The stereo imaging performance of the Sony WH-H910 is satisfactory. There’s a slight bump in the weighted group delay occurring in the lowest frequencies, but that shouldn’t be too noticeable overall, with the rest of the range falling beneath the audibility threshold, ensuring a tight bass and transparent treble. The L/R drivers are fairly well-matched in regards to amplitude response, but some minor deviation is present in frequency and phase response, which has a slight impact on the headphones’ ability to accurately reproduce the placement of objects in the stereo image, generating a less immersive listening experience in turn.
