Review on Sennheiser HD 660 S: Ultimate Hi-Res Open Back Headphone for Audiophiles by Bi i Dng (MC) ᠌

After some hesitation, I did not change the old Sennheiser HD600 for them, Got pros: Detailed high-resolution sound found in all Sennheiser 600 series studio headphones. Balance cable included. They are swayed not only by stationary equipment, but also by players with a strong telephone output (for example, Ibasso DX160), which is greatly helped by a cable with a 4.4 mm balanced plug. Got cons: The difference in sound compared to other Sennheiser 600 series studio headphones is minimal. The weakest sound dynamics of the entire 600 series. At the same time, the price is 30% higher.
