The base of these tricks is completely insane! They can make your head shake.
Having said that, I would like to give a somewhat deeper review than just saying that the base is good.
There is a clear and good sound on the headphones that delivers a good balance between treble and bass on the lower levels of the bass control. Is the audio book you should listen to with a bass reader, yes, these headphones are not for you. On the other hand, if you watch movies, listen to music and listen to the radio, these headphones are very nice.
The bass control is conveniently set to change if you switch from music to voice calls or movies. When listening to popular music usually, the bass controller will probably end up setting at 0-30% for not shaking and letting go of the headphones. The actual button for adjusting the base feels plastic and is slightly loose. From experience, I know that this model is the same and I have tested more fools of the same model with the same feel in the button.
The call quality is good, sound sound and the microphone does a good job. The other end does not mean that you have headphones on you without the microphone picking up your voice very well. There is both microphone on the supplied cord, but even if you drive wirelessly there is a microphone built into the cover.
40 hours of battery life ... 40 HOURS! Crazy!
Building quality feels solid and solid. Nice cups, good buttons, metal strap in the bracket, proper padding in the covers, good soundproof and well balanced in weight.
All I miss is active noise reduction, but the covers are so well insulated that they shut out a lot of ambient noise anyway.
