The elastic thread does not stay tied very well, but that can be solved with a couple of stitches. Just be careful of the back part of the top of the bench (where the hinges will go) (piece 9 in our instruction booklet). Functional. La verdad no esperaba mucho de unos audífonos de este precio, pero puedo decir con seguridad que ha sido una excelente compra. tunes everything else out The quality of this headset is fantastic, it dont feel cheap but it feels as if it is built to last a long time. Conclusion: these headphones are surely geared towards higher end fashion oriented individuals who also appreciate great sound. It is made from Paulownia wood which you don’t see many things made from that type of wood here in the US. Nice headpiece! And yes lots of fun!
