No issue with the product - just doesn't work well for small ears

Sound quality is great, as expected from a Sennheiser product. I hoped that this style of earbuds would not hurt my ears as all others have done as they don't sit inside the ear canal. I'm not talking about volume; the plastic edging physically hurts inside the ear after about 20 minutes. Unfortunately these must join the pile of others I've tried over the years. No issue with the product - just doesn't work well for small ears.

I bought these for use with my digital piano. The sound is very good for the price. Unfortunately, unless you have incredible small ears the phones don't fit over your ear and instead pin your ears to your head. Its quite uncomfortable. If they weren't so inexpensive I would return them but I'll just use them until I find ones i like more.

It works fine but is a teeny bit large for my ear.  If this isn't an issue, then the product is a winner.

They are easy enough to pair with my laptop but they would not stay in my ears.  This may not be the products fault I might just have weird shaped ears.  The sound is okay- not phenomenal but okay.

I am always searching for the perfect set of in-ear headphones, so I jumped at the chance to try these new Philips headphones.  For whatever reason, in-ear headphones just will not stay in my ears, I think it is because I have small ears and perhaps my ears have an off shape.  I've tried many different types and sizes -- small, large, foam, hard case, rubber tipped, and none of them work.

The difference with the Philips in-ear headphones is that the tiny speaker is oval shaped, not round.  The headphones come with three different sized soft caps, I chose to use the smallest size.  To insert them in my ears, I actually stretch the opposite hand over my head, and that seems to get a good angle.  These headphones will stay in my ears through light activity -- so watching a TV show or listening to a podcast at my desk. They would not stay in for me while running, but if you normally don't have issues in-ear devices, they may be OK for you to use in more vigorous activities.

I am not a sound expert at all, but for the average user, the sound is good.  There is not a lot of background noise, no funny noises when you move, and I found voices and music to be clear and true.  This still is not the perfect in-ear headphone, but it is very good and well worth the price.

These headphones are not adjustable to make the head size smaller.  They don't really stay in place, so it is hard to hear the music when working out.  I found some $7.00 ear buds at Target that work really well.

Sound is decent - the fit of the earbuds on the other hand sucks. I had to buy additional disposable smaller pieces to try to get a correct fit on these - or - you can buy custom molded earbuds for these for lots more money which spent make me happy. Put the small pieces I the set people! Is it so hard to believe people have small ear canals? I have small ears.

The headphones work great for blocking noise.  I use ear plugs as well. I have small ears and still have trouble getting them in a comfortable position. Maybe they could have a little larger cup.

Sound quality is really great, but the buds are completely round and they hurt my ears after wearing them for a while. Im not a little girl so my ears are even average size. They don't keep out background noise like I had hoped but they aren't really noise-cancelling headphones. All in all, they are a good product, but if you have small ears, I'd think twice about getting these.

UPDATE 2/15/12: To add to my previous review, one of the headphones quit working. I was using them while running and now sound only comes from one of the headphones. They are only about 7 months old. I am not pleased with these and I wouldn't order them again.

The sound quality like most skullcandy headphones is great, but if you have small ears like me they can get uncomfortable quickly.

The sound from these headphones was amazing while I had this product. I didn't quite get to break it in but the sounds was similar to the beats [beats were somewhat better] but for the price this was an amazing product. However I had to return mine as the product was irritating my ears. Amazon took the product back, excellent customer service on their part. If my ears were smaller I would have definitely kept the product as it sounded amazing. For those of you who do not have big ears like I do, this product will work very well for you.

I have small ears and these headphones were a bit too large. Also, the charging case leaves something to be desired. Otherwise these headphones are exactly what they say they are.

The Bluetooth works as expected, and is a convenient small size overall, with the exception of the ear piece which will not fit in my ear canal so just hangs on my ear loosely.  I have to use the ear hook as the loops will not keep the ear piece in place.  I do have small ears, so it you have the same, then you may want to consider another option.  Otherwise the Bluetooth keeps its charge well and the sound quality is very good. (when I hold it snug to my ear).

I loved the sound quality but it just seemed that my ears were too small for the smallest earbud. Unfortunately, I have to return them.

These work fine but I must have a small head because the speakers don't fit exactly over my ears.

I have small ear canals. Always looking for the next best thing to put on my earphones. for me, either the foamy things, or the smallest version works... the bigger multi-cone thing fits, but was not as comfortable. The foamy things are better at blocking out sound.

I'll admit I have small ears, but these would literally fall off if I moved my head around too much. I returned them within a day. The sound quality was fine, they just didn't fit. I wish they came in more than one size.
