My Experience With The Earphones And Customer Service. (BTW it has warranty on it!)
597791
These earphones are fantastic.  It does a great job at blocking all outside sound, and I must mention they do come with warranty.  I accidentally damaged the jack of the earphones while on a plane, and because of this only one side of the earphone worked.  After my travels, I saw that they emailed me saying it comes with a warranty.  I emailed them, and informed them of how I accidentally damaged them.  A couple days later, they replied to me saying that they are sorry to hear what happened, and that they will send in a new one for me.  The earphones are such great quality, and I am happy to say that their customer service is just as great.  The cables of the earphones are super durable, and you can tell just by touching them.  So if you're looking for some earphones that will last a long time, then get these.  Especially since they come with warranty.

Hi there. This is a great product. Too great of a product that I would recommend it. But unfortunately, the headphones I have they had a short life span. At least the left earphone. But other than that is all great.

Hope I get a warranty to fix the issue. :)

I owned these for roughly a year and a half, before one side completely stopped working. The endured only light/occasional use, and 95% of the time they lived safely in my top desk drawer at work, so I don't recommend them is you are looking for something durable, or that will last. I have other earbuds that were much cheaper, and of similar sound quality that have lasted much longer.  However, they are comfortable and light and the cord is easy to untangle. The wood looks and feels nice and the built in microphone and pause button on the cord are great features. The sound quality was fine, although to call them "noise cancelling" is a bit of a stretch.

UPDATE:

This company obviously greatly cares about its customers. After emailing them regarding one earbud not working after 1.5 years of very light use, they are shipping me a replacement pair (note: my pair was beyond the 1 year warranty). Their customer service was very polite and quick to respond to my emails.  I would absolutely recommend buying these headphones to anyone!

About a year and a half ago, I decided to pick up a pair of these from BestBuy just to try them out. I'll admit that they DO sound really good, but since I bought my first pair a year and a half ago, I have gone through 3 pairs of these. Oh, and I do treat my headphones good. I make sure not to pull on the cord, and I put them in the included case whenever they're not in use. However, I have still managed to go through 3 pairs somehow. The persisting problem for me has been that one of the two earbuds will start to produce a crackling noise, and then die. This might just be my experience with them, but it has happened 3 times in a row, so I don't think it is mere coincidence. I just thought I would put this up to warn any potential buyers. Hope this helps!

I got the headphones may 2nd, and the right speaker went out June 20th. While they lasted they were incredible, and probably my favourite headphones I've ever had, despite some popping in the audio and now the right speaker not working, hopefully it's covered by my 3 year warranty I took out, and after a year if I do get it fixed/a second one I'll update this review.

Just figured I'd let everyone know that it broke so quickly and easily despite me being very careful with it

Found the sound to be quite clear after the burn in recommended by JLab. I certainly aint no audio expert but I do enjoy a variety of genres/styles and to me the treble was really distinct (i enjoy hearing the sounds of cymbals and the like,) don't care for base, and the high's of some of the musical symphonies were gorgeous. I also found the vocals on some tracks to be extremely clear. -I've been very satisfied with the quality of such low priced ear buds - definitely recommending to friends and family.

I am also very satisfied with the quality of JLab Audio's customer service. I have had the ear casing from one of my ear buds dis-attach itself from the housing and JLab's simple warranty steps on their website was seamless - even letting me pick out a different color in the process! (I'm pointing this out because I read some negative reviews on their customer service on various models of the J's series, and have to disagree with the experiences of others.)

Update April 21,2013

Issue with no sound in one of the earbuds within 2 months.

