Sennheiser RS 120 Consumer Headphones Review

Bottom-Line: If you are in need of quality wireless headphones you could do a lot worse than the Sennheiser RS-120. 

The Sennheiser RS-120 Wireless Headphones are designed for use with Hi-Fi audio, television, or computer.  The open air RF (radio Frequency) German-made headphones are designed to provide a rich palate of aural sound (frequency response rated at 22Hz - 19500Hz) through walls as well as ceilings allowing one to roam throughout the house while listening to your tunes. 

Power to the headphones is provided by a set of NiMH (size AAA) batteries.  These batteries are in turn recharged by putting the headphones on their transmitter base; said base can be mounted to a wall. The entire system-transmitter base and headphones weigh in at just 8.1 ounces, but the headphones are rather large; large but comfortable. 

Use

In and around my house the sound quality from the Sennheiser RS-120 was outstanding!  I was able to roam throughout the house without experiencing and signal degradation or interference.  Frequency response was suburb, and the overall sound was crisp and enjoyable.  It helps that there is no frequency overlap in my house; i.e. my cordless phone operate at 5.8GHz and my wireless LAN operates at 2.4GHz.  The Sennheiser RS-120 operate on a radio frequency of 926MHz         

Work is a different story altogether.  The Sennheiser RS-120's still work for the most part but there is some interference from my other wireless accessories, including my cordless keyboard and mouse and cordless Plantronics headset.  I am able to change the channel and fine tune the frequency when needed however, and for the most part I am able to listen to music and or radio interference free. 

The range inside my standard office building setting is outstanding through doors and walls.  I can roam a considerable distance before static degrades the signal; very impressive.

My Viewpoint

I like my new Sennheiser RS-120 Wireless Headphones, so much so that I am planning on purchasing a set for my home stereo.  Yes, there is some interference in my work setting with other devices, but I expected that and systems ability to allow for fine tuning is a definite plus.  If you are in need of quality wireless headphones you could do a lot worse than the Sennheiser RS-120.
