In short, know what your getting into, and dont whine when it doesnt work as good as a decent set of hard-wire headphones. Knowledge is the key here (...)

Review : JVC didn't consider aerodynamics when they designed this headphone. The HAW300RF flies awkward, when you throw it against a preferably hard surface. Also, it requires several impacts before breaking and doesn't shatter to a million pieces taking out the fun from even destroying it L (also it causes serious dents on the wall)

Buy a porcelain panda to put on the top of your TV! you're better off.

If you bought this already... My advice is, just simply don't turn it on.
But if you do, first expect that you have to "tune" it to the
frequency the transmitter (the base unit) *questionably* operates on. You have to toy with it for a good while to get a VERY! lo-fi signal at best. (DO NOT expect a Hi-Fi sound or even anything near)

Now the fun comes! The unit occasionally loses the signal by turning your head one way or another and 120dB white noise will cut bat shaped Halloween cookies from your eardrums. I guess the idea is that after the third time this happens, you won't be able to tell the difference between Hi-Fi and Lo-Fi anyway, so you'll stop complaining about the sound quality.

Another funny design trick is that the base unit automatically turns off after a certain [short] period of silence. For example when you're searching for a song on a tape. ... what happens is when the base unit turns itself off, the head unit blasts a full throttle brain damage level noise... right through your head. I was witnessed several times breaking Charles Austin's world record of the high jump (that's 2.39m!)

Very disappointing. Unusable

Very happy with my purchase (Rating: 5.00)
Review : I purchased this for my 72 year old father who has poor hearing and was having difficulty making out what was being said on the tv or when playing his vcr tapes (he has chosen not to wear his hearing aid). He also needed a way not to disturb his wife at night when listening to the tv. After doing considerable research, I decided on wireless, non-infrared, headphones (he will sometimes fall asleep on the bed still listening to the radio or tv, so I needed something that would handle that scenario) and have just hooked up the new headphones tonight.

I have always been happy with the JVC brand in the past owning that brand in a handheld camcorder, two tvs and vcr. I was deliberating between the JVC and a $20 more expensive Sony model in the same headphone category. On Walmart's website, they had the same JVC headphone but for $20 more and didn't even have it stocked locally.

I therefore decided to go with this JVC model from Amazon. It arrived more quickly than I expected even with the free shipping. The quality of the materials were very much up to expectations. When I tried the headphones first with an older model VCR that did not allow me to plug in both the white and red connectors but only the single end (I'm not an electronics expert obviously), the sound was very low and pretty much drowned out by the static. When I used a vcr that was only 4 years old that had a place for the red and white plugs, the sound was very clear with plenty of volume and no static once I tuned them in.

Since we are not using this to listen to music, I won't venture an opinion as to how perfectly it reproduces that quality. For tv/vcr use, it comes across as equivalent to what we could hear before and my general impression is that of a 900 MHz cordless phone, only with headphones instead. I imagine I could also use it to listen to c-span.org audio/video archived recordings on my computer as long as I'm not moving around since it tends to go through static areas, but even then if sufficiently motivated (while cooking dinner for example), I feel they would probably be fine.

I found the controls very handy which surprised me given some earlier reviews. I wish there was a more intuitive way of knowing absolutely that the batteries were recharging (since I worry whether the headphones have "seated" correctly) and when they have fully recharged. If there is no audio signal, there is a light that helps as a clue, but since my father is using this with a vcr that is always on (fewer decisions to make), the light stays the same. I consider this only a minor inconvenience. From what I know now and for the application I'm using it for, I am very happy with the purchase.

Not ready for prime time (Rating: 1.00)
Review : Just not worth the money. Wouldn't be worth even $20 because it just doesn't work well. Wasn't looking for perfect sound but way too much static even when sitting right in front of the receiver with a full charge on the headphones. I'm not sure if it's just this product (this was my 1st set) or if wireless headphones in general aren't ready for general use. I disliked it so much I returned them.

They're not bad! (Rating: 5.00)
Review : I've had these headphones for a month now. I decided to buy them regardless of some bad reviews. These are radio signal receiving headphones, they recieve a signal from the base/charging unit. I have it plugged into my computer at work and they're excellent. The sound quality is good for just listening while you're working do not buy these if you're into hearing every detail. Sure, there's some radio static in the background but its nothing that will make you toss them across the room. Definetly worth the price!
