Odd shape, terrible low end 
2008-08-12
After using these for 3 weeks I can now confidently say that I am thoroughly disappointed with my purchase. My main gripe is the bass response... and I do have them inserted correctly in my ear. Although the mids and highs are great the bass is just so weak that most songs sound boring and lack depth. If I listened to rap it would be even worse.
The cord material is stiff and the way it comes out of the speaker is just retarded. Also the odd shape of the speaker/housing causes it to droop and fall out of your ear unless you use the foam inserts. There are 9 sets of inserts and I hate them all. My old sonys came with just one but they were perfect!
I'd love to smash these headphones with a hammer into little pieces but then I'm reminded that they cost $70. The only positive thing about them is the noise cancellation works very well.
Excellent sound quality.

Never having used in-ear phones in the past I wasn't quite sure to expect. The only other earphone that I have extensive experience with is a vintage pair of Stax SRX-Mk3s. The E2c was the specific model that I was interested in, mostly in part due to Siegfried Linkwitz' study on reference earphones ([...]). After discovering that the E2c was no longer available I settled on the SCL2. While they do not sound as good as my Stax reference headphones, the SCL2 does sound mighty good. Their level of isolation and comfort using the supplied foam pads is excellent. Overall I am extremely pleased with my purchase.
Very Good Buy 2008-06-14
I just got a pair of the Shure SCL2 Sound Isolating Earphones in black and I have to say they sound really good with my iPod and laptop. They don't perform as well as my other set, the Shure SE530's but what do you expect when you compare what $500.00 buys you versus $69.00 or so. These are for me to wear exercising, riding my bicycle, and doing yard work in (which I don't dare do wearing the SE530's). All in all, the bottom-end Bass response is more than adequate and the SCL2's produce clear and pleasing high-end reproduction. A good buy!
Very Good Sound; Incredible Customer Service 2008-06-13
I just received a pair of these (in a clear styling) that replace a set of e2s I bought a couple of years ago. They're at least as good, and I suspect (as others have noted) that they'll improve somewhat after the break in period. The fit is good once you find the right match for your ears from the many included options, and unless you are *really* into sound you are going to think these are just great. I'm sure there are people who care a lot more about fine points of sound than I do who will be able to find flaws with these, but there's a point of diminishing returns for me around about this price point, and these are far and away the best I've found in this range.
Most importantly, though, this company totally blows me away with their customer service. My old e2s were about six months out of the very generous two year warranty, but had, about a year ago, started to very infrequently drop out in one ear -- probably a short in that ear's wire. It happened so infrequently that I ignored it until it got worse, and then these were out of warranty. I returned them with a note explaining the situation, and two weeks later got a brand new pair of these in the mail. It is pretty rare to find this kind of customer service, and it definitely factors into my five star review and my loyalty to this brand.
thank goodness for the warranty! again! 2008-06-12
I'm on my second pair of Shures. The first were E2's that the right side just quit working. They were probably 10 months old. Now I have SCL2's which they sent me instead of the E2's. I'm 8 months into owning them and the LEFT side is now DEAD. I don't think I'm hard on earphones; I just use them at the gym and walking and the bulk of the time is talk podcasts! I guess I'm glad they have a two year warranty, but it would be nicer if they just made earphones that would last for at least a year, for these prices. They'd get 1 star if they didn't stand by their warranty. I'm beginning to wonder if cheap earphones replaced over and over wouldn't cost the same or less than shipping these things back over and over....
excellent warranty and product 2008-04-28
The Lightweight SCL2 features single dynamic microdrivers for full sonic range and resonant bass.
Great Company and Earbuds - Can't Beat Them for the Price 2008-04-25
I had e2c's, and the wires started to crack (this is a common problem that Shure knows about- it has to do with the type of plastic that is used for the insulation and the way it reacts with certain skin chemicals, but ther's no better material available). Shure replaced them for free under the 2 year warranty. The e2c model has since been replaced by the more expensive se2's, but Shure has re-packaged the e2c's as the SCL2. According to Shure, they are the same phone, just repackaged. But...
