It reproduces compressed audio sources such as streaming, MP3, and Bluetooth transmission codecs with a spacious and excellent sound. It is compatible with the dedicated app "Headphones Connect," and by using the "Equalizer" that allows you to customize the sound quality to your liking, you can choose from eight different presets such as "Relaxed" and "Bass Boost," or customize the equalizer settings to your preference. These headphones feature smooth, low-rebound urethane foam ear pads that minimize wrinkles. The soft, comfortable ear pads provide a lightweight and comfortable fit.
