What does the sound quality and customization look like?

Sound is tuned for clear everyday listening and can be personalized using the Sony | Headphones Connect app, which includes EQ Custom to adjust tones to your preference. The headphones also support DSEE-like upscaling to improve perceived quality of compressed tracks, delivering fuller detail from streaming sources.
