Stu:NZtechfreak: Regards an ANC headphone with truly great sound and comfort? Doesn't exist. The Polk UltraFocus 8000 are the best sounding ANC headphone I've heardheard, but not the most comfortable. If the ANC and travel aspects are important I'd be looking at the QC25. I believe they sound better than their predecessor.Would something like the Oppo PM-3 passively block enough noise to negate the need for ANC? Could they be an option for travel? Maybe I'll just have to keep my eyes on Bose pricing over the next couple of weeks. Cheers
If you're listening to music any reasonably sealed can will block out sound for you, the leakage the other way may annoy your neighbours however. The PM-3 aren't too bad for sound isolation, but that depends on the seal the cups form - they are slightly on the smaller side, so for me with mildly larger ears they are partially on-ear and don't isolate as well as they might for others. The Senn Momentum 2.0 seal better with a larger internal dimension to the cup and memory foam cushions. If you are talking passive noise reduction when not listening to music then none of them will be that good, but they will take an edge off the airplane noise (~75-80dB in the cabin generally speaking).
