Sennheiser HD 660S2 features and price
The Sennheiser series appeals to audiophile audiophiles. Thanks to its open and circumaural design, it provides clear and clean sound transmission. The Sennheiser HD 660S2 can be considered the best model in the series. In this regard, there are no features such as active noise canceling, wireless connectivity, but it is higher than the AirPods Max price.
Headphones using a 300 ohm transducer can reduce the frequency to 70Hz. Open design can be a problem, especially in crowded spaces, as there is no noise cancellation. It can be used with two cable exchanges with 0.25 inch and 4.4mm jack inputs. You can get its full capacity when you connect it to a booster with a 1/8 inch adapter. The Sennheiser HD 660S2 headphone model, which does not have any application, will be sold with a price tag of $ 400.