Unfortunately I can't vouch for the durability of these earphones, after having a problem with one of the ear-bud's sound quitting on me app. a month and a half after I bought them(after no special occasion - wasn't yanked or pulled or drowned) I went through the warranty process and received a new pair three weeks later(one week to send it to repair center, 2 weeks - 10 business days - to process and then ship out). I was very grateful till the same thing happened to the pair I had just received as the warranty exchange. One of the sides just quit, I found it hard to believe being that that was the exact reason I had returned my previous pair. OK maybe 2 pairs were defective- my bad luck. Went online,filled out the warranty exchange and sent them back, after waiting three weeks, I received a new pair.
2/3 weeks later one of the sides conked out on me randomly again. Now sometimes I get lucky and am able to enjoy music in both ears, other times I have to settle for half the audio experience!

I am tired of packing up airbuds and shipping them out, then waiting for Jlab to process and ship them out via snail mail (as I said it takes about 3 weeks).

I'm going to try out another company with a good warranty that you hopefully don't have to  test as often as I have done with Jlab.

I believe it's a gamble with them, the sound is pretty good (for an the uninitiated/ novice -like me)however you might not get much use out of them,By contrast my J3's have lasted for 6 months with heavy usage and I love them, though they are slightly bulkier in the ear which is why I  went for the J5's rounder, slimmer design. In my experience, it has taught me that "new" does not equal better.

**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.

UPDATED to 3 stars following impressive warranty service.  JBuds responded to this review with a reminder that these were under warranty and an offer to replace them.  I supplied my info and replacements were shipped immediately.  I'll use them now and update again after several months of service to see how they hold up.
ORIGINAL review: After a few months of *extremely* light use (maybe a couple of hours per week at most), these things died:  no sound first from one, then from both of the earbuds.  Apparently, there are serious design flaws.  I don't know what to seek out as an alternative -- I'm such a light user of earphones, in fact, that I haven't bothered to replace them -- but I would say AVOID these.  Horrible experience.

I received my beats as a gift from a friend; and initially noted that these were an improvement over my apple earbuds. They also are fantastically tangle free (most of the time).  Bass is a little deep and less crisp but overall pretty good (I'm by no means an audiophile, just an average music listener).

I've had them a little over 4 months now with daily use, I went on a run. At one point during my run the left earbud came lose and fell out. Thinking nothing of it I went to out it back in to find the small jolt of it falling out of my ear had separated it from the microphone base.

So no problem I have a warranty on it: I'm sure they'll replace it; however after speaking to their customer service (very helpful people overall) I was told that "this is an atypical thing to happen so warranty may not cover it"; and that I'd likely have to pay a $60 fee to repair it.

Overall had a great 4 month run with them but Very disappointed in the craftsmanship and also the 'warranty'.

The earphones died after 4 or 5 uses by my 4 year old son who really liked them! Sorry for writing this so late but I wanted to let anyone buying these know that there is NO warranty and the return window closes fairly quickly too so be careful while buying. I would at least have liked to have a warranty return by the manufacturer but there seems no way to do that.

I got these as a gift a short while ago.  Be aware that their warranty isn't like a normal policy.  First, you have to request permission to register the product for the warranty.  They say on their website that they'll email you after they decide whether you get the warranty.  I did so back in June and still haven't received any confirmation (including after emailing customer service twice).

This wouldn't be a huge issue except that the headphones are unusually fragile.  I made it a point to use great care with them (always using the carrying case, being gentle when adjusting the headband, etc.), but they still snapped in half on me.

Please keep this in mind when considering these headphones.  My headaches with customer service are pretty much the only things keeping my review lower than 5 stars.

I ordered these back in June.  They worked really well for a while and they have good sound volume.  A few months in, the skip songs and pause button stopped working. Everything else worked just fine so I still used them.  It was "too late" to get a replacement through Amazon, but the seller had a one year warranty on them. I contacted them and they shipped me a new pair right away.  I would definitely recommend the headphones.

First set: Mine wasn't able to turn on within a week of the purchase. The fit was small and comfortable and the sound quality was adequate for the price, but I had to return because it broke so quickly! I'm not sure if I can trust my replacement purchase to function if I bought it again.

