Cancelling most of constant noise in environment, wear it for long hours.
Feels great on your ears
Cons Quality issues with headphones
Cable is too short
Summary So, I've had these headphones for about 30 days now. Truthfully, I had fallen in love with these after only a couple of hours of listening to them. For me, that's a really big deal; because prior to these SL300s, I tried the SOL Republic Tracks, the Creative WP-350s, and even the Soul by Ludacris SL150s. They were all fantastic in their own respective ways, but I couldn't stand to have any of them on my ears for more than an hour. These SL300s are the exception.
Pretty much, everyone before me has commented on how great they sound. These headphones do sound amazing. You can listen to them with the noise-cancelling on or off (powered or non-powered). Like other reviewers have mentioned, these sound their absolute best with the noise-cancelling feature turned on, as every sound in the frequency range that these 'phones can produce is amplified. To achieve that same effect and fullness of sound with the noise-cancelling turned-off will require significantly more volume from the output source. Still, these 300s are huge headphones and will probably completely cover most peoples' ears. Noise-cancelling is excellent, and even when powered-off, their noise-isolation capabilities are pretty good.
The SL300s are nicely-packaged, and come with lots of additional accessories that add value to the product. Having a choice of 2 different audio cables expands the possibilities for how I can use these 'phones. I do not own an Apple product, and my Android phone is extremely selective when it comes to mobile headsets. So, I can use the deleted in-line control cable, instead. This cable option allows me to use the 300s with pretty much every portable device I have. The other cable with the in-line controller on it is exclusively for Apple devices, but the play/pause/answer/end/mute button may work on select Android devices. Also, I really appreciate the fact that the 300s are foldable, and come supplied with a hard travel case. It even has a D-ring on it, so that you can clip it to your backpack. The included polishing cloth is a nice touch, but I probably won't ever use it.
The 300s were supplied with a set of 2 AAA batteries. I got about 25-30 hours of use from them, before replacing with a fresh set. I never got them to the point where the power indicator started flashing, but I felt like the sound was lacking, so I replaced them anyway. The "illuminating logo" feature that these 'phones have is incredibly cool, and makes for a nice "halo" effect when worn at night, or in dark places. I really, really like this feature.
There's a whole lot of good that I can say about these 'phones. I can't think of anything bad to say about them, except that they're gigantic and probably shouldn't be worn outside. I would hate to have them knocked-off my head just to fall onto concrete pavement. Still, these are incredible headphones, and I don't feel the least bit guilty for buying them. I hope that my review helps you in your quest for finding an affordable entry into pure audio bliss.

Good luck, and jam out!
Pros Undoubtedly, SL300 is one of the most beautiful cans ever seen. Although the material is plastic, it's well executed. You don't get the cheap feeling. In terms of sounding, the bass is acceptable and the resolution of mid-high is surprisingly clear.
Cons The mid range frequency response of SL300 is low in amplitude while the bass and high is high in amplitude, which cause the strange(hollow)sounding in some occasions. Besides, the performance of active noise cancellation is mediocre.
Pros Great looking headphones, overall sound, and bass in particular, is stronger and cleaner than others. Music with bass beats will blow you away, must hear "Bossy" by Kelis and "Oh" by Ludacris and Ciara on these!
Cons While bass is a 10 out of 10, mids are an 8 and highs are a 7. Vocals are more accurate for male vocalists than female. High end treble is a little too prominent and can be shrill on certain tracks, but can probably be fixed with EQ settings.
Summary Despite being slightly critical regarding the mids and highs, these are GREAT headphones and the BEST in their class. While these wouldn't be the choice of an audiophile for home listening since I would not describe them as transparent, I will describe my listening experience with these as EXCITING. The noise isolation is excellent, the overall sound is clean and everyone within 100 feet will know you are wearing really cool headphones. If you want to say "Wow" when you listen to music and have $300 to invest in portable headphones, buy these.
Pros Style it is set up in.
The comfort of the headphones.
Also it looks nice.
Cons Needs batteries.
Pros Noise canceling works ok. Good battery life. Many accessories supplied.
Cons Loose bass, honky sounding cause mids and highs are off balance and recessed.
I guess sound chambers and internal circuitry need to be re-designed from the top.
Summary Total rip off! Stay away from those.
