Beats Solo 4 Frequency Response (measured on a B&K 5128)
Click a line or a legend entry to highlight it. Click again to clear.Tap a legend entry to highlight its line. Tap again to clear.
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
