They are great while they last!!! Just like all the other reviews... they have great sound with great bass but hey only lasted two months.  I took great care of them.. but i started hearing a clicking in the left (microphone/volume control) ear bud, and a day or two later the left side stopped working.  I hope they address and fix this problem because i want these to work because hey sound so good.  WHILE THEY ACTUALLY WORK.

They are amazing. They last around 2 to 3 months. Totally worth it.

In the last year I have had 2 pairs of these headphones. The first pair lasted for 7 months before it stopped working in one ear, and the second only lasted 3 months. Luckily skullcandy offers a repair service where you send in the earphones to be repaired or get a cupon for a new pair. The sound quality and comfort are good, I just wish they would last longer under heavy use.

.... as long as they worked I was very happy.  Superb sound across the entire audio spectrum.  Very comfortable.  After 8 month of very gentle use one earpiece stopped working.  This now is my second set.  Bought a pair of the ms01 before.  The only lastet little over 3 month.

Hey Thinksound, there gotta be something wrong with your built quality.  I also own a pair of the On 1 which I love, but sometimes they are too bulky to carry around.  I believe should be due a free pair now!! What do you think?

For the price I'd like them to last longer than a few months, I'd say I added these around November of 14 and they have both been burned out since May. They were very bright and excellent before they went out though.

I bought these Nov 3, 2016 so it has not even been a year, they worked great until last week when the right ear side stopped working and now I find my self having to buy another pair from another brand. I am only writing this review because if you think they will last a long time I am sorry but they won't

Fantastic while they lasted but they shorted themselves out after maybe 2 or 3 weeks and I can't fix them now. Kinda sucks, but at like $10, I'm gonna buy more.

They sound and work great for the first 4 months. Then the left ear bud stopped working. I have two pairs and the same thing happened to both. I have email company and no one has replied! I will complain next to bbb

As you will find with many of the other reviews, these are fantastic headphones, but only for a short period of time. I have bought these several times for the fact that they put out some of the best sound for earbuds at this price, but they always fail. I have used the most recent pair for roughly three months. They worked great for that time, until this week. They are now putting out terrible sound which is scratchy and quiet. I have continued to be a customer in hopes that they would hold up, but I have an inkling this will be my last pair. Im open to suggestions for where I should transition to for similar sound quality and affordability.

These actually have pretty good sounds and I use them everyday at the gym to work out.  The problem is that I have had two pairs and they only last about 12 to 14 months before they stem inside the foam rubber breaks.  Today I went to put them on my head and with no force at all they just snapped.  This is the second time this has happened to me with these both in the SAME SPOT with absolutely no force.  They just wear out in a matter of a year.  If you are looking to wear something once or twice a week, they should last a couple years.  If you are looking to wear these on a daily basis, I don't recommend them at all.  If this break had happened to me once, I would say it was a fluke but both pairs I purchased broke at 12 months and 14 months in the same spot with no force at all.  I'd add a photo but they broke in the same spot as others have posted so really no need too.

The sound is great (very clear, the bassline is natural), noise reduction is perfect, very comfortable. I tried a few brands but this one is the best so far for the price! I used them for every day and running\exercising (they don't fall out). Why the 3* you ask? Well, today my SECOND pair is going to the bin. The ear buds extremely fragile and brake very easily. The first pair made it to 4 months and then the left earbud stopped working. The second pair held it for 3 months then the right bud just fell off!

They are very good while they last.  They fit well and are plenty warm up here in Alaska. However they do not last. This is now my 3rd pair, and I have yet to find some that last a season of cutting firewood for my cabin and a few chores outside.

Headphones are a great design and stay put while running.  I really enjoyed them...while they worked.  Their useful life is very disappointing.  I had mine for 16 months and then they died.  I have a friend who has burned through two pair, each with about the same useful life.  Further, warranty is no help because it is only for 12 months.  For a high quality product, I would expect better.

They deliver great noise canceling and sound quality...for a while. Then they break. Sure as anything, they break. If you wear them a lot (and I travel subways, so I do), eventually the part that connects the ear cans to the head band will wear out the whole unit will break off. Usually this occurs with 3-6 months of active use. I would pay more for these if they were more durably made, but no. Wish I could recommend them unreservedly but I can't.

I love these earphones!  They are comfortable, fit well worth a nice range of size buds to allow the best fit. Just get used to the in ear feel and they're excellent. Great dynamic sound range, clear crisp highs, rich warm lows. The mic does an excellent job of picking up voice and limiting excess noise from being picked up.

I have used several of these over several years. The only negative is they never last more than 4 or 5 months before a wire frays near the connector pin or the ear buds. I think I use mine heavily. If I'm on a call I'm on the hands-free for it, plus music on the phone speaker is not so great. But, even with that usage I take care to not wrap them around the phone or stress the wires with unnecessary stress, I want them to last longer!  I know they're an under $20 expense, but DAYAM! three or four pair a year adds up!!

I absolutely loved these earbuds when I got them. I use them at work, and they're so pretty. After about six months the right earbud stopped working, which I decided was fine since I only put one in anyway. But now (nine months from purchase) every once in a while they give me a little shock when I'm moving around. I'm not sure if it's the static from the cord or what, but I draw the line at little shocks! Great while they lasted.
