Not easy to choose knowing that between 10 and 100 one can fall on a quality similar components in différents.Celui then walking packaging. I wanted to voice recognition (convinced of the efficiency of the function with my Android smartphone) and I realize that it is a bit heavy to keep the ears, forcing the same spacing to try to decrease the préssion (small head size 55/56). W7 and W8 tested. On W8 I activated the "tape recorder" function and created an audio file via the casque.Les customer feedback is accurate: Bass dominant enough to have made a "nasal" voice.

I could also do without the accessory that brings together the two output jacks (headphone + microphone) into 1 because ultimately my laptop 2 separate entrances éxistent. Either I myself happen or would use it for other purposes, or I would look for a really light headset, knowing how to be forgotten because it is the microphone that bonus for me this dictation ds use.
