VERY EASY TO INSTALL. THIS PRODUCT IS A REAL PEACE MAKER, NO MORE SHOUTING ABOVE THE VOLUME, AND NO MORE CRYING TO TURN THE VOLUME DOWN ON THE TV. PLUS IT IS A QUALITY HEARING DEVICE FOR THE HEARING IMPAIRED.
Someone at Sony realized that the volume control shouldn't be positioned so that you can't rest the back of your head against a pillow. I've been using a pair of Sony MDR-RF925RK phones for about a year after giving up on Sennheiser phones that had great sound but severe problems with drop out. Bottom line: good product, good value. They need recharging more frequently than previous RF phones I have used, but the recharger cradle is easy to use so recharging is not a nuisance. The sound is very good (though not "audiophile" quality), there is very little problem with dropout, and hissing is less than with any of the previous phones I have used. They are comfortable and the controls are easy to use.
After a great deal of trouble shooting, I found that the power on/off switch in the headband was the culprit. When the headset is positioned over my ears, the provided momentaty switch barely closes and any motion on my part causes it to turn off/on and pop. The plastic case is an insulator but is quite prone to electrostatic build up which in turn acts as a conductor between the TV set and itself. My Background: University degreed in electonics(1) Problems:Excessive popping sounds. Trimming all of the 'long' pigtails solved the shocking problem. I wear hat size 7 1/4 and am bald. Really BAD MANUFACTURE.I DEFINITELY DO NOT RECOMMEND BUYING THIS PRODUCT.
The switch is activated when the headset is put on causing a small slide to depress the plunger when the headband is set onto the head. I found that the component pigtails of the printed wiring board contacted the outer case and that the grounds associated with the RCA jacks connecting the base unit to the TV set were also touching the case. Yes I took it apart. Yes I did take it apart. Plastic case and pretty much DC so why a tingling shock.
Many reasons and theories on the Internet about popping sounds in wireless headphones. REALLY BAD DESIGN.(2) A tingling shock whenever I picked up the base unit. The problem is two-fold the provided switch is 'cheap' and the whole headset mechanism must have been designed and tested by a people with large heads full of hair. The switch and assembly are as designed and manufactured properly HOWEVER, the switch is 'cheap' and momentary, i.e., when a small plunger in the switch is depressed the power goes on; off when the plunger is released. I replaced the switch with an external manual operated on/off switch and the popping is gone.
the product worked great even through walls but just to big for him the fact of the matter is that they are just to bulky and not comfortable to him. i got these as a Christmas present for my hearing impaired grand father. needless to say he wont use them.
Oh, one other thing. These new RF925RK headsets are like awesome compared to the older Sony set. Sound fidelity is not my principal concern, as I am not an audiophile, but clarity and richness is appreciated. In fact, the inner ear pads are ergonomically profiled to fit over the ear (asymmetrical - left and right are different).
These Sony headphones are my fourth try with wireless headphones, and these Sonys are the best so far. I can't stress enough how important it is that Sony wireless Rf phones turn themselves off automatically when you removed them from your head. These Sony phones sound terrific. My first wireless headphones were IR based (infrared), which left me totally underwhelmed in terms of sound quality and line-of-sight range.
The new Sony uses an induction charging base, which sure beats the heck out of the previous method of lining up those tiny contact pins -- always a hassle. Also, the Sony rechargable AAA batteries can be replaced with regular Alkaline AAAs in a in case you forget to charge-up these phones. My next phones were Sony's older 900Mhz RF model, which I used regularly for at least three years until last week. There is little or no background noise (dead quiet), and the ear pads are larger so they completely cover the ears.
