Cingular Go Phone: Remanufactured Sennheiser RS 140 Wireless Balanced Headphones Review

This is the best headset I have ever owned. It has superior quality sound and blocks almost 100% of external noise, an invaluable feature for folks who live in apartments or otherwise noisy neighborhoods as I do. It also allows you to change the balance of Right and Left and use a Compression feature should you be suffering from some hearing loss. Further, the Amazon price, especially on the refurbished unit, simply can not be beat. However, I have to confess that I almost returned the headset at first for a very foolish reason. It kept shutting off on me so I thought it had to do with interference from aircraft that regularly fly near my location, or my crazy neighbor's wireless equipment, etc. The refurbished products do not come with a manual so I contacted Sennheiser by e-mail and received a prompt response, a user manual, and a phone number to call with any additional questions. It ultimately turned out that I had simply failed to properly charge the complimentary NiMh batteries! :-) I felt like a colossal fool! :-) I also discovered that if you connect it to the audio connectors on the back of your TV or, even better, a receiver if you have one, you get much better results; the output of "Headphone" jacks is not anywhere as good and most are monaural anyway.
I have my headset connected to my Home Theater Receiver now and it works like a charm. Anyway, I am glad I did not return it. It is an excellent product from a company that seems to provide outstanding service. If you buy this, and I would most definitely recommend that you do, just e-mail them and get a user guide .

Product Description:
Experience total freedom of movement and exceptional sound with the remanufactured Sennheiser RS 140 wireless headphones. With a switchable dynamic compression system that makes speech sound remarkably good and a balance control for optimum right/left volume adjustments, the RS 140s are ideal for listening to TV shows, DVD movies, or music while the rest of the house is asleep. With the RS 140s, you can move around freely--even to the downstairs laundry or upstairs bathroom--while enjoying uninterrupted, audiophile-class sound. They even include an adjustable output level that ranges notably high to compensate for moderate hearing loss.
While many wireless headphones suffer from poor reception, the RS 140s have the problem licked with intelligent auto tuning and a self-learning automatic signal level control that provides maximum signal reception and a range of up to 150 meters. The headphones are lightweight, too, making them comfortable to wear. The included transmitter and stand make recharging the headphone batteries easy; simply hang the headphones on the charging cradle and you're good to go. With an operating time of approximately 23 hours, though, plan on spending most of your time enjoying rich sound and maximum mobility.
The RS 140's specifications vary from a frequency response of 18 Hz to 21 kHz to a total harmonic distortion of less than 0.5 percent to a weight of around 0.61 pounds. In addition, the transmitter, which is wall-mountable, can connect to a variety of components thanks to its 3.5 mm, 6.3 mm, and RCA plugs. The entire bundle is backed by a 90-day warranty.
