Question: Bose QuietComfort 15
Document: I've demo'd a few different noise-cancelling headsets/earbuds, and this set performed astoundingly worse than the other options. All I have to say is "wow" - the other options are just so much better.Compared against:(1) Bose QuietComfort 15 ($$$):  No comparison. The Bose were MUCH quieter - you feel like you're in a bubble with only your thoughts to keep you company.
First off, the noise cancelling feature is non-existent. So know that going in if you are still thinking about purchasing. Compared to the Bose QuietComfort 15 Headphones, these are tin cans. The bass in the JVC is very poor as well. Don't expect your hip hop or electronic music to sound as it should. I would describe the quality of sound as comparable to the free airline headphones you get on a plane. The construction is one step up from airplane quality headphones though.
I purchased two pairs of these headphones for some lengthy air travel. They were comfortable and the controls were easy to use. They folded compactly. The sound, on my laptop and over the airplane sound system, was decent.As for noise reduction, were they as good as the latest model (QuietComfort 3, for $350) from Bose? No way. Were they close? No way.
For the price this is an absolute steal. If you want Beats & Bose quality headphones go spend that money. If you hold those two headphones to a 10 out of 10 scale. These are a solid 8! Considering you paid for them for less than 10% of the other two you're getting away with robbery. However you can definitely tell the difference between these & Beats or Bose (Compared with Studio Beats & Bose QC 15). The sound quality & noise cancelling is better in the two higher end.
I bought these somwwhere other than Amazon, but was not satisfied with the comfort. I wore them about 15 minutes and my ears hurt like heck. The sound is good, but the hurt cancelled that out.
The result is the headset weighing on the top of your head and squeezing in your ears, so you wouldn't want to wear them for any extended period of time - and you look absolutely ridiculous to boot! I can't imagine that these could fit anyone's head well. I would not recommend buying these, I'm going back to my Sony $15 earbuds.
I purchased these headphones after reading a glowing review about them. However, I found them to be uncomfortable on my ears after about 15 minutes and the sound quality was good, but not great. My $20 Koss headphones from Radio Shack sound just as good. I didn't think the noise reduction feature was that good either  and couldn't tell any difference in the two NC settings that is supposed to be a unique feature of these phones.
If you can't afford to spend $300 on Bose noise canceling headphones, then I would give these a try based on the performance and value!
These headphones do not block any more noise that normal headphones would block. In this case you get what you pay for. I am returning these and investing in the real thing (i.e. Bose).
You're not buying a Bose headset here, remind yourself of that when you get them. There is a significant difference in loudness of ambient noise but it really is only about 75%. The price is right though. They work great for the money.
