The headphones were delivered for about a month. The package was well packed. I ordered it for fun and for use with a smartphone. They fit well on the head. After several hours of continuous use, the ears did not get tired. The sound quality was a pleasant surprise. I compared the sound of these headphones with the Beyerdynamic DT 770 PRO and Sennheiser HD 600 i have. The Oneodio sound is pleasant. The sound is balanced in terms of frequencies, with a predominance of low frequencies. The stereo scene is clearly visible. I connected headphones to esi maya 44 in a PC, in a FiiO X1 II player and in a smartphone. They reproduce different genres of music equally well. The microphone in the wire gives good speech quality. I am satisfied with the purchase. Thanks to the seller.
I'm very satisfied... good quality
