They have noise canceling and I am satisfied with this product! They are super strong and are resistant to fraying. I ordered it 11/16/17, received 11/27/17. Poor construction and materials, I dont recommend to buy it. Não faço questão de muito frufru não. Le ho prese su richiesta di mia mamma e posso Co fermare che vanno bene. Soooo, I disabled the preamp and went with a pyle pp444 so i could properly ground it. No he podido ni modificar el sonido ni la cancelación de ruido, ni para estos ni para los H9i. One minor issue, the latches holding footrests in place are rather small, so the kid can get his foot loose with a well aimed upward jerk. But these guys suck.
