On the positive side:
- A good sound (adjustable for its natural or artificially boosted bass)
- Insulation quite correct (no need to burst the eardrums to hear his music on the subway).
- Correct size and comfortable for use
- Finishing and design that looks sustainable
On the negative side:
- Adaptation time to the first use because the keys must be "guessed" no physical mark can not be felt with the tips of need, except the volume control.
- No "hold" button to prevent accidental starting of the helmet, or even worse: Resetting the headset (obligation to re-associate the headphones with different devices). The cover provided is aesthetic but does not protect against accidental support. The pads can be rotated 180 ° to ensure a flat storage.
- Fingerprints on the controls (glossy black)
I do not regret my purchase outside of accidental pressing problems during transport, but since it never leaves my neck on the go, problem solved!
