Summary: A tight seal
Comment: These ear buds are definitely a great buy. They cancel out a lot of background noise when walking outside by a road or the beach. I love that the buds come in different sizes because I have small ear openings and the buds that came with my ipod are too large. I continuously wore these for a couple of hours and did not feel any discomfort. The only thing with having such a tight feel is that it does feel like a suction cup in your ear. But I guess that is a price to pay for quality of sound you get from these ear buds. I highly recommend this product!

Summary: great headphones
Comment: These are some good headphones. They are light so you won't even feel them. The sound clarity is crisp and clear and they really do deliver some serious bass. They're a steal at $20 and being someone who takes headphones very seriously, I can say that they are better than some headphones that are 5x their prices.

Summary: Zophotos
Comment: The sound is great, but they keep falling out of my ears. They don't come with interchangeable rubber inserts, so they aren't a comfortable fit. Given this situation, I can't use them for the gym as I had originally planned. I use them when I'm sitting still on flights for business.

Summary: Best earphones I've ever owned.... until they stopped working. -_-
Comment: I've been through about $200 worth of head/earphones at this point in my life and I have to admit that these are the best I've ever had. Unfortunately, they're probably also in the list of one of the quickest ones to break. While I do admit that I probably use earphones not in the most common way that they would be used... like for example sleeping with them on and letting them fall to the floor and not picking them up until I need to use them again... these stopped working when I was doing none of that (not that I didn't do those things while they were alive, mind you). They were on my night table, had been there for a couple of days and it was late at night so I had to use them. Picked them up and WAM! Left earphone didn't work. GRR! Right now I'm using a tape to be able to listen through both sides.
I did notice that the high levels bass on these, so if you REALLY don't like that you definitely need not apply. However, I used these to listen to movies, music, etc. on my laptop and/or with my MP3 player, I thought the bass was quite nice. I usually don't use bass if there's an option to turn it on or off, but these definitely did not make my enjoyment of music, etc. less pleasant. These are also really good for canceling out noise, which is something I like. Oh and I guess it should be noted that when I plugged these into my laptop at full volume, they really blasted out the music really high. So you might be careful before wearing them and the device you're using them with being at full volume. Might make you deaf from what I can tell.
All in all, my only quibble with it is their very short durability and this is a big issue with me as I tend to buy new headphones every other month. They offered great sound, nice bass and they were quite cheap too. So unless you're very careful when using these, I wouldn't even begin to recommend them.
