Doesn't work with plasma TV [Posted on 2008-05-20]
I wanted to like this product. I have a set of Sennheiser RS140 wireless headphones that has fairly mediocre performance (lots of hiss and static from the radio transmission.) I was hoping that the IR technology in the Sony headphones would overcome this.
After I plugged my new Sony headphones in and gave them a try with my TV, it was a hundred times worse than the Sennheiser. The sound was mostly static, with faint hints of barely-audible dialog. The sound would improve with certain scenes on my TV, such as dark indoor scenes, but then get far worse during bright outdoor scenes (such as on the beach in an episode of Lost).
After hunting through the manual, I realized the problem: Buried in fine print, there's a statement "Plasma displays may interfere with normal operation of this system."
Sure enough, my Pioneer plasma TV was causing huge amounts of interference with the IR transmission. The bright outdoor scenes apparently generated IR interference, with rendered the dialog inaudible.
Saying that a plasma TV "may interfere" with operations is an understatement. This product is completely unusable with my plasma TV.
If this problem had been advertised with a warning "not suitable for plasma TVs," I'd be understanding. However, hiding this problem in the small print is unconscionable. At least Amazon seems to have a good return policy, which will be used in this case.
propietary battery and more [Posted on 2008-06-02]
-reading the literature,planning ahead, and noticing the odd square plastic adapter ends on the supplied aaa batteries, one is left with the impression that when the rechargeable batteries eventually fail one will need to get Sony BP HP550 batteries. The only link I found was in Europe and they looked to cost more than the headset pkg.!!
You can of course use alkaline aaa: but be sure NOT to put them in the charger!!!=
Now, it may be that any rechargeable battery will work-but it is not apparent in the literature, and I don't know for sure.
I am especially sorry about this since I sent a pair to my brother in law after reading all the rave reviews!
Also, although headphone ear foam replacement is referred to in the nmanual, no part number or source is offered-as with the batteries...Give yourself a break: pick another brand.
In this day and age when it is hard enough to try to be GREEN, is SONY helping?
Much better than radio wave headphones [Posted on 2008-06-11]
Work well enough to enable me to hear TV without blasting wife. May have to
play with hookup to get clear sound. Found that audio hookup at cable box
worked MUCH better than hookup from TV. Attenuation switch is also a bit
tricky in that if wrong it will cause hiss to get worse so try both on and off.
Overall VERY pleased with phones!!!
Sony headphones [Posted on 2008-06-26]
I really like the headphones. When they go out of range the sound just cuts out. My other headphones produced loud fuzzy static when they went out of range. The surround sound is interesting, but I could leave it also. The vibration affect doesn't do that much for me, but you can turn it off if you want, which is nice. They fit nice and are light. The sound is first class. I would buy them again.
Only get this if you don't like quality sound [Posted on 2008-06-27]
Well, I had high hopes for this product. I should have known better. Basically, you get a lot of static no matter how you adjust the knobs. Nuff said. Always that background noise, no matter what. This will work if you are watching TV in bed and don't want to wake the wife, but forget any sense of realism if you want immersive sound in a gamer environment or quality live music. I returned my set after about 40 minutes out of the box. Plus, you have to really aim the IR transmitter perfectly just to get a decent signal, and it cuts out any time you move around or place your hand in front of your face. Much better to suffer the wire than to purchase this. Don't do it.
