As the thread title says I'm looking for some full size headphones that allow as close as possible to natural hearing of external sound-i.e- zero isolation.
I wear headphones a lot, including when I'm out and about . At the moment I use sennheiser px100-II .When you place these headphones on your hears their is virtually no noticeable difference in sound isolation .Thus any music i listen to blends in with any other sounds in my environment .
I'm wanting this same openness though with a full size headphone . I can only ask for advice here because it's very difficult to gauge weather a headphone is fully open or not .Some that are sold as open still may have some isolation properties .
No guessing please, only direct experience with headphones you own .
Which are fully open?
