Great sound, poor comfort
934588
For less than $25 and with so many positive reviews, I decided to pick these up to use while working at home.

My initial impression was that these sounded great.  I was hearing parts of songs I'd never noticed before.  Bass was good and every song/movie sounded fantastic.

However, after about 20 minutes of use my ears started to hurt.  I have a pretty averaged sized head and averaged sized ears but these headphones really made my ears sore.  My girlfriend found the same to be true as well although it took her longer to feel an discomfort.  So I gave these a three, what's the point of great sound if I can't stand to have these on my head.  Somewhat subjective I know but just something to keep in mind.

Sound quality is great, but after a while makes my ears hurt.

Good sound, and well made - uncomfortable though, they clamp my ears pretty tightly and are not pleasant to wear for much longer than a few minutes sadly.

The sound out of these is superb !
On the other hand they are not as isolating as I would have liked (they are not firm enough to produce a good seal around the ear, for many people this is a plus in terms of comfort)

Bought these from best buy and absolutely  love the sound. Used for music, movies, school videos and have not had sound quality this good in other head phones. HOWEVER...these are on ear and hurt like heck after an hour of using. I had to return them as they were too uncomfortable. I am going to buy the over the ear instead from Amazon.

I'll make this pretty quick since there are so many reviews here to read.

PRO- Absolutely phenomenal sound.  I am not an audiophile but every part of the sound is spectacular in my opinion.  Cannot rave enough about the sound quality.

CON- They can be quite uncomfortable.  If you are just going to be sitting at a computer wearing these, they might work for you (although be weary after an hour or two they can start to hurt).  If you are going to be active I would not recommend.

All in all I'm not disappointed in these headphones but if I had to redo this purchase I'd probably go with something comparable that had better comfort.

The sound quality is really great for the price, but that are just plain uncomfortable to wear for a long duration.

They sit on my ears and exert enough pressure that they cause pain after an hour or two. On top of that they really don't seal against my ears very well and let in a lot of outside noise.

The build quality isn't great but they feel sturdy enough for light to moderate use.

I don't have any complaints about the sound, they sound good.  Only problem is that they become uncomfortable to wear after about a half hour.  The ear cups are too small and the fit is tight, so your ears start hurting as they are being mashed against your head.  I've got a pretty average head and ears, so unless you have little ears or not using these for more than 30min at a time, I'd go for another pair.

These headphones from Bose sound great, no doubt about that, but between these and the Sony in ears, is about fit and comfort and the Sony fit better that the Bose.  i spent a $100 bucks on these and they barely fit in my ear. I've tried the small and medium buds and they don't fit in my ear at all because of my small ear canals.  The design is great, it there choice of earbuds is the problem, if they had a better fit and stay stable in your ear while moving around, these will be a keeper, but looks like I'll be taking these back to Best Buy for an exchange or a refund and buy some Sony ones again.

Range is amazing. Sound quality is good, but the comfort is lacking. Ears hurt after a few hours of wearing.

Nice sound, great range, poor fitting.  Prone to slide completely off of head, if you are in the habit of being active around the house while using your headphones.  They may fit a bit better with a better set of foam ear pads, though I have yet to spring for them.  The biggest issue is the fading, hissing, static, and sudden squealing that happens if the input source goes silent.  Really annoying.

The sound is great. The only problem is I can't wear them for a long period of time. They are not comfortable to wear for a long period of time.

I "show roomed" these headphones at my local electronics store quite a bit before I decided to make the plunge and purchase them. To the point: these headphones sound awesome! The sound quality is above and beyond what I expected. Especially considering the price I paid for them (<$100).

BUT ... they are not the most comfortable headphones. Truth be told, they make my ears hurt (not my eardrums) and somewhat tender after more than 30 minutes of wearing them. Ironically, when I was testing them at the electronics store I wore them for about 10-15 minutes on at least 4 separate occasions. No pain at all just wonderful sound. That was a key factor in why I decided to purchase them. But with my actual usage at home I have to limit it to less than 30 minutes per session. O well. Caveat emptor.

Sound is surprisingly good.  VERY easy to clean.  Pretty durable too.  The comfort is terrible at least for my head/ears.  Can wear for 10-20 minutes, but that's it.

They sound so amazing but I wish it was more comfortable.
It clams my ears so tightly, after 20 min it starts hurting.
More padding would be great.

The sound is really good just wish they were more comfortable to wear or smaller for my ears.

These sound excellent out of the box, but I think they fit a bit too tight.  The ear-cups are too big to be supra-aural but too small to be circumaural, making them just the slightest bit uncomfortable for my ears.  Additionally, I wear glasses, and the headphones push against my head a bit too much for them to be comfortable.  Mind you, this is all after about an hour or so of use.

They are smaller than I anticipated, but still not very portable.

Pros:
-Sound great
-Long cord (pro for me, maybe not for others)
-Comfortable for short periods of time

Cons:
-UGLY; you will look strange wearing these
-Uncomfortable after a relatively short time
-Not very portable
