I bought a FENGRU Diy PT52 16mm 32ohm before. This OPEN HEART Metal headset has the same appearance and sound quality as the FENGRU Diy PT52. The two products seem to be the same. A low-priced and amazing earphone with a very warm sound, a spacious sound field, and a heavy bass! !!
these headphones are horrible. DO NOT BUY. Sound quality is terrible. you can barely understand what is being said and the sound is much louder on one side over the other. They are simply useless. They are going right into the trash. DO NOT BUY
