Question: Do the ear buds fit well?
Document: These buds fully met my expectations for use while running with my iPhone 3GS. Sound quality was surprisingly good. The in-ear fit provides a good deal of acoustic isolation--poor man's noise reduction. Likely because of this, I found the bass response quite good and max volume to be uncomfortably loud.The fit, as many have said, will vary but the standard plugs fit me fine and stayed in quite well while running--no issues.
I just picked up a pair of these, and so far I'm pretty impressed. Overall they sound pretty good. The bass is decent, but not overly boomy like some. The treble is very clear and can be a little thin on brighter songs, but not bad by any stretch. They are a HUGE improvement over the stock Apple buds that came with my iPhone 3GS both in terms of fit and sound quality. They block out environmental noise pretty well and the cords don't make too much noise when moving.
When I do get a fit, it only lasts for a bit before loosening. Given that it's so hard to get a good fit, the sound quality often suffers as well since a seal can't be formed with the ear canal.
These headphones are great. They are so much more comfortable in your ear than the standard earbuds. They come with several size adapters to custom fit your ears. The sound is noticeably better as well. I also like volume control feature.
These are the only headphones I've found to be worth the over-$15 pricetag.I've gone through a lot of headphones, and these are my favorite. I've bought them again (I accidentally broke the first pair). They fit well into my ear. They don't fall out while I'm walking. They don't feel to big/invasive.Favorite part: the remote.
I know that ear sizes vary, but go ahead and try the (3) different size ear buds to get a better fit. Mine sound awesome. Yes, just as good as other Sony buds I have had in years past.
Having got an iPhone 5, I was hoping the new earbuds would be better than previous gen but they were not. Actually worse, IMHO. These however are fantastic, for the price. Fit in your ears well and 3 sizes are included. I guess you could say they cancel out some noise due to how they &#34;plug&#34; you ear.
I have small ear canals and most headphones fall out of my ears and these are great. These earbuds are comfortable, they fit well (and stay in place!) and they are lightweight. They have a convenient remote control on the wire so I don't have to pull my ipod out of my armband when I run. These are a great product at very reasonable price; I highly recommend them. I'm on my 3rd pair (I keep losing them).
I am using this for my iphone and I love these. The headset that comes with the iphone is great with the controls in the cord but the ear buds kill me because I want to jam them in my ears so I can get loud sound. These fit comfortable in my ears and I can't tolerate the sound all the way up so that is already a bonus. Controls on the cord are awesome.
)I won't really speak to the fit of the earbuds, because obviously it will be different for everybody; except to say that the medium earbuds fit fine for me out of the box, and I suppose that I have relatively normal-sized ears. I've used other in-the-ear buds which felt better, but these were acceptable to me.The headphones measure 48" from earbuds to headphone jack.
Answer: They came with 3 different size silicone buds that you can change out.  I think I have relatively normal size ears and the medium and small work really well for me.  The silicone is really flexible so you can get a very nice fit.  The only issue I have had is that sometimes they fit so well I can't hear anything except what I'm listening to.  At work I only wear 1 ear bud in most of the time or else my coworkers scare me to death when they come into my office and I don't notice.I-pod ear buds I have found to be slightly too big and they start to hurt my ears after awhile.  I haven't had that issue with this type of ear bud at all and can't imagine using a different kind.  My husband uses the large silicone buds and he has slightly odd shaped ears and many other types don't work well for him at all.
