Summary: Great sound, very comfortable. I also have the bigger Bose headset and find they make me warm. These do not. Would highly recommend for someone who does a lot of traveling, they come in a nice compact case, with charger.
Summary: you know this headphones always sound great, old, new, haven't heard of a bad review for this QC3. Ear cushions are replaceable, along with wires or battery if you need to find a new one. I recommend a US seller versus foreign seller, just my choice. Love the lightness, sound effects with the noise cancelling technology. I would have given 4 stars but I haven't tried the QC15, over ear headphones yet,but,a Bose is a Bose. Aloha.
Summary: Great product, good sound, noise cancelling is better than most of the "on the ear" headphones. I used several brands SONY, Panasonic, with noise cancelling, the QC3 is much better, you get what you pay for.
