After replacing the power supply it works great.
After navigating the online places and waiting a long time, I finally got someone to call me back And we figured out what the problem was. I do need a replacement power supply..

Comfy, great sound, and Instant Mute!

Nothing beats Sennheiser for audio excellence, we all know that. The specifics that I appreciate with the RS 175: option of audio optical setup, this helps to leave my USBs available. Also, the 'Instant Mute' feature is wonderful. While listening to something on my PC, sometimes I am in another room working on a project when a loud commercial jumps up! Loud! The Instant Mute saves my ears every time. Thanks. The range is very good, too. Very happy with this Sennheiser set.

Hmm, well. I don't know yet. Other than the instructions don't match the product.

I started messing with the 175's tonight after they came yesterday. Which I was stoked about! I've read some, and heard about the quality! I started out with the connection and installing the batteries. Unfortunately, the instructions don't match the product. I'm not a good direction guy, but what guy is, but the press and hold to power the unit isn't a press and hold at all. Only LED. After pressing it like I was putting my thumb through it. I figured it was stuck in; button compressed or something. After noticing the headphones have a power button on them which in turn lights the LED on the unit. 🙄😂 that's as far as I got tonight. Haha. Been a long day. More tomorrow! 😄
