AT&T headset
Love it... so much clearer and easier to work with... but more important is the service. Lawrence Shine was simply magnificent. He provided fantastic instructions while offering unbelievable patience.

I really like the headset for this product. The keypad I have not used. I would like to just get the headset without having to get the keypad.

Did not work
I could not get the dial pad to pair with the head set. This phone is now boxed up and stored where it will never be used.

Att marathon bundle
Acquired this product as a replacement for my Plantronics Calisto that failed less than a year into its service life.

Unfortunately the marathon is the only product on the market offering hands free, remote dialing functionality. While useable, it offers significantly less capability than the Calisto it replaces while costing about $100 more.

If you want hands free wireless calling for your analog phoneline, this looks like your only choice.

The key pad provides what is needed to work with our Avaya Partner phone system.

Very good performance
Quality of sound and of microphone are very good. Comfort is very good (I use the ear loop).For the Avaya (used to be ATT) phone that I use, the headset can connect without lifting the handset or using a lifter - a great convenience. But, the dialpad doesn't work so dialing has to be done from the phone. I'm giving a 4 and not 5 because there is minor "looseness" in the swivel on the headset that causes the mic to rub against my cheek. A rubber band holding it away has fixed that. Also, the batter connect strips on the headset were too recessed and I had to bend them out. Now the charging works fine.
Overall, the sound and mic quality and the ability to answer and go on-hook without lifting the handset make this the best wireless headset I've used.

I have not used the headset long enough to know whether it is what I am looking for. I will let you know after another month end which is the time I am the busiest.

Great system
I had a little trouble pairing the dial pad with the headset, but helped me through it. The headset is comfortable and the dial pad is just what I need to not clutter up my desk space.

Mixed reviews on this headset. The sound is fantastic - better than any headset I have ever had. Two problems - the earpiece is really uncomfortable and when I dial into a conference call with the headset on and then disconnect from the phone I dialed in on there is a terrible screeching sound that is heard by everyone on the call.

So far so good. The design and sound quality are fine. Your customer support is very good, making it quite easy to set up the product and do some troubleshooting.

The AT&T headset solved all the problems I was having with a previous headset. The clarity of the sound was crystal clear and just as sharp as the handset.

Fantastic solution
Old headset was dying and needed a new one - the AT&T Marathon is perfect in every way - better than the old one as it is wireless ! Love the clarity, the comfort and the ease of set up.

AT&T Marathon
I love the ability to be absolutely hands free and the range it has. The only thing I don't like is that it doesn't have a ring tone. If someone calls there is no way to know unless you are connected to another phone that has a ringer in it.

Works as advertised
This headset was easy to set up and worked immediately. I have used it only one day but had no problems using it. It has good range although I have not tested the claimed 500 feet capability. The only two items on my wish list is that the dial pad could be backlit. In low light it is difficult to see. The other is that the earpiece was a bit uncomfortable that one day I wore it. It comes with a headband which may be more comfortable but I don't like wearing that. I wear an earpiece at the office all week using an Office Runner headset which is very comfortable. The AT&T Marathon is used when I work at home. Maybe I will get used to it.

An amazing experience
I typically get all my headsets from, so needing a new one, I called for advice. This AT & T product was recommended and shipped promptly. The first one that arrived, didn't work properly, and the instruction manual said to contact AT & T directly. I did this twice, both times speaking to someone overseas who clearly didn't even understand how this particular headset combo worked. Shipping took a significant amount of time, and after the second one still didn't work, I called you folks directly. Once again, you got it spot on. Your rep diagnosed the problem immediately, suggested sending me an entirely new system, and when I confessed that I'd been at this for so long I was now up against a deadline, he shipped it to me overnight. As he predicted, the new system worked perfectly and set up went exactly as described in the manual. You could not have been more helpful or understanding, and the product, as your rep told me it would, meets my needs perfectly.
