Overview
Large dynamic drivers in sealed over-ear cups give this wired headset its monitoring character, and two plug sizes let it connect to phones, PCs and mixers. The cable detaches and the frame folds into a woven case.
The reason to look at it is the flexibility of two jack sizes plus a replaceable cord and a case. The limit is the plastic build and the lack of any wireless option or water resistance.
Who it's for
Mixing at home, DJ practice and music listening on PCs or phones all use the two jacks. Gym users, commuters who prefer wireless and professionals who need a documented flat response should look elsewhere.
Pros and cons
- Two plug sizes
- Foldable with a carry case
- Sound isolation from sealed cups
- Wide frequency range listed
- Not water resistant
- Folded size not listed
Performance notes
Cup isolation cuts room noise for the wearer, which is what makes quiet detail audible while monitoring. A detachable cable can be replaced when it frays, and the larger plug avoids an adapter on mixers and interfaces.
