Performance and User Experience

• Comfort: Highly praised for being "feather-light". However, some reviewers note that because they are an on-ear design, the pressure on the outer ear can become fatiguing after about two hours of use.
• Sound Quality: Described as having a "balanced sound profile" where vocals are clear, though it may lack the depth and soundstage of more expensive over-ear models.
• App Integration: Users can extensively customise their audio experience through the Sony | Headphones Connect app, which includes a 5-band equaliser.
• Noise Control: These headphones do not have active noise cancellation (ANC); they rely solely on passive isolation.
