Sound: the positive first: the sound is really great for this price range. Acceptable bass (you can not expect miracles here nech), quite clear treble, the mids are available, but a bit "spongy". But so it still sounds better than many on-ear KH I've tested lately and would have cost some of the 5-fold to some worlds.
Shield: and here the major shortcoming of this headphone: the screen is exactly zero. Zero. Unavailable. One hears _everything_ from outside, just as if there were no headphones. That's so annoying that I currently hardly listen to music on the go, at least for me. If people next door 2 also entertain just quietly, you can hear their conversation still more clearly than their music. Who puts on shield value: Stay away here! Who needs it anyway where the entire environment will notice a completely headphones: Here you go, here he is.
Comfort: it well does not fall out of your ears. But that's about the best that can be said here. Revolves repeatedly saying so off that the music down and the outside noises are more annoying. You have to turn back into position, press firmly, correct ... Also at some point used to be as hard to push him in the ears he -so finally a little Rela- that it actually sometime uncomfortable suppressed and hurt him every few minutes , So pain or permanently hindrehen off ^^
Have been thinking, if I put my ear muffs over it when I'm with that thing outside. The combination can then probably sound replace a 100 Euro headset, looking for bissl stupid and some will wonder, how long has the Peltor Optime as headphones * g *
