Crystal Clear
My iPhone connected right up, just remember to push the "on" button for the headset after you take it off the base. Clear voice, easy to use - I keep forgetting where I left my phone...

The connector works great. I had been reluctant to order it due to the high price. But it does a great job.

It works well
I was surprised to find that this product works well. Very well. I bought it so I can use my iPad 3 with my Sennheiser wireless headset - while on an extended trip away from the office. Because of this device, I no longer need to carry a laptop. Thanks.

Adapter Cord ...
Easy to install and works as promised. The only drawback is that the cord is too short. The phone has to be right next to the base.
