To:
- Accessories books (3 cables, a bag, a jack adapter)
- Foldable (very compact), the atria pivot in all directions
- Impecable finish, solidity and durability sensation
- Superb sound, relatively neutral
- Versatile headset also fits well has electro, jazz, rock, or classical
- Quality unbeatable price
- Good insulation
- Easy driver (good rendering even on smartphone)
Against:
- No hard case
- No cable smartphone
- Quality plastic helmet but it is neither very handsome nor design
In short I would recommend it to anyone with a hesitant one ear Sennheiser Momentum, philips fidelio m1, focal spirit one, Marshall monitor. Having tried all none can beat the m50x except the design level.
