Worth trying if regular buds hurt your ears
348222
I had to replace my Altec Lansing Bliss Platnium ear buds, which had a great fit (too bad I lost sound out of one side) .  Since the Altec ones are no longer available, these seemed like the next best choice.  They are OK, definitely better than regular size ones, but still a little too snugly with the caps that they come with.  However, after I replaced the caps with ones from my old Altec Lansing buds, they fit great.  If you are looking for fit, try these.  You can get better sound quality from other buds, but great sound isn't worth it if your ears are killing from over sized buds!

Typically any headphones with earbuds that actually go in the ear are really painful for me. These are no different. I'm hoping different tips will make the difference.

Good sound quality. Didn't come with instructions but it was pretty easy to find a manual through Google.

Twist your head, jump, whatever. These buds actually fit slightly down inside your ear. Very comfortable. And they stay put.
The sound is better than traditional buds because it is inside your ear. They are not too tight and come out easily if pulled.
LOVE THESE! I have purchased 5 so far and have given them to my friends and family - who love them too!

The marshmallow ear buds are the only ear buds I use. I have sensitive ears and all others I have tried to use hurt the insides of my ears. These remind me of the earplugs used at the shooting range. You just give them a nice squeeze and pop them onto your ears, they slowly expand to the natural curves of your own unique ear areas. Very comfortable and the sound has great quality.

I can see how molding these are tricky.  I love to have ambient noise, music or a book on tape. However, my ears frequently get sore.  These cure that problem easily.  I would suggest picking up some good earbuds from monoprice and then using these babies.  I would recommend to anyone.

Other reviewers thoroughly cover how well these bud fits keep your buds in your ear, but there is a great added benefit not covered much here; they eliminate cord vibration. By that I mean that they nearly eliminate that sound that feeds into your ear as the cord rubs against your shirt. This alone makes them worth it for me to buy a second pair for my favorite headphones. I already have one pair of bud fits that are going strong after several years of use.

The ear buds are a little big, but I felt the sounds was very good and they require a lot less volume from whatever device you are using to be very loud. The button works, but the clicking isn't very satisfying or crisp. If you really want the good stuff, you have to get one that goes into the ear canal, but I can't stand those. These are one of the best ones of the non-canal ones that I have found.

I received these ear buds with my BB BOLD. They have good quality sound. But I found on extended use that they were not that comfortable in my ears, as they are a little larger than most buds (i.e. for my IPod). Also, the rubber caps have come off several times and remained in my ears, so I have had to remove them and there is now a sharp edge on the buds (that appears to be there to hold these rubber caps), adding to their uncomfortable fit. I am looking for replacements now.... Will keep these around as a back-up, but they aren't going to work for my main buds...

The medium size ear buds have made my experience listening to music more enjoyable. I have small ears and the original ear buds hurt me and detracted from the fabulous BOSE sound; now I listen for hours.

I had been looking for a quality pair of noise reducing ear-buds to listen to at work that had great sound and great reviews.  I ended up purchasing the Nyrius NAEB500's after a little research and some positive reviews.  However, after trying them a few times I started getting throbbing headaches.  The way these ear-buds work to get the un-distorted bass is by creating a suction in your ear drum with the rubber surrounds of the buds. It's a great concept, but for me personally, it built up a pressure in my ear that started to get painful after listening.  I switched back to my normal apple ear-buds with no issues.  This might not be typical for others, but it made these unwearable for me.

I have a problem with most in-ear buds hurting my ears after a short time. These are super comfortable and sound great. The only downside is that the wires tend to separate from the buds, or an earbud dies within a fairly short time. Still, they are inexpensive so I keep buying them.

I like to use in-ear headphones for multiple consecutive hours, and unfortunately these are designed to be wide and short, so if you insert them into your ear canal to get a proper fit, the edge of the metal digs into the outside of your ear canal. The only way I've been able to wear them without this happening has been to use a pair of Skullcandy large tips since the Skullcandy tips extend further from the metal edge and allow me to insert them far enough without the metal having to go partway in. However, the large tips do not really fit, so I've had to sacrifice sound quality for comfort.

I would also like to note that, for the lay listener (like myself), the bass on these is not that strong. Audiophile forums say the bass is "heavy" or "punchy" but in reality, they are about 75% as intense as the Skullcandy Ink'd earbuds I'd hoped these could replace (after I lost them). I would recommend Skullcandy Ink'd over these; half the price at non-online stores, and the earbud curves in at the end so there's never a sharp edge digging into your skin.

Edit: I've had them for a few months now and they sound quality is great, at first the earbuds seemed a bit to invasive since the go in deeper than the usual earbuds but you get use to it quick. The default buds are the best in spreading the sound in your ear. When having only one plugged in the ear they tend to fall quick.

After many attempts, finally found the best ear buds

I picked these up cheap on another site, and wanted to share my opinion. I'm a bit of an audiophile so I'm picky about my tunes. Let's just say I can't listen to the radio because it sounds bad to me. I like nice clean sound; not too much bass or treble. I guess my goal is to find some cheap buds that can take the place of my expensive Weston UM2s while I'm doing things that could damage them. Now I can tell you these do not even come close to my UM2 or any high-end buds for that matter. They sound OK, but you need to tweak the EQ to get them there. My UM2s are best listened to with the EQ off or flat. I tested these with my iPhone 3Gs which is not the best device in the world for accurate sound reproduction but pretty good. I used many sample tracks from the following music types. Alternative, Blues, Classic Rock, Country, Latin, Rap, Reggae, and Soul. The music I used for this test was all encoded from original CDs using iTunes MP3 codec at 192 which should be standard for most listeners. One sample SVR: The Sky Is Crying was encoded in a Lossless format and is one I use regularly for testing. With these buds it is hard to tell the difference in quality between the 192 and Lossless samples. That is a bit sad, but is a common problem with many brands. I recommend you use the "Loudness" or "Treble Booster" setting on your iPhone or iPod for the best sound these buds are able to produce. This is true for all of the music samples I tried. Any other setting left these sounding muddy with virtually no highs, or distorted. When using the settings I recommended these actually sound pretty good, but better at high volume. It's like they hide the potential they do have until you crank them up...

The Good:
The price (at least what I paid)
Construction looks good.
Cloth wrapped wire gives them a nice vintage look
Small size
They will plug directly in to the original iPhone without an adapter
Sound is on par or close to it (using my recommended EQ settings) with most buds like Skull Candy
3 cushion sizes for better fit
comfortable
Nice retail box with a hint of "Apple"
Lifetime warranty claimed by the manufacturer

The Bad:
Sound is muddy without tweaking the EQ
Some unverified (by me) claims of poor customer service
Made in China which means material quality and craftsmanship could be questionable (my opinion with some experience to back it up)

Overall:
These are good buds if you can get them at a good price. I would say a reasonable price would be $10 or below. The max would be $15 because there are comparable buds in the $5 to $15 price range.

I love the base response of these ear buds.  They're better than anything I've tried since including the normal iPod headphones and Altec Lansing's UHP326NP.  I received these as a gift and probably wouldn't pay the price that they go for.  But that being said, again, the sound is fantastic.  I have similar problems with wires' protective covering fraying near the plug and also it's gone on my left ear bud.

Personally, I don't like the hard type of ear buds. They are very uncomfortable and constantly fall out. When they do stay in my ears, the sound was ok good. The mic is also clear. However, I couldn't get over the comfort of these headphones.
