They sound great and are very comfortable but the right ear bud tends to crap out/quit working after about a year which is why I've bought 3 so far.

They truly do have great sound if you are fond of the lows freq. in audio. Only complaint I have is I bought mine May 28, 2008 and noticed yesterday Aug 20, 2008 the left bud stopped working. That's not even 3 months and I have been taking extra care with them.

I bought these earbuds about 3 months ago and I must say i was very impressed with the sound quality.  The sound is very clear while maintaining a beautiful balance of bass; however  the right earbud has now stopped working which took me my surprise considering that the earbuds are pretty much new.  I do think i purchased a warranty of some type which I will utilizing.

I was very satisfied w these earbuds until last week when the right earplug stopped working. I had only had them for two months. Unfortunately for me, I guess, Amazon will not allow me to return them. I will contact LG to see if they will allow me to send them back for a replacement.

I'll echo the other reviewers regarding the sound quality of these. They sound PHENOMENAL! And they served me fairly well for at least 9 months.
This morning marked the end unfortunately. Turned on but sound would only play from the right ear piece.
They weren't abused, used harshly or even used in wet weather.
Even if you decide not to heed my warning and proceed with purchase, know these few things:
-If you have small ears, they will NOT hang as depicted in the photos. The vertical ear bar is not adjustable, it's just flexy rubber. No way to pinch it tight to hold in place on your ears. The interchangeable plugs do not compensate because the headset is just a tad too heavy to resist the effects of gravity and friction.

The ear bud fits nicely in my ear and once I found the right spot it is fairly comfy . The sound is great unless you are under or near high voltage power lines, then it has a major hum. Maybe it Is just mine. I haven't gotten far enough away to test the range, I will post more about that later.

I received my item rather quickly and loved the amazing bass and sound quality. They fit perfectly and a lot better than the standard headphone. However after a couple weeks of use, I noticed that the right ear piece wasn't producing any sound due to a short in the wire near the headphone connector piece.

I can understand this happening occasionally and would rate this 5 starts if it wasn't for receiving a defective item. I am looking forward to receiving my replacement item here soon.

These headphones sound amazing but with any movement of your head or slight tug on the cord the right side of the headphone goes silent. This doesn't happen all the time but enough to get really annoying.

Probably the best pair I've ever had but unfortunately the right ear bud came off within only the couple of months I've had them.

When I purchased these 4 months ago, they were rated at around 4.8/5 stars.  Today, the right ear speaker went out.  Amazon now has the product listed at 3.8/5 stars with numerous reviews stating the same issue.  This is unfortunate because they sounded great, were comfortable, and appeared to have a solid build quality.  I am contacting Sentey now and hopefully they will work with me.  The other reviews seem to be a bit hit or miss with Sentey's customer support.

I bought a pair of these and they sounded great.  But after only 4 weeks the right bud stopped working completely.  I double checked then to make sure they were plugged in all the way.  They were.  I switched ears to make sure I wasn't suddenly deaf in one ear.  I wasn't.  A true dissappointment.

After breaking them in, I enjoyed the full sound of these ear buds for about 5 months before the left bud stopped working.  It's been 11 months now and the other bud is starting to go out.  Something else I found interesting was how they label the left and right buds.  There is a tiny "L" on the rubber connector on the left bud, but I didn't notice that until like a month ago.

EDIT: After contacting customer service, the issue was very quickly resolved and a new pair has been sent out.  Thanks, JLab!

The sound on these is the best I've found in this price range. I've been extremely happy with them in that regard.

The down side is  that the pair of "JBuds Hi-Fi Noise-Reducing Ear Buds" and the pair of "Coby CVE92 Isolation Stereo Earphones" I've had both failed in one ear in about 3-4 months and in the other ear around 2-3 months later.

I'm assuming this is the same pair of headphone just branded differently.

Since they are so cheap (~10-15 bucks at my time of purchase) they are probably worth the money especially if you a kind to them. I use them daily at work and wind up the cord after each use. Also, I use them when I'm running.

It would easily be a 5 star rating even if I got a year out of these guys.

Great sound but the left stopped after a year, bought another pair and the same thing happened after a year (about 60 hrs of use)

These headphones are truly 5.1 and they are comfortable. As a matter of fact, these are the most comfortable headphones I have ever owed. The sound is great most of the time. As I stated, most of the time. There seems to be one major flaw and that would be connectivity. The first set I bought failed right out of the box. The left side kept cutting in and out. Sometimes the center speaker would not work and then sometimes the right front. So, I sent them back for an exchange. Amazon was terrific on this. I got my new set within a few days. The second set did exactly like the first set so, I thought what are the chances of two sets having identical problems. As I searched for the cause I finally discovered that the problem lies in the splitter that comes with these headphones. If you plug this set directly into your sound card they are perfect in every way. But, if you do as I did and plug them into the splitter so you can still plug in your external speakers then the trouble starts. The plugs seem to have bad connections. Periodically I loose sound in one are more speakers. When this happens I start unplugging and replugging the jacks at the splitter (headphone side). This takes care of the problem until you go to use them again a day are two later and then you have to repeat the process. This is very annoying. Had I not gotten these at a cheap price I would be steaming over this. But, for the money saved I can live with the problem. Besides, I am sure that when I get over being lazy I can make my own splitter out of quality plugs and cable from Radio Shack and all will be good. The headphones themselves are phenomenal. The fault is in the splitter.

The sound is great! But as soon as I got sweaty my right one kept falling out of my ear. The left one did to, but not like the right one..????
