KOSS SPARKPLUG 3.5mm Connector Canal Portable Stereophone

Pros: Cheap. Decent sound quality.

Cons: They're pretty bulky. The cushion is soft, but the main ear piece rests on my ears and they hurt after a while.

Other Thoughts: Clean your ears before use. The materials used for the cushion is hard to clean. - It tends to absorb and cannot be wiped easily. I wonder where I get a replacemen cusion...Haha.

Pros: Sound great, work great, no noticable difference in comfort levels between these and any other in ear headphones. CHEAP.

Cons: Little rubber things do get kinda nasty, i clean mine with some rubbing alcohol to get ear wax smell off them.

Pros: Best bass I've heard in an ear bud. Cushions work like ear plugs, so they block out the world.

Cons: Poor construction. Foam cushions either dry out too quickly, or ooze greasy substance. Thin wire bends easily and possibly breaks inside. Blocks out the work, which simultaneously enhances gum-chewing, noise through vibrations, etc....

Other Thoughts: I had bought these twice, because I really enjoyed the sound (and they're cheap), but they don't last very long. Maybe got 3 months out of them each time. The wire always breaks internally, so you lose an ear- among other problems.

Pros: Memory foam works very well, Sound quality is unexpectedly high from such a cheap item, Product is durable, I have been mashing these into bags and into my pockets without a second though and yet, they are still in excellent condition. Cord is strong enough to be hastily and forcibly untangled without tearing the cords or ripping anything apart. Incredibly comfortable compared to over the head style headphones that I have been using my entire life, I don't even feel them in my ears anymore. I can have them in my ears for an entire day and the only thing painful about them, is when I take them off and am overtaken by suddenly being able to hear everything around me. You don't need high volume to block out all surrounding sounds, even a room full of people yelling can be dead silent to you while listening to a violin. The bass while unnoticeable when I first started to use them, is very powerful, since the bass only has to hit your eardrum and not shake your whole head.

Cons: The memory foam can get oily and dead skin flakes can show up on it. Other people will not want to use them because of this. movements in the cord are audible but not moreso than any other headphones I have ever used. having the earplugs accidentally pulled from your ear is always painful, as a rush of sound you where not expecting overwhelms you. You can't hear much outside of the headphones when using them, so using them at LAN parties or when talking to other people is hard to do.
After about 5 months the memory foam becomes stiff, and loses it's "memory" feel, fortunately it comes with backup foams. It can be hard to get the memory foam backups onto the headphones.

Other Thoughts: I have had these for 9 months so far, and have been using them for upwards of 6+ hours per day at a minimum. the sound quality is still very much high, the cord is in perfect shape and has not degraded at all. I do hope that I can get a new pair of memory foams from KOSS's lifetime warranty they advertise on their site, although I'd have to send them 6 or 7$ along with the product to them for that to work.

Pros: Price.

Cons: Don't reduce outside noise very well.
They stick far out your ear.

Other Thoughts: Sound quality mediocre. Bass is downright poor.

Pros: Comfortable, tight seal

Cons: Audio sounds muffled

Other Thoughts: These were the first ear-canal earbuds I got. I got them because I liked the cushioned earbuds, but they make the audio sound muffled to me. Not horrible, but not my ideal experience, and based on this, I wouldn't really recommend them to anybody.

Pros: Great sound quality and good bass. Cushions are comfortable and come with 2 sizes so everyone is covered. Gotta love the price!

Cons: Not every set is made equal. The sound quality can degrade after a 3 or 4 months as can the cushions. The wires are thin so they may break cutting off sound to one of the earbuds.

Other Thoughts: I've owned 6 sets of these earbuds over the last 2 years and I think the good outweighs the bad.

Pros: Low price?

Cons: Everything else. They fall out, they are uncomfortable (the white part pushes against my ears and the tube inside the cushions scratches my ear canals when inserting/pulling out) Don't even get me started about the sound quality. I'm no audiophile but I know good earbuds when I hear them. The highs are insanely bright and tinny. Also, whenever a new instrument begins to play, because of the bright highs, it feels surprising and unnatural. The base is ok, nothing special, but a bit mushy or muddy.

Other Thoughts: I was surprised by these phones, my previous pair of koss ur29's (over the ear headphones) were amazing. I ended up replacing these with a set of sennheiser CX300 which I absolutely LOVE, and the only cost 10 dollars more than these did.

Pros: These are super comfortable and don't create little pressure points like some earbuds. They even stay in place snowboarding with a helmet on. The best part is by far the sound quality. They have a high sensitivity so they're actually loud enough and the bass is AWESOME.

Cons: Haven't found any yet.

Other Thoughts: I had a pair very similar to these before but the cord got ruined and I will definitely buy Koss again. Comfortable and best bass for earbuds. I can't do without them.

Pros: Low cost

Cons: Horrible sound quality. Ear cushions are supposed to fit in the ear canal but fall out easily. I bought Sony ear buds for the close to the same price and they are way better.
