I tested the headphones:
* The iPad with Traktor DJ
* The MacBook Pro for listening to music
* At a small mixer
Positives:
* Very flexible
* Balanced, clear sound
* Good workmanship
* Very good price / performance ratio
* Practical spiral cable
* Small folding
* Attractive design
Negatives:
* No adapter on 6,3mm
* Cable not interchangeable
For the two negative points I put in relation to the positive points from a star.
Conclusion:
The headset is highly recommended for its price!
I hope the cable holds a couple of years.
A 6.3mm adapter is needed, however, for nearly every mixer
(One has indeed usually, in my opinion, but is part of a "DJ" to headphones.)
