negative points:
- Sensitive to wind, in active mode, amplifies the noise of a strong wind and becomes annoying
- Greatly reduces the bass sound, does not cancel, and is very effective for medium and treble
- Does not completely cover the ear due to its dimension
Positive:
- Boosts bass in active mode, very nice
- For my urban use, it is great against the noise of cars, works, trains, public transport
- Full of other sony users (passive model) and does not attract the attention of thugs (compared with prestigious brand names)
- After 3 weeks of use, always strong and impeccable
- Has a button to pause the music smartphone
- Has a microphone that makes handsfree, very convenient to meet and talk confidentially
- Finally, despite its weaknesses, it deserves the 5 stars because for that price ...
