Pros: great sound quality and the headphones them self are built great!
Cons: ..... the wires are terrible, i was listening to them today and the headset fell off my head, when i went to grab them then wire underneath the coating about 6 inches down from the headpiece broke, i tried to reconnect them and solder thinking it would be a quick fix, nope, now the right ear piece won't work.
Summary: I did research on these Headphone and wish I had followed other peoples advise. The sound quality is really good but after about 4 week with only casual use at home the plastic hinge on one side cracked and the headphones fell apart.
Summary: I purchased these earphone for a specific reason. I wanted a set of earphone that had a wide frequency range at least below 8000 up to 25000. This product provided these requirments. However, once I got the earphones, the left channel had a faulty connection. One has to manipulate the lead cable and fix it with a paper clamp to keep it in place otherwsise only the right channel can be heard.
Summary: When I first got these headphones, I noticed the sound was great - good bass and dynamic range, and certainly as loud as you could want! The closed back style blocks most outside noise (be warned though, I have been unable to hear fire alarms over these things!) allowing a much more immersive experience. However, I also noticed that the 'phones were uncomfortably tight.
Summary: Light weight. Low bass power is surprisingly good as is the dynamic range. Really provides punch to the sound. Headband is a little tight, which might be a bit much for some after wearing for a while. Update--Earpiece broke off after 2 months, by then I found wearing them for more than half an hour was difficult because they were so tight.
