The Beats Studio Buds Plus have a somewhat neutral sound profile. They deliver adequate bass, so mixes have thump, rumble, and boom, but a peak in the high-mid makes vocals and instruments sound harsh. On the downside, they don’t have any sound customization features to help you adjust them to suit your preferences.
We had some trouble getting the right bud to stay in place and form a good seal in our test rig’s ear. The movement of the bud shifting out of place causes the right driver to have a different measured response in the bass range than the left. However, this issue is unique to our test rig; in daily life, both drivers will match.
