Pros: Got these to replace an ailing set of MDR-NC33/BM bought 2 yrs ago. These work as well and allow me to listen to media and hear every nuance while commuting. I sit in the back of the bus over top of the motor so there is a lot of ambient noise.
Cons: There is no 'monitor' button as on the MDR-NC33/BM. I have to temporarily turn off the unit to hear announcements and such. This can become annoying at times.
Summary: I bought them on sale. The HVAC in my office makes an annoying noise. I wear these and turn it on without playing a music, and the HVAC noise noticeably turned down! Almost silence... I am happy with it.
Summary: I found these worked very well on two flights lasting more than 20 hours each. Battery life was good. Reduction in ambient noise was very good, provided the ear pieces were fitted properly and inserted well. The reduction in ambient background noise allowed for a much lower volume setting on the entertainment system and contributed to substantially less fatique on such long flights.
Summary: Great quality sound for the price and the fact that they're ear buds. Great lows and mids, highs are only ok. Portable, with the handy bag it comes with. Don't use them on the go because... A. They cancel noise and you need to hear things to not get yourself killed. B. The battery box makes it hard to walk around with them in. Great for blocking out noise in a coffee shop, home, plane or office.
Summary: I bought these on sale for the purpose of using them on flights only. They were fantastic and were able to cancel out the engine noise. I also had no issue with ears getting tired or other problems that people complain about although my flights averaged about 4 hrs in duration. I would definitely buy them again.
Summary: These earbuds are good only if you're looking for headphones that specialize in one thing, and one thing only: Noise-cancellation. Beyond that, there's not much here. It's definitely not on the "better than my high price range gear" level. If you listen to music frequently then these headphones are NOT for you. Although they do have clear mids and highs, the lows are extremely lacking. In-fact, the bass sound is almost non-existent!
Summary: Amazing quality sound, great noise cancelation. The only downside is the length of the cord. I found myself literally tripping over it sometimes. This is probably the only reason that led to its downfall of 2+ years of use.
Summary: I never expected them to be very good because of the price but these are better than a fair amount of the more expensive ones that I have had. As it says on the box it cancels out low frequency noise but not as much high frequencies such as voices FYI
Summary: I've been looking for a affordable noise cancelling earbuds to use solely during air craft flights to watch movies and I was completely satisfied and impressed during my recent trip. How they work: the first stage of the noise reduction is how the buds fit into your ear. Just putting the earbuds in drops the sound of the jet engines by 50%. Switching on the noise cancelling function takes a 2-3 seconds to kick in, but then it drops the ambient noise by another 35%.
