Summary: used Koss 20$ headphones made a solid connection to my ear cannel and really made the bass pop in my ear i would advise using those, only problem with those is the wire sometimes comes out of the ear-bud, other then the listed con's these headphones are on an "ok" level if your looking for something quick and cheap.
Pros: fits in ear well, long cord, high volume.
Cons: L shaped headphone jack, doesnt form secure suction to form a tight fit to the ear cannal to give that great quality bass sound.
Summary: They're sufficiently comfortable, as they come with three sizes for the ear plugs. They also come with a small (about 2.5" x 5") smooth black pouch, apparently for carrying the headphones. While it is definitely better than throwing them randomly in a pack where they may get damaged, the bag itself is very thin and not wide enough to easily put the headphones in.
Pros: I am not very familiar with much variety of audio-related technology, but from my untrained perspective they are very good.
Cons: While the quality may be great, the bass isn't noteworthy. They're just fine for everyone however, unless you really care about heavier bass.
Summary: For the price I think I would have liked to purchase something else. I use ear-buds for commuting on the bus to get to school, walking through downtown, and general laptop use. I'm finding these 'buds to only be worth using while I'm stationary on my laptop, or on the bus. They just aren't good for walking around because of the ambient noise of the volume-knob slamming around.
Pros: Decent sound, long cord, carrying case, lightweight, self-volume control, fits in ear well.
Cons: The cord has terrible memory problems, it seems near impossible to straighten it out after coiling. Partly because it's in a single housing, instead of two, and partly because it is super light and just doesn't have weight to straighten itself out with.
Summary: I know a number of earbuds have them but the slider on the cord is nice to drop the volume quickly without having to pull out my phone/ipod.
Pros: Excellent quality on all levels... fits comfortably in the ear without the soreness that can come from other ear buds. I was surprised by the quality of the lows. I've listened to everything from Pandora to lossless audio and been very satisfied!
Cons: I've liked the noise canceling in my Shure ear buds better. These do a decent job but not as much as I would've liked. But for 50.00 I'm not complaining.
Summary: For those that are not familiar with earbuds, be sure to test the different sizes, make sure they are in the ear all the why or the sound will be empty or lacking bass. Always adjust your sound, EQ setting for the very best results.
Pros: Absolutely wonder sound, big upgrade over OEM earbuds. Tight deep bass, very good meds and highs. These sound much, much better than the low cost Skullcandy earbuds and as good as the high end models.
