I received these earphones about a month ago, and as the title indicates, I find them to be really great.
The design allows them to remain flush with the surface of your ears and provides a stable fit. I personally use the black foam tips and find them to be comfortable to wear for a few hours (although it did take 2 or 3 days to get used to them)

The sound quality is amazing with the mids and highs being the strong points. The bass is present and noticeable but sometimes lacks a bit of punch in some electronic & hip hop tracks (Rock music is perfect when paired with these eaphones)

Build quality leaves no room for improvement, as Shure didn't cut any corners here. Cable is thick and flexible (and replaceable!) and the earphones themselves are solid. The one thing I do not like is the fact that they come with a soft carrying case, which seems to offer almost no protection when compared to the hard cases Shure used to have. It's a carrying case, not a protective case

Having a pair of Shure E2C's for years, and after countless solder, and patch repairs on them, I decided to crack open my wallet and buy a new pair. I researched and read, and looked, and him-hawed back and forth, until I decided I would try the 315's. If I liked them, move up to the 425's.

I came home early from work, so I could sign for them, and get to work listening. The foam tips preinstalled, mediums, would not seal, so I went to try another smaller set. I ended up shredding the foam, as they had seemed to have melted to, or frozen to the stems. The first set of small rubber tips, didn't do the job either. To make matters worse, when I went to take them out, the left bud came off, wedged inside my ear canal. I had to wait an hour before my wife came home to retrieve it with a pair of tweezers.

The medium, large, small, foam, rubber, all failed to provide me with a good seal.

I sent for an RA, and received one, hating knowing I was about to lose money on an ill fitting product. Then to add insult to injury, the dog found the box, with the spare tips in it, and tore it to shreds. So now I am stuck with a pair of ear buds that will never be used.

Guess I will just have to repair the E2C's a few more times until I find someone who will let me audition a good pair.

These were exactly what I wanted. I am so pleased with them. I play drums and these earphones allow me to hear my clicks or music from the other band members.

I have been a Shure customer for 7 years, and I can say from experience that these are really solid earphones. I started off with the E4c's, and I can say that this model is definitely a step up.

I was debating whether I should get the 2 series, 3/4/5, and then I realized that after using something for more than 3 months, the feeling of buying a higher up model diminishes when you are already at a premium brand.

As such, I feel that the 3 series will give me the best bang for the buck. While the 4 and 5 might be "better" in terms of specs, I ask myself - will I really hear music that much better if I have 2 drivers, or even 3 drivers, as opposed to one?

All in all, I am satisfied with my purchase and look to be a repeating customer of Shure and Earphonesolutions in the future.

I had Bose,Klpsch, sennhieser and tried first time SE315 and it is amazing quality with base. I

Starting with the strong points, I was quite impressed with the design and build quality of these earphones. They felt very well built and durable, sit relatively flush in my ear, and the replaceable cables that allow rotation/swiveling are definitely a nice touch as I've had many earphones fail in that area (and to my chagrin usually after the warranty expires and/or losing the receipt). It has the balanced armature trait of being very detailed and precise throughout the range it reproduces. If I had to nitpick, I would say the smallest rubber eartips could be a tad smaller or made of a softer material as I noticed a bit of discomfort with extended wearing since I have small ear canals and usually use the smallest tips on any earphone. The memory wire in the cable could be a bit stiffer to hold its shape better. Inserting them is a bit difficult, but felt really secure especially if you wear them with the cable routed behind your head with the cable coupler thing snugged up close to your neck.

Ultimately I had to exchange them mainly because the sound was just not my cup of tea. The tonal balance sounded really off to me, with a very prominent midrange, especially lower midrange. It sounded pretty good with Rock, but other genres weren't as good including Classical. A lot of times female vocals had an almost cupped hands and in your face sound instead of just being up close. Bass was also lacking, but mainly because of the strong midrange, if I had the volume up to where the bass was "fun" the midrange became overpowering and overall SPL too loud but if the midrange was right the bass was anemic. They did seem to need some time to break in, at first listen the bass seemed totally missing but even after hours of use the bass only improved marginally. Details in the highs were nice, they did not seem nearly as lacking as the bass relative to the midrange and I never noticed any harshness.

clear sound, nice base, wire is just a little heavy around the ear.

I have owned many Shure ear monitors over the years. The quality is great, support is terrific and the sound quality is wonderful.

I tend to stick with Shure--I know what I'm going to get. It's so hard to judge headphones, particularly earbuds, because there is really no way to try lots of them out before buying. These were a trade-up from the EC3s. They're better. I just loved the clarity of sound, pure, unaffected, perfect. Modest bass--no problem there, I have no interest in having my ears blasted out--but it creates a feeling of someone performing in front of you. There is an impressive mid-range presence. You can't really go wrong here. These are terrific.

I'VE HEARD SOUNDS THAT I DIDN'T KNOW EXISTED ON SOME SOME SONGS I'VE BEEN LISTENING TO FOR YEARS. THESE EARPHONES DO REALLY ISOLATE THE SOUNDS. THEY ARE HOWEVER A LITTLE UNCOMFORTABLE. THE PRICE IS LITTLE MUCH.

I've been using the SE315s for a good month and I'm totally enamoured of them. I've owned a couple of pairs in the past, and the sound quality is awesome - true highs, great bass.

My only complaint with the previous pairs is that the cords tend to fray or disconnect at the earbud (I'm hard on equipment), but thankfully this has been resolved with the 315s: the new cords have a much sturdier, moldable cord that can be disconnected from the earbuds, making for easier replacement.
