To put the sound quality of these head phones into perspective, they sound worse than the standard head phones you get with your iPod.  That's how bad they are.  So what's good about them?

1. They are cheap. You can get them for around $65.
2. They do a pretty decent job of canceling noise.

Beware though, all noise canceling head phones color the sound/quality of your music in a negative way.  Its hard to describe exactly what they do to the music but its not a good thing.

Bottom line, if you really need some peace and quiet in a small package at a reasonable price then this may be for you.  If you are looking for some decent sound quality then look else where...

Really kinda surprised by this review as even at the price it is not a value as the sound is so bad. Skip on this.

returning them, sound quality poor for a $20 pair of speakers, especially w/ the hum.

Very bad sound quality. Honestly, I don't know why there are so many positive reviews about these, I had a bad experience! Sorry!!!

I probably shouldn't complain too much given the price of these headphones but they are the worst sounding things I've ever owned. I use them at work and as such I literally have them on the lowest volume setting possible but they still distort constantly. I'm just super let down with the terrible sound quality, on the plus side due to using them at such a low volume the battery life is much better than advertised. The box said they were rated for 4 hours of battery life (the description said much more than that or I wouldn't have bought them) but I'm actually consistently getting around 7 hours of horrible sounding music

They make sound, but the sound quality is sorely lacking. I installed them in the rear doors of my 2013 Ford F-150. I can't even hear the highs coming from these speakers, the lows are muddy and the sensitivity (88@1/W) is so low, my factory speakers are blowing these away. I have to set the fader to 2\3 rear to even hear them coming from the back. I wouldn't recommend these nor would I ever buy them again. I wish I could return them for a different pair. Very disappointed.

The sound of these in-ear are really not very good. I would not recommend these for the serious music listener. If anyone likes to listen to them, you can have mine.

I can't really complain considering the price, but having seen and heard them, I would not buy again. I won't go into specifics, but both the build quality and the sound are pretty bad. Definitely worth spending a few extra bucks to get something decent.

Alright value for the cost, but absolutely terrible sound quality

I received these as a gift and I've honestly tried to like them, but I can't.  There is a constant hiss in the background that can easily be heard when listening to quieter music and podcasts.  There is also an electrical interference noise that can be heard only in the right ear cup.  Additionally, when audio gets quiet enough, the speakers shut off with an audible popping sound - it's absolutely infuriating if listening to a track that fades in and out, or conversions with pauses (a podcast, for example).  I can't recommend these and unfortunately I can't exchange them since they were a gift - oh well.

Horrible sound quality, nicely constructed, descent features and fit but these are NOT for music. I tried them out in the quiet of night and compared them to my apple ear buds that came with my iphone 5 as reference and my ear buds sound 10 times better, and they're usually rated as average in sound. With these Jlabs  Bass and midrange are about the same, throw in some muffled highs and if you don't know the song it will take a while to figure out what it is, you can always crank up the volume but that will just hurt your ears.  I just think that for $50 i expected something at the very least acceptable...

I bought these as a replacement for a pair that I love and have had for about 10 years. And I have a HP computer, so I didn't think I could go wrong. I'm a pianist, so I really enjoy music. The sound from these is absolute garbage. I love the low-profile sub (usually they're massive), but that's about the only compliment I can give these. I won't listen to music from my computer anymore because the sound is so bad. Your money would definitely be better spent on a different pair.

The sound is good, acceptable bass; they're not the worst buds you could buy but I won't recommend them.  The volume gadget on the side is a little difficult/awkward to find while you're wearing them, and its location is not intuitive no matter how long I've been wearing them.  The BIGGEST DETRACTOR and enough to recommend NOT buying them are the ear cushions...virtually every occasion I use this set, I'm losing one or both of the cushions.  An action as simple as putting the buds in your pocket and later taking them out is enough to yank one of those suckers off without realizing it, and whammy, you're without a soft bud (or both of them) before your run and now you're jamming irritating and hard plastic sticks in your ear until you get home and replace them.  Based not the cost of purchasing replacement cushions, you're better off putting more money into a more expensive, reliable set of ear buds.  It's disappointing because I'm pleased with the audio sounds of this set.