I agree completely with the previous poster who said that he feels that these sound better than the e2c's. The bass IS deeper, and the sound overall is more detailed and richer. Maybe because they are new? I don't know... all I know is I am very happy with the SCL2's.
One change that I do not like- the hard case has had the inner spool removed, so you no longer have anything to wrap the cord around. I wrap it around my fingers and then jam everything into the case. It goes in fine, but is a mess when it comes out. Shure yanked the spools because they were finding that people were wrapping the cord too tight and causing premature failure of the wires.
Shure's warranty program and service is outstanding. My new phones arrived only 1 week after I sent in my old ones. I just wish I had kept the old case :( but that's really a personal choice kind of thing anyway.
Better than the E2c 2008-04-10
I got a pair of E2c's from Amazon 22 months ago and got quite a bit of use out of them. About one month ago I noticed that the wires were cracking near the ear pieces which exposed the conductors. I didn't think they'd still be under warranty but I dug up my paperwork and they were; two whole years later! Anyway I sent them into Shure and less than two weeks later I get a pair of SCL2's in the mail.
Appearance-wise they're identical to the E2c pair I had. This time however I tried using the clear plastic ear pieces and I don't know if it's them but these immediately sound better than the E2c's. The bass is richer and it seems like the midtones are fuller.
While the E2c's were great I was never that impressed with the sound, especially compared to my sealed Sennheiser HD280 Pro headphones. However these SCL2's compare favorably. I would get them again and I would buy more Shure products as they have a great product and super customer service.
Worth Every Penny 2008-04-01
Straight out of the container I would have rated these are POOR POOR POOR, not only no bass but just plain FLAT. I plugged them into my computer and had the MP3 player play one song in a hoop all night. Put them on in the morning to find I had full sound other than bass so I started playing with ear pieces until I had full sound. For those with little bass take your time the bass is there. I'm using the soft rubber ones and a different size in each ear. I have had three so called noise canceling headsets and other than the over the ear heavy sets this set blocks out noise or talk.
If you're "MOVING UP" from the E2C, you might reconsider 
2008-03-31
I've used Shure E2C's for about 4 years (2 pairs). My most recent pair finally started wearing through the wire coating, and I have too much pride to just electrical tape them (not to mention there are dozens of holes in the insulation). I should note that purchased the clear version of these earphones, but am posting where most of the reviews have already been made.
So I decided it was time to replace the E2C's and wanted to see what my options were. I looked at the Shure SE110's and SE210's, but didn't find many favorable reviews (especially when juxtaposed with the E2C's). I peaked around at other brands but decided I've been too happy with Shure to risk it.
I settled on the SCL2's, assuming they were somehow better than the E2C's, given they are the "Pro" version of the same phones.
My initial reaction is that the sound is more homogenized than the E2C's. I don't feel like I'm listening to the band play live, I feel like I'm listening to them in The Matrix. The sounds feels more synthetic and less real. Given that I've used the E2C's for years, I confident the fit is not the issue; my ears know where they are supposed to fit.
I have read that there is a break-in period for these earphones; I tend to believe that as I've seen break-in periods on all types of speakers (car, home, computer, etc.) I'm 3 weeks in today, and I just hope this break-in doesn't take much longer.
All in all, the phones are very good. After listening for about 30 minutes, I don't really notice the sound being odd. If there is a lack of anything, I would say its treble, as I've had to play with the EQ a bit to get the highs where they should be.
If I had the choice, I'd probably move back to the E2C's. I'm still confident though that these SCL2's will break in.
That's my review for now. I'll do my best to come back and update this in a couple months, hopefully after the break-in.
>>>> UPDATE (6/4/08): Sure enough, the break-in did wonders for the sound quality of these headphones. I would now say these are at least as good as the E2C's, and I would buy these again without hesitation.
Another note is that the cord on these phones seems much more durable and flexible than the E2C's.
