JBL Tune 520BT 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
If you're looking for barebones on-ears that just work, it's hard to make a case against the JBL Tune 520BT. It sounds decent, is affordable, and does exactly what's on the label. It's just gravy that its modern electronics grant the use of features like Find My, rapid charging, and Fast Pair.
✓Liked: Sound quality, Price, Folds up for easy storage, Several colorways
✕Could be better: Clamping force, No wired listening options, App necessary for mobile use