Second Set: after my two-star review, Axgio contacted me and sent me a new earbud stating I got a defect. I've had it for two months now and I haven't had a problem with this one. Thanks for the replacement!
Note: they did not offer a replacement product after I returned the first one. Only after giving a low rating was I contacted about getting a new earbud. A little disappointed at the inconsistency in customer service. Otherwise, the product is well worth the price.

I bought these headphones a year ago and they've broken two times since.  Thankfully they're under warranty, but it's a huge hassle to send them back.  I'd recommend the Bose headphones over these, I've had them for 6 months with no issues.

Update October: The replaced earphones stopped working again with the same problem. It seems they have a short life span.

Update March: Was replaced
One side stopped working after 6 months

Quick update to this review: without specifically contacting the manufacturer or anything, to my surprise a brand new pair was sent to my home, with an apology letter. That's some killer customer service!  For now, I'm leaving the review as 2 star, as I did experience the same basic quality issues with 2 separate pair; however, 6 months from now I expect to come back here and give an update as to how they're doing quality-wise (6-months seemed to be the cut-off of when the most gently-cared for pair gave out).
----------------

These have ok sound quality, never worked well for calls (person could never hear my voice, though I heard them fine). The main problem is long-term quality: they just don't last. This is my 2nd pair in less than a year, and both of them, after 3-6 months, one of the sides stopped working. My first set took 3 months, these have worked almost 6 months (likely b/c I treated them much more delicately).

I used them every workday, on my 15-minute walk to/from work, and on other occasional times. They don't block a lot of outside sound out, which depending on your usage is good or bad (good for me b/c I want to hear traffic around me).

They worked fine this morning, and I just put them on - and no sound on the left. For a short time I could wiggle the earphone around a bit, or pull it this way & that and would get some sound, but as soon as I let go - no more left sound.

Too bad, really - these otherwise are awesome - love volume control, love the pause button, love the skip/go back -- and easy to pair. Unfortunately, they just don't hold up over time.

I'll be now shopping for a higher quality wireless pair that will last me a few years, rather than a few months.

The headphones get plenty loud enough for me, and (with the proper sized ear tips in) don't leak much sound. I received my pair three days ago and the only complaint I really have (besides the difficulty in changing some of the eartips) is that the bluetooth cuts out once I put the phone in one of my pockets and is intermittent. Based on the other reviews I've seen here, Mpow seems to have excellent customer service.

I've only had a handful of times where I've had the time to use these earphones, but I'll give it a few more days and contact them if I'm still having problems.

Edit: On November 19th 2016 I was contacted by Mpow's Customer Service Department who after giving me some options of headphones,  offered to send me the Cheetah 2 as a replacement. Ms. Irene has been very understanding and I'll let you all know how the new headphones are when they arrive.

Edit On November 25th 2015, one day after Thanksgiving my brand new Cheetah 2's arrived free of charge. https://www.amazon.com/Mpow-Nano-coating-Headphones-Sweatproof-Calling-Black/dp/B0171F4SIQ , for me they are less comfortable but won't budge once they are in your ear. The Bluetooth cuts out only with the most strenuous of movement, and it is nowhere near as bad as in the Magneto earphones. I can only get the earphones to cut out if my phone is in my pocket and I'm bending down on one knee - maybe it's somethign in the fabric.

I'm still reserving full judgement until I get some miles on them when I go walking (which will be in my next update).  So far though, I am greatly pleased with the lengths Mpow will go to ensure that their customers get a quality product from them.

Edit December 28th, 2016, I finally went on that walk. 2 hours and 40 minutes later I still had plenty of battery, the earphones didn't budge and the sweat didn't bother them in the least. However, they do cut in and out when I was walking. I tried holding my phone in my hand as I walked and I still had the same problem. When I held my phone closer to me myself and didn't move my hand the connection stopped cutting out.

Besides the cutting out every other second or so (unless I moved the phone closer to my head/the headphones), I am satisfied with these headphones for their listed price.
