## Customer Reviews

### ⭐⭐⭐⭐⭐ works great and gives me the flexibility I need when using the telephone
*by L***S on March 22, 2014*

The initial adapter that came with the headset was not compatible with the AT&T model 1187 telephone I use for land line calls. After several contacts with Sennheiser Customer Support they finally added the AT&T model phones to the reference table they have on their website and even suggested the adapter to use with my particular type phone. I ordered the adapter from Merritt Communications and it arrived earlier than expected leaving me with high regards for the Customer Support groups at Merritt Communications as well as Sennheiser.I participate in weekly group telecoms which can last for a couple of hours. Most of the calls are accompanied by presentations on the computer. This adapter allows me flexibility to be on the phone without using the speaker phone or having to worry about holding the hand held receiver the entire time. This frees my hands to be on the computer as needed to support the presentation being made.This cable adapter certainly meets my needs and I would recommend it to anyone having similar requirements. Obviously this particular adapter is not meant for cell phones but works great with land lines.

### ⭐⭐⭐⭐⭐ Using with Sennheiser SC260 and Nortel Phone
*by P***8 on January 7, 2013*

Works great with my Nortel M3xxx phone. Audio sounds great over this cable. I had bought the CSTD-08 which was the wrong cable for my Nortel phone initially. This cable fixed it all (I even tried to re-wire the 08 cable, but everything was super quiet on it and the microphone didn't work).

### ⭐ Doesn't work.
*by S***I on March 25, 2014*

Microphone of my headset doesn't work with this adapter. Only speakers work.I use Sennheiser Binaural Headset (CC 550).Waste of money.Too bad I can't return this product as I don't live in the U.S. anymore.
