Lab data
How we test ›Objective measurements from the SoundGuys test lab — overlay other models to see how this one compares.
Beats Solo 4SoundGuys Headphone Preference Curve
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

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.
✓Liked: Spatial Audio with head tracking, Color options, Battery life
✕Could be better: Comfort, Fit, Sound quality, Price
