4 out of 5 eggsWorks well, but not for an audiophile

Pros: Excellent range (200+ feet unobstructed). Very comfortable. Excellent battery charge life. I've never had it run out of juice while wearing it, but I have picked it up to use it and found it dead after I failed to properly reseat it on its charging station the night before.

Cons: There is a very slight hiss which can be bothersome when listening to soft music such as arias, but cannot be heard in louder music. If there is a strong magnetic field between the headset and the base station, the signal can become choppy. In particular, an active microwave can put a good buzz in the music. Also, the headset's antenna has an extremely tiny blind spot. If I hold my head just right (which is very hard to do), I can make the headset loose the base station's signal at any range.

Other Thoughts: Since I'm not an audiophile, I'm very pleased with this product and would recommend it to anyone who wants to be able to roam around and still listen to music privately.

Sometimes, after my playlist runs out, I can hear other signals in the background noise. However, I've never had these signals overcome that of the base station.

5 out of 5 eggsGreat wireless headphones RS-140s

Pros: The sound quality is great as far as TV viewing goes. I haven't used them for music yet, but I expect music to be good too. I really don't hear any significant hiss. An occasional pop in dead silence, but that's even rare. I only mention it because I've read comments about hiss and for me, it's barely noticeable, if you can even hear it at all.

The price was good and these are worth the price for sure.

They come with rechargeable batteries and recharging is easy. Just put them on the base.

Setup is super easy. Comes with a variety of connectors so virtually any analog situation should work.

Volume, balance, On-Off and RF Channel on the headphone. You can use multiple headphones if you want to buy more. You can also use multiple bases in the same room. Just set the RF channels differently on the bases (not sure how many.. but two works fine). Each headphone can be switched to listen to any base unit(s) you have with the channel selector on the headphone.

Cons: Not really any cons. These aren't the lowest priced wireless headphones, but I think they are worth the price. I prefer these "Closed" headphones versus the Open air models, even though these cost more.

Some said they were bulky, but I didn't think so. They're actually pretty comfortable.

Other Thoughts: We have two of these in our RV. In the past, it was tough to hear the TV with all the road noise while enroute. Plus, as the driver, I'd rather not hear whats on the TV while I'm driving along. So we have two bases.. two headphones. One for the back bedroom, and one for the front living area. It worked out great. When not using the RV, these are in the house for late night viewing while others are sleeping.

All in all.. very happy with these.

4 out of 5 eggsAlright, but expensive

Pros: Good sound quality and fairly flat response when set up correctly (Flat = good when it comes to speakers/headphones, it means all frequencies are equally represented by the speaker/circuitry.) Very good range, i get limited reception out side my brick house!

Cons: As others have posted there is a hiss that is created by RF interference. I often get crackles and large amounts of static depending on how the headphones face the reciever which can be VERY annoying. Although from what ive read about others there seems to be similar problems with most RF sets, just interference i guess.

Other Thoughts: I still use them, just set them up with the comp/reciver/tv volume up all the way and then tune down the volume on the headset and it minimizes the ambiant hiss, but i still get interference from other devices, AKA monitor/computer. In my opinion they are too expensive for the flaws, if you are paying this much you are an audiophile like me and want what you pay for, these just dont deliever for the price thats all...

5 out of 5 eggsVery good quality

Pros: Sound is great. Great range all over my small house, even through many walls into the garage. Excellent battery life for generic rechargeables.

Cons: Not too comfortable to lay down in bed watching TV. Bulky. Expensive.

Other Thoughts: Worth the price but this is my first set of good wireless headphones.

5 out of 5 eggsGreat headphones

Pros: Great sound, little to no hiss, comfortable. Base recharger easy to use, long range.

Cons: 3 minute auto turnoff could be a bit annoying for people who like to keep their headphones on all the time even when they're not using them. It's a non issue if you turn them off when you're not listening.

Other Thoughts: People who are complaining about the hiss probably aren't doing what you should always do with wireless headphones: turn all of your computers volume settings as high as they go, both the Windows volume and in the program itself. That way you can lower the volume (amplification) on the headphones. Believe me, this works like a charm, and the hiss on mine is practically inaudible.

1 out of 5 eggsPiece of junk

Pros: Fits well over the head and ears.

Cons: Pretty much everything. Reception is very bad even when in the same room as base station. Lot if hishing and cracking sounds. Loose audio every X seconds.

4 out of 5 eggsGood for the genre

Pros: Best of the bunch - had 3 other wireless headphones, mostly sub-$50 types, these were far superior, and actually useable. Very convenient to use, having the recharger integrated in the stand means they're always ready when I need them.

Cons: Enjoyment depends on usage - I use them for gaming, so there's long periods of relative quiet where the hiss is noticable. And the Auto off "feature" is kinda a pain. It seems to kick in more often than I'd like

3 out of 5 eggsPretty good...

Pros: Wireless, good recharging system, long operating time.

Cons: High SNR, Auto turn off, Interference

Other Thoughts: These headphones are pretty good. The SNR ratio on them is pretty high, and you will hear constant hissing with them. The hissing is really bad when you first turn them on, but tones down a bit after use. But it is always still there. The auto turn off feature is very annoying. If there is no sound within a given time (or it is very quite), you a treated to 6 very loud beeps then the headphones are turned off. If you play a sound again, it will take them at least 6 seconds to turn back on, thus missing 6 seconds of whatever you were playing. On several occasions i've had them cut off when playing games with quite atmospheres.

1 out of 5 eggsToo much interference, questionable functionality...

Pros: Good build materials, headphones cover ears well.

Cons: Everything else.

Other Thoughts: I read all the glowing reviews on Newegg and decided to try these. They were terrible. The interference was awful even 12 inches from the base and turning my head while wearing the headphones caused a static interruption. The base unit turns itself on and off automatically if it receives audio signal but it cuts off the first 6-10 seconds of sound which is annoying. When it detects no signal it beeps the headset with a very loud piercing beep that is painful to the ears. The base unit also had trouble determining that the headphones were sitting on it for charging.

2 out of 5 eggsFantastic, if you can't hear

Pros: Volume is fairly loud. Very easy gain adjustment. Cool look and neat way of recharging.

Cons: RF technology is still not "there" yet. There is a small amount of hissing at all times, but moving around the room, or to other rooms causes loud crackles from the interference of other electronics. You have to position the headphones just so to recharge them. Also, RF channel changing is necessary, which leads to more static.

Other Thoughts: I would only reccomend these to someone who has dificulty hearing the television; so the transmitter is in the same room, and they probably won't notice the hissing and crackling because of their poor hearing. If you like to enjoy music, especially at louder volumes, I would look into another pair and maybe even a different technology.
