4 out of 5 eggsGreat sound

Pros: Great sound (especially after a burn-in period)
Very comfortable
I like the orange cord

Cons: None

Other Thoughts: I picked these up on a Flash deal for $35 and was blown away at the quality. I am in mourning because the left side just died on me and I hate the idea of having to replace them. I would recommend these to anyone looking for comfortable earbuds with big sound.

4 out of 5 eggsGave as a gift...

Pros: Good sound. Close to my Bose after break in. I like the longer right wire. Snug fit. Blocks most noise. 27 buck sale at buy dot com.

Cons: Cord tangles easily. Plastic sheathing on right wire has streched and is starting to tear. I don't think they'll last much longer.

Other Thoughts: I bought these as a gift for my yoga freak girl christmas 2011 and she has been happy with them. She was used to the 5 dollar kind that you get from TJMaxx so when she heard these she was a convert. Maybe it's my imagination but I believe these started sounding even better after I broke them in for a while. I just plugged them into my computer, half volume and looped a bunch of music for 48 hours.

3 out of 5 eggs

Pros: * I like how the right cord is longer than the left. This was done for a reason as the cord goes behind your neck, resting remaining length of cord on your left shoulder. This support keeps the buds in your ears better.

* These headphones sounded amazing for the first eight months. I could totally call them "noise isolating," and they sounded every bit as good as my speaker and subwoofer combo. They in fact made my speakers obsolete, and I only used those for movies.

Cons: * After eight months, which is to say a few days ago, they suddenly went bad. As the reviewer just previous to me points out, the volume is incredibly low. Where I was using only 40% to blow my ears off, 100% is hardly livable, and this of course reduces the quality by causing grainy sounds.

Other Thoughts: * If they weren't discontinued, I would recommend these. I know it's only some people that get defective products, and I know that I'm just one of the unlucky ones. If I weren't looking for a microphone, I would send them in for manufacturer repair as they're still under warranty, but I decided to order a headset.

1 out of 5 eggsJunk - just junk

Pros: None

Cons: Terrible. Worked for a couple of days and then they lost 90% of their volume and fidelity. Now useless. 0-for-2 with Sennheiser this year. Now I'm done with them forever. Just awful quality.

Other Thoughts: See my review for the CX200 (the other piece of junk I got from Sennheiser this year)

2 out of 5 eggsDiscontinued for a reason

Pros: These ear buds are very well suited for working out or for being worn when active. The clip that the come with is very handy for keeping them in that perfect position so they don't pull out of your ears or snag on your shirt.

Cons: Sound quality was lacking. At their original price point I was expecting a better product, however, I was wrong. More annoyingly, though, the 3.5mm jack seems to be defective as its too long to go into any port. It sticks out too far and you're left with a cracking, popping sound at all times.
The ear buds weren't comfortable for me in any of the sized provided. This was a shame since this is probably the reason why I can't vouch for these ear-buds as being noise canceling.

Other Thoughts: I may have just gotten a dud, but I can't recommend these ear buds based on their sound quality or their fit. After a few months of owning them I am looking for a new pair of ear buds since the defective jack on these is now separating.

5 out of 5 eggs

Pros: Awesome adjustable fit. Stays in place when jogging, etc. Sound quality is very good from thumping tight bass to ample mids to silky highs. Yellow color makes them easy to find.

Cons: None

Other Thoughts: If only they made a cord that would not tangle!

5 out of 5 eggsFor the $, Amazing!

Pros: Tried them out while doing a weight and cardio workout, couldn't be happier. Amazing sound quality, and to think that those stupid white headphones that Appl3 gives you were good...tisk.

Cons: I don't like how one cord is longer than the other, but I hear that it has its perks. It will take some getting used to.

Other Thoughts: The packaging really sucks. Took me a while with some scissors and when I finally got to the goods, the ear plugs went flying halfway across the room.

4 out of 5 eggsAmazing earphones!!!!

Pros: -Well the obvious one, $19.99 with free shipping.
-They're very comfortable and they actually block out environmental noise.
I initially bought these for my workout sessions, now, I just use it all the time.

Cons: - Almost broke a knife trying to take the earphones out of the package.
- Needs more bass.

Other Thoughts: Shoulda bought 2 at the time because my wife just got http://www.newegg.com/Product/Product.aspx?Item=N82E16826138070

5 out of 5 eggsThese are GREAT!

Pros: Very impressed with these. They really do block out noise. The orange cord is light weight and nice quality, in fact the entire thing is very nice quality. The ear buds are very comfortable as well. This is the best pair of earphones I've ever used.

Cons: The packaging is incredibly stupid. First I gave them to my girlfriend, after she broke a nail she sobbingly handed them back to me. Then I tried a pair of scissors, which failed miserably. Then I tried clawing at it myself, which also failed. I'm not sure how we got it open but we both were almost too exhausted then to even try them. But then we tried them and it was like.. WOW! Well worth the wait, I guess I could compare it to eating a banana, with a cast iron peel. It's yummy on the inside but really hard to get to.

Other Thoughts: I bought them for my girlfriend, she hates ear buds but they were orange, her favorite color, and matched her little ipod shuffle thingy which is also orange. She couldn't believe how comfy they were and they fit perfectly. I was also amazed at the performance quality, it's just a complete package of niceness. We also purchased it during a shellshocker so the price was extremely low, but it's still worth the retail price in my opinion.

5 out of 5 eggsgreat little headphones

Pros: These headphones have a great range, The highs are crisp, the lows are warm, and the bass is tight. The bass does not sound muddy or over power the rest of the sound like beats do. Comfortable you forget they are even there, and they have never once fallen out of my ears like apple and skullcandy headphones.

Cons: The case was cheap so I dumped that. Also would have been nice if there was a volume bar or microphone.

Other Thoughts: Buy them they are amazing!!
