Serve faithfully for 2 years, taking into account that my daughter constantly beat them, dropped them, twisted the microphone into a snake, when she was younger, she even gnawed at the microphone . they steadfastly endured everything, but today the microphone failed, or rather, it began to refuse . Went to the store and bought one! Before them, the experience was with many class headphones from 500r to 1000r, but everyone lived a maximum of 4-5 months. These are the most durable option!
