FIT: Both my three year old son and I feel the headset comfortable. Extended wear is not a problem.
Bluetooth connection: The connection with a Samsung Tab 2 and an iPad Air worked fine. The headphones had no dropouts up to about 25 meters, if there are no obstacles between the headphones and sound source were. In the house with concrete walls and ceilings looks different: Because after a few meters may be closing.
OPERATION USING HEADPHONES: Different keys are attached to the right ear cup. Here, for example, the volume can be adjusted and a song be bound back is not quite as simple. Schön is the announcement at power, how much battery life you have roughly even.
SOUND HEADPHONES: The headphones Scots pretty good from that blocks external noise. I've heard language and music of different styles from classical to pop to rock sample. Pure language reverberates something. I think the listeners are more for friends of pathetic, bombastic music or movies if sentiment should pay. Such pieces as Queen, Unholy or soundtracks à la Gladiator sound voluminous with a rich bass. For me personally the bass is often too dominant, my son likes. Quieter songs do not sound bad, but tends to be more dull than clear.
CONCLUSION: High-quality headphones with great Bluetooth range, which are more suitable for powerful music.
