+ Superior sound insulation
+ A better definition, although typical of armature transducers
+ Very compact and very comfortable to wear
+ Solid design (I do my jogging with)
+ The iPhone controls for this price ...
- The bass is a little behind (this is often the case with entry frames)
- Acute also ... (ditto)
To be a little hi-fi enthusiast, I find the quality / price ratio super good.
After about the bass, there still and worst of the worst you'll need a few days to get used to ...
For me the sacrifice worth it at this price, you avoid headaches and gaining immersion.
