Very good product. Excellent quality for the price. The headphones fit perfectly in the ear and do not exceed. Unfortunately lasts 3 months (daily use) before the sound let me go left (recurrent problem with all my headphones after ... max 6 months) due to play at the jack is to say that if we maintain the wire in position while it's good but in the pocket while walking, it cuts at all not because the jack tip is straight and the wire is more or less tense.
