Not sure if I receive a defected item but the sound quality is very bad. Sound like those very cheap headphones from Walmart.

I am extremely disappointed with the sound quality of these headphones.  I purchased them directly from Verizon as I had a 20% discount.  For $99 retail price, I expected clear, crisp sound, and acceptable bass in addition to the smart and comfortable form of the headphones.  I will admit that $20 Ink'd/ Smokin earbuds from skull candy blew these jabra headphone speakers out of the water.  I went back to my original headphones that came with the iphone as they even sounded better.  You will not hear any bass, period, and the sound can be muddled as though you were trying to over power the speaker on your phone itself.  Hip Hop, EDM, and even Heavy Metal are unlistenable on these headphones.  They are comfortable to wear, they stay in place, but the sound quality just was not there for me.  I will return these to Verizon.

I have no idea how these got so many good reviews...  Sound quality is terrible.

I purchased these headphones last week. The sounds quality is good however the microphone quality is very poor. Everyone person I've spoken with since purchasing the headphones has said that they have trouble hearing me and that my voice fades in and out. Very disappointing as I like the sounds quality but will be forced to buy a different brand due to the poor microphone quality.

These are not near the sound quality I was looking for.  They produce static noise and will not turn on occasionally.

I had a set of these in hopes of replacing my aging 730s. I couldn't last even one song.

The was sound is flat and tinny compared. They're is really no other way I can explain it. These headphones failed at the one thing they are designed for which is music. I'm hoping they are simply defective.

The sound quality on these are AWFUL.  I'm sorry, I can't recommend this to anyone no matter how cheap it is.  There's very little bass, and any loudness in the headphone sounds piercing and awful.

They are very comfortable, but the sound quality is not satisfying at all.
I would not recommend them. I understand that they are <$20, but I gave them to a friend and kept using my Audio Technica ATH-M30.
Better go for the monoprice over-the-ear headphones:

These headphones have such poor audio quality you won't want to use them. I'm going to keep mine as an emergency backup and seek something better. The audio sounds muffled. Music lacks clarity even on the best produced recordings. There is a frequency spike around 1200Hz which will quickly give you ear fatigue. These phones can get pretty loud, and they may appear to sound better with the volume cranked, but unless you want to go deaf I would keep looking and pass on this "bargain" set.

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

These are not a good headset. Very low sound quality and output.  Tried listening to music thru computer and iPhone with the volume all the way up.  Sound is very faint and there is no punch to the bass and volume.  Would not recommend if you use them on these devices.

Sound quality not so good. The volume is the worse part, in the highest possible setting is still very low. Sending them back

and on top of the muffled sound, they are extremely uncomfortable to wear. After about an hour, my ears hurt and I had to take them off

So, I can't really recommend these

I purchased these based on high reviews. Unfortunately stopped working after 4 months. They will charge but won't turn on.

Also, the right headphone contains all the on/off and volume features which makes it heavier towards the front and tends to slide out of the ear when running or high impact exercise. They are loud headphones but they don't sound good and the bass is over the top.

Overall I can't recommend this headphone.

Not comfortable and not really usable sound quality either.  Skip these

I tried Beats by Dr Dre for a day. Then decided to order Sennheiser PCX 450. I tried them only for about 20 minutes and decided to return them. The sound of Sennheiser is so much inferior, I could not believe. The bass in Sennheiser does not exist. Also, there is vibrating sound when I turn my head towards my left arm. It's very bad when noise cancelling headphones create noise.

These headphones have good sound quality. The reason I am giving it 2 stars is they have already broke apart at the wire and earbud. I have had them for a little over a month and can't send them back.
