The headphones sound good, but after having them less than a year

The headphones sound good, but after having them less than a year, the screws that hold the left speaker in place are coming loose.  You cannot take it apart to tighten the screws.  I have to send the whole thing to Philips and hope they honor the warranty and don't give me any issues.  So, these sound good, but the build quality is not sturdy at all.  They will literally fall apart on you, right around the time warranty is up and you can't even fix them yourself.  Good luck.

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)

I bought these headphones about a year ago. they sound great and they are well designed. I just have a little complain. The end of the wire is completely worn down after a year I expected them to last longer.

I've had them less than 2 months and one of the earbuds already has no sound.

Ehh the headphones were ok while they lasted. After 4 months the Jack input went out on the headset. Nothing wrong with the wire (i tried it on a different pair) but they were good while they lasted.

As the title suggests, I've had these headphones for three years and I have actively used them for months at a time. The sound quality is decent, the build quality is of cheap plastic but the set is very. The pads have worn down quite a bit but they were very comfortable for the first year and a half or so from very frequent use. After a while you start to hear the plastic in the headphones move which gets incredibly annoying. When I got these they were about $20. If you're considering purchasing these for more than about $35, don't. They're very expensive on here right now, they're not worth it.

**Update**
Anker contacted me and offered to send me a new pair!
Of course I accepted, and am now enjoying the new pair!

First let me say that I like theses headphones, they sound (for the price) very good. the battery last about 5 hours, which for its size is great. And I've gotten good use out of them.
Here's my downside, I bought a pair in December (2016) and they just broke (worked of 3 so months).
First the volume rocker fell off a few weeks ago, but you know just throw some tape on it and it worked.
But then the left ear buds case separated, and tape won't fix that.
It might have just been my unit that was defective, I'm just disappointed because I did like them.

For cheap headphones playing mp3's over a Bluetooth connection these sound pretty good as long as you don't expect professional quality sound. The Bluetooth connection works well with my Win10 phone and they are comfortable when I wear them for hours at a time. Unfortunately after only a few months a small plastic piece inside the swivel of one of the earpieces broke and the earpiece is just dangling by the wires so they are useless to me now.

Hi

I bought this in March 2012. The headphones are awesome in performance. But the strength of wires connecting headphones is not good. So within few months , the wires are getting distached. I still have warranty for the headphones.

Please help me(Amazon.com) how to complain about this and get a replacement.

I tried calling senheiser but dint get any response. Very Bad Customer Service.

Thanks

These headphones deliever a balanced sound that is pretty good for headphones at this price range. I was satisfied with the product. I was disappointed with the fact that one of the ear buds failed after about four and half months. This ruins the listening experience altogether and leave little options other than to buy another pair. I expect headphones to last for at least a better part of a year. Other than the durability issue, I would recommend these headphones.

I initially bought these last year. These earphones are incredible, especially for someone like me who has little experience with earphones above the $100 range. Every song I listened to on these seemed new, and they just blew my mind. Hence, when I ended up losing them, it was devastating and listening to music just did not seem fun anymore. I was hesitant about buying them again, but when listening to cheaper earphones did not do the trick, I had to purchase them again, and I am in music heaven once again.

Edit - After roughly six to eight months of use, the earphones don't work like they used to. The volume is incredibly low and I don't know why. Since I don't live in the US, it will be hard to claim it in the warranty and it's disappointing that they stopped working so soon.

The good:
I have owned this particular pair of headphones for 6 months, and this model of headphones for a year and a half. The sound quality of these headphones is the best of any in-ear headphones I have ever used, so I use these daily for everything I possibly can. I will even use these instead of regular speakers when I have the option.

The good(or possibly the bad, depending on your opinion):
I have a reputation of being harsh on headphones, and these headphones lasted me almost twice as long as any other pair I have owned. I am on my 3rd pair, and I break these headphones almost consistently after 6 months of use. First, the right earbud becomes quieter and quieter, then finally it just completely fails. Thankfully they are so cheap that it almost doesn't even matter.

