Review on Sennheiser HD 660 S: Ultimate Hi-Res Open Back Headphone for Audiophiles by Ae Rim Ra ᠌

Hello everyone, today I want to tell you about Sennheiser HD 660 Audiophile Headphone. My first open headphones, I really liked it. The sound is excellent, I connect it through an external sound system, as well as to the output from the guitar processor. I am very pleased with the headphones, many songs started playing in a new way, I plan to buy wireless ones for trips (if someday all this covid darkness will end)
