piece for over the ear.

This head set seems to be working well.
This headset seems to be working well, after we worked with the company who installed our phone system and worked the bugs out. All seems to be well. Thank you for the tootsie rolls, it was very nice of you. We especially enjoy your great customer service!!

Very satisfied overall.
The headsets we purchased are very convenient and function great. The over-the-head function is what we have decided works best for us. The over-the-ear piece does not fit well at all. The only other thing that we are noticing is that we will probably look to upgrade to a wireless headset at some point in the future.

Happy customer
Used this headset at work and bought it for home office. Good volume control if more volume is needed. Person on other end does not know if you mute.

Love it...
I used this set for years, with the over-ear style. I have a hard time getting headsets that fit, in either style so these were great! Clarity is great and very simple to hook up and use, even with older model phone systems. The only downside I have found is it is not a quick-connect cord, so you have to take it off to leave your desk/area.

This thing is a waste of money. All it does is feedback and buzz. It's the worst thing I have ever bought

Great product and customer service!
At first I was skeptical on the quality of the headset at such a low price. All of that was changed when I made my first call. The headset allows hands free calling and the recipients report that the call quality is excellent

Overall, we really like this headset. Would be great if it had a quick disconnect as our employees tend to switch desks and get up and down a lot.

Superb Product
I love my new headset. Being hearing impaired, it has allowed me to use the phone like a regular person. Now all I have to do is ask the caller to slow down!!

It's much better than the previous model I was using. It's much more comfortable and the audio quality is better.
The customer service was superb. The operator was thorough and friendly. Even though I had ordered the wrong model, the company honored the guarantee, and I was able to upgrade to what I really needed and to what was compatible with my system.

I've already been recommending the product and your company to my co-workers.

To use this headset is really simple, it is great to be handsfree. It is very comfortable and you can hear clearly. I love it.

Plantronics S12
The sound quality and ease of use of the system is superb. The length of the cord attached to the headset could be a little longer and the mouth piece probably doesn't light up quite enough to make sure people know I'm on the phone because many people have told me they didn't notice it.

Amplified Headset
We loved the customer service we received from the representative that helped us. He was very helpful. We like the headset. It does the job of amplifying the sound so that we can utilize the digital phone system that we purchased. The cord however is a little short for moving around, that may need to be addressed with an extension to the cord or returning the product for a cordless. The headset its self is a little bulky, but for the price we think it works well.

Feedback on S12
I like the ease of use and setup but most of all the "in use light" on the boom is the most beneficial. All headsets should have this light in my opinion. I do wish there was a wireless option with the light.

Like the sound quality. Callers say they can hear me much better than they did on my previous headset.
Would like it if the cord that attached the phone and unit were longer.
Overall, very satisfied.

customer image Patrick Dwyer
Have try this product before and it work great for what I do. Easy to set up and clear. Just remember to tune the button on the side and you are up and running. Quick delivery. Ordered on Friday and received it on Monday. Love the over the ear instead of over the head mount.

Plantronics S12 Headset System
Superb! What a difference in sound from what I was using previously! A colleague recommended the Plantronics brand and it's easy to see why. Everyone that I've spoken to on our marketing team has remarked on how clear the sound is. And it's comfortable to wear for the hours that I spend on the phone.

Plantronics headset with firefly mic
We switched our entire organization to the firefly mic headsets. In the past it was impossible to know if the person at the desk next to you was on the phone, but now with the firefly, a quick glance tells it all. An excellent improvement!

Excellent Value
We purchased the Plantronics S12 systems for our office and are very satisfied with the quality. The all-in-one system was the best value and provides easy setup, clear sound, and is simple to use. I liked the convertible option, but was slightly disappointed with the ear piece fit, but the over-the-head style is weightless and comfortable. I was also impressed with the service of the customer reps at headsets.com. They made my purchase quick and enjoyable. Thank you!

The best headset system on here to get!
I work for a car dealership and I am constantly on the phone, what better headset system to have than the Plantronics S12 System. My favorite features of this system is the lighted indicator on the side, it let's anyone who may walk up to me, know that I am on the phone. It also gives the headset a lot of class. It is extremely versatile, you can choose to wear it on your ear or over your head, and you can even switch sides that it is on, as easy as 1...2...3! The amplifier it's self not only makes it better to hear the customer but you can also adjust your volume as well. Really a great, inexpensive, and recommended system.