The bad:
The headphone jack doesn't fit in recessed headphone pugs

The sound is fantastic and in general, I love these headphones. However at just short of a year, they are all but impossible to charge. I plug them in and have to move the charger "plug" into the headphones around until the charge light goes on and then it only lasts 10-20 seconds. It's very frustrating. I do not use them near enough for these to be messing up already. So disappointed. I hope the people I recommended these to aren't going through the same thing.

If they aren't, they really are great in every other way. Sucks I won't be able to use mine for much longer. :/

I have owned these headphones for over a year, and I feel that I can give a relatively accurate review of them.

I'll start off with the good.
These headphones sound great! I listen to mostly electronic music, some rock and some pop, and it all sounded great in these cans. The Crystal Method, Daft Punk, Justice, all sound amazing, and I'm using a little sandisk sansa mp3 player. The Hesh do have a bit of what I can only describe as an echo, It is a very subtle effect and most of my friends can't tell. I actually like the effect, they sound "roomy". They have great bass, owing to the sealed design and 50mm drivers. I never noticed the bass distorting the mids or highs either, which I was impressed by. (disclaimer: I am by no means an audiophile, this is just my personal opinion)

I like the tight fit because I don't have to worry about jumping around and my headphones falling off. I did not find them to be uncomfortable though, I could use them for about 4 hours before it got uncomfortable. I use these walking back and forth to classes, and riding my bike, and they are great, but they are a bit awkward to wear around the neck, since the ear cups don't fold down they hit the bottom of my chin. I think these look great, I like the style and the fit, the headband is comfortable and solid. They do tend to creak as you move, it didn't bother me but my girlfriend couldn't stand it.

Now the bad.
I have gone through three pairs of these headphones, and I take good care of my things. The pressure these exert on your head is just too much for the plastic to handle. For me, they always break at the thin strip that slides into the headband, the headband adjuster. They just snap in half. I do not know a single person who has owned Hesh headphones for more than a couple months and NOT had them break in half. I saw a girl with a pair the other day, so I thought I would warn her that they were likely to break. She calmly informed me that this was in fact her fourth pair. Fortunately Skullcandy has a lifetime warranty on their products, so you can just ship them back for a few bucks and they will send you new ones, but is it really worth it? I cannot stand always knowing that my headphones will break in half in the near future. I get close to a pair of headphones, they go everywhere I go, and I have a special bond with them. If the Hesh didn't break constantly I would still be carrying them with me everywhere I go, but I can't fall in love with something I can't rely on.

I bought some Ultrasone HFI-550's earlier today and I can't wait to get them and fall in love with some new cans. When Skullcandy sends me my newest pair of Hesh I'm going to sell them and get out of this vicious cycle.

Some people don't seem to mind replacing them now and again, but for me it ruins the experience.

I hope this helped you make your decision, I really think it boils down to if you mind shipping them to Skullcandy to be replaced every so often, because you won't find a better headphone for anywhere near this price range.

One side of headphone stopped working in less than 1 year, no warranty available through Amazon.

I bought these directly from Monoprice a little over a year ago and I loved them when I first got them.  I use them for calls through my phone and computer, for gaming on my computer and for listening to music while I work.  More often than not, I do so using the included headphone cable.  After a few months, I noticed playback was cutting out on the left side when I was using the cable.  I found that I could continue to get regular audio if I backed the headphone jack out just a little bit, so I continued to use them like that.  For the first time in months, I tried listening to music via bluetooth and found that I could get no audio at all out of the right side.  The microphone also wasn't working.  No amount of changing settings or connecting to other devices seems to be able to fix this.  Since they still work as wired headphones (mostly) it's not a total loss.  The sound is good and they are fairly feature rich.  If you can get them on sale they're worth a try.  I just can't speak for their longevity.

These headphones are OK.  The sound quality, fit of the earbuds, and everything about them was fine.  Unfortunately, they've stopped working after 13 months of light/moderate usage.  They still connect to devices, but zero sound is produced.  I see an 18-month warranty period cited here on Amazon, but only a 12-month period on MPOW's site.  I've contacted MPOW customer service requesting warranty service, so we'll see how that goes.

UPDATE: As soon as the seller saw my less-than-favorable review, I received an email stating I was receiving a replacement pair.  The replacement pair is equally as decent as the first.
