They work as required Buono il suono che è rapportato al prezzo, discreti i materiali che dopo soli 4 mesi hanno ceduto, ovvero, il perno di metallo della cuffia sx si è sfilato e quindi si è staccata dal resto. They are very light and I often forget Im wearing them. Made my room so much more organized and less cluttered. These are a dream come true! The sound on it is surprisingly good. I got the blue with palm leaves, and I am going to be purchasing more! The backs of the cabinet slid neatly into grooves instead of needing to be tacked on with tiny nails. So far I tested the USB Headset and I like the sound on it. They help a lot!
