Result, almost no sound insulation. Literally forget this model for use in noisy environments (gym / transport etc.).
Forget also for use "at the office" because the insulation in the other direction is as bad (even more than conventional earbuds) and colleagues may not appreciate.
Otherwise the sound is very good for the price.
In short, I recommend this purchase only for people who make bike trips / jogging in the city, the fact that the insulation is poor will benefit from a safety point of view for this type of activity, and type tower ear is best suited to the sport.
