RS 110

RS 110 Wireless Stereo Headphones

These Sennheiser entry-level headphones are an ideal choice for people who like to walk around the room while listening to their favorite tunes. The system features a 900MHz wireless transmitter that broadcasts a powerful signal throughout the room - and even through walls and ceilings. Should listeners wander upstairs or outside, they can still enjoy the headphones' warm sound and strong bass response provided they stay within range.

The RS-110 headphones are also ideal for listening to late-night TV without waking up the rest of the house. And thanks to the lightweight, soft earpads, the phones feel comfortable through hours of use. In addition, the phones include replaceable parts, so users don't have to buy new headphones each time a part wears out, along with a pair of AAA batteries. So don't get tied down by restrictive cables. With these Sennheiser headphones, users will enjoy a whole new world of wireless convenience.

1 out of 5 eggsWorst headphones ever

Pros: None, cheap?

Cons: they simply don't work. low quality, audio cuts out often due to transmitter cutting out and which causes the headphones to BLAST static into your ear.

Other Thoughts: the review guidelines prohibit me from explaining how I feel further.

1 out of 5 eggsWorst $80 I ever spent

Pros: I can sometimes hear sound

Cons: Drops if quiet too long, or randomly. High static. By drops I mean the transmitter shuts off (not the headphones), the headphones blast static at high volume. These are frankly a waste of money. I'm currently trying to RMA then back as defective we'll see how that goes. I'm just gunna go buy a 10' cable.

Other Thoughts: I see the marked it down $10. Frankly I've $15 head phones that are better. Also it should be noted the reason that all these comments are recent is because NewEgg had this flagged as openbox/used merch at first.

4 out of 5 eggsDecent, for the money, but not high-end

Pros: Cheap (price)
Simple to use/setup

Cons: The transmitter turns off if no audio is being played, which kind of sucks on computers (which is what I bought this for).

Other Thoughts: I wish I would have gotten the canned version. My ears get hot while using them and the sound is only okay. The range is decent, though the low end lacks any punch.

2 out of 5 eggsupdate

Pros: was working great

Cons: starting to get fuzzy and unusable!

Other Thoughts: heres what happened, i bought these a few months back and spent about an hour trying to get them to work properly, partly my fault for not doing it right to start with. once i got it working they worked great! i could use themj when mowing (through 4 inside walls and a brick wall, then a good 80-120 steps from the house to the street, big yard!) i loved them, batteries lasted a week or so, used them A TON. over the past few weeks they've been getting fuzzier and fuzzier to the point its better to put on subtitles and watch silent film then to have sound! ive tried re-tuning it on all 3 channels, no difference, tried using new batteries AND a different brand! still not that. cussing at them still doesnt fix them, and leaving them in a shelf all day doesnt seem to make them want to work properly... super disappointed, i bought them from newegg. i wish i could get them swapped out or get credit towards a different pair...ohwell, cant always make good decisions...

over view
great for first few months.
started getting fuzzy.
unable to easily fix.
not worth your money if you dont own a money tree...
disappointed from all the good reviews.

5 out of 5 eggsMakes the deaf(ish) hear again

Pros: Loud and Clear
Minimal/No Radio Interference
Long Range - 50 feet +

Cons: None - Father didn't make the "how do I make this thing work" call

Other Thoughts: Bought this for my father for christmas, he and posts have similar capabilities when it comes to hearing...
According to my mother, the house no longer shakes simply because he wants to hear the TV.

5 out of 5 eggsWell made product.

Pros: It is a nice product for $50 price range. It is lightweight and comfortable to wear. I bought it a year ago and never had a problem. The sound quality is good. The batteries last long. The range vs interference is great. Overall it is a well made product.

Cons: None so far.

Other Thoughts: The transmitter could be a bit slimmer.

5 out of 5 eggsUPDATE working perfectly now.

Pros: alright, so i posted about an hour ago, not sure how long ago the reviews will say it was, but at the time of writting it was an hour ago. anyways the problem i had was the headphones had way to much echoing and was like 5 octaves above normal... my problem was i had an online radio playing on my phone, into my computer, into my headphones... but straight from my phone, or computer it is so crisp its ridicules... better than my old $40 wired headphones...

Cons: wrote a bad review...
didnt buy them sooner... even though i bought them over black friday!
i dont have any friends?

Other Thoughts: worth it... you know, if you like audio...

sorry about the other review...

4 out of 5 eggsbass? and echo echo echo.....

Pros: cheap IMO <- just like the rest of this review
comfy, for about an hour with NVIDIA 3D glasses 2 or till your ears die without the glasses...
havent looked in a mirror to see if they are stylish yet, but is that really a factor when it comes to quality?...
easy set-up for those who have common sense... set mine up in 3 minutes... <-that's a guess...
the multi channel would be nice if i had multiple heads i guess, but seeing how i dont need it, i cant say much about it...

Cons: i cant hear any bass... like, at all... maybe its broken?-.-
i get a very small echo... but it is enough, that with no bass it makes me very very mad... <- neweggs rules wont let me describe how much it annoys me...
ive tried all 3 channels and going up and down the tuner... for quite awhile... no better... tried going into "playback devices" (win7) and see if it was just a brain fart or something... no fix... went into realtek HD audio manager to see if there was some type of bass boster/echo stopper... nope...

Other Thoughts: these would be perfect if:
-there was more bass, or less treble?
-if there wasnt an echo.

i bought these because it was a wireless headphones, and i have bad luck with wired headphones... always short them out... so i thought that these would, you know, work... so far... it would be better to buy $50 wired headphones every 2 months then to live with these... hopefully i can get some tech support in the A.M. and fix this problem... if i do. ill write a new post!

4 out of 5 eggsWorks

Pros: Crisp clear sound....once you get the sound device working properly.

Cons: Ease of use is not user friendly.

Other Thoughts: I had to play around with the amplifier in my bedroom to make it work properly...for a good 20 minutes all I heard was complete static with muffled audio from the video I was trying to watch....come to find out I had to use the setting of "2 CH" and not my surround settings such as "A-Deck"

Also had to turn the sound on my amplifier all the way up for it to transmit correctly.

Other than That a great buy.
