The verdict
This is not the set of headphones you buy because you want bang for your buck. There are a very narrow range of needs these headphones suit, and you'd be better served waiting for these to go on sale before considering them.

Lab data

Beats Solo 4SoundGuys Headphone Preference Curve
Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.

Passive isolation (dB) with ANC off — how much ambient noise the fit blocks on its own. Higher on the chart means more attenuation.
